    Abstract Objective: To assess the performance of a simple correction method for nutritional status estimates in children under five years of age when exact age is not available from the data.
    Materials and methods: The proposed method was based on the assumption of symmetry of age distributions within a given month of age and validated in a large population-based survey sample of Mexican preschool children.
    Results: The main distributional assumption was consistent with the data. All prevalence estimates derived from the correction method showed no statistically significant bias. In contrast, failing to correct attained age resulted in an underestimation of stunting in general and an overestimation of overweight or obesity among the youngest.
    Conclusions: The proposed method performed remarkably well in terms of bias correction of estimates and could be easily applied in situations in which either birth or interview dates are not available from the data.

    Title translation Occupational health and safety: educational intervention for cleaning workers in research sectors.
    Abstract Objective: To evaluate the results of educational interven- tion on health and safety regarding principles of biosafety in cleaning workers of a health institution.
    Materials and methods: Using concurrent mixed methods, we evaluated a total of 31 workers on their knowledge, attitudes, and practices of biosafety and risk perception. We conducted baseline measurements and two follow-ups. Fractional logistic regression models were fitted with study stage as covariate. Additional models included interactions of study stage with key workers characteristics. Thematic qualitative analysis and triangulation was developed.
    Results: The knowledge (+33.3 points, scale 0-100), attitudes (+10.6), and practices (+23.5) increased significantly in the first follow-up; knowledge de- creased in the second follow-up (p<0.001). The qualitative findings revealed an improvement in risk prevention attitudes and practices, framed by experiences of vulnerability, stigma, and discrimination.
    Conclusions: The study provides key elements for biosafety research related to vulnerable groups and it is effective in promoting the health of a disadvantaged and invisible sector.

    Abstract Objective: To study the association between density of stores (food and beverage stores, stores selling only fruits and vegetables, and supermarkets) and the BMI of adults aged ≥20 years in Mexico.
    Design: A cross-sectional study was performed. Individual data came from the 2012 National Health and Nutrition Survey, while information on stores was taken from the National Institute of Geography and Statistics' National Statistics Directory of Economic Units. A weighted least-squares model was estimated to test the association between density of stores and BMI of adults adjusting for sex, age, education, presence of hypertension, diabetes or both, household assets index and marginality index at the municipality level.
    Setting: Mexico.
    Results: An additional 1 sd in the density of fruit and vegetable stores was associated with a reduction of 0·24 (95 % CI -0·37, -0·12) kg/m2 in BMI when the densities of the other stores were at their mean values. For food and beverage store density, a difference of 1 sd was associated with an increase of 0·50 (95 % CI 0·33, 0·67) kg/m2 in BMI, while for supermarkets the corresponding association was a reduction of 0·48 (95 % CI -1·52, 0·56) kg/m2 in BMI.
    Conclusions: In places with a higher density of stores that offer unhealthy foods, the BMI of adults tends to be higher.

    Abstract Background: Although the associations between specific socioeconomic status (SES) indicators and overweight or obesity (OWOB) have been studied in different countries, fewer evidence exists for these associations when multiple SES indicators are considered simultaneously. Furthermore, there are few studies investigating time trends in OWOB and their relation with SES in upper-middle income countries, especially for men. The present study contributes to a better understanding of the nature and evolution of the associations between SES indicators and OWOB in the Mexican adult population.
    Methods: We pooled data from the 2006 and 2012 National Health and Nutrition Surveys in Mexico and obtained covariate-adjusted prevalence from a design-based logistic multiple regression model. Covariates included a wealth index, education, occupational status, marital status, and all interactions for each covariate with sex (male/female) and survey year.
    Results: For men, the association between wealth and OWOB remained positive in general but curvature was more evident in 2012. The wealth-OWOB association in women showed an inverted-U pattern at both years with a positive slope that turned into a negative one as wealth increased. Among women, OWOB prevalence at the college/university education level was approximately 12.0 ± 2.4 (percentage points ± standard error) lower compared with the elementary education level. We did not find differences between educational categories for men in 2006, but in 2012 OWOB tended to be higher among the more educated. The prevalence of obesity in women increased at wealth levels from the middle and upper-middle section of the wealth distributions. Overall OWOB prevalence was near 70 % in 2012 for both sexes.
    Conclusions: Among Mexican women, the associations between SES indicators and excess body weight were consistent to those found in developed countries. Among Mexican men, higher education was not associated with a lower prevalence of OWOB but the positive association between wealth and OWOB weakened as wealth increased. The overall prevalence of OWOB was very high for both sexes; its reduction should remain a public health priority given the consequences of nutrition-related chronic diseases, disability and health care costs.

    Abstract Providing evidence on mental disorders in indigenous adolescents is critical to achieving universal health coverage (UHC). The prevalence of symptoms of depression and generalized anxiety disorder symptoms were estimated for 2082 adolescents aged 14-20 years in Chiapas, Mexico. Mental disorders were assessed using the 9-item Patient-Health Questionnaire and the 7-item Generalized Anxiety Disorder Scale. Among the adolescents evaluated, 35.8% suffered from depression or generalized anxiety disorder. Of those, 6.1% reported a previous diagnosis. 32.1% of adolescents with both mental disorders reported having attempted suicide. Gender, substance use, adverse living experiences and living conditions were correlated to the presence of depression and/or generalized anxiety disorder. It is mandatory for Mexican health authorities to develop effective instruments aiming to screen and diagnose mental health conditions in adolescents, as well as to provide timely treatment in primary health-care units.

    Abstract BACKGROUND: Depression is a foremost cause of morbidity throughout the world and the prevalence of depression in women is about twice as high as men. Additionally, overweight and obesity are major global health concerns. We explored the relationship between depression and body fat, and the role of physical activity and diet as mediators of this relationship in a sample of 456 adult female Mexican health workers. METHOD: Longitudinal and cross-sectional analyses using data from adult women of the Health Workers Cohort Study (HWCS) Measures of body fat mass (kg from DEXA), dietary intake (kcal from FFQ), leisure time activity (METs/wk) and depression (CES-D) were determined in two waves (2004–2006 and 2010–2011). We explored the interrelation between body fat, diet, leisure time, physical activity, and depression using a cross-lagged effects model fitted to longitudinal data. We also fitted a structural equations model to cross-sectional data with body fat as the main outcome, and dietary intake and physical activity from leisure time as mediators between depression and body fat. RESULTS: Baseline depression was significantly related to higher depression, higher calorie intake, and lower leisure time physical activity at follow-up. From our cross-sectional model, each standard deviation increase in the depression score was associated with an average increase of 751 ± 259 g (± standard error) in body fat through the mediating effects of calorie intake and physical activity. CONCLUSIONS: The results of this study show how depression may influence energy imbalance between calories consumed and calories expended, resulting in higher body fat among those with a greater depression score. Evaluating the role of mental conditions like depression in dietary and physical activity behaviors should be positioned as a key research goal for better designed and targeted public health interventions. TRIAL REGISTRATION: The HealthWorkers Cohort Study (HWCS) has been approved by the Institutional IRB. Number: 2005–785-012.

    Abstract Early childhood development (ECD) is a critical stage in the intergenerational process of human development. Targeted interventions depend on accurate and up-to-date ECD measurements. This paper presents estimates for the nutritional and neurodevelopmental status of socially marginalized children in Mexico. We performed a cross-sectional study based on data collected in 2019-2020 during home visits to 1,176 children aged 0-38 months across 24 highly marginalized locations in Oaxaca. We assessed nutritional status according to the World Health Organization 2006 child-growth standards and ECD status using the Child Development Evaluation Test, 2nd Edition. We stratified results by sex. Prevalence of stunting was 5.3 percentage points (p.p.) higher (p = 0.023) in males (25.3%; 95% CI: 20.2%, 31.1%) compared to females (20.0%; 95% CI: 15.0%, 26.1%). Overall prevalence rates stood at 5.7% (95% CI: 4.0%, 8.1%) for underweight, 1.5% (95% CI: 0.9%, 2.7%) for wasting and 3.6% (95% CI: 2.3%, 5.7%) for overweight/obesity, with no significant differences by sex. Prevalence of normal development was 8.3 p.p. lower (p = 0.001) in males (39.3%; 95% CI: 34.5%, 44.4%) compared to females (47.6%; 95% CI: 41.6%, 53.6%). By development area, the highest prevalence of suboptimal outcomes among children with developmental lag or at risk of delay was observed in their gross motor and language skills: 24.1% (95% CI: 20.0%, 28.8%) and 38.6% (95% CI: 34.0%, 43.3%), respectively. The largest difference between the sexes was found in the language area. Our results show that childhood development strategies have been insufficient thus far in the studied population. Programs specifically designed to prevent ECD lags and bridge inequality gaps are urgently needed. Trial registration: ClinicalTrials.gov ID: NCT04210362.
