Migration as a determinant of childhood obesity in the United States and Latin America

International migration has economic and health implications. The acculturation process to the host country may be linked to childhood obesity. We use the Community Energy Balance (CEB) framework to analyze the relationship between migration and childhood obesity in Mexican households with international migrants. Using longitudinal data from the Mexican Family Life Survey (MxFLS), we examine how migrant networks affect childhood obesity in origin communities. We also review binational health programs that could be effective at tackling childhood obesity in migrant households from Mexico. Children embedded in migrant networks are at greater risk of developing overweight or obesity, suggesting a significant relationship between childhood obesity and international migration in Mexican households. Based on our search criteria, our analysis of health outreach programs shows that Ventanillas de Salud (VDS)/Health Windows has great promise to prevent childhood obesity in a culturally sensitive and trustful environment. The CEB framework is useful to understand how migration contributes to the risk of childhood overweight and obesity in migrant households. VDS is a feasible and replicable strategy with great potential to address childhood obesity among migrant families accounting for the dynamic and binational determinants of childhood obesity

Trends in food and beverage purchases in informal, mixed, and formal food outlets in Mexico: ENIGH 1994–2020

BackgroundThe retail food environment in Mexico is characterized by the co-existence of both, formal and informal food outlets. Yet, the contribution of these outlets to food purchases over time has not been documented. Understanding the longitudinal trends where Mexican households purchase their foods is critical for the development of future food retail policies.MethodsWe used data from Mexico’s National Income and Expenditure Survey from 1994 to 2020. We categorized food outlets as formal (supermarkets, chain convenience stores, restaurants), informal (street markets, street vendors, acquaintances), and mixed (fiscally regulated or not. i.e., small neighborhood stores, specialty stores, public markets). We calculated the proportion of food and beverage purchases by food outlet for each survey for the overall sample and stratified by education level and urbanicity.ResultsIn 1994, the highest proportion of food purchases was from mixed outlets, represented by specialty and small neighborhood stores (53.7%), and public markets (15.9%), followed by informal outlets (street vendors and street markets) with 12.3%, and formal outlets from which supermarkets accounted for 9.6%. Over time, specialty and small neighborhood stores increased 4.7 percentage points (p.p.), while public markets decreased 7.5 p.p. Street vendors and street markets decreased 1.6 p.p., and increased 0.5 p.p. for supermarkets. Convenience stores contributed 0.5% at baseline and increased to 1.3% by 2020. Purchases at specialty stores mostly increased in higher socioeconomic levels (13.2 p.p.) and metropolitan cities (8.7 p.p.) while public markets decreased the most in rural households and lower socioeconomic levels (6.0 p.p. & 5.3 p.p.). Supermarkets and chain convenience stores increased the most in rural localities and small cities.ConclusionIn conclusion, we observed an increase in food purchases from the formal sector, nonetheless, the mixed sector remains the predominant food source in Mexico, especially small-neighborhood stores. This is concerning, since these outlets are mostly supplied by food industries. Further, the decrease in purchases from public markets could imply a reduction in the consumption of fresh produce. In order to develop retail food environment policies in Mexico, the historical and predominant role of the mixed sector in food purchases needs to be acknowledged

Mortality amenable to healthcare in Latin American cities: a cross-sectional study examining between-country variation in amenable mortality and the role of urban metrics.

BACKGROUND: This study examined the variation in city-level amenable mortality, i.e. mortality due to conditions that can be mitigated in the presence of timely and effective healthcare, in 363 Latin American cities and measured associations between amenable-mortality rates and urban metrics. METHODS: We used death records from 363 cities with populations of >100 000 people in nine Latin American countries from 2010 to 2016. We calculated sex-specific age-adjusted amenable-mortality rates per 100 000. We fitted multilevel linear models with cities nested within countries and estimated associations between amenable mortality and urban metrics, including population size and growth, fragmentation of urban development and socio-economic status. RESULTS: Cities in Mexico, Colombia and Brazil had the highest rates of amenable mortality. Overall, >70% of the variability in amenable mortality was due to between-country heterogeneity. But for preventable amenable mortality, those for which the healthcare system can prevent new cases, most of the variability in rates occurred between cities within countries. Population size and fragmentation of urban development were associated with amenable mortality. Higher fragmentation of urban development was associated with lower amenable mortality in small cities and higher amenable mortality in large cities. Population growth and higher city-level socio-economic status were associated with lower amenable mortality. CONCLUSIONS: Most of the variability in amenable mortality in Latin American cities was due to between-county heterogeneity. However, urban metrics such as population size and growth, fragmentation of urban development and city-level socio-economic status may have a role in the distribution of amenable mortality across cities within countries

Adherence to Dietary Guidelines in Adults by Diabetes Status: Results From the 2012 Mexican National Health and Nutrition Survey

The aims of the present study were to compare the adherence to dietary guidelines and evaluate potential differences in nutrient profiles among adults by diabetes status. We used the Mexican Alternate Healthy Eating Index (MxAHEI) to evaluate adherence to dietary guidelines. We calculated the MxAHEI scores (total and by dietary component) with scales from 0 (non-adherence) to 100 (perfect adherence) based on a food frequency questionnaire. Mean daily intakes of macronutrients and micronutrients (g, mg, mcg/1000 kcal per day) were also estimated by diabetes status. Sex-specific, multivariable linear regression models were estimated to test whether MxAHEI scores as well as nutrient intakes were different by diabetes status. Mexican adults had low adherence to the dietary guidelines irrespective of their diabetes status (score < 50 points). Among men, the MxAHEI score was 2.6 points higher among those with diabetes than those without diabetes (46.9; 95% confidence intervals (CI): 44.6, 49.2 vs. 44.3; 95% CI: 44.2, 45.6, respectively). Among women, the total MxAHEI score was similar in individuals with diabetes compared to those without diabetes. Lower intakes of carbohydrates and added sugars and higher intakes of protein, calcium, and zinc were observed in individuals with diabetes. Our findings support the development of strategies focused on promoting dietary patterns that can help to prevent and control the disease

La migración como determinante de la obesidad infantil en Estados Unidos y Latinoamérica

La migración internacional tiene consecuencias económicas y en la salud. El proceso de aculturación en el país de acogida puede estar relacionado con la obesidad infan-til. Utilizamos el marco conceptual del balance energético comunitario (CEB, por sus siglas en inglés) para analizar la relación entre migración y obesidad infantil en los hogares mexicanos con migrantes internacionales. Utilizando datos longitudinales de la Encuesta Nacional de Niveles de Vida de los Hogares de México (ENNViH), exami-namos cómo influyen las redes de migrantes sobre la obesidad infantil en las comuni-dades de origen. También revisamos programas de salud binacionales que podrían ser eficaces para abordar la obesidad infantil en los hogares de migrantes procedentes de México. Los niños que forman parte de las redes de migrantes presentan un mayor riesgo de desarrollar sobrepeso y obesidad, lo cual sugiere una relación significativa entre la obesidad infantil y la migración internacional en los hogares mexicanos. Basán-donos en los criterios de búsqueda que habíamos definido, realizamos un análisis de programas de extensión comunitaria en salud cuyos resultados indican que las Ven-tanillas de Salud (VDS) son una opción prometedora para prevenir la obesidad infan-til en un entorno de confianza y culturalmente sensible. El marco conceptual CEB es útil para comprender cómo contribuye la migración al riesgo de sobrepeso y obesidad infantil en los hogares de los migrantes. Las VDS son una estrategia viable y replicable con un gran potencial para abordar la obesidad infantil entre las familias migrantes y que toma en cuenta los determinantes dinámicos y binacionales de la obesidad infanti

City-Level Travel Time and Individual Dietary Consumption in Latin American Cities: Results from the SALURBAL Study.

There is limited empirical evidence on how travel time affects dietary patterns, and even less in Latin American cities (LACs). Using data from 181 LACs, we investigated whether longer travel times at the city level are associated with lower consumption of vegetables and higher consumption of sugar-sweetened beverages and if this association differs by city size. Travel time was measured as the average city-level travel time during peak hours and city-level travel delay time was measured as the average increase in travel time due to congestion on the street network during peak hours. Vegetables and sugar-sweetened beverages consumption were classified according to the frequency of consumption in days/week (5-7: frequent, 2-4: medium, and ≤1: rare). We estimate multilevel ordinal logistic regression modeling for pooled samples and stratified by city size. Higher travel time (Odds Ratio (OR) = 0.65; 95% Confidence Interval (CI) 0.49-0.87) and delay time (OR = 0.57; CI 0.34-0.97) were associated with lower odds of frequent vegetable consumption. For a rare SSB consumption, we observed an inverse association with the delay time (OR = 0.65; CI 0.44-0.97). Analysis stratified by city size show that these associations were significant only in larger cities. Our results suggest that travel time and travel delay can be potential urban determinants of food consumption
