Objective. To identify correlates of HIV/STI prevalence among 13 cities with varying sizes of female sex worker (FSW) populations and municipal characteristics in Mexico. Materials and methods. FSWs underwent interviews and testing for HIV, syphilis, gonorrhea and chlamydia. Lo­gistic regression explored variations in HIV/STI prevalence. Results. Among FSWs (n=1 092), prevalence across 13 sites was: HIV: 0.4% (range: 0%-1.4%): syphilis: 7.8% (range: 0%-17.2%); chlamydia: 15.3% (range: 5.7%-32.2%); gonorrhea: 2.9% (range 0%-13.8%), and any HIV/STI: 23% (range: 9.9%- 46%). Municipalities with high human development scores and a lower municipal marginalization index had higher odds of combined HIV/STI prevalence. After controlling for site-specific variability in municipal characteristics, greater risk of HIV/STIs was associated with lower education, having a spouse diagnosed or treated for an STI, unaffordability of condoms, and having non-Mexican clients. Conclusions. Prevalence of HIV/STIs varies across Mexican municipalities indicating the need for surveillance to identify hotspots for targeted resource allocation.

Objetivo. Asociar una nueva e integradora clasificación de actividad física (AF) y sedentarismo con riesgo de síndrome metabólico (SM) en una muestra representativa de adultos chilenos. Material y métodos. Se incluyeron 5 040 parti­cipantes de la Encuesta Nacional de Salud de Chile 2009-2010. Fueron creadas cuatro categorías mediante una combinación entre niveles de AF y sedentarismo (SED) usando el cuestio­nario GPAQ. El SM fue definido según las normas del NCEP ATP-III. Resultados. Se observa una menor probabilidad de presentar SM sólo en las categorías que cumplen con las recomendaciones internacionales de AF (p<0.05), “activo y bajo-SED” (RM=0.72 [0.57 a 0.91]) y “activo y alto-SED” (RM=0.63 [0.49 a 0.81]). El nivel de sedentarismo (alto/bajo) no se asoció con una reducción significativa de SM en ninguno de los grupos. Conclusiones. Este tipo de clasificación de­muestra que la principal estrategia para reducir el riesgo de SM debiera estar asociada con cumplir las recomendaciones de AF. 

 Objective. To analyze the association of total globalization and its different dimensions with overweight and obesity in 10 Latin American and Caribbean (LAC) countries between 1995 and 2013. Materials and methods. A sample of 848 405 women aged 20-49 was analyzed. Multiple logistic regression models were used, adjusting for individual- and country-level confounding factors. To evaluate nonlineari­ties, four levels were defined through quartiles and divided into four dummy variables. Results. Total globalization had a positive association with overweight and obesity. Three dimensions of globalization (economic, political and social) indicated an increase in overweight and obesity. Social global­ization presented polynomial behaviour, whereas, in political and economic globalization, a concave relation was observed. Conclusion. The economic, political and social dimensions had a positive association with overweight and obesity.
