We evaluated associations between social, built, and natural environment characteristics of neighbourhoods with BMI, and investigated whether these associations were modified by individual socioeconomic position (SEP). Methods We linked individual data (n = 43 968) from national health surveys to data on neighbourhoods (n = 3428) and cities (n = 165) in Argentina, Chile, Colombia, and Mexico. Linear mixed models were used to estimate associations between neighbourhood education, intersection density, and greenness with BMI, adjusting for individual- and city-level characteristics. Results Associations between neighbourhood education and BMI varied by country, in both magnitude and direction. In Argentina and Chile, higher neighbourhood education was associated with lower BMI. This negative association was also observed among women in Colombia and Mexico, although it was weaker. Among men in Colombia and Mexico, however, the association was positive. Associations of neighbourhood intersection density and greenness with BMI were less robust. In general, we did not find strong evidence of effect modification by individual SEP. Conclusion Neighbourhood education is associated with BMI beyond individual and city characteristics, although the associations are heterogenous across countries and by gender. Associations with built and natural features were less clear. Our results highlight the relevance of context-specific analysis for planning interventions that are aimed to reduce BMI and its unequal distribution in Latin American cities.","PeriodicalId":14147,"journal":{"name":"International journal of epidemiology","volume":"43 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the pandemic, Mexico experienced sizable excess mortality. We aimed to assess the contribution of violence, COVID-19, and causes of death that were amenable to healthcare to life-expectancy changes between 2015 and 2022 in Mexico.METHODSWe used administrative mortality and adjusted population estimates to construct life tables. We applied demographic methods to untangle contributions of causes of death to life-expectancy changes by year and sex at the subnational level.RESULTSBetween 2015 and 2019, life expectancy declined from 71.8 to 71.1 years for males and stagnated at 77.6 years for females. Violence among young males explains most of the decline (54.3%). Between 2019 and 2020, life expectancy decreased by 7.1 and 4.4 years for males and females, respectively. COVID-19 accounted for 55.4% of that change for males and 57.7% for females. In 2021, male life expectancy stagnated but continued to decline for females by 0.44 years due to COVID-19 deaths. In 2022, we observed unequal recovery patterns in life expectancy across regions, as northern states experienced larger improvements than central and southern states.CONCLUSIONWe documented large variations in life-expectancy losses across Mexican states before, during, and after the COVID-19 pandemic. Before the pandemic, violence accounted for most of the male life-expectancy losses. During the pandemic, following COVID-19 deaths, mortality due to diabetes and causes that were amenable to healthcare contributed considerably to observed losses, with an uneven impact on the sexes.","PeriodicalId":14147,"journal":{"name":"International journal of epidemiology","volume":"272 1","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pooled estimates using participant-level data from multiple cohort studies may provide more conclusive evidence. Methods Four prospective cohort studies conducted in England, Finland, France, and the USA were used (age 36–62 years; n = 41 760). We studied 34 903 and 36 076 individuals who had baseline (1981–2005) information on self-reported psychosocial and physical work demands, respectively. All-cause mortality until the year 2018 was ascertained through linkage to national registers, National Death Index, and company databases. We investigated the associations of psychosocial and physical demands with all-cause mortality separately for females and males using Cox regression models that were adjusted for socio-demographic and lifestyle factors. Using random-effects meta-analysis, we calculated pooled estimates of all-cause mortality for moderate and high exposure levels. Results During the mean follow-up of 25 years, 2105 deaths occurred among females and 5048 deaths occurred among males with information on psychosocial demands. The corresponding numbers for those with information on physical demands were 2176 and 5101. Fully adjusted models indicated that psychosocial demands were associated with both lower and higher all-cause mortality risks in both sexes. Physical demands increased the risk of all-cause mortality in both sexes and the association was strongest among males with moderate exposure levels (pooled hazard ratio 1.10, 95% confidence interval 1.02–1.19).
