Objetivo. Analizar la cobertura de la educación sexual integral (ESI) en México y describir su integralidad, homogeneidad y continuidad en cuanto a contenidos sobre salud sexual yreproductiva, autoeficacia, derechos y relaciones. Material y métodos. En una encuesta probabilística transversal con muestreo estratificado y por conglomerados, se aplicó uncuestionario sobre ESI a una muestra representativa a nivel nacional de 3 824 adolescentes de 45 escuelas de educación media superior públicas y privadas, en localidades urbanasy rurales. Resultados. El porcentaje de adolescentes que reportan recibir educación sexual integral varía dependiendo de los temas y nivel escolar. Los temas más frecuentes estánrelacionados con salud sexual y reproductiva; los menos tratados con derechos y relaciones. Los contenidos de educación sexual se trasmiten mayoritariamente durante la escuela secundaria. Conclusiones. Se requiere garantizar la integralidad, homogeneidad y continuidad de los contenidos de la ESI, asegurando que se imparta la totalidad de los temas planteados en recomendaciones nacionales e internacionales.

BackgroundSeveral strategies have been proposed to reduce the intake of added sugars in the population. In Mexico, a 10% sugar-sweetened beverages (SSBs) tax was implemented in 2014, and the implementation of other nutritional policies, such as product reformulation to reduce added sugars, is under discussion. WHO recommends that all individuals consume less than 10% of their total energy intake (TEI) from added sugars. We propose gradually reducing added sugars in SSBs to achieve an average 10% consumption of added sugars in the Mexican population over 10 years and to estimate the expected impact of reformulation in adult body weight and obesity.Methods and findingsBaseline consumption for added sugars and SSBs, sex, age, socioeconomic status (SES), height, and weight for Mexican adults were obtained from the 2012 Mexico National Health and Nutrition Survey (ENSANUT). On average, 12.6% of the TEI was contributed by added sugars; we defined a 50% reduction in added sugars in SSBs over 10 years as a reformulation target. Using a dynamic weight change model, sugar reductions were translated into individual expected changes in body weight assuming a 43% caloric compensation and a 2-year lag for the full effect of reformulation to occur. Results were stratified by sex, age, and SES. Twelve years after reformulation, the TEI from added sugars is expected to decrease to 10%, assuming no compensation from added sugars; 44% of the population would still be above WHO recommendations, requiring further sugar reductions to food. Body weight could be reduced by 1.3 kg (95% CI −1.4 to −1.2) in the adult population, and obesity could decrease 3.9 percentage points (pp; −12.5% relative to baseline). Our sensitivity analyses suggest that the impact of the intervention could vary from 0.12 kg after 6 months to 1.52 kg in the long term.ConclusionsReformulation to reduce added sugars in SSBs could produce large reductions in sugar consumption and obesity in the Mexican adult population. This study is limited by the use of a single dietary recall and by data collected in all seasons except summer; still, these limitations should lead to conservative estimates of the reformulation effect. Reformulation success could depend on government enforcement and industry and consumer response, for which further research and evidence are needed.

Objective: Using newly harmonised individual-level data on health and socio-economic environments in Latin American cities (from the Salud Urbana en América Latina (SALURBAL) study), we assessed the association between obesity and education levels and explored potential effect modification of this association by city-level socio-economic development. Design: This cross-sectional study used survey data collected between 2002 and 2017. Absolute and relative educational inequalities in obesity (BMI ≥ 30 kg/m2, derived from measured weight and height) were calculated first. Then, a two-level mixed-effects logistic regression was run to test for effect modification of the education–obesity association by city-level socio-economic development. All analyses were stratified by sex. Setting: One hundred seventy-six Latin American cities within eight countries (Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Mexico and Peru). Participants: 53 186 adults aged >18 years old. Results: Among women, 25 % were living with obesity and obesity was negatively associated with educational level (higher education–lower obesity) and this pattern was consistent across city-level socio-economic development. Among men, 18 % were living with obesity and there was a positive association between education and obesity (higher education–higher obesity) for men living in cities with lower levels of development, whereas for those living in cities with higher levels of development, the pattern was inverted and university education was protective of obesity. Conclusions: Among women, education was protective of obesity regardless, whereas among men, it was only protective in cities with higher levels of development. These divergent results suggest the need for sex- and city-specific interventions to reduce obesity prevalence and inequalities.

Access to information about contraception in pharmacies and clinics is high, but efforts must be made to provide 100% coverage to adolescents. The quality of contraception services in pharmacies and clinics is poor and nonequitable, favoring older and nonindigenous adolescents. Clinics and pharmacies must strive to comply with international AFS guidelines.
