[Obesity in Mexico: epidemiology and health policies for its control and prevention]

Obesity is a major risk factor for developing type 2 diabetes, cardiovascular disease, hypertension, dyslipidemias, musculoskeletal diseases, and certain types of cancer. In Mexico the prevalence of overweight and obesity is 16.7% in preschool children, 26.2% in school children, and 30.9% in adolescents. For adults, the prevalence of overweight and obesity is 39.7 and 29.9%, respectively (ENSANUT 2006). Based on an analysis of the situation in Mexico, the need for a comprehensive, multisectoral, multilevel policy and an effective coordination policy have been clearly identified to achieve changes in eating patterns and physical activity to enable the prevention of chronic diseases and to reduce the prevalence of overweight and obesity The combination of strategies and actions of the Mexican National Agreement for Healthy Nutrition proposed by the federal government proposes among its aims for 2012: a reversal in the prevalence of overweight and obesity for children aged 2-5 years in comparison with ENSANUT to stop the increasing prevalence in this condition for school children and adolescents (aged 5-19 years), and to slow down the increasing prevalence of overweight and obesity in adults. This challenge will require important regulatory actions, efficient and adaptable implementation, and participation of all sectors of society.
