Overweight and obesity trends in mexican children 2 to 18 years of age from 1988 to 2006

Abstract

Objective: To describe prevalences and trends of overweight and obesity/OW&OB in Mexican children from 1988 to 2006 at the national level and by relevant subpopulations. Material and Methods: Prevalences of OW&OB in children aged 2-18 years were estimated using body mass index data from three national surveys conducted in 1988, 1999 and 2006. Results: Prevalences of OW&OB are high in children of all ages, particularly among school-age and adolescent groups disaggregated by regions, socioeconomic status, urban and rural areas, and ethnic groups. The overall prevalence of OW&OB in children 2 to 18 years old in 2006 was 26.3%. Prevalences by age groups were 16.7% in preschool-age, 26.2% in school-age, and 30.9% in adolescents, using the IOTF classification system. Conclusions: Upward trends were observed in school-age children and adolescents at the national level and in all subpopulations.
