Obesity has been recognized as a public health problem in developed countries because its association with increased risk for several pathologies. Obesity in children and, specifically, in adolescents, is a major concern. Actually, in Spain, the prevalence rates of childhood overweight and obesity are among the highest in European countries. The objective of this study was to measure the prevalence of overweight and obesity in children from Seville. Method: A cross-sectional study was performed on 990 children, aged 8-9 years old (51.5% 8-year old and 48.5% 9-year old). Overweight and obesity were defined according to two methods: Spanish standards, applying the criterion of BMI-specific percentiles for age and sex, and the international standards established by Cole et al. (IOTF). Results: A high prevalence of overweight (11%) and obesity (22%) was observed. The prevalence of obesity as well as the prevalence of overall excess weight was significantly higher in 9-year old children (28% and 41%, respectively) than in 8-year old children (17% and 27%, respectively). Conclusion: The prevalence of overweight and obesity among Sevillian school children is high, and increases in the studied range of age.
