Aim: Smoking is harmful to human health. However, the relationship between smoking and blood pressure (BP) has not been consistent. This study aimed to analyse nurses' smoking behaviours and their relationship with BP. Methods: This cross‐sectional study recruited 128 009 nurses in 11 cities in China. They were surveyed with questionnaires including BP measurements. The main contents of the questionnaire included smoking status and other factors that might be associated with hypertension. Multiple linear regression analyses and binary logistic regression analyses were used to analyse the data. Results: The results showed there was a significant difference in the smoking rate among nurses with different characteristics (P < 0.05). For both male and female nurses, smoking was associated with increased diastolic BP and mean arterial pressure, but only with increased systolic BP of male nurses. The prevalence of hypertension among male and female nurses was not related to smoking. Conclusion: Despite a relatively low overall smoking rate, rates among some groups are high. Different cities, hospitals, and departments can combine local data and conditions to formulate targeted tobacco control measures to improve nurses' physical and mental health. Summary statement: What is already known about this topic?: The number of tobacco‐related diseases has been steadily increasing worldwide over the past few decades.A decrease in the smoking rate of medical staff can lead to a decrease in the smoking rate of the general population.The association between smoking and blood pressure remains controversial, and further clarification is required. What this paper adds?: There was a significant difference between the smoking rates of nurses with different characteristics.The smoking rates were relatively high for nurses in emergency departments and operating rooms and those with >10 night shifts per month within the last 6 months.Among nurses, smoking is related to increase in diastolic blood pressure and mean arterial pressure in both men and women but only to increased systolic blood pressure in men; however, there was no association with hypertension risk. The implications of this paper: This study can support nursing managers to take targeted interventions to target smoking populations to reduce their smoking rates.For nurses who smoke due to high pressure, it is suggested that the working hours and cycles should be adjusted appropriately, the proportion of nurses should be increased, and the work intensity should be reduced to alleviate the work pressure.Nurses with high blood pressure should especially be dissuaded from smoking.

BACKGROUND: Work-related musculoskeletal disorders (WRMSDs) and ergonomic risk factors are very common in bakery workers. OBJECTIVE: The purpose of this study is to (1) assess the prevalence of musculoskeletal disorders among bakers because they use automated machines or traditional baking, and (2) to determine the strategies to prevent musculoskeletal disorders in bakers. METHODS: A systematic review of PubMed, Scopus, and Web of Science was conducted from the beginning to February 4, 2022, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Mesh keywords and phrases were used to execute the search strategy. Information on MSDs and ergonomic risk factors in bakery workers was collected. Two reviewers worked independently on study selection, data extraction, and paper quality ranking. RESULTS: This study identified 14 papers from seven countries. Although the prevalence of MSDs in bakery workers has been studied, only a handful of them have been studied ergonomic risk factors, and the findings have been very limited. The association between different risk factors and MSDs seemed significant compared to many other occupational diseases. The traditional bread-baking system and lack of mechanization may increase the risk of MSDs in bakery workers. CONCLUSION: WRMSDs for bakery workers have been less studied than other occupational diseases. Our systematic review found several significant relations between the factors influencing the prevalence of MSDs. This study also showed the comparison of traditional and modern cooking systems with diseases of the upper limbs, shoulders, and back pain as possible fields for future research.

Background: Human communities suffered a vast socioeconomic burden in dealing with the pandemic of coronavirus disease 2019 (COVID-19) globally. Real-word data about these burdens can inform governments about evidence-based resource allocation and prioritization. The aim of this scoping review was to map the cost-of-illness (CoI) studies associated with COVID-19. Methods: This scoping review was conducted from January 2019 to December 2021. We searched cost-of-illness papers published in English within Web of Sciences, PubMed, Google Scholar, Scopus, Science Direct and ProQuest. For each eligible study, extracted data included country, publication year, study period, study design, epidemiological approach, costing method, cost type, cost identification, sensitivity analysis, estimated unit cost and national burden. All of the analyses were applied in Excel software. Results: 2352 records were found after the search strategy application, finally 28 articles met the inclusion criteria and were included in the review. Most of the studies were done in the United States, Turkey, and China. The prevalence-based approach was the most common in the studies, and most of studies also used Hospital Information System data (HIS). There were noticeable differences in the costing methods and the cost identification. The average cost of hospitalization per patient per day ranged from 101$ in Turkey to 2,364$ in the United States. Among the studies, 82.1% estimated particularly direct medical costs, 3.6% only indirect costs, and 14.3% both direct and indirect costs. Conclusion: The economic burden of COVID-19 varies from country to country. The majority of CoI studies estimated direct medical costs associated with COVID-19 and there is a paucity of evidence for direct non-medical, indirect, and intangible costs, which we recommend for future studies. To create homogeneity in CoI studies, we suggest researchers follow a conceptual framework and critical appraisal checklist of cost-of-illness (CoI) studies. [ABSTRACT FROM AUTHOR]

Accessible Summary: What is known on the subject?: Physical restraint is widely used in the elderly at home, and cognitive impairment is an important risk factor. Family caregivers of people with dementia are the main decision makers and implementers of physical restraint at home.Most people with dementia in China receive home care, and family caregivers face enormous care and moral pressures influenced by Confucian culture.Current research on physical restraints focuses on quantitative analysis of its prevalence and reasons within the institutions. There is little research on how family caregivers perceive physical restraints in home care context, especially under Chinese culture. What the paper adds to existing knowledge?: Many family caregivers face approach – avoidance conflict and moral dilemmas when making decisions to restrain, and they make difficult choices in these dilemmas.In China, family caregivers are influenced by many unique factors, including traditional Confucian culture, family affection, and rural home environment.Inadequate laws and policies provide the ground for abuse of physical restraints, and family caregivers rarely consider legal and policy restrictions when using physical restraints. What are the implications for practice?: With limited medical resources, nurse‐led dementia management is the hope to reduce physical restraints in home.Mental health nurses need to assess for the appropriateness of physical restraints associated with psychiatric symptoms in people with dementia.At both organizational and community levels, improving effective communication and relationships between professionals and family caregivers are important to address. Improvements in this context require education and time for staff to develop skills and experience which is necessary to provide family caregivers with ongoing information and psychological support within their communities.Considering Confucian culture will be of value for mental health nurses working in other countries where there are Chinese communities to better understand perceptions of family caregivers. Introduction: The use of physical restraints is a common practice in home care. Family caregivers face care‐related and moral pressures due to the influence of Confucian culture in China. The use of physical restraints in the Chinese cultural environment may differ from the use of such restraints in other cultures. Scientific Rationale: Current research on physical restraints focuses on quantitative analysis of its prevalence and reasons within the institutions. However, there is little research on how family caregivers perceive physical restraints in home care context, especially under Chinese culture. Aim: To explore the perceptions of family caregivers on physical restraints in people diagnosed with dementia receiving home care. Method: A descriptive, qualitative study of Chinese family caregivers of people diagnosed with dementia in home care. Framework method analysis was adopted using the multilevel socio‐ecological model. Results: Beliefs about benefit lead to a dilemma for family caregivers. Cherishing family's affection encourages caregivers to reduce physical restraints, but lack of help from family members, professionals and the community forces them to restrain their loved ones. Discussion: Future research should explore the complex issue of culturally specific physical restraints decisions. Implications for Practice: Mental health nurses must receive education regarding the negative outcomes of the use of physical restraints for family members of people diagnosed with dementia. A more liberal approach to mental health and relevant legislation, which is an emerging global phenomenon that is currently in an early phase of development in China, grants human rights to people diagnosed with dementia. Effective communication and relationships between professionals and family caregivers can contribute to the establishment of a dementia‐friendly community in China. [ABSTRACT FROM AUTHOR]

Objectives: This systematic review and meta‐analysis aimed to determine the prevalence of loneliness and social isolation among informal carers of individuals with dementia and to identify potential influencing factors. Methods: We conducted a comprehensive search across 10 electronic databases, including PubMed, Cochrane, Embase, Web of Science, PsycINFO, CINAHL, Scopus, Chinese Biomedical, China National Knowledge Internet, and WANFANG. Our search strategy covered the inception of the databases up to September 16, 2023, with an updated search conducted on March 8, 2024. Prevalence estimates of loneliness and social isolation, presented with 95% confidence intervals, were synthesized through meta‐analysis. Subgroup analyses and meta‐regression were employed to explore potential moderating variables and heterogeneity. Results: The study encompassed 27 research papers involving 11,134 informal carers from 17 different countries. The pooled prevalence of loneliness among informal carers of individuals with dementia was 50.8% (95% CI: 41.8%–59.8%), while the pooled prevalence of social isolation was 37.1% (95% CI: 26.7%–47.6%). Subgroup analyses and meta‐regression indicated that various factors significantly influenced the prevalence of loneliness and social isolation. These factors included the caregiving setting, study design, the intensity of loneliness, geographical location (continent), data collection time, and the choice of assessment tools. Conclusions: This study underscores the substantial prevalence of loneliness and social isolation among informal carers of individuals with dementia. It suggests that policymakers and healthcare providers should prioritize the development of targeted interventions and support systems to alleviate loneliness and social isolation within this vulnerable population. Key points: Informal carers of people with dementia contend with unique circumstances that render them susceptible to both loneliness and social isolation.There is a significant prevalence of loneliness and social isolation in informal carers of individuals with dementia.Several significant moderators influence the prevalence of loneliness and social isolation among informal carers of individuals with dementia.Moderator analysis can guide targeted interventions and support systems for at‐risk informal carers of people with dementia to alleviate loneliness and social isolation.

Background: Despite the historically low smoking prevalence among Chinese women, there is a trend of future increase. Purpose: We systematically reviewed the correlates of smoking among Chinese girls and women. Method: We conducted a systematic review of literature on correlates of smoking among Chinese women using Medline and China Academic Journals databases. Following the PRISMA statement, two investigators independently searched for literature, identified and reviewed papers, assessed the quality of the papers, and extracted information. The characteristics of studies and correlates of smoking were synthesized separately for youth and adults. Results: A total of 15 articles (11 on adults, 4 on youth) met the inclusion criteria. Based on these studies, peer smoking was the most consistent correlate of smoking among Chinese girls. Among Chinese women, partner smoking, job-related stress, and exposure to cigarettes made for women were consistent correlates of smoking. Knowledge of harms and negative attitudes towards smoking were found to be negatively associated with smoking. Conclusion: Overall, the evidence base for smoking among Chinese women is limited. Although smoking among Chinese women is still at an early stage, it is becoming more prevalent among specific population subgroups, such as rural-to-urban migrant workers. Although further research is needed, findings from the current study provide a roadmap for research and policy on prevention of smoking among Chinese girls and women. [ABSTRACT FROM AUTHOR]

Investigations have found maternal adverse childhood experiences (ACEs) cause an intergenerational danger to their children's health. However, no study has investigated the effects of maternal ACEs on behavioral problems of preschool children in China and gender differences on these effects. This paper aims to investigate the role of maternal ACEs on behavioral problems of preschool children in China and explore gender differences as related to these behavioral problems. Stratified cluster sampling method was used to select 7318 preschool children from 12 districts in Hefei city, China. A questionnaire survey was conducted to collect information on maternal exposure to ACEs and Conners' Parent Rating Scales. Logistic regression was used to analyze the relationship between maternal ACEs and children's behavioral problems. The prevalence of behavioral problems in preschool children was 16.0%, while it was higher among girls (18.4%) than boys (13.92%) (χ2 = 27.979, p < 0.001). The rate of behavioral problems in children in the group of mothers with ACEs was higher than those without ACEs (all p < 0.05). Maternal ACEs were associated with increased risk of the behavior problems in preschool children (adjusted OR 2.91, 95% CI 2.45–3.45), and no gender difference (in girls 3.01, 2.38–3.81, in boys 2.79, 2.17–3.58, respectively) was found. Maternal ACEs were associated with increased risk of each type of the behavioral problems of preschool children, except that maternal emotional neglect was not associated with psycho-physical problems, impulse-activities, and anxiety. The only gender differences found were higher conduct problems related to maternal emotional abuse and ACEs and higher anxiety related to maternal physical abuse and community violence in girls compared with boys. Mothers exposured to ACEs are more likely to have children with behavioral health problems in preschool period. Further research is needed to explore the mechanisms by which maternal ACEs influence children's behavioral problems. [ABSTRACT FROM AUTHOR]

The novel coronavirus pneumonia (COVID-19) outbreak that emerged in late 2019 has posed a severe threat to human health and social and economic development, and thus has become a major public health crisis affecting the world. The spread of COVID-19 in population and regions is a typical geographical process, which is worth discussing from the geographical perspective. This paper focuses on Shandong province, which has a high incidence, though the first Chinese confirmed case was reported from Hubei province. Based on the data of reported confirmed cases and the detailed information of cases collected manually, we used text analysis, mathematical statistics and spatial analysis to reveal the demographic characteristics of confirmed cases and the spatio-temporal evolution process of the epidemic, and to explore the comprehensive mechanism of epidemic evolution and prevention and control. The results show that: (1) the incidence rate of COVID-19 in Shandong is 0.76/100,000. The majority of confirmed cases are old and middle-aged people who are infected by the intra-province diffusion, followed by young and middle-aged people who are infected outside the province. (2) Up to February 5, the number of daily confirmed cases shows a trend of "rapid increase before slowing down", among which, the changes of age and gender are closely related to population migration, epidemic characteristics and intervention measures. (3) Affected by the regional economy and population, the spatial distribution of the confirmed cases is obviously unbalanced, with the cluster pattern of "high–low" and "low–high". (4) The evolution of the migration pattern, affected by the geographical location of Wuhan and Chinese traditional culture, is dominated by "cross-provincial" and "intra-provincial" direct flow, and generally shows the trend of "southwest → northeast". Finally, combined with the targeted countermeasures of "source-flow-sink", the comprehensive mechanism of COVID-19 epidemic evolution and prevention and control in Shandong is revealed. External and internal prevention and control measures are also figured out. [ABSTRACT FROM AUTHOR]

Background: Sexual and Reproductive Health (SRH) targets have been included as part of the United Nations Sustainable Development Goals and indictors are important to monitor progress towards these targets. SRH indicators are recommended for setting norms and measuring progress globally. However, given the diverse political, socioeconomic and cultural contexts in different countries, and lack of global agreement on broad indicators, it is important to select appropriate indicators for specific countries. Based on internationally recommended indicators and data availability in China, this paper selected four indictors to reflect SRH in China and interpreted these indictors by analyzing the underlying factors. Methods: We employed secondary data analysis and key informant interviews. Secondary data were obtained from the China Health Statistical Yearbook (2005–2017), China Statistical Yearbook (2005–2017), and the sub-national estimates of the Global Burden Diseases Study 2016. We interviewed 36 key informants at national and sub-national levels. Results: The four selected SRH indicators are contraceptive prevalence rate (CPR), adolescent birth rate, abortion rate, and availability of school sex education. CPR of married women has remained above 75% over the last three decades, indicating a high level of access to family planning (FP) services; however, unmarried but sexually active women have significant unmet needs for FP services. Although adolescent birth rates in China remain low, the abortion rate, abortion numbers, and the ratio of abortions to births increased from 2014 to 2016 while FP policy was relaxed. This suggests that abortion among unmarried women is a significant contributor to overall figures. Qualitative analysis of the availability of school sex education, reveals an absence of policy due to conservative attitudes of key stakeholders. Conclusion: Since SRH challenges vary significantly between contexts, indicators for measuring progress towards SRH targets should be selected based on country context. The CPR and abortion rate are currently available and important indicators to monitor the most basic part of SRH in China, but require modification to ensure they reflect universal access to quality reproductive healthcare by all reproductive age women, regardless of their marriage status. Policy and indicators on sex education need to be carefully developed to fit the context in China. [ABSTRACT FROM AUTHOR]

Aims and objectives: The aim of this study was to investigate the prevalence, emotional and follow‐up burden of insulin injection‐related needle‐stick injuries among clinical nurses. Background: needle‐stick injures introduce statistically significant occupational hazards to healthcare workers. Although the large proportion of the needles injuries attributed to insulin injection, research evidence about the prevalence, emotional and follow‐up burden of such injures is lacking. Design: Cross‐sectional study. Methods: 5389 nurses were recruited from 45 hospitals in Shaanxi, China, from November 2018 to July 2019. Participants were administrated with a questionnaire specifically developed for this study. Descriptive statistics were used to present the findings. Results: All 5,389 nurses responded to the survey, of which 396 (7.4%) participants experienced 620 insulin injection‐related needle‐stick injuries in the past year, representing an annual prevalence of 115.0 per 1000 nurses. The annual prevalence of infection caused by the injuries was 18.7 per 1000 nurses. The injuries occurred most frequently when nurses were recapping the needle (42.4%). In the majority (98.4%) of the injuries, the hurt nurses took proper immediate actions. However, only 30.3% of nurses reported the injuries to the administrative staff, and in 43.2% of the injuries, the nurses refused or discontinued the suggested follow‐up. A large proportion (58.6%) of the hurt nurses experienced emotional changes. Multivariate logistic regression showed that department, removing and/or setting back needle caps with bare hands, frequency of insulin pen and syringes are associated with the incidence of insulin injection‐related needle‐stick injuries. This paper is reported following the STROBE recommendations. Conclusions: This survey demonstrated a considerably high prevalence of insulin injection‐related needle‐stick injuries among clinical nurses. Even though the majority of the hurt nurses took proper immediate actions, a large quantity of them failed to report the accidents to the administrative staff and complete the suggested follow‐up. Nurses who suffered from insulin injection‐related needle‐stick injuries were subject to various negative emotional changes. It portends a statistically significant risk to occupational health management for nurses. Relevance to clinical practice: Scientific preventive and management strategies are desirable in order to minimize the consequences of insulin injection‐related needle‐stick injuries.

Background: Extensive parasitic diseases epidemiology in Zhejiang province has not been carried out since the second national survey in 2004. Therefore, dynamics in prevalence and infection pattern of the major intestinal parasites should be explored.Methods: The distribution of three parasites including soil-transmitted helminths (STH), intestinal protozoa and C. sinensis in Zhejiang from 2014 to 2015 were explored. Kato-Katz technique was used for STH and C. sinensis detection, whereas transparent adhesive paper anal swab was used for pinworm detection, and iodine smear was used for protozoa detection. A questionnaire survey on alimentary habits and sanitary behaviors was conducted in half of the studied counties.Results: This study recruited 23,552 participants: 19,935 from rural and 3617 from urban area. Overall prevalence of intestinal helminth infections was 1.80%. In this study, seven helminth species were identified including A. duodenale, N. americanus, Trichuris trichiura, Ascaris lumbricoides, C. sinensis, Fasciolopsis buski and pinworm. The average prevalence of STH infection was 1.71%: 1.94% in rural and 0.44% in urban area. Hookworm was the most prevalent infection at 1.58%: 1.79% in rural and 0.44% in urban area. Prevalence varied considerably in the studied counties. Prevalence was highest in Yongkang county at 10.25%. Only 2.79% of children from rural area were infected with pinworm. A proportion of 0.40% of rural participants were infected with protozoa, whereas Endolimax nana was the most prevalent at 0.23%. C. sinensis showed infection only in one man. Awareness on C. sinensis was 24.47% in rural and 45.96% in urban area, respectively.Conclusions: Prevalence of STH and protozoa infections declined considerably whereas C. sinensis infections remained few in Zhejiang province compared with the prevalence reported in previous large scale surveys (19.56% for national STH infection in 2004, 18.66% and 4.57% for provincial STH and protozoa infection, respectively in 1999). The findings of this study showed that hookworm, mainly N. americanus remained a parasitic threat to population health, mainly in the central and western Zhejiang. Therefore, more health education regarding fertilization and farming habits is necessary in rural areas. The awareness concerning hookworm infection should be reinforced. [ABSTRACT FROM AUTHOR]

INTRODUCTION The widespread popularity of e-cigarettes is considered an important public health concern. However, only some studies have investigated the prevalence of e-cigarette use in Shanghai, China. Research on the perceived harmfulness of e-cigarettes and public support for e-cigarette regulations in China is limited. This study aimed to estimate e-cigarette awareness, prevalence, and associated factors among adults in Shanghai, China. METHODS This study used data from a representative survey conducted in Shanghai, China, in 2019. The survey was conducted at 64 surveillance points in Shanghai, China, using a multistage, stratified, cluster-randomized sampling design, recruiting community-based Chinese adults aged ≥15 years. Based on the principles outlined in the Global Adult Tobacco Survey (GATS) China Project, data were collected by conducting face-to-face interviews in households. Of the 3200 selected households, 3060 people completed the individual survey. The overall response rate was 97.4%. RESULTS In all, 72.3% of the respondents had heard of e-cigarettes. The respondents who had used e-cigarettes at some point in their life, used them in the last 12 months, and used them currently were 5.8%, 2.6%, and 1.3%, respectively. Among adult residents who had heard of e-cigarettes, 38.2% thought they were less harmful than traditional cigarettes. The respondents who perceived e-cigarettes as more harmful than traditional cigarettes were less likely to have ever used e-cigarettes (AOR=0.2; 95% CI: 0.1--0.5, p=0.0015) and more likely to support incorporating e-cigarettes into the regulation of smoking control (AOR=3.9; 95% CI: 1.8--8.6, p=0.0008). CONCLUSIONS Our findings reveal that the awareness about e-cigarettes was high, and the prevalence of e-cigarette use was similar to the findings from previous studies in China. The harmful perception of e-cigarettes warrants further attention from public health practitioners. [ABSTRACT FROM AUTHOR]

Objectives: This paper studies the institutional inequality that exists in the prevalence of diabetes and hypertension, as well as their diagnosis and medication management, between urban and rural residency status (hukou) holders in China. Methods: Exploiting the Chinese Health and Nutrition Survey, we primarily demonstrate that while a lower proportion of rural residency holders suffer from diabetes and hypertension, a larger proportion have never been diagnosed with these conditions and do not take medicine to control them. We explore the determinants of these disparities by the non-linear decomposition method. Results: Decomposition results illustrate that a large part of disparities in the prevalence of diabetes and hypertension can be explained by the differences in demographic structure and occupational socio-economic status. Regarding the ruralurban disparity in the under diagnosis and under-medication rates, the differences in demographic structure, household affluence, occupational socio-economic status and consumption patterns make the greatest contributions. Conclusions: This evidence suggests that improving the institutional economic inequality and enhancing the occupational mobility of rural residency holders are of paramount importance to mitigate any inequality in health and healthcare utilisation.

Background: Evidence suggests that arteriosclerosis and sarcopenia (decreased muscle mass) share some of their many causes. However, after controlling for confounding factors, it is unclear whether the presence of arteriosclerosis correlates with sarcopenia. Objectives: The aim of this paper is to explore whether sarcopenia is associated with arteriosclerosis. Design: A multicenter cross-sectional community-based study. Materials and methods: A total of 2511 elderly subjects from six Chinese community health service centers in Anhui province were surveyed through an e-health promotion system to collect basic data and measurements of brachial-ankle pulse wave (baPWV), body composition, and handgrip strength (HGS). Pearson's correlation and binary logistic regression analyses were performed to identify associations between sarcopenia and high baPWV. Results: The prevalence rates of sarcopenia were 12.9% in men and 15.3% in women according to the 2019 standard of Asian Working Group for Sarcopenia. Among subjects with high baPWV, the proportion of sarcopenia was higher compared to those with normal baPWV (men: 17.7% vs. 3.7%; women: 20.4% vs. 4.9%, both p<0.001). Binary logistic regression analysis revealed that sarcopenia was associated with high baPWV (p<0.0001, odds ratio=1.619) after adjusting for confounding factors. HGS slightly and negatively correlated with baPWV (−0.19 in men and −0.18 in women). Conclusions: The intertwined pathophysiological mechanisms shared by arteriosclerosis and sarcopenia are potential targets for future interventions to reduce morbimortality in subjects with both disorders. Upcoming prospective studies and clinical trials are expected to advance these findings. [ABSTRACT FROM AUTHOR]

In December 2019, corona virus disease 2019 (COVID-19) has broken out in China. Understanding the distribution of disease at the national level contributes to the formulation of public health policies. There are several studies that investigating the influencing factors on distribution of COVID-19 in China. However, more influencing factors need to be considered to improve our understanding about the current epidemic. Moreover, in the absence of effective medicine or vaccine, the Chinese government introduced a series of non-pharmaceutical interventions (NPIs). However, assessing and predicting the effectiveness of these interventions requires further study. In this paper, we used statistical techniques, correlation analysis and GIS mapping expression method to analyze the spatial and temporal distribution characteristics and the influencing factors of the COVID-19 in mainland China. The results showed that the spread of outbreaks in China's non-Hubei provinces can be divided into five stages. Stage I is the initial phase of the COVID-19 outbreak; in stage II the new peak of the epidemic was observed; in stage III the outbreak was contained and new cases decreased; there was a rebound in stage IV, and stage V led to level off. Moreover, the cumulative confirmed cases were mainly concentrated in the southeastern part of China, and the epidemic in the cities with large population flows from Wuhan was more serious. In addition, statistically significant correlations were found between the prevalence of the epidemic and the temperature, rainfall and relative humidity. To evaluate the NPIs, we simulated the prevalence of the COVID-19 based on an improved SIR model and under different prevention intensity. It was found that our simulation results were compatible with the observed values and the parameter of the time function in the improved SIR model for China is a = − 0.0058. The findings and methods of this study can be effective for predicting and managing the epidemics and can be used as an aid for decision makers to control the current and future epidemics.

Background: In the past 20 years, the trends of ischemic heart disease (IHD) mortality in China have been described in divergent claims. This research analyzes mortality trends for IHD by using the data from 102 continuous Disease Surveillance Points (DSP) from 1991 to 2009.Method: The 102 continuous DSP covered 7.3 million people during the period 1991-2000, and then were expanded to a population of 52 million in the same areas for 2004-2009. The data were adjusted by using garbage code redistribution and underreporting rate, mapped from international classification of diseases ICD-9 to ICD-10. The mortality rates for IHD were further adjusted by the crude death proportion multiplied by the total number of deaths in the mortality envelope, which was calculated by using logrt = a + bt. Age-standard death rates (ASDRs) were computed using China's 2010 census population structure. Trend in IHD was calculated from ASDRs by using a joinpoint regression model.Results: The IHD ASDRs increased in total in regions with an average annual percentage change (AAPC) 4.96%, especially for the Southwest (AAPC = 7.97%) and Northeast areas (AAPC = 7.10%), and for male and female subjects (with 5% AAPC) as well. In rural areas, the year 2000 was a cut-off point for mortality rate with annual percentage change increasing from 3.52% in 1991-2000 to 9.02% in 2000-2009, which was much higher than in urban areas (AAPC = 1.05%). And the proportion of deaths increased in older adults, and more male deaths occurred before age 60 compared to female deaths.Conclusion: By observing a wide range of areas across China from 1991 to 2009, this paper concludes that the ASDR trend for IHD increased. These trends reflect changes in the Chinese standard of living and lifestyle with diets higher in fat, higher blood lipids and increased body weight. [ABSTRACT FROM AUTHOR]

Background: The prevalence of autism spectrum conditions (ASC) is 1% in developed countries, but little data are available from mainland China, Hong Kong and Taiwan. This study synthesizes evidence relating to the prevalence of ASC in these areas and assesses the effects of research methodology on prevalence estimates. Methods: Systematic literature searches were conducted in PubMed, Web of Knowledge, China Web of Knowledge and Weipu databases, as well as relevant papers published from 1987 to 2011, reporting prevalence estimates of ASC or childhood autism in mainland China, Hong Kong and Taiwan. Summary estimates of prevalence were calculated with a random effects model. The effects of research methodology on the prevalence estimates were assessed using a meta-regression model. Results: There were 25 studies eligible for review, 18 of which were suitable for inclusion in a meta-analysis. Pooled prevalence of childhood autism was 11.8 per 10,000 individuals (95% confidence interval (CI): 8.2, 15.3) in mainland China. Pooled prevalence of ASC was 26.6 per 10,000 (95% CI: 18.5, 34.6) in three areas. Substantial heterogeneity was identified between studies (I2>75%). The prevalence estimate of childhood autism was most strongly associated with the choice of screening instrument. After adjustment for age group, the odds ratio for prevalence estimates when using the Autism Behavior Checklist (ABC) as the screening instrument compared with those using the Clancy Autism Behavior Scale (CABS) was 0.29 (95% CI: 0.12, 0.69), and 1.79 (95% CI: 0.70, 4.55; P= 0.20) when using the Checklist for Autism in Toddlers (CHAT) compared to the CABS. Conclusions: The available studies investigating the prevalence of ASC in China, Hong Kong and Taiwan have focused mainly on childhood autism rather than the whole spectrum. The prevalence estimates are lower than estimates from developed countries. Studies using more recently developed screening instruments reported higher prevalence than older ones. However, available studies have methodological weaknesses and therefore these results lack comparability with those from developed countries. Our findings indicate a potential under-diagnosis and under-detection of ASC in mainland China, Hong Kong and Taiwan, and a need to adopt more advanced methods for research of ASC in these areas.

INTRODUCTION The home is the primary source of children's exposure to secondhand smoke. This study investigated the status and influencing factors of child exposure to secondhand smoke at home when people smoke in the household. METHODS Participants with at least one child living in their household from 10 communities in Chongqing were recruited and provided a self-administered questionnaire using a multistage proportional random sampling design from June to August 2021. The chi-squared test and binary logistic regression analyses were used to identify influencing factors. RESULTS The questionnaire completed by 1345 families showed that 631 (46.9%) families lived with smokers in their household, and 509 (80.7%) of those families reported that smoking occurred within the home while the children were present. Binary logistic regression analyses demonstrated that the time between waking up and household smokers having the first cigarette of the day (OR=0.44; 95% CI: 0.22-0.85), changes to smoking habits and behaviors within the last six months (OR=1.76; 95% CI: 1.06-2.90), attitudes towards tobacco control in the household (OR=2.91; 95% CI: 1.72-4.92), self-efficacy in maintaining a smoke-free home (OR=2.27; 95% CI: 1.36-3.79), having rules to maintain a smoke-free home (OR=3.25; 95% CI: 1.68-6.29), and the status of providing cigarettes to guests at home (OR=11.0; 95% CI: 1.33-90.8) were associated with exposure to SHS. CONCLUSIONS Education focusing on the impact of smoking on children's health should be encouraged. Smoke-free homes should be established, and smoking restrictions in the household should be enacted. Therefore, information about the available tobacco-control services should be given to family members and be used properly. It is an effective way to decrease the risk of at-home exposure to SHS for children, to overcome any obstacles in tobacco control. [ABSTRACT FROM AUTHOR]

Background: The main objectives of this study were as follows: (1) evaluate the prevalence of burnout syndrome among doctors, (2) establish associations with demographic factors in China, and (3) examine the mediating role of psychological attachment in the relationship between job burnout and career calling.Methods: This cross-sectional survey was conducted by administering an online questionnaire in May 2016. The survey was performed across Thirty provinces. In total, A total of 3016 Chinese doctors were selected as participants, of which 2617 completed valid questionnaires (effective response rate: 86.77%).Results: The overall prevalence of burnout symptoms among Chinese doctors was 85.79%. Little variance was reported for burnout symptoms according to age (Waldχ2 = 6.843, P < 0.05, OR < 1), professional title (Waldχ2 = 13.110, P < 0.05, OR > 1), and daily working hours (Waldχ2 = 7.226, P < 0.05, OR > 1). However, the burnout of Chinese doctors was found to be associated with psychological attachment (B = - 0.6433, P < 0.0001) and career calling (B = 0.3653, P < 0.0001); furthermore, psychological attachment (B = 0.2350, P < 0.001) mediated the relationship between job burnout and career calling.Conclusion: Burnout symptoms among Chinese doctors were prevalent and associated with age, professional title, and long working hours. Chinese doctors aged 20-30 experienced a much higher level of burnout symptoms. The longer hours doctors worked, the more likely they were at risk of burnout symptoms, especially among attending physicians. Doctors who endured high-level burnout tended to exhibit decreasing psychological attachment, which threatened their sense of career calling. Finally, this paper proposed related explanations for the function mechanisms based on both theoretical and practical perspectives. [ABSTRACT FROM AUTHOR]

Background Workplace violence against emergency physicians is a global concern. However, there was relatively little research on the incidence and correlated factors of workplace violence among emergency physicians in China. We aimed to investigate the occurrence and correlated factors of physical and verbal violence among emergency physicians in China. Methods We conducted a nationwide cross-sectional study from July 2018 to August 2018. We included a total of 10457 emergency physicians from 31 provinces across China in the analysis. The questionnaire covered socio-demographic characteristics, work-related factors, psychological characteristics, and workplace violence. We applied binary logistic regression to examine the correlated factors of physical and verbal violence among emergency physicians. Results The prevalence of physical and verbal violence among emergency physicians in China was 27.63% and 81.81%, respectively. Regarding socio-demographic factors, male emergency physicians with bachelor's degrees or higher, poor sleep quality, and unfavorable health conditions were more likely to experience workplace violence. Concerning work-related factors, emergency physicians who had longer years of service, worked a higher frequency of night shifts per month and served more patients per day had a greater prevalence of workplace violence. As for individual psychological characteristics, negative affect was positively correlated with workplace violence, while self-efficacy and positive affect were negatively correlated with workplace violence. Conclusions The situation of physical and verbal violence against emergency physicians in China is severe, especially verbal violence. Hospital administrators should pay more attention to the workplace violence of emergency physicians and take measures to decrease the occurrence of workplace violence efficiently, such as reducing their workload and cultivating their positive affect and self-efficacy.

INTRODUCTION While many studies have confirmed that smoking is causally associated with various diseases, some have found an association between smoking and human functional impairment. Relationships between smoking and poor health-related quality of life (HRQoL) have been investigated in general populations. However, these studies have examined only individual-level correlates. This study examined the association between smoking and poor HRQoL, at both the individual and contextual levels, in university settings across China. METHODS Large-scale survey sampling was conducted among 11659 health-profession students from 31 Chinese universities. HRQoL was measured by the EQ-5D instrument. This multilevel, multivariable analysis utilized unadjusted and adjusted methods. RESULTS Prevalence of poor HRQoL in this study was 2.7% (95% CI: 1.9--3.5). Multilevel logistic regression analysis revealed that frequent (OR=3.18; 95% CI: 2.35--4.33) and occasional smokers (OR=2.73; 95% CI: 1.61--4.65) and universities with high (OR=2.68; 95% CI: 1.34--5.35) and medium smoking prevalence (OR=1.49; 95% CI: 0.95--5.35) had excess odds of poor HRQoL compared to their respective referents, non-smokers and universities with a low smoking prevalence. CONCLUSIONS This multilevel study provides new evidence that smoking is associated with poor HRQL. Findings underscore the importance of alerting the populace that functional impairment is linked to smoking. [ABSTRACT FROM AUTHOR]

Background: Chronic rhinosinusitis (CRS) is defined as a condition of inflammation in the paranasal sinus mucosa persisting for more than 12 weeks. We previously reported that the prevalence of CRS was about 8 % in China. Here, we aim to investigate the occupational and environmental risk factors associated with CRS.Methods: Data were collected from seven Chinese cities: Urumqi, Changchun, Beijing, Wuhan, Chengdu, Huaian and Guangzhou. CRS was diagnosed according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EP(3)OS) document. Participants were asked to complete a standardized questionnaire, which was developed by the Global Allergy and Asthma European Network (GA(2)LEN) project and covered sociodemographic characteristics, CRS-related symptoms and occupational and environmental exposures. We evaluated the association between CRS and various occupational and environmental factors using odds ratios (ORs) and 95 % confidence intervals (95 % CIs).Results: The total study population consisted of 10,633 subjects, 850 (7.99 %) of whom were defined as having CRS according to the EP(3)OS criteria. We found that there were significant associations between occupational and environmental factors and CRS. Specifically, having a clearance-related job, occupational exposure to dust, occupational exposure to poisonous gas, a pet at home or carpet at home or at the workplace were risk factors for CRS. Additionally, the method used to keep warm in winter, the duration of time spent using air conditioning in summer and the frequency of exposure to mouldy or damp environments were significantly different in subjects with and without CRS.Conclusions: Our data showed that some occupational and environmental exposures are strongly associated with CRS, which aids in understanding the epidemiology of CRS.

Aims: To explore the association between nurse managers' paternalistic leadership and nurses' perceived workplace bullying (WPB), as well as to examine the mediating role of organizational climate in this association. Background: There is a lack of empirical evidence regarding the relationship between nurse managers' paternalistic leadership, organizational climate and nurses' perceived WPB. Clarifying this relationship is crucial to understand how paternalistic leadership influences WPB and for nursing managers to seek organizational‐level solutions to prevent it. Methods: A cross‐sectional survey was performed from 4 January to 10 February 2022, in six tertiary hospitals in mainland China. Demographic information, Paternalistic Leadership Scale, Organizational Climate Scale and Negative Acts Questionnaire‐Revised were used in the survey. Descriptive statistics, Spearman correlation analyses and a structural equation model were used for data analysis. Results: A total of 5093 valid questionnaires were collected. Moral leadership and authoritarian leadership have both direct and indirect effects on WPB through the mediating effect of organizational climate. The former is negatively related to WPB and the latter is positively related to WPB. Benevolent leadership was only negatively associated with WPB via the mediating effect of organizational climate. Conclusion: The three components of paternalistic leadership have different effects on WPB through the mediating effect of organizational climate. Nurse managers are recommended to strengthen moral leadership, balance benevolent leadership, reduce authoritarian leadership and strive to create a positive organizational climate in their efforts to mitigate WPB among nurses. Impact: This study enhanced our comprehension of the relationship between different leadership styles and WPB. Greater emphasis should be placed on moral leadership in the promotion of nursing managers and nursing leadership training programs. Additionally, nursing managers should focus on establishing a positive organizational climate that helps to reduce WPB. Patient or Public Contribution: No patient or public contribution. This study did not involve patients, service users, caregivers or members of the public. [ABSTRACT FROM AUTHOR]

Background: Trigger thumb is a prevalent hand condition observed in children, and its management remains a topic of considerable debate, ranging from mere observation to surgical intervention. In recent times, there has been a growing interest in exploring nonoperative treatments as alternatives to surgical procedures for managing pediatric trigger thumb. Gaining insight into the prevalence of spontaneous resolution in pediatric trigger thumb is of paramount importance. However, the literature presents a wide variation in estimates regarding the prevalence of this spontaneous resolution, highlighting the need for further investigation and consensus. The aim of this review was to estimate the overall prevalence of spontaneous resolution among pediatric trigger thumb. Methods: This study meticulously followed the PRISMA guidelines and registered in the PROSPERO. The PubMed, Embase, and Cochrane Library databases were searched for all relevant studies up to May 2024.Inclusion criteria were studies reported only observation spontaneous resolution pediatric trigger thumb, aged up to 14 years, reported at least 10 thumbs and followed up time at least 3 months. Confounded intervention treatment measure studies were excluded. To synthesize the prevalence rates from individual studies, we employed a random-effects meta-analysis. In order to uncover the sources of heterogeneity and to compare prevalence estimates across different groups, we performed sensitivity and subgroup analyses. To meticulously evaluate the quality of the included studies, the Joanna Briggs Institute's quality assessment checklist was employed. Furthermore, to assess the heterogeneity among the studies, both Cochran's Q test and the I² statistic were utilized. Results: A total of eleven studies were included for the final analysis, with 599 pediatric trigger thumbs. Our final meta-analysis showed that more than one-third of these pediatric trigger thumb cases resolved spontaneously, with a resolution rate of 43.5% (95% CI 29.6–58.6). Subgroup analyses showed that in terms of age at the first visit, the prevalence of spontaneous resolution in the less than 24 months group and in the 24 months or older group was 38.7%(95% CI 18.1–64.4)and 45.8%(95% CI 27.4–65.4), respectively. There was no significant difference between the two groups(P = 0.690). When analyzing follow up time, the prevalence of spontaneous resolution in the 24 months or longer group and in the less than 24 months group was 58.9%(95% CI 41.6–74.2)and 26.8%(95% CI 14.7–43.8), respectively.There was significant statistical differences between the two groups(P = 0.009). Based on the initial severity of interphalangeal (IP) joint flexion contracture, the prevalence of spontaneous resolution in the 30 degrees or less group and in the other measurements group was 54.1%(95% CI 31.5–75.1)and 37.1%(95% CI 21.9–55.4), respectively.There was no significant difference between the two groups(P = 0.259). Conclusion: Our study demonstrates that a significant proportion of pediatric trigger thumbs resolve spontaneously. This finding highlights the benefits of early observation in managing this condition. By prioritizing non-operative observation, both parents and surgeons are better equipped to make informed decisions regarding the treatment of pediatric trigger thumb, potentially reducing the need for surgical intervention.

Aims: This paper presents updated prevalence estimates of awareness, ever‐use, and current use of nicotine vaping products (NVPs) from 14 International Tobacco Control Policy Evaluation Project (ITC Project) countries that have varying regulations governing NVP sales and marketing. Design, Setting, Participants and Measurements: A cross‐sectional analysis of adult (≥ 18 years) current smokers and ex‐smokers from 14 countries participating in the ITC Project. Data from the most recent survey questionnaire for each country were included, which spanned the period 2013–17. Countries were categorized into four groups based on regulations governing NVP sales and marketing (allowable or not), and level of enforcement (strict or weak where NVPs are not permitted to be sold): (1) most restrictive policies (MRPs), not legal to be sold or marketed with strict enforcement: Australia, Brazil, Uruguay; (2) restrictive policies (RPs), not approved for sale or marketing with weak enforcement: Canada, Malaysia, Mexico, New Zealand; (3) less restrictive policies (LRPs), legal to be sold and marketed with regulations: England, the Netherlands, Republic of Korea, United States; and (4) no regulatory policies (NRPs), Bangladesh, China, Zambia. Countries were also grouped by World Bank Income Classifications. Country‐specific weighted logistic regression models estimated adjusted NVP prevalence estimates for: awareness, ever/current use, and frequency of use (daily versus non‐daily). Findings NVP awareness and use were lowest in NRP countries. Generally, ever‐ and current use of NVPs were lower in MRP countries (ever‐use = 7.1–48.9%; current use = 0.3–3.5%) relative to LRP countries (ever‐use = 38.9–66.6%; current use = 5.5–17.2%) and RP countries (ever‐use = 10.0–62.4%; current use = 1.4–15.5%). NVP use was highest among high‐income countries, followed by upper–middle‐income countries, and then by lower–middle‐income countries. Conclusions: With a few exceptions, awareness and use of nicotine vaping products varied by the strength of national regulations governing nicotine vaping product sales/marketing, and by country income. In countries with no regulatory policies, use rates were very low, suggesting that there was little availability, marketing and/or interest in nicotine vaping products in these countries where smoking populations are predominantly poorer. The higher awareness and use of nicotine vaping products in high income countries with moderately (e.g. Canada, New Zealand) and less (e.g. England, United States) restrictive policies, is likely due to the greater availability and affordability of nicotine vaping products.

Purpose Nearly 200m people in the world experience considerable functioning difficulties. Also, more than three-fourth of the population aged 50 years and over is suffering from some kind of disability in India, China, Ghana, Russia, Mexico and South Africa. Despite the compelling nature of this issue, evidence on socioeconomic disparity in the occurrence of disability is lacking throughout the world and particularly in the aforementioned countries. The purpose of this paper is twofold – first, to examine the socioeconomic inequalities in the prevalence of disability in the selected countries; and second, to investigate the cross-country differentials in the prevalence of disability by socioeconomic characteristics.Design/methodology/approach The authors use data from the Study on Global Ageing and Adult Health (SAGE) conducted in China, Ghana, India, Mexico, Russia and South Africa during 2007–2010. Disability scores have been constructed using Item Response Theory Partial Credit Model based on eight health and functioning domains. Bivariate analysis, concentration curves, concentration indices and multivariate regressions have been used in the analysis presented in this paper.Findings The authors find that the prevalence of disability varied considerably across sociodemographic groups. Moreover, this variation is not uniform across all countries. Also, age, Sex, work status, years of schooling and economic status emerged out as significant predictors of disability among the studied countries.Originality/value This is perhaps the first study which examines the socioeconomic inequality in disability conceptualized in a comprehensive manner among older adults spread across low to upper middle income countries. The alarming level of prevalence of disability among sociodemographic disadvantage groups calls for immediate attention in terms of detailed study of risk factors, effective policy and timely intervention.

Background: Klebsiella pneumoniae (KP) is the most common pathogen isolated in intensive care units (ICUs) and the most frequently encountered carbapenemase-producing Enterobacteriaceae. Increasing antimicrobial drug resistance, especially in carbapenem-resistant KP (CRKP), can limit the choice of antibiotics used for the treatment of infectious diseases and further poses a negative impact on patient outcome. However, the reason behind this increasing resistance is not well known. Patients and methods: A retrospective analysis of laboratory records and clinical cases of KP infection in the ICUs of a hospital from January 2013 to December 2017 was conducted. The disk diffusion method and double-paper synergy test were used to test drug sensitivity for extended-spectrum β-lactamase (ESBL) detection. WHONET5.6 and SPSS 21.0 software were used for statistical analysis. Results: A total of 64.8% (570/847) of patients with KP infection were older than 60 years. The lower respiratory tract was the main infection site, accounting for 70.84% (600/847); the highest rate of ICU admission was for neurosurgery, accounting for 28.69% (243/847). Some 444 multidrug-resistant KP strains were detected, including 69 CRKP and 299 ESBL-producing strains. In the past 5 years, the resistance rate of detected strains to common antibiotics increased to various degrees, particularly carbapenem-resistant strains which increased from 4.76% (9/189) in 2013 to 16.00% (28/175) in 2017. All carbapenem-resistant isolates were resistant to β-lactam antibiotics, and no isolates were resistant to tigecycline. Conclusion: CRKP and ESBLKP prevalence and resistance rates gradually increased in our ICUs in the past 5 years. The reasons for this are manifold. Regular surveillance of resistance, rational use of antibiotics, and other effective infection control measures need to be strengthened to slow down the production of multidrug-resistant bacteria and prevent their spread in ICU settings.

Background Numerous epidemiology studies on dyslipidemia have been conducted in China. However, a nationally representative estimate for dyslipidemia prevalence is lacking. The aim of this study is to appraise the nationwide prevalence, awareness, treatment, and control rates of dyslipidemia in adults in China. Methods We performed a systematic review of the related observational studies published since 2003 by searching English and Chinese literature databases. Meta-analyses were conducted in eligible studies using a random effect model to summarize the dyslipidemia prevalence, awareness, treatment, and control rates. Heterogeneity and publication bias were analyzed. Sensitivity analyses were performed to explain heterogeneity and examine the impact of study quality on the results of meta-analyses. Results Thirty-eight papers were included for meta-analyses, with a total sample size of 387,825. The prevalence, awareness, treatment, and control rates of dyslipidemia were 41.9% (95%CI: 37.7% - 46.2%), 24.4% (95%CI: 14.4% - 38.4%), 8.8% (95%CI: 7.7% - 10.0%), and 4.3% (95%CI: 4.1% - 4.5%), respectively. The prevalence of hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, low levels of high-density lipoprotein cholesterol, and high levels of low-density lipoprotein cholesterol were 10.1% (95%CI: 5.8% - 16.9%), 17.7% (95%CI: 14.0% - 22.1%), 5.1% (95%CI: 3.1% - 8.2%), 11.0% (95%CI: 8.0% - 15.0%), and 8.8% (95%CI: 4.1% - 17.8%), respectively. Sensitivity analyses revealed that males had a higher prevalence of dyslipidemia (43.2%) than females (35.6%). Study samples of age 30 and above in the eastern region tended to have higher prevalence of dyslipidemia. The quality of the studies has a slight impact on the pooled estimates. Conclusions The overall pooled prevalence of dyslipidemia in Chinese adults was estimated to be 41.9%, with males having a higher rate than females. [ABSTRACT FROM AUTHOR]

Cerebrovascular disease leads to serious disease burden because of its high morbidity, disability and mortality. In recent years, its prevalence, incidence and mortality showed a downward trend in most high-income countries but in low and middle income countries have been increasing. This paper introduced the main results from a nationwide, population-based epidemiological cross-sectional survey on cerebrovascular disease in China during the period of Twelfth Five-Year Plan for National Economic and Social Development.

Past literature has reported the ubiquitous differences in health outcomes associated with socioeconomic status across different international settings. Due to the absence of fine level aggregated data, however, rather limited studies have been conducted to explore the neighborhood social determinants of public health in developing countries, especially in China. Using district level official data in 2010, this study examines the neighborhood social determinants of three prevalent non-communicable diseases (NCDs) in Shenzhen, China. In total, 22 exploratory social variables are selected from five domains: employment, education, housing, demographic structure and income. Spatial regression in binary and stepwise form is used to recognize the most influential social determinants. Results indicate the social determinants vary with the three NCDs and they have some general similarities. Spatial binary regression identifies four principle social determinants of NCDs prevalence: employment, income, housing and demographic structure. One essential social determinant (percentage of the floating population) is identified for all the three diseases by stepwise regression. Our study highlights that the main social determinant related to the incidence rates of all NCDs is the indicator of demographic structure denoting percentage of the floating population. This paper advances the understanding of the essential social determinants of NCDs in China. [ABSTRACT FROM AUTHOR]

Background: Female sex workers (FSW) are particularly vulnerable to unintended pregnancy. Research examining the experience of unintended pregnancy due to commercial sex among Chinese FSW, however, is limited. This study aimed to examine the prevalence and correlates of unintended pregnancy due to commercial sex among FSW in China. Methods: In 2021, a cross-sectional study was conducted among 1257 FSW in five cities from Guangdong provinces in South China. Data were collected on social-demographic characteristics, sexual behaviors, experience of unintended pregnancy due to commercial sex and its pregnancy outcome, as well as experience of abortion in lifetime. Multivariable logistic regression analysis was employed to identify factors associated with unintended pregnancy. Results: Among the 1257 FSW, 19.3% reported having at least one unintended pregnancy due to commercial sex. Of those, 96.7% chose to terminate the pregnancy through induced abortion, and 40.5% reported undergoing multiple induced abortions in their lifetime. Multivariable logistic regression indicated that FSW working in current location over one year (adjusted Odds Ratio (aOR): 2.82, 95% CI 1.71–4.64) and having more than seven clients in the past week (aOR: 4.53, 95% CI 2.74–7.51) were more likely to have had unintended pregnancy due to commercial sex. Working in high tier (aOR: 0.21, 95% CI 0.14–0.30) and consistent condom use with clients in the past month (aOR: 0.16, 95% CI 0.10–0.23) were associated with a lower proportion of FSW having ever had unintended pregnancy. Conclusions: Unintended pregnancy are prevalent among FSW in South China. Interventions aimed at reducing the prevalence of unintended pregnancy and enhancing post-abortion care could be necessary among Chinese FSW. Plain English summary: Female sex workers (FSW) are particularly vulnerable to unintended pregnancies. Research on the experience of unintended pregnancy resulting from commercial sex among Chinese FSW is, however, limited. To address this knowledge gap, we investigated the prevalence and correlates of unintended pregnancies due to commercial sex among FSW in China. We conducted a cross-sectional study among 1257 FSW in five cities across Guangdong Province in South China in 2021. Multivariable logistic regression analysis was used to identify factors associated with unintended pregnancy. Among 1257 FSW, 19.3% reported having experienced at least one unintended pregnancy due to commercial sex. The factors significantly associated with unintended pregnancy in the multivariate analysis included participants working in high tier, working in current location over one year, using condom with clients inconsistently in the past month, and having more clients in the past week. The findings from this study could provide valuable insights for the development of policies aimed at reducing unintended pregnancies, improving abortion care, and enhancing family planning programs targeted at FSW.

Aim: Many people see nursing as a high‐pressure, high‐risk profession. Therefore, job burnout among nursing staff has become an important topic of study and has received widespread attention worldwide. This research intended to evaluate the frequency of and variables related with work burnout among nurses in public hospitals in China. Design: Using a multistage random sample procedure, a cross‐sectional survey was carried out in the eastern, central and western areas of China. Method s : The Maslach Inventory‐Human Service Survey and demographic information made up the two sections of the questionnaire. Of the 5250 questionnaires sent, 4865 were deemed legitimate, yielding an effective response rate of 92.67%. A linear regression analysis was performed to investigate the variables linked to nursing work burnout. Results: Among the 4865 nurses, women accounted for 97.4% of the survey respondents, most of whom were aged 26–35 years. Results showed that the total scores of emotional exhaustion (EE), depersonalization (DP) and reduced personal accomplishment (PA) were 20.02 ± 12.04, 4.78 ± 5.54 and 34.42 ± 10.32 respectively. 50.7% of subjects obtained high or moderated scores on EE, 32.8% of subjects obtained high or moderated scores on DP and 80.4% of subjects obtained low or moderated scores on PA. Age, department, position, post‐establishment, work shift type in recent months, overtime times in recent months and night shift frequency in recent months were negatively correlated with EE, and child status, monthly income, working days per week and sleep quality in recent 1 month were positively correlated with it (F = 141.827, P < 0.01, R2 = 0.243). Age, gender, department, post‐establishment, overtime hours in recent months and night shift frequency in recent months were negatively correlated with DP, and child status and sleep quality in the last 1 month were positively correlated with it (F = 78.794, p < 0.01, R2 = 0.115). Child status, years of nursing work and sleep quality in the last 1 month were negatively correlated with PA, whereas age, position, work shift type in recent months and night shift frequency in recent months were positively correlated with it (F = 67.981, p < 0.01, R2 = 0.089).

Wuhan was the first large city where the initial breakout of COVID-19 took numerous lives. A group of social workers and mental health specialists coordinated the "Be Together Program" (BTP), a psychosocial grief intervention program to help a group of Wuhan COVID-19 bereaved people. Under the Dual-process model framework, BTP used the internet and social media as the main tools, combined with group and individual intervention. Additionally, it employed a "Supermarket Mode" with abundant intervention themes and approaches for BTP participants to choose according to their special needs. Additionally, Chinese cultural elements are integrated into the program. At the end of the program, the grief scores of participants in the qualified sample reduced significantly, and the prevalence of the potential Prolonged Grief Disorder diagnosis reduced from 75% to 12%. The study also found that the BTP was especially effective for those who had high levels of grief reaction. [ABSTRACT FROM AUTHOR]

Objective: To understand the prevalence of home-related anxiety among adolescent athletes during the novel coronavirus pandemic and to ascertain the factors influencing this anxiety. Methods: We employed cluster sampling to select 1150 adolescent athletes (aged 8–18 years) from six sports training schools in Yantai City, Shandong Province. Mental health status was assessed and recorded. Chi-square tests and multivariable logistic regression were used to analyze the factors contributing to athletes' anxiety. Results: The survey revealed a COVID-19 infection rate of 38.23% (437 individuals) with an anxiety score of 40.98 ± 8.20 and an anxiety detection rate of 11.29% (129 individuals) during the COVID-19 epidemic. Female athletes exhibited a higher anxiety rate of 14.40% compared to 8.40% in male athletes. Multivariate analysis identified female gender as a risk factor for anxiety (OR = 1.64), while participation in aquatics emerged as a protective factor (OR = 0.24, 95% CI: 1.08–2.48). Professional training duration exceeding three years increased anxiety risk (OR = 3.05, 95% CI: 1.67–5.58), as did not seeking help during difficulties (OR = 2.59, 95% CI: 1.33–5.01). Interestingly, parental care was linked to increased anxiety risk (OR = 2.44, 95% CI 1.34–4.44), while care from friends was protective (OR = 0.60, 95% CI: 0.36–1.01), which was possibly due to the pressure associated with parental expectations. Conclusions: Adolescent athletes, particularly females and those with extended training durations, exhibit a heightened susceptibility to anxiety. This study also highlights that athletes who proactively seek assistance during challenging situations tend to experience lower anxiety levels. Additionally, a lack of COVID-19 infection and the involvement of concerned parents contribute to reduced anxiety among these young athletes. [ABSTRACT FROM AUTHOR]

Background: Mental health issues (depression and suicidal ideation) are increasingly common in children and emerge as escalating public health concerns. The syndemics that underline the importance of risk factor clustering provides a framework for intervention, but there is a lack of research on syndemics involving the adverse interactions of children's mental health problems. This study therefore examined the cumulative and synergistic effects of vulnerable conditions on depression and suicidal ideation among children in China. Methods: A mental health screening census of students in grades 5–12 was conducted from November 2022 to January 2023 in Nanling County, Anhui Province, China. The prevalence and co-occurrence of vulnerable conditions (unfavorable parental marital status, left-behind experience, bullying victimization, and self-harm behavior), depression, and suicidal ideation and the cumulative and synergistic effects of vulnerable conditions on depression and suicidal ideation were explored. Results: Nearly a quarter of students (24.8%) reported at least two syndemic conditions. Overall, the prevalence of depression and suicidal ideation were 20.2% and 24.2% respectively. The odds of depression and suicidal ideation were higher for children with one or more vulnerable conditions and were ten times higher for children with three or more vulnerable conditions compared with those without any vulnerable condition. These four vulnerable conditions can increase the odds of depression and suicidal ideation by interacting synergistically with each other. Conclusion: Our findings signal the importance of addressing mental health syndemics among children in China by simultaneously considering concurrent vulnerable conditions. [ABSTRACT FROM AUTHOR]

Wilson A, Gyi AA. International Journal of Nursing Practice 2010; 16: 92–98 The status and perspective of diabetes health education in China: Inspiration from Australia This paper discusses possible approaches to improving diabetes care and developing effective education models in China based on the experience of diabetes education in Australia. The prevalence of diabetes mellitus in China is increasing rapidly. China is currently second on the list of the top 10 countries with the highest diabetes burden. Enormous impact of diabetes on China health system is daunting and the urgent action is needed. Diabetes education is the keystone of diabetes care and structured self-management education is considered to be the key to successful outcomes. Although many diabetes education programmes have been initiated in China, barriers have been identified for implementation of the programmes. These include: lack of public awareness of diabetes; lack of standards of practice for diabetes educators; and lack of evaluation programmes to assess their performance. We suggest four possible approaches to addressing the current problems of diabetes education in China. [ABSTRACT FROM AUTHOR]

INTRODUCTION A number of studies have reported a high correlation between psoriasis and metabolic syndrome (MetS), and tobacco smoking is one independent risk factor accounting for the increased prevalence both for psoriasis and MetS. However, few studies have been conducted to assess the effects of tobacco smoking on co-morbidities of psoriasis and MetS. METHODS We conducted a cross-sectional study with 1014 psoriasis patients recruited from January to May 2021. Patients were recruited with a cluster survey method in Yueyang Hospital (affiliated with Shanghai University of Traditional Chinese Medicine) and Shanghai Skin Diseases Hospital (affiliated with Tongji University). Data were collected by face-to-face questionnaire interviews which included basic information, personal life habits, medical history, and clinical examinations. SPSS 24.0 was used for data analysis and a p<0.05 was considered statistically significant. RESULTS The 1014 psoriasis patients were predominantly males (65.58%), with an average age of 45.98 years (IQR: 34.00--57.00). Of these, 25.74% (261) of psoriasis had MetS and 31.85% (323) were tobacco smokers. Male psoriasis patients had higher tobacco smoking prevalence than female patients. With increasing age and BMI, the prevalence of tobacco smoking among psoriasis patients increased dramatically (p<0.01). Logistic regression indicated that psoriasis patients with tobacco smoking had 1.78 times (95% CI: 1.21--2.60) the probability to have MetS than those without tobacco smoking, even adjusting for potential confounding factors. Moreover, smoking psoriasis patients with MetS consumed more cigarettes per day, with longer smoking duration, but with an older age of smoking initiation. CONCLUSIONS The prevalence of tobacco smoking and MetS among psoriasis patients was high in Shanghai, and tobacco smoking was positively associated with the MetS among psoriasis patients. Clinicians should recommend psoriasis patients to abstain from tobacco smoking and provide tobacco cessation assistance regularly. [ABSTRACT FROM AUTHOR]

Background: Understanding the past-year prevalence of male-perpetrated intimate partner violence (IPV) and risk factors is essential for building evidence-based prevention and monitoring progress to Sustainable Development Goal (SDG) 5.2, but so far, population-based research on this remains very limited. The objective of this study is to compare the population prevalence rates of past-year male-perpetrated IPV and nonpartner rape from women's and men's reports across 4 countries in Asia and the Pacific. A further objective is to describe the risk factors associated with women's experience of past-year physical or sexual IPV from women's reports and factors driving women's past-year experience of partner violence.Methods and Findings: This paper presents findings from the United Nations Multi-country Study on Men and Violence in Asia and the Pacific. In the course of this study, in population-based cross-sectional surveys, 5,206 men and 3,106 women aged 18-49 years were interviewed from 4 countries: Cambodia, China, Papua New Guinea (PNG), and Sri Lanka. To measure risk factors, we use logistic regression and structural equation modelling to show pathways and mediators. The analysis was not based on a written plan, and following a reviewer's comments, some material was moved to supplementary files and the regression was performed without variable elimination. Men reported more lifetime perpetration of IPV (physical or sexual IPV range 32.5%-80%) than women did experience (physical or sexual IPV range 27.5%-67.4%), but women's reports of past-year experience (physical or sexual IPV range 8.2%-32.1%) were not very clearly different from men's (physical or sexual IPV range 10.1%-34.0%). Women reported much more emotional/economic abuse (past-year ranges 1.4%-5.7% for men and 4.1%-27.7% for women). Reports of nonpartner rape were similar for men (range 0.8%-1.9% in the past year) and women (range 0.4%-2.3% in past year), except in Bougainville, where they were higher for men (11.7% versus 5.7%). The risk factor modelling shows 4 groups of variables to be important in experience of past-year sexual and/or physical IPV: (1) poverty, (2) all childhood trauma, (3) quarrelling and women's limited control in relationships, and (4) partner factors (substance abuse, unemployment, and infidelity). The population attributable fraction (PAF) was largest for quarrelling often, but the second greatest PAF was for the group related to exposure to violence in childhood. The relationship control variable group had the third highest PAF, followed by other partner factors. Currently married women were also more at risk. In the structural model, a resilience pathway showed less poverty, higher education, and more gender-equitable ideas were connected and conveyed protection from IPV. These are all amenable risk factors. This research was cross-sectional, so we cannot be sure of the temporal sequence of exposure, but the outcome being a past-year measure to some extent mitigates this problem.Conclusions: Past-year IPV indicators based on women's reported experience that were developed to track SDG 5 are probably reasonably reliable but will not always give the same prevalence as may be reported by men. Report validity requires further research. Interviews with men to track past-year nonpartner rape perpetration are feasible and important. The findings suggest a range of factors are associated with past-year physical and/or sexual IPV exposure; of particular interest is the resilience pathway suggested by the structural model, which is highly amenable to intervention and explains why combining economic empowerment of women and gender empowerment/relationship skills training has been successful. This study provides additional rationale for scaling up violence prevention interventions that combine economic and gender empowerment/relationship skills building of women, as well as the value of investing in girls' education with a view to long-term violence reduction.

In this paper, we examine patterns of self-reported diagnosis of noncommunicable diseases (NCDs) and prevalences of algorithm/measured test-based, undiagnosed, and untreated NCDs in China, Ghana, India, Mexico, Russia, and South Africa. Nationally representative samples of older adults aged ≥50 years were analyzed from wave 1 of the World Health Organization's Study on Global Ageing and Adult Health (2007-2010; n = 34,149). Analyses focused on 6 conditions: angina, arthritis, asthma, chronic lung disease, depression, and hypertension. Outcomes for these NCDs were: 1) self-reported disease, 2) algorithm/measured test-based disease, 3) undiagnosed disease, and 4) untreated disease. Algorithm/measured test-based prevalence of NCDs was much higher than self-reported prevalence in all 6 countries, indicating underestimation of NCD prevalence in low- and middle-income countries. Undiagnosed prevalence of NCDs was highest for hypertension, ranging from 19.7% (95% confidence interval (CI): 18.1, 21.3) in India to 49.6% (95% CI: 46.2, 53.0) in South Africa. The proportion untreated among all diseases was highest for depression, ranging from 69.5% (95% CI: 57.1, 81.9) in South Africa to 93.2% (95% CI: 90.1, 95.7) in India. Higher levels of education and wealth significantly reduced the odds of an undiagnosed condition and untreated morbidity. A high prevalence of undiagnosed NCDs and an even higher proportion of untreated NCDs highlights the inadequacies in diagnosis and management of NCDs in local health-care systems.

Background: Tobacco control in China, the world's largest producer and consumer of tobacco, began in the 1980s with the first national prevalence survey and a conference on tobacco held in Tianjin. Since then, there have been dozens of research papers, partial restrictions on smoking and tobacco advertising, public education campaigns, and the ratification of the World Health Organization Framework Convention on Tobacco Control, but progress has been slow. The state-owned tobacco industry remains a major obstacle to tobacco control. Recent developments: In the last few years, tobacco control efforts have accelerated beyond expectations. The triggering event was the publication on tobacco by the Chinese Central Party School, the ideological think tank of the Communist Party, followed by a spate of activity: directives to government officials; regulations issued by the Ministry of Education, the People's Liberation Army and the Healthy City Standards; tobacco clauses in national advertising and philanthropy laws; the creation of a Smoke-free Beijing; an increase in tobacco taxation; and a national smoke-free law currently in draft. Areas timely for policy research and action: There is a crucial need for China to build upon these recent developments, in accepting the economic research evidence of the debit of tobacco to the economy; in implementing robust, comprehensive legislation; in increasing cigarette price through taxation and, most challenging of all, to tackle the power and influence of the state tobacco monopoly over tobacco control.

The China Mental Health Survey (CMHS) is the first nationally representative community survey on mental disorders and mental health services in China. One-step diagnoses for mood disorders, anxiety disorders and substance use disorders were obtained using the Composite International Diagnostic Interview-3.0 (CIDI-3.0), according to the criteria and definition of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). A two-step procedure was applied for schizophrenia and other psychotic disorders, using psychosis screening section in CIDI-3.0 as a screening instrument and the Structured Clinical Interview for DSM-IV Axis I disorders (SCID) as a diagnostic tool. Dementia was diagnosed by the 10/66 dementia diagnosis package in a two-step design. The main aims of the CMHS were: (1) to investigate the prevalence of mood disorders, anxiety disorders, substance use disorders, schizophrenia and other psychotic disorders, and dementia; (2) to obtain data of service use of individuals with mental disorders in China; and (3) to analyse the social and psychological risk factors or correlates of mental disorders and mental health services. This paper presents a brief review of the background of the CMHS, its aims and measures. [ABSTRACT FROM AUTHOR]

Background: To identify independent factors of cognitive frailty (CF) and construct a nomogram to predict cognitive frailty risk in patients with lung cancer receiving drug therapy. Methods: In this cross‐sectional study, patients with lung cancer undergoing drug therapy from October 2022 to July 2023 were enrolled. The data collected includes general demographic characteristics, clinical data characteristics and assessment of tools for cognitive frailty and other factors. Logistic regression was harnessed to determine the influencing factors, R software was used to establish a nomogram model to predict the risk of cognitive frailty. The enhanced bootstrap method was employed for internal verification of the model. The performance of the nomogram was evaluated by using calibration curves, the area under the receiver operating characteristic curve, and decision curve analysis. Results: A total of 372 patients were recruited, with a cognitive frailty prevalence of 56.2%. Age, education background, diabetes mellitus, insomnia, sarcopenia, and nutrition status were identified as independent factors. Then, a nomogram model was constructed and patients were classified into high‐ and low‐risk groups with a cutoff value of 0.552. The internal validation results revealed good concordance, calibration and discrimination. The decision curve analysis presented prominent clinical utility. Conclusions: The prevalence of cognitive frailty was higher in lung cancer patients receiving drug therapy. The nomogram could identify the risk of cognitive frailty intuitively and simply in patients with lung cancer, so as to provide references for early screening and intervention for cognitive frailty at the early phases of drug treatment.

Background: Within China, Hepatitis B virus (HBV) infection remains widely prevalent and one of the major public health problems. There have been only two previous estimates of its prevalence at the population level in China, with the latest survey conducted in 2006. A meta-analysis estimated the prevalence of HBV within China between 2013 and 2017 as 7%. This review provides an updated estimate of HBV prevalence in China from 2018 to 2022. Methods: Systematic searches of literature from January 1, 2018 to December 25, 2022 were conducted in four international databases (Medline, Web of Science, Embase, Cochrane Database of Systematic Reviews) and three Chinese databases (CNKI, CBM, and WanFang data). Random-effects meta-analyses were conducted to calculate the pooled HBV prevalence with 95% confidence intervals in the overall population and subgroups. Publication bias, heterogeneity between studies, and study quality were assessed. Results: Twenty-five articles were included in the meta-analysis. The pooled prevalence of HBV infection in the Chinese general population from 2018 to 2022 was 3% (95%CI: 2–4%). The prevalence of HBV infection was similar between males and females (both 3%), while rural areas had a higher prevalence than urban areas (3% vs 2%). The highest prevalence of HBV was reported in the eastern provinces (4, 95%CI: 2–6%). The HBV prevalence of people aged ≥18 years old (6, 95%CI: 4–8%) was higher than people aged < 18 years old (0, 95%CI: 0–1%). Conclusion: Compared to the previous meta-analysis prevalence in 2013–2017, the updated meta-analysis estimated prevalence of HBV infection (3%) from 2018 to 2020 showed a decreasing trend, suggesting China had moved into a lower intermediate epidemic area (2–5%). However, the prevalence of HBV in rural areas and eastern regions was still higher than the national average. People aged ≥18 years old showed a higher HBV prevalence. HBV prevention should be prioritized in the highest-prevalence areas and high-risk populations. Due to heterogeneity in data collection methods among studies, there remains a need for systematic surveillance of nationwide HBV prevalence. [ABSTRACT FROM AUTHOR]

Background: Dementia has become one of the leading causes of death across the world. Aims: The aim of this study was to investigate the incidence, prevalence, and mortality of dementia in China between 2010 and 2020, and to investigate any geographical, age, and sex differences in the prevalence and incidence of dementia. Methods: Five databases were searched. The Joanna Briggs Institute (JBI) critical appraisal tool was used to assess the quality of the included studies. A random-effects meta-analysis was performed to estimate the pooled prevalence of dementia. Subgroup analysis was based on the type of dementia. The incidence and mortality of dementia were synthesized qualitatively. Results: A total of 19 studies were included. The meta-analysis showed that the prevalence of dementia was 6% (95%CI 5%, 8%), the prevalence of Alzheimer's disease (AD) was 5% (95%CI 4%, 6%), and the prevalence of vascular dementia (VaD) was 1% (95%CI 0%, 2%). The subgroup analysis showed that the prevalence rates of dementia in rural (6%, 95%CI 4%, 8%) and urban areas were similar (6%, 95%CI 4%, 8%). Deaths due to dementia increased over time. Conclusion: The prevalence, incidence, and mortality of dementia increased with age and over time. Applying consistent criteria to the diagnosis of cognitive impairment and dementia is necessary to help with disease monitoring. Promoting dementia knowledge and awareness at the community level is necessary. [ABSTRACT FROM AUTHOR]

The article examines the number of physicians in China who have died from sudden death due in part to overwork, violence, and professional pressure to publish scientific papers.

Background: Multiple sclerosis (MS) is a rare chronically debilitating disease. There are few reports on the burden of disease of MS and prevalence in China. The authors intended to estimate disease burden and prevalence of MS in Shandong Province using available epidemiologic data.Methods: Prevalence was calculated using DISMOD II software based on incidence extrapolated from hospitalization data, case fatality and remission rate from literature as input indexes. Disability-adjusted life year (DALY) was computed with epidemiologic indexes estimated by DISMOD II program.Results: The prevalence of MS was estimated to be 3.7(95 % CI: 1.65-5.8) and 6.7(95 % CI: 2.7-9.56) cases per 100,000 people for males and for females, respectively. The mean age at onset of MS was 36.0(43.0 ± 30.0 years in males and 33.7(43.4 ± 29.7) years in females. Duration of the disease was estimated to be 34.0 (31.6 ± 21.0) years for males and 39.5(34.9 ± 21.8) years for females. The disease burden in disability-adjusted life years was 3316, comprised of 903 (27.2 %) years of life lost (YLL) and 2413 (72.8 %) years lived with disability (YLD).Conclusions: Our study highlighted that population in Shandong Province had a high prevalence of MS and the patients had a heavy disease burden. It also revealed that the results obtained in this paper would be useful to provide a reference for establishing specific healthcare policies for this rare disease in Shandong Province.

The aim of this study is to identify the prevalence of cardiovascular disease (CVD) and major CVD risk factors, including diabetes, hypertension, dyslipidemia, obesity and smoking among Chinese immigrants by a systematic review of studies from various countries. PubMed and the China National Knowledge Infrastructure databases were searched for studies of the prevalence of major CVDs and risk factors, and of CVD mortality among Chinese immigrants. The search identified 386 papers, 16 of which met the inclusion criteria for this review. In mainland China, there is a pattern of high stroke prevalence but low coronary heart disease (CHD) prevalence. Among Chinese immigrants, there is a much lower prevalence and mortality of stroke, but a higher prevalence and mortality of CHD, even though these are lower than the rates in immigrants of other ethnicities in the host country. The prevalence of CVD risk factors is also markedly different in immigrants. Compared with mainland Chinese, Chinese immigrants have a higher prevalence of diabetes and hypertension, higher serum cholesterol, poorer dietary patterns, and higher prevalence of obesity and smoking. Thus, the epidemiological pattern of CVD among Chinese immigrants changes compared with resident mainland Chinese. The less healthy environmental factor after immigration may be a major trigger in the adverse CVD status of Chinese immigrants. It is important for policy-makers to pay more attention to specific minority immigrant groups, and to implement more effective preventive measures to improve the health of immigrant populations.

Objective: Little is known about the nationwide cancer prevalence in China. This paper aimed at assessing the 5-year cancer prevalence in China for 25 major cancers.Materials and Methods: Incidence data were estimated using data from 177 cancer registries and covering 175 million populations. Survival data were from 17 cancer registries diagnosed during 2003-2005 and followed up until 31 December 2010. Standardized protocols for data collection and validation were adopted. Cancer prevalence for 25 major sites was estimated from year-specific incidence rates and survival probabilities according to standardized formula.Results: The estimated 5-year prevalence for all cancers combined in 2011 in China was 7.49 million (3.68 million for men and 3.81 million for women). Cancer prevalence estimates for 5 years varied by cancer sites, ranging from 11,900 for testicular cancer to 1.02 million for women breast cancer. Those most prevalent five cancers (breast, colorectal, lung, stomach and esophageal cancers) covered 56.1% of cancer burden in China. The proportion for the 5-year prevalence was higher in urban areas compared to rural areas (666 per 100,000 versus 440 per 100,000), while cancer prevalence estimates were higher for women compared to men, with the men/women ratio of 5-year cancer prevalence reaching 0.96.Conclusions: This paper provides the first systematic analysis on 5-year cancer prevalence for 25 major cancers in China in 2011, which may serve as a baseline for assessment of the overall effectiveness of cancer health care. The huge number of cancer survivors requires resource allocation to improve health care programs and primary prevention, especially in rural areas. [ABSTRACT FROM AUTHOR]
