title: Obesidad y Esperanza de Vida en México Obesity and life expectancy in Mexico.
abstract: The high and increasing prevalence of overweight and obesity in Latin American and the Caribbean and the increasing prevalence of some obesity-related chronic diseases could be changing the current mortality patterns and the improvements in life expectancy of this population. The main objective of this study is to measure the effect of overweight and obesity on mortality in Mexico among elderly people (60 years and older). We use the Mexican Health and Ageing Study (MHAS, 2001 and 2003) that is a panel nationally-representative study of the population 50 years and older in Mexico. Our results show that excess body weight (defined by the two highest quintiles of Body Mass Index-BMI-) increases the risk of mortality at 60 years and older in Mexico. As much as 11% of the deaths among elderly that occurred during the period 2001-2003 in Mexico would have been avoided if overweight and obese people (individuals belonging to the highest two quintiles of BMI) had had the "ideal" weight (defined by the middle quintile, or third quintile, of BMI). At individual level, we estimate that individuals 60 years old with excess body weight (fourth and fifth quintiles of BMI) survive four years less, in average, than individuals with normal body weight (third quintile of BMI).
