Prevalence of self-reported overweight-obesity and its association with socioeconomic and health factors among older Mexican adults.

To investigate the prevalence of obesity and its association with socioeconomic factors and comorbidities in a population-based study.Data were examined from 4,605 persons ages 60 and older that participated in the 2001 Mexican Health and Aging Study, conducted in rural and urban communities in Mexico. The prevalence of obesity (according to self-reported weight and height) was obtained, stratified by age, and logistic regression was used to study cross-sectional associations between obesity and socioeconomic factors.Of the population studied, 20.9% were classified as obese and the prevalence diminishes with age. Overall, women were more likely than men to be obese. Lower educational level was associated with lower risk of overweight. In both men and women, obesity was more common between subjects with hypertension (OR 1.38 and 1.71, respectively) and long-distance walk limitation (OR 2.08 and 2.21, respectively).In older Mexican adults, hypertension and long-distance walk limitation were independent associated factors for higher prevalence of obesity.
