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.
