This cross-sectional study aimed to determine the prevalence of overweight and obesity in a group of 11-13-year-old schoolchildren in Capão da Canoa, Rio Grande do Sul State, Brazil, and to investigate the association with possible risk factors for excess body weight. The sample was stratified, proportional to the number of pupils in each school. Nutritional status was assessed by body mass index (BMI) cutoffs according to age and gender as proposed by Cole et al. (2000). Socioeconomic, demographic, genetic, and behavior variables were analyzed. 719 children from 11 schools were interviewed, of whom there were 541 (75.2%) with normal BMI, 153 (21.3%) with overweight, and 25 (3.5%) with obesity. Statistically significant associations were found with type of school, parents' nutritional status, level of physical activity, and time of sedentary behavior. Prevalence of overweight and obesity in these schoolchildren was high (24.8%), in keeping with the literature, confirming the problem's magnitude and severity in Brazil.
这项横断面研究旨在确定巴西南里奥格兰德州卡庞达卡诺阿市一组11至13岁学童中超重和肥胖的患病率，并调查与超重可能的风险因素之间的关联。样本按各学校学生人数比例分层。根据Cole等人（2000年）提出的年龄和性别标准，通过体重指数（BMI）临界值评估营养状况。分析了社会经济、人口统计学、遗传和行为变量。对来自11所学校的719名儿童进行了访谈，其中541名（75.2%）BMI正常，153名（21.3%）超重，25名（3.5%）肥胖。发现与学校类型、父母的营养状况、身体活动水平和久坐行为时间存在统计学上的显著关联。这些学童中超重和肥胖的患病率很高（24.8%），与文献一致，证实了该问题在巴西的严重程度。
