Introduction: Limited information is available on the association between depressive symptoms and waist circumference (WC) in individuals with normal weight. This study aimed to analyze the association between depressive symptoms and WC among individuals aged 18 years or older with normal weight in the Peruvian population between 2019 and 2021., Methods: Analytical cross-sectional study. Data from the Peruvian Demographic and Health Survey (2019-2021) were analyzed. The sample consisted of 26 933 participants. The outcome variable was WC. The exposure variables included the overall Patient Health Questionnaire-9 (PHQ-9) score and severity of depressive symptoms. Generalized linear models of the Gaussian family estimated the effects with β coefficients for the associations between WC and depressive symptoms stratified by age and sex., Results: A significant inverse association was observed between depressive symptoms and WC in young (< 35 years) individuals of both sexes. In young males, a dose-response relationship emerged, with greater severity of depressive symptoms associated with progressively lower WC. Specifically, inverse associations were found for moderate (β = -1.74, 95% CI: -3.25 to -0.23), moderately severe (β = -2.81, 95% CI: -4.71 to -0.91), and severe (β = -2.75, 95% CI: -5.11 to -0.40) depressive symptoms., Conclusions: Among young individuals of both sexes with a normal weight, depressive symptoms were inversely associated with WC. These findings underscore the need for nuanced considerations of age and sex when exploring the interplay of depression and abdominal adiposity in individuals with normal weight., (© 2024 Wiley Periodicals LLC.)

Objectives. The improvised and massive adoption of remote work in the context of COVID-19 has forced us to adapt homes as workspaces, which could promote development of musculoskeletal disorders (MSDs). This review explores the evidence for ergonomic factors associated with MSDs in teleworkers. Methods . A literature search was conducted in MEDLINE, Embase, Scopus, SciELO and EBSCO. We included observational studies published between March 2020 and October 2021 that included teleworking personnel due to the restrictions of the pandemic. Results . A total of 212 studies were identified, 14 were chosen for complete review. Associated factors were change of work modality (on-site work to telework), use of home environments as workspaces (areas not adapted for work and with low lighting), working furniture (non-ergonomic chairs and desks), use of electronic devices (tablets, cell phones and laptops), organizational factors (working hours, active breaks, sitting time) and individual factors (physical activity practice). Conclusion . Various ergonomic home factors and the characteristics of teleworking - mainly furniture, the environment of work and physical activity - are associated with MSDs. This evidence suggests that the norms and regulation of telework can consider the adaptation of workspace and conditions at home to prevent health problems in the medium and long term.

Objective: Few studies, using countrywide data, examined how hypertension prevalence varies at diverse degrees of urbanization and altitude. This study examined the association between urbanization and altitude, including the potential interaction between those variables, with hypertension prevalence in Peru., Methods: Cross-sectional analysis of the Peruvian Demographic and Health Survey (2014-2019). Hypertension (SBP ≥140 mmHg or DBP ≥90 mmHg or self-reported diagnosis) was the outcome. Exposures were altitude levels, and urbanization assessed with four indicators (urban/rural; type of place of residence; population density level; and population size level)., Results: Among 186 906 participants (mean age ± standard deviation: 40.6 ± 17.9; 51.1% women), pooled hypertension prevalence was 19% [95% confidence interval (CI) 18.7-19.3], which was higher in urban compared with rural areas (prevalence ratio: 1.09; 95% CI 1.05-1.15). Compared with countryside, hypertension was higher in towns (prevalence ratio: 1.09; 95% CI 1.04-1.15), small cities (prevalence ratio: 1.07; 95% CI 1.02-1.13) and large cities (prevalence ratio: 1.19; 95% CI 1.12-1.27). Compared with least density settings (1-500 inhabitants/km 2 ), hypertension was higher in the highest density (≥10 001 inhabitants/km 2 ) settings (prevalence ratio: 1.12; 95% CI 1.07-1.18). Population size was not associated with hypertension. Compared with low altitude, hypertension was lower above 2500 m (prevalence ratio 0.91; 95% CI 0.87-0.94) and above 3500 m (prevalence ratio 0.89; 95% CI 0.84-0.95). Interaction between exposures had varying patterning., Conclusion: Hypertension in Peru is more prevalent at urban than rural areas, especially in large cities and in more densely populated areas above 10 001 inhabitants/km 2 , and less prevalent at altitudes above 2500 m., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: During 2021, Peru started the vaccination against SARS-CoV-2 using the BBIBP-CorV inactivated virus vaccine for health care workers (HCW). We aim to evaluate the effectiveness of the BBIBP-CorV vaccine to prevent SARS-CoV-2 infection and deaths among HCWs., Methods: Retrospective cohort study, from February 9 to June 30, 2021, using national registries of health care workers, laboratory tests for SARS-CoV-2 and deaths. We calculated the vaccine effectiveness for preventing laboratory-confirmed SARS-CoV-2 infection, COVID-19-mortality, and all-cause mortality among partially immunized and fully immunized HCWs. An extension of Cox proportional hazards regression was used to model the mortality results, and Poisson regression was used to model SARS-CoV-2 infection., Results: The study included 606,772 eligible HCWs, the mean age was 40 (IQR: 33.0, 51.0). In fully immunized HCW, the effectiveness for preventing all-cause mortality was 83.6 (95% CI: 80.2 to 86.4), 88.7 (95% CI: 85.1 to 91.4) for preventing COVID-19 mortality, and 40.3 (95% CI 38.9 to 41.6) for preventing SARS-CoV-2 infection., Conclusion: The BBIBP-CorV vaccine showed high levels of effectiveness for preventing all-cause and COVID-19 deaths among fully immunized HCW. These results were consistent within different subgroups and sensitivity analyses. However, the effectiveness for preventing infection was suboptimal in this particular setting., Competing Interests: Declaration of competing interest We declare no competing interests., (Copyright © 2023.

Background: Telementoring seems to be a promising strategy to deliver training and counselling to physicians in remote areas. In Peru, early graduated physicians must work for the Rural and Urban-Edge Health Service Program where they face important training needs. The aim of this study was to describe the usage of a one-on-one telementoring program for rural physicians and evaluate the aspects related to the perceptions of acceptability and usability., Methods: Mixed methods study on recently graduated physicians who work in rural areas and participate in the telementoring program. The program used a mobile application to connect these young doctors with specialized mentors to answer queries about real-life problems raised by working in a rural area. We summarize administrative data to assess participant characteristics and their participation in the program. Additionally, we conducted in-depth interviews to explore the perceived usability, ease of use, and reason for non-use of the telementoring program., Results: Of 74 physicians (mean age 25, 51.4% women) enrolled, 12 (16.2%) actively used the program and performed a total of 27 queries, which received response in an average time of 5.4 ± 6.3 h. In the interviews, the main reasons for non-use were connectivity issues, feelings of shame, and self-efficacy. For those who used the telementoring program they referred it was easy to use and solve their inquiries timely., Conclusions: The implementation of a telementoring program sought to provide guidance to recently graduated physicians working in rural areas. Low use rates show that administrative and process-related deficiencies in the program implementation need to be improved., (© 2023. The Author(s).)

Front-of-package warning labels (WLs) are among the public health policies adopted by some countries, mainly in Latin-America, to tackle childhood obesity; however, their impact is still under review. The aim of this study was to assess, using an experimental design, whether WLs influence purchase intention of processed foods and identification of the healthiest products among adolescents in Peru, in May 2019, just before WLs mandatory implementation. Four hundred forty-nine adolescents from two public schools were randomly assigned to an experimental group (received three different processed products with either zero, one or two WLs, informing if they were high in sugar, sodium and/or saturated fats) or a control group (received the same products but unlabeled). Participants chose which product they would buy, and which they considered to be the healthiest. No differences between groups were found neither in purchase intention ( p = 0.386) nor in the identification of the healthiest product ( p = 0.322). In both groups, the most-selected product was always the healthiest of the triad (>40% in purchase intention and >80% in identification of the healthiest). Front-of-package WLs did not influence purchase intention, or identification of healthier products among adolescents from public schools in Peru. Mass media and educational campaigns should accompany the WLs implementation to help achieve the policy objective.

Objective: To identify gaps in national stroke guidelines that could be bridged to enhance the quality of stroke care services in low- and middle-income countries., Methods: We systematically searched medical databases and websites of medical societies and contacted international organizations. Country-specific guidelines on care and control of stroke in any language published from 2010 to 2020 were eligible for inclusion. We reviewed each included guideline for coverage of four key components of stroke services (surveillance, prevention, acute care and rehabilitation). We also assessed compliance with the eight Institute of Medicine standards for clinical practice guidelines, the ease of implementation of guidelines and plans for dissemination to target audiences., Findings: We reviewed 108 eligible guidelines from 47 countries, including four low-income, 24 middle-income and 19 high-income countries. Globally, fewer of the guidelines covered primary stroke prevention compared with other components of care, with none recommending surveillance. Guidelines on stroke in low- and middle-income countries fell short of the required standards for guideline development; breadth of target audience; coverage of the four components of stroke services; and adaptation to socioeconomic context. Fewer low- and middle-income country guidelines demonstrated transparency than those from high-income countries. Less than a quarter of guidelines encompassed detailed implementation plans and socioeconomic considerations., Conclusion: Guidelines on stroke in low- and middle-income countries need to be developed in conjunction with a wider category of health-care providers and stakeholders, with a full spectrum of translatable, context-appropriate interventions., ((c) 2021 The authors; licensee World Health Organization.)

Objective: To describe and compare attitudes, lifestyle behaviors, and cardiometabolic risk factors between individuals with and without a relative with type 2 diabetes mellitus (T2DM) living in the same household., Methods: A secondary analysis of baseline data from an implementation study in Peru was conducted. The outcomes were attitudes towards changing lifestyle behaviors (e.g. intentions towards losing weight, increasing physical activity, reducing salt consumption, etc), profiles of health lifestyle behaviors (e.g. daily smoking, heavy drinking, and physical activity), and cardiometabolic risk factors (e.g., overweight [body mass index ≥25 kg/m 2 ] and hypertension); whereas the exposure was the presence of at least one relative with known diagnosis of T2DM living in the same household. Multilevel logistic mixed effect regression models were used to estimate odds ratios (OR) and 95% confidence intervals (95% CI)., Results: A total of 2298 records, 1134 (49.4%) males, mean age 43.3 (SD: 17.2) years, were analyzed. There was no evidence of a difference in lifestyle-changing attitudes, smoking, alcohol drinking, physical activity levels, and hypertension between individuals with and without relatives with T2DM. Overweight was 63% more common among individuals having a relative with a T2DM in multivariable model (OR = 1.63; 95% CI: 1.03-2.61)., Conclusions: Individuals with relatives with T2DM have higher probabilities of being overweight compared to those who did not have relatives with T2DM in the same household. The absence of differences on lifestyle-related attitudes and behaviors highlight the need of involving relatives of patients with T2DM on intervention strategies to further enhance diabetes prevention and management efforts., (Copyright © 2020 Primary Care Diabetes Europe.

People with disabilities (PWD) face several challenges accessing medical services. However, the extent to which architectural and transportation barriers impede access to healthcare is unknown. In Peru, despite laws requiring that buildings be accessible for PWD, no report confirms that medical facilities comply with such regulations. Thus, we aim to provide an association between these barriers and access to medical facilities. Data from a Peruvian disability survey were analyzed. Participants were 18 years of age and older people who reported having a physical disability. Accessibility was defined by reported struggles accessing medical facilities (health or rehabilitation centers). Absence of ramps, handrails, elevators, adapted bathrooms, and information counters in medical facilities were reported as architectural barriers. The transportation barriers analyzed included struggles using buses or trains. Poisson regression models with robust variance were used to estimate prevalence ratios (PR) and to control for confounding variables. 20,663 participants were included, their mean age was 66.5 years and 57.5% were females. Architectural and transportation barriers reported were 40% and 61%, respectively. All barriers reported were more prevalent in rural compared to urban areas (p < 0.001). Inadequacy of ramps, handrails, and adapted elevators and bathrooms were associated with limited use of rehabilitation centers (p < 0.001) but not of health centers (p > 0.05). Architectural and transportation barriers represent a hindrance to seeking treatment at rehabilitation centers. Actions to improve this situation are needed.

Background: Unmanned aircraft vehicles (UAVs) have had a rapid escalation in manageability and affordability, which can be exploited in healthcare. We conducted a systematic review examining the use of drones for health-related purposes., Methods: A search was conducted in Medline, Embase, Global Health, Scopus, CINAHL and SciELO. Experimental studies were selected if the population included human subjects, the intervention was the use of UAVs and there was a health-related outcome., Results: Of 500 results, five met inclusion criteria during an initial search. An updated search yielded four additional studies. Nine studies, all in high-income countries, were included for systematic syntheses: four studies addressed out-of-hospital cardiac arrest emergencies, three assessed drones for identification of people after accidents, one used drones to transport blood samples and one used drones to improve surgical procedures in war zones., Conclusions: Research on the use of drones in healthcare is limited to simulation scenarios, and this review did not retrieve any studies from low- and middle-income countries.

Background: Previous studies have shown that hypertension is a risk factor for cognitive impairment, but whether this association is also present in extremely poor populations in Low Middle Income Countries settings remains to be studied. Understanding other drivers of cognitive impairment in this unique population also merits attention., Methods: We performed a secondary analysis using data from the "Encuesta de Salud y Bienestar del Adulto Mayor", a regional survey conducted in an extremely poor population of people older than 65 years old from 12 Peruvian cities in 2012. The outcome variable was cognitive impairment, determined by a score of ≤7 in the modified Mini-Mental State Examination. The exposure was self-reported hypertension status. Variables such as age, gender, controlled hypertension, education level, occupation, depression and area of living (rural/urban) were included in the adjusted analysis. We used Poisson regression with robust variance to calculate prevalence ratios (PR) and 95% confidence interval (95% CI) adjusting for confounders., Results: Data from 3842 participants was analyzed, 51.8% were older than 70 years, and 45.6% were females. The prevalence of cognitive impairment was 1.7% (95% CI 1.3%-2.1%). There was no significant difference on the prevalence of cognitive impairment between the group of individuals with hypertension in comparison with those without hypertension (PR = 0.64, 95% CI 0.33-1.23)., Conclusions: The association described between hypertension and cognitive impairment was not found in a sample of extremely poor Peruvian older adults.

Introduction: Use of sunscreen is encouraged to reduce the risk of skin pathologies caused by radiation. It is important to acknowledge the associated factors that promote or hinder sunscreen use in young populations as to design better prevention policies., Objective: To determine the factors associated with regular sunscreen use among first year medical students from a Peruvian university., Materials and Methods: A cross-sectional study was performed. Our population was first-year medical students from a Peruvian university. We administrated an electronic survey to evaluate socio-demographic data, as well as student knowledge, attitudes, and practices regarding photo-protection. We used ordinal logistic regression to analyze the factors associated with sunscreen use., Results: Of 420 first-year students, 299 completed our survey. We found that 53.5% of the participants were less than 18 years old, 63.2% were female, 9.3% (females more than males) responded that a sunburn was worth it to look tan, and 38.1% always or almost always used sunscreen during the summer. Factors associated with sunscreen use in the ordered logistic adjusted regression were male sex (OR = 0.50, IC95% = 0.34-0.86), participation in photo-protection workshops within the last year (OR = 2.40, IC95% = 1.28-4.37), and having somebody to remind them the use of sunscreen during the last three months (OR = 3.80, IC95% = 1.28-11.20)., Conclusions: In our sample, a higher sunscreen use was more often observed among female participants, those who attended skin protection workshops, and those reminded to use sunscreen. This highlights the importance of educational and reminder activities in the adoption of protective habits, such as sunscreen use.

Human capital requires opportunities to develop and capacity to overcome challenges, together with an enabling environment that fosters critical and disruptive innovation. Exploring such features is necessary to establish the foundation of solid long-term partnerships. In this paper we describe the experience of the CRONICAS Centre of Excellence in Chronic Diseases, based at Universidad Peruana Cayetano Heredia in Lima, Peru, as a case study for fostering meaningful and sustainable partnerships for international collaborative research. The CRONICAS Centre of Excellence in Chronic Diseases was established in 2009 with the following Mission: "We support the development of young researchers and collaboration with national and international institutions. Our motivation is to improve population's health through high quality research." The Centre's identity is embedded in its core values - generosity, innovation, integrity, and quality- and its trajectory is a result of various interactions between multiple individuals, collaborators, teams, and institutions, which together with the challenges confronted, enables us to make an objective assessment of the partnership we would like to pursue, nurture and support. We do not intend to provide a single example of a successful partnership, but in contrast, to highlight what can be translated into opportunities to be faced by research groups based in low- and middle-income countries, and how these encounters can provide a strong platform for fruitful and sustainable partnerships. In defiant contexts, partnerships require to be nurtured and sustained. Acknowledging that all partnerships are not and should not be the same, we also need to learn from the evolution of such relationships, its key successes, hurdles and failures to contribute to the promotion of a culture of global solidarity where mutual goals, mutual gains, as well as mutual responsibilities are the norm. In so doing, we will all contribute to instil a new culture where expectations, roles and interactions among individuals and their teams are horizontal, the true nature of partnerships.
