Sedentary behavior (SB) is prevalent in workplaces, putting office workers at an increased risk of severe health problems. To help designers and researchers gain a better understanding of office workers’ contextual concerns for physical inactivity (reducing SB and enhancing physical activity (PA)), we have proposed a conceptual framework ACTIVE4. This framework advises designers and researchers to consider four key factors that influence office workers’ physical inactivity: active mind, active behavior, active support, and active environment. We conducted three workshops (N=28 design students) to evaluate the framework. The participants found ACTIVE4 helpful in guiding them towards a more systematic understanding of the environmental influences and office workers’ personal needs for reducing physical inactivity. In future work, we will optimize the ACTIVE4 framework’s learning curve as suggested by participants and conduct an expert study to further discuss design opportunities and requirements for the ACTIVE4-related vitality toolkit.

Today, under the conditions where the number of office workers and artificial lighting applications have increased, although the effects of the Photometric Flicker phenomenon are serious, it is an issue that has not been understood in detail and people are not aware of it. Photometric Flicker phenomenon, which is a direct result of using ballasts or drivers with low power factor and lacking the necessary filtering features; It causes results such as decreased visual performance, loss of attention and perception. Considering that the conversion of LED luminaires is still not completed in many office buildings in the country, it is seen as an important requirement to investigate the Flicker effect in interior spaces that are considered to offer similar lighting levels and conditions, and to make a concrete due diligence by correlating this with the average age of office workers. For this reason, in this study, various tests and experiments were carried out with volunteer participants aged 18-30, 31-45 and 46 years of age and older without any significant vision problems, and the outputs of these studies were aimed to shed light on the relationship between age and lighting conditions. Keywords: Photometric Flicker, Interior lighting, Age and lighting relationship, Disruptive effects in lighting

Objectives: In this study, we gave information about appropriate working position to the office workers who have low back pain for last 3 months and we aimed to determine the effect of this intervention on frequency and level of low back pain and functionality of the workers. Materials and Methods: This study was an interventional study. Data were collected in September 2017 and December 2017 using face to face interview method. Information was given by a one-hour conference and distributing 4 informative brochures between October 2017 and November 2017. Results: 409 persons participated in the study and 141 of them who had low back pain for last 3 months formed the intervention group. 59.7% of the participants noted that they usually perform desk work. Logistic regression analysis showed that low back pain was 3,25 times more frequent among women than men, and 2,41 times more frequent among workers who had non-communicable disease. Among workers who had low back pain and attended the conference and read at least one brochure, mean Visual Analog Scale score was 5,97±1,2 before intervention and 5,03±1,1 after intervention (p0,05). Conclusions: Considering the effect of intervention, this result shows that implementation of intervention with health promotion approach at workplace is an appropriate method for reducing severity of low back pain and increasing functionality.

Background. The vaccine is the best available instrument to prevent influenza and reduce the risks of major disease complications and mortality. The vaccine effectiveness during the influenza season depends on a number of factors: (1) a person vaccinated (their age and health status); (2) the vaccine formulation; (3) types and subtypes of the circulating viruses; (4) vaccination timeline, as the immune response fades over time. An influenza vaccine can yield different effectiveness in people who have been infected or vaccinated previously and in those who have not been yet exposed to the circulating viruses. At present, trivalent and quadrivalent influenza vaccines are registered and produced in Russia. It allows for vaccination of all social groups, including high-risk populations, and for increasing the number of vaccinated individuals yearly. Russian Federation constantly improves the production of influenza vaccines, introducing new variants of vaccine formulations into national clinical usage. It is thus essential to monitor and analyze the changes in the effectiveness of influenza vaccines every season.Aim of the study. To evaluate of the effectiveness of Russian domestic influenza vaccines during the epidemic season 2019–2020 in St. Petersburg compared to the season 2018–2019.Materials and Methods. 3315 female and male adult participants aged 18 years and older were monitored from October 2019 to March 2020. The group included university students and tutors, researchers, and production and office workers of industrial enterprises. Sovigripp, Grippol Plus, Ultrix, and Ultrix Quadri influenza vaccines were used for immunization.Results and Discussion. In the context of incomplete correspondence between the viruses circulating in Russia and the strains used in the vaccines, the vaccination of the St. Petersburg population during the epidemic season 2019-2020 with Sovigripp, Grippol Plus, Ultrix, and Ultrix Quadri influenza vaccines cumulatively reduced influenza and ARI incidences by half; the total vaccine effectiveness against influenza and ARI amounted to 50.0%. The strongest preventive effect was identified for Grippol Plus, Ultrix, and Ultrix Quadri which demonstrated the total vaccine effectiveness from 70.6% to 75.0%, and their effectiveness against influenza A and B viruses reached from 65.5% to 83.5%.Conclusion. In the context of incomplete correspondence between the viral strains used in the vaccines and the strains circulating in Russia and St. Petersburg during the epidemic season 2019- 2020 and considering the active circulation of non-influenza viruses such as rhinoviruses and adenoviruses, we found a moderate preventive effectiveness of the influenza vaccines during the seasonal epidemic increase in ARI cases. Russian domestic influenza vaccines were shown to have good acceptability, be safe, and non-reactogenic.

PURPOSE Noise is one of the major environmental health problems and is defined as any unpleasant sound. It was shown that prolonged exposure to noise was associated with progress of diseases. There is no study evaluating the effect of noise on the oxidative parameters of Total Antioxidant Capacity (TAC), Total Oxidant Status (TOS) and DNA damage. AIM This study aimed to evaluate the effect of noise on TOS, TAC and DNA damage. METHODS In this study, we included 100 textile factory workers affected by noise as a noise group, and 56 healthy volunteers employed as office workers in our hospital who were not exposed to noise as the control group. Blood samples were obtained from both the groups. Oxidative Stress (OS) was measured by Oxidative stress index (OSI), TOS and TAC. The DNA damage level was measured by 8-Hydroxydeoxyguanosine (8-OHdG). RESULTS 8-OHdG (21.8 ± 12.0 vs. 14.7 ± 5.6 pg/ml, p = 0.001),TOS (14.1 ± 2.5 vs. 10.9 ± 1.5 mol H2O2 equivalent/l, p

Introduction. According to Russian and foreign studies, the frequency of musculoskeletal system pathology continues to grow. To improve the life quality and reduce the level of the musculoskeletal system diseases, an urgent task is to increase the volume of available non-drug methods of prophylaxis.The aim of the research was to develop measures to prevent the formation of somatic dysfunctions of the musculoskeletal system and their relapses in office workers using osteopathic correction.Materials and methods. In the period from 2016 to 2020, a prospective controlled randomized study was carried out on the basis of the ANO TIMM. The work is based on the results of osteopathic care in combination with a controlled change in the ergonomics of the workplace after the correction of somatic dysfunctions of the musculoskeletal system in office workers. The study involved 426 people who were divided into two comparable groups: the main and control groups of 212 and 214 people, respectively. All patients underwent osteopathic diagnostics before the start of the treatment, during therapy, and at its completion in accordance with the approved clinical guidelines. Patients of both groups received osteopathic care provided in accordance with the developed algorithm. The patients of the main group underwent correction of their workplaces ergonomics.Results. The study showed that office workers are characterized by the presence of somatic dysfunctions at the regional and local levels. Somatic dysfunctions of the spine, pelvis, abdominal and pelvic diaphragms were most often observed. As a result of osteopathic correction in combination with a change in the ergonomics of the workplace in patients of the main group, the frequency of recurrences of the somatic dysfunctions formation decreased significantly (pConclusion. The use of osteopathic correction in combination with the workplace ergonomics change effectively contributes to the prevention of the formation of the musculoskeletal system somatic dysfunctions and their recurrence in office workers.

The purpose of this study is to verify the triple mediating effect of appearance satisfaction, body image, and hope in the relationship between appearance management behavior and happiness in 234 adults working in highway rest areas nationwide. Data analysis was performed using SPSS PC+ 25.0 and SPSS PROCESS macro3.5, and triple mediating effect analysis was performed using frequency analysis, reliability analysis, correlation analysis, and bootstrap analysis: This study was conducted to verify the triple mediating effect of appearance satisfaction, body image and hope in the relationship between appearance management behavior and happiness. The conclusions of the study are as follows. First, in the correlation analysis between the major variables, there were mostly significant positive correlations between appearance management behavior, appearance satisfaction, body image, hope, and happiness, but there was no correlation between body image and happiness or appearance satisfaction and happiness. Second, appearance management behavior had a significant positive effect on appearance satisfaction, appearance satisfaction had a significant positive effect on body image, body image had a significant positive effect on hope, and hope had a significant positive effect on happiness. Thus, appearance satisfaction, body image, and hope had a triple mediating effect in the relationship between appearance management behavior and happiness. As described above, few studies have dealt with this precise issue, and the discussion of these relationships needs to be expanded. Our results imply that improving one's appearance through various behaviors in order to appear more beautiful to others leads to changes in appearance and increased satisfaction with appearance. Thus, appearance management behavior not only changes one's appearance, but also results in positive psychological changes. In the end, such changes may promote happiness. The results of this study can be used as a new model for happiness improvement through appearance management behavior in office workers.

A research was conducted among the employees referred to work in the home office in connection with the announced state of the epidemic in Poland. The research was conducted using a questionnaire method, the study was attended by 199 respondents. The research is burdened with an error in the selection of statistical sample units, which resulted from the respondents’ involvement and their truthfulness. The aim of the article is to assess the activities of employers from the private and state sectors in Poland, related to the delegation of employees to work in the home office, and to analyze the skills and possibilities of self-organization of work by employees. An important result of the survey was to demonstrate the differences in the behavior of public and private sector employers. The study shows that the private sector has adapted better to sudden changes than the state sector.

Objective To investigate the interrelationships among concerns regarding dental visits, the status of regular dental visits, and periodontal health during the coronavirus disease 2019 (COVID‐19) pandemic. Background Continuous oral health care and regular dental visits are important for maintaining periodontal health. Due to the possibility of contracting COVID‐19, individuals have been reluctant to visit medical institutions. It is unclear how the periodontal health of the Japanese population has been affected by the interruption of regular dental visits during the COVID‐19 pandemic and how concerns regarding dental visits have affected attendance at regular dental visits. Methods This study included 199 Japanese office workers in one municipal office at Fukuoka Prefecture, Japan (average age = 42.6 years; age range = 19–77 years; 123 men and 76 women). Periodontitis was defined based on a full‐mouth periodontal examination. The status of regular dental visits during the COVID‐19 pandemic and concerns regarding dental visits were obtained via questionnaire. We tested the hypothesis that concerns regarding dental visits would indirectly affect periodontal health through the interruption of regular dental visits during the COVID‐19 pandemic. We used mediation analysis, in which concerns regarding dental visits (present or absent) were set as the exposure, periodontitis (present or absent) was set as the outcome, and the status of regular dental visits (continued during the COVID‐19 pandemic or not) was set as the mediator. Results Of the 199 study participants, 108 had a habit of attending regular dental visits. Of these, 31 (28.7%) discontinued regular dental visits during the COVID‐19 pandemic. Compared to the individuals who continued regular dental visits, those who discontinued regular dental visits had a higher prevalence of periodontitis (49.4% vs 77.4%, p

BACKGROUND: COVID-19 lockdown caused a sudden change in the work culture and environment. OBJECTIVE: The aim of this study was to evaluate the impact of COVID-19 lockdown caused changes in musculoskeletal pain (MSP), physical activity (PA), workplace properties, and their in-between relationships among office workers. METHODS: A total of 161 office workers (64.6%female) with a mean age of 38.2±9.5 years participated. The study was conducted as an online form. Baecke Physical Activity Questionnaire, NORDIC Questionnaire, and questions about the work environment were used. The participants were asked to describe the current situation and retrospectively the situation 3 months before. RESULTS: We found no significant differences in the prevalence of MSP or between the mean number of body regions suffering from MSP before and during the lockdown. During the lockdown, a significant (p

The relationship between occupational exposure and different skin diseases including scalp psoriasis and Pityriasis amiantacea has been studied. The information about imbalance of essential trace elements in psoriatic patients is still scarce. In the present follow-up study, the scalp hair and blood samples of patients (labors of cement factory) have different skin disorders (plaque's psoriasis and Pityriasis amiantacea) and were analyzed for zinc (Zn) and selenium (Se) before and after treatment with mineral supplements. For comparative purposes, both biological samples of referents who do not have any skin disease (office workers and labors of cement industry) were also analyzed for Zn and Se using an atomic absorption spectrometer. The result indicates a significant decrease in the concentrations of Se and Zn in both biological samples of patients with scalp psoriasis and P. amiantacea as compared with referents/controls, whereas the referent labor has not any skin disease with 15-25% lower values of both essential trace elements as compared to office worker, possibly due to poor diet.

BACKGROUND: Computer workstation use is a risk factor for the development of musculoskeletal disorders. Governmental guidelines have been developed as a resource for workstation set-up to minimize this risk. The degree of worksite compliance with guidelines has not been examined. OBJECTIVE: The purpose of this study was to examine workstations using the VDT Workstation Checklist to determine compliance, and potential modifications. METHODS: Subjects were recruited from a variety of work settings in Erie, PA. Workstations were assessed with the worker present, using the VDT Workstation Checklist. Adjustments and recommendations were made as appropriate. RESULTS: Of the 60 workstations examined, 48%did not receive a passing score. All but one were correctable to an acceptable level with minimal low-cost modifications. The recommendation for wrist rests (43%), changes in monitor height (30%) or position (27%) and reposition of the keyboard (13.3%) and mouse (13.3%) were the most frequent modifications. Ten (16.7%) workstations did not require modification. CONCLUSIONS: Almost half of workstations reviewed were not in compliance with current guidelines, however almost all (98%) could be brought into compliance with simple modifications. Office workers need guidance in setting up workspace and adjusting ergonomic equipment to provide comfortable and safe work settings and minimize musculoskeletal symptoms.

Background There are limited studies on the health effects of street trading in spite of common knowledge that individuals engaged in the trade are exposed to high levels of traffic-related air pollution per their mode of operation, and also the fact that the venture is a dominant occupation in cities of Sub-Saharan Africa (SSA) and other developing regions. Objective We characterized particulate matter (PM) pollution levels at traffic hotspots of Accra, Ghana during the dry and wet seasons, and assessed exposure experiences of street traders. Methods A cross-sectional study was conducted among 236 street traders operating along six selected traffic routes of Accra and a comparison group of 186 office workers. PurpleAir PA-II monitors were used to measure PM levels at the selected traffic routes. We estimated annual PM2.5 exposure of street traders using assigned seasonal PM2.5 levels, and information collected in a structured questionnaire on their activity patterns. Outcomes investigated were self-reported respiratory and cardiovascular symptoms. Results PM levels at Accra traffic hotspots were high in both seasons. 1 ug/m3 increase in PM2.5 exposure increased respiratory, cardiovascular, and overall symptoms by a factor of 0.00027 (95% CI: 0.00012, 0.00041), 0.00022 (95% CI: 0.00007, 0.00036), and 0.00048 (95% CI: 0.00023, 0.00073), respectively. Compared to office workers, high PM2.5 exposure among street traders was associated with increased odds of coughing, catarrh (postnasal drip), sneezing, rapid heart beating, irregular heartbeat, sharp chest pains, fainting spells, headaches, and dizziness. Low and medium PM2.5 exposure was associated with increased odds of dermatitis, rapid heart beating, and irregular heartbeat, and sharp chest pains, respectively. Conclusions We found consistent evidence that PM2.5 exposure among street traders increases the occurrence of respiratory and cardiovascular symptoms. We also provide indicative measurements of PM levels at traffic hotspots of a rapidly growing SSA city with heavy vehicular traffic and yet, limited air quality monitoring capacity.

Purpose: The purpose of this study was to investigate the effect of the application of spinal support device with core stabilization exercise on the pain and low back dysfunction of office workers with non-specific low back pain (NSLBP). Methods: This study was conducted with 50 office workers with NSLBP. Participants were randomly assigned to the intervention and control groups. Both groups performed core stabilization exercise and bed rest for three times a week for 4 weeks, and the intervention group used a spinal support device for bed rest. The primary outcome was pain, and the secondary outcome was low back dysfunction and satisfaction. Measurements were performed pre and post intervention. Results: As a result of the study, the intervention group showed a significant improvement in resting pain, working pain, pain pressure threshold (PPT), and low back dysfunction (p

Background: Sedentary behavior is one of the leading modifiable risk factors for cardiovascular disease and all-cause mortality. Physical exercise exerts beneficial physiological effects on cardiovascular fitness. Different grades of physical exercise have different effects on cardiovascular health. Objective: To compare the effect of moderate and high intensity exercise training on heart rate variability (HRV) in sedentary office workers. Methods: This study was conducted on 40 healthy sedentary volunteers aged between 20-40 years of both the genders. Participants were distributed into two groups of 20 subjects each. Subjects of group I and group II performed moderate intensity and high intensity exercise respectively on bicycle ergometer for 12 weeks. Their 5- minute ECG recording was done by three channel physiograph, and frequency domain indices of HRV and heart rate (HR) were analyzed and compared before and after exercise training. Their blood pressure was also recorded and compared before and after exercise training. Independent sample t-test and paired sample ttest were used for statistical analysis. Results: HF, systolic and diastolic blood pressure reduced significantly after exercise in group II (p=0.015, 0.005, and 0.015 respectively) while HR and LF/HF ratio reduced in both group I and group II (p=0.000 for HR, and 0.034, 0.001 for LF/HF). The decrease in HR was greater after high intensity exercise than moderate intensity exercise (p= 0.025). Conclusion: Parasympathetic activity improves after moderate and high intensity exercise but improvement is more after high intensity exercise training. Therefore, high intensity exercise training is more beneficial than moderate intensity exercise training. J Bngladesh Soc Physiol 2021;16(1): 16-23

Hairdressers may be differentially exposed to phthalates through hair salon services provided and products used, yet no U.S. studies have investigated these exposures in this population. We characterized concentrations and exposure determinants to nine phthalate metabolites in postshift urine samples among 23 hairdressers from three Black and three Dominican salons, as well as a comparison group of 17 female office workers from the Maryland/Washington D.C. metropolitan area. Overall, hairdressers had higher metabolite concentrations than office workers. The geometric mean (GM) for monoethyl phthalate (MEP) was 10 times higher in hairdressers (161.4 ng/mL) than office workers (15.3 ng/mL). Hairdressers providing select services and using certain products had higher GM MEP concentrations than those who did not: permanent waves/texturizing (200.2 vs 115.4 ng/mL), chemical straightening/relaxing (181.6 vs 92.1 ng/mL), bleaching (182.3 vs 71.6 ng/mL), permanent hair color (171.9 vs 83.2 ng/mL), and Brazilian blowout/keratin treatments (181.4 vs 134.6 ng/mL). Interestingly, hairdressers providing natural services had lower GM MEP concentrations than those who did not: twists (129.1 vs 215.8 ng/mL), sister locs/locs (86.0 vs 241.9 ng/mL), and afros (94.7 vs 203.9 ng/mL). Larger studies are warranted to confirm our findings and identify disparities in occupational phthalate exposures.

Sick building syndrome is a group of symptoms relatively common among office workers; such symptoms could have an impact on the worker's productivity. The aim of this research is to provide a better understanding of the relation between design elements, indoor environmental quality and sick building syndrome within office spaces in Cairo, Egypt. Results show that a healthy environment leads to higher level of office productivity. Several design elements were chosen to be analysed according to previous studies, and their relation to the indoor environmental quality was noted. The prevalence of these elements on sick building syndrome was studied. An empirical comparative study has been conducted within two administrative office buildings at Cairo campus of the ‘Arab Academy for Science Technology & Maritime Transport' in Egypt. Data collection was done by a self-administrated questionnaire. The questionnaire includes personal background, work design elements, socio-demographic elements and symptoms of sick building syndrome. Headache and fatigue were the most prevalent symptoms in both buildings. This study revealed that office comfort is the most important factor affecting office occupants and should be taken seriously when designing office spaces for better working environment free of sick building syndrome.

Objectives. This study aimed to define specific patterns of multisite musculoskeletal disorders (MSDs) in office employees and to examine how derived patterns relate to ergonomic chair design. Methods. This cross-sectional study of 254 office employees extracted major patterns of MSDs using latent class analysis and investigated the association with ergonomic chair design. Results. Four major patterns of MSDs were extracted using latent class analysis: class 1 (12.1%), individuals with high probabilities of MSDs in the neck, shoulders, back and wrists; class 2 (35.6%), individuals with near-zero probabilities of MSDs across all sites; class 3 (14.1%), those with high probabilities of complaints in the back, hips and knees; class 4 (38.2%), those with high probabilities of MSDs across all sites. Considering class 2 as the reference, there was an inverse significant association between seat comfort and membership in class 3 (odds ratio [OR] 0.94, 95% confidence interval [CI] [0.89, 0.99]) and class 4 OR 0.94, 95% CI [0.91, 0.98], and a significant inverse relationship between body support and membership in class 4 OR 0.95, 95% CI [0.92, 0.99]. Conclusion. MSDs can be summarized with latent class-derived patterns among office workers. Ergonomic chair design was significantly associated with type of MSD patterns.

Neck pain found to be most common musculoskeletal condition in office workers with 12-month prevalence. Mechanical neck pain can be classified into two categories in clinical studies mechanical neck pain which has patients without any identifiable anatomic cause and leaves patients having neurological dysfunctions cervicogenic headache and inflammatory disorders. Current research work has total of 150 participants out of which there were 100 females school teachers having mean age of 37.8 years(median 38 years) and 50 male school teachers having mean age 40 years (median 39 years). Participants included in the study were professionally active school teachers of primary, secondary and senior secondary. Scapula position and neck disability was examined as per keiblers lateral scapular slide test and Neck disability index. Total 150 teachers were included in the study 80 teachers having mechanical neck pain (study group) and 70 teachers not having mechanical neck pain (control group) statistically significant difference found in scapula position and neck disability. In the present research, it is found that there is statistically significant difference in scapula position protraction and upward rotation at three different levels as well as there are statistically significant changes observed in neck disability.

Musculoskeletal disorders (MSDs) are a global problem. In Indonesia, the prevalence of MSDs that disrupts activities reaches 9.2% in office workers with complaints of the neck by 68%, upper back 62%, and lower back 60%. In developing countries, MSDs are the most common occupational diseases found in 40-95% of lecturers. In 2020, the COVID-19 pandemic in Indonesia resulted in the government implementing work from home (WFH) which caused 66.3% of workers to experience musculoskeletal pain. This can be caused by not fulfilling sleep which is a physiological need. It was found that 41.9% of adults experienced sleep disturbances which affected the emergence of MSDs complaints. This study aimed to determine the relationship between sleep quality and musculoskeletal complaints. This is an analytical study using a cross-sectional design towards the lecturers and educational staff at the Faculty of Medicine Universitas Pembangunan Nasional Veteran Jakarta. A sample size of 84 people was taken using the purposive sampling technique. Data were collected online using the PSQI for sleep quality and NMQ for musculoskeletal. The data were analyzed using SPSS software.The results showed that the majority of respondents were female (54.8%), had poor sleep quality (94%), and experienced musculoskeletal complaints (73.8%). The results of the Fisher test showed a significant relationship between sleep quality and musculoskeletal complaints (p = 0.016; OR = 13.5). Conclusion: The low quality of sleep in lecturers and educational staff increase the risk of developing musculoskeletal disorders.

The prevalence of metabolic syndrome in workers is high. Its impact can lower health status and disrupt work productivity. This research aimed to identify the dominant factor of metabolic syndrome among workers in government agencies of the Tanjung Priok port, Jakarta. The research method used descriptive- analytic with a cross-sectional design. The study used secondary data from medical check-up records of 256 workers in Port of Tanjung Priok. The inclusion criteria was all employees who had a medical check-up. Exclusion criteria was pregnancy and individuals with too much missing or poorly recorded information. The chi-square test and binary logistic regression were applied for analysis. The study found that metabolic syndrome prevalence was quite high in workers (38.7%). The results of a multivariate analysis showed physical activity (p = 0,003, OR = 2,238), total energy (P = 0,038, OR = 1,960), and carbohydrate intake (p = 0,014, OR = 0,490), together became the risk factor of the metabolic syndrome among workers. The dominant factor of metabolic syndrome was physical activity. The worker was susceptible to low physical activity so that the risk of metabolic syndrome was quite high. The company should improve the health promotion program in the workplace with regular screening, improved physical activity and provide a healthy meal to prevent metabolic syndrome in workers.

As an important component of bike-sharing (BS) users, the travel behavior of college students and office workers is important to the promotion of BS within Chinese cities. To explore the influencing factors for the behavioral intentions of BS, this paper makes a different analysis between the two groups. Based on the theory of planned behavior, and using environmental awareness as an extended variable, a BS travel intention model was developed. A total of 676 valid questionnaires were collected and analyzed from college students and office workers in Zhengzhou. The results indicate that attitude, subjective norms, perceived behavior control, and environmental awareness have a positive impact on the behavioral intentions of BS. However, the influence degree of each variable is different between the two groups. Perceived behavior control, including travel time, travel cost, and cycling difficulty, has the greatest impact on BS behavioral intention for college students. Meanwhile, subjective norms, including policy and media publicity, has the most significant impact on BS behavioral intention for office workers. The impact of environmental awareness on college students’ use of BS is higher than that of office workers. We also found that undergraduates use BS more frequently than postgraduates. The findings provide the clear influence factors on behavioral intentions of BS between college students and office workers, that can help policy optimization in terms of bike-sharing systems, giving some suggestion for an approach devoted to deepen the individual-context interactions

목적: 본 연구에서는 만성 두통을 앓고 있는 직장인들을 대상으로 SNPE 다나손을 이용한 C-move 운동이 두통감소에 미치는 영향을 양적연구와 질적연구의 통합을 통해 살펴보았다. 방법: 순서균형화를 적용한 반복측정실험 설계를 통해 5일 동안 SNPE 다나손 C-move 운동과 목 스트레칭을 각각 수행하였고, 사전/사후에 걸쳐 VAS, NDI, HIT-6을 측정하였다. 실험 종료 7일 후, 질적자료를 수집하기 위해 대상자들과 심층 인터뷰를 진행하였다. 결과: 다나손을 적용한 C-move 운동을 목 스트레칭과 비교한 결과 다나손이 스트레칭 보다 통증감소와 통증관련 증상을 약화시키는데 도움이 되는 것으로 나타났다. 질적연구에서도 대상자들은 다나손이 통증 개선에 대해 긍정적 경험을 하는 것으로 도출되었다. 결론: SNPE 다나손을 이용한 C-move 운동은 두통과 경추장애를 완화하는데 도움이 되었고, 스트레칭보다 두통완화에 효과적이라고 볼 수 있다.

BACKGROUND: Musculoskeletal disorders are of multi-factorial origin, including individual, physical, and psychosocial factors. An effective education program for musculoskeletal disorders should include predisposing factors. OBJECTIVE: This study aimed to examine the effect of risk factor education on pain intensity and disability levels compared to a home-based exercise program in office workers with nonspecific neck or low back pain. METHODS: A pilot cluster randomized clinical trial was conducted in 46 workers with neck or low back pain. The education group received checklists of risk factors and handbooks providing information on how to manage them. The exercise group received a home-based exercise program to manage their neck or low back pain. The primary outcome measures were pain intensity and disability levels. RESULTS: There was no significant difference in pain intensity or disability level between groups at baseline and follow-ups. However, neck and low back pain intensity, but not disability level, at the 3-month and 6-month follow-ups was significantly lower than those at baseline in both groups. CONCLUSION: Risk factor education was not more effective than the home-based exercise program in terms of pain intensity or disability reduction in workers with nonspecific neck or low back pain.

ObjectivesSedentary behaviour among office workers and the risk of adverse health outcomes are public health problems. However, risk indicators for these outcomes require invasive biochemical examination. A proactive screening tool using a non-invasive, easy-to-use method is required to assess the risk focused on musculoskeletal health for primary prevention. However, middle-aged adults have insufficient awareness of musculoskeletal disorders. This study examined to determine whether the 30-s chair-stand test (CS-30) can be used as a proactive screening index for musculoskeletal disorder risk of sedentary behaviour in office workers.DesignCross-sectional study using self-administered questionnaires and physical measurements.SettingFour workplaces located in a metropolitan area of Japan.Participants431 Japanese office workers aged 20–64 years. 406 valid sets of results remained (valid response rate: 94.2%).Primary and secondary outcome measuresMusculoskeletal function was measured using the CS-30, quadriceps muscle strength. Receiver operating characteristic curve analysis was used to determine the sensitivity, specificity and optimal cut-off value for the CS-30. The risk of future incidence of musculoskeletal disorders was calculated using current quadriceps muscle strength.ResultsIn total participants, 47.0% were male and the mean sitting time in work duration was 455.6 min/day (SD=111.2 min). The mean lower limb quadriceps muscle strength was 444.8 N (SD=131.3 N). For the optimum cut-off value of 23 on the CS-30 for all participants, sensitivity was 0.809 and specificity was 0.231. For men, the optimum cut-off was 25, with a sensitivity of 0.855 and a specificity 0.172. For women, the optimum cut-off was 21, with a sensitivity of 0.854 and a specificity 0.275.ConclusionsSensitivity was high, but specificity was insufficient. The CS-30 may be a potential proactive screening index for musculoskeletal disorder risk of sedentary behaviour, in combination with other indicators.

Accurate measurement of time spent sitting, standing, and stepping is important in studies seeking to evaluate interventions to reduce sedentary behavior. In this study, the authors evaluated the agreement in classification of these activities from three algorithms applied to thigh-worn ActiGraph accelerometers using predictions from the widely used activPAL device as a criterion. Participants (n = 29, 72% female, age 23–68 years) wore the activPAL3™ micro (processed by PAL software, version 7.2.32) and the ActiGraph™ GT9X accelerometer on the right front thigh concurrently for working hours on one full workday (7.2 ± 1.2 hr). ActiGraph output was classified via the three test algorithms: ActiGraph’s ActiLife software (inclinometer); an open source method; and, a machine-learning algorithm reported in the literature (Acti4). Performance at an instance level was evaluated by computing classification accuracy (F scores) for 15-s windows. The F scores showed high accuracy relative to the criterion for identifying sitting (96.7–97.1) and were 84.7–85.1 for identifying standing and 78.1–80.6 for identifying stepping. The four methods agreed strongly in total time spent sitting, standing, and stepping, with intraclass correlation coefficients of .96 (95% confidence interval [.92, .96]), .92 (95% confidence interval [.81, .96]), and .87 (95% confidence interval [.53, .95]) but sometimes overestimated sitting time and underestimated standing time relative to activPAL. These algorithms for identifying sitting, standing, and stepping from thigh-worn accelerometers provide estimates that are very similar to those obtained using the activPAL.

This study assessed musculoskeletal complaints (MSCs) in administrative workers, associating MSCs with nonpaid housework, home use of electronic devices and physical exercise, while keeping a distinctive gender approach. This may promote the development of more effective preventive measures, by meeting the specific strengths and weaknesses of each gender. Methods. Ninety-six administrative workers (58 women and 38 men) who used computers more than 50% of their working time participated in a cross-sectional study. A questionnaire concerning individual socio-demographic data, habits and lifestyle, and including the Nordic musculoskeletal questionnaire (NMQ), was deployed. Gender-based odds ratios for MSCs in body areas over the previous 12 months and correlation coefficients between habits and lifestyle variables and NMQ variables were computed. Results. Women did not incur a higher risk of MSCs than men. Analysis of the association did not yield meaningful associations for either gender. Results suggest giving future consideration to development of gender-specific preventive measures. Conclusion. Computerized work performed concomitantly with physical exposures outside the workplace showed mixed associations with MSCs, according to gender and depending on the kind of exposure. Results are indicative of the need for development of gender-specific preventive measures., Fundação para a Ciência e Tecnologia (FCT) and C-MAST – Centre for Mechanical and Aerospace Science and Technologies.

The prevalence of dry eye syndrome (DES) has rapidly increased in recent years, negatively affecting the eye health of many office workers worldwide. Although low eye blink rate (EBR) has been pointed out as one of the main risk factors for DES, it is difficult for office workers to continuously monitor and increase their own involuntary blinking, especially when they are focused on the primary work task. Thus, as an effort to help office workers correct their low EBR, the current study developed a real-time EBR level classification system utilizing sitting postural behavior data. A total of twenty participants performed typical computer tasks on a sensor-embedded chair. The participants’ eye blinking and postural behavior data were collected to develop the EBR level classification system with a random forest algorithm. After evaluating the system performance, the relationships between EBR and postural behaviors were empirically examined to help understand how the system worked for EBR level classification. As a result, the developed system showed high classification performance overall; and compared with high EBR condition, low EBR condition was related to less overall postural variability and greater extent of forward bending posture. The real-time EBR level classification system is expected to contribute to preventing/relieving DES and thereby enhancing the eye health of office workers.
