Abstract
RIOS-FETCHKO, Francine; FERNANDEZ, Alicia; MEJIA, Raúl and SALGADO, M. Victoria. Disparities in regional obesity rates in argentina by socioeconomic status. Medicina (B. Aires) [online]. 2023, vol.83, n.3, pp.366-375. ISSN 0025-7680.
Background
: Obesity rates in Latin America are increasing overall and among people with low socio economic status (SES). Obesity and SES disparities can vary by region-a valuable indicator of local drivers. The objective of this study was to examine regional and SES differences in obesity in Argentina.
Methods
: We used data from Argentina’s 4th Na tional Risk Factors Survey (n = 29226) 2018 and defined obesity as BMI ≥ 30. Low SES was defined as not fin ished high school or having a household income in the lowest two quintiles. Descriptive analysis stratified by sex compared obesity rates by SES, province, and re gion. Age-adjusted logistic regression models explored the association between obesity, socioeconomic status, and region.
Results
: Obesity rates varied more by SES among women (39% for low SES vs. 26% for middle/high SES; p < 0.001) than among men (33% low SES vs. 29% middle/ high SES; p = 0.027). The Patagonian region had the high est obesity prevalence for both men (36%) and women (37%). A gender-stratified age-adjusted analysis with region and SES showed that low SES (OR 1.72, 95% CI 1.45, 2.03) and the Patagonian region (OR 1.29, 95% CI 1.02, 1.62) were the only significant predictors for women.
Conclusions
: SES associated disparities in obesity in Argentina were pronounced for women but not men. Disparities were particularly high in Patagonia. Further research is needed to understand the drivers behind these SES, regional, and gender disparities.
