METHODOLOGY: a transversal study was undertaken, with representative sampling of 1,131 students from the 1st to 8th grades, with the use of three instruments: anthropometric card; Body Shape Questionnaire and Tanner classification. The outcome was categorized according to the Body Mass Index (BMI). Data analysis was performed with multivariate ordinal logistic regression. RESULTS: suitability of the nutritional state was found in 64.3% of students; 31.1% were overweight/obese, 6.4% hadmalnutrition and 8.2% were atrisk of being underweight. Considering separately the 476 young people from the 5th to the 8th grade, students from rural schools were 33 times more overweight/obese than those from the urban area. Youngsters concerned about their body image had three times more chances of having malnutrition/nutritional risk and were 11 times more overweight/obese. CONCLUSION: the high prevalence of overweight/obesity demands greater concern by health and education areas, especially with students at rural schools.
