The scope of this article was to assess the association between dietary intake, physical activity and socioeconomic factors associated with body fat percentage in 7 to 14-year-old schoolchildren. It is a cross-sectional study with a probability sample of 2,481 students from public and private schools in Florianópolis, Santa Catarina, Brazil. Body fat percentage was investigated by measuring triceps and subscapular skin folds. Poisson regression was performed to test the association between excess body fat and independent variables, estimating prevalence ratios and 95% confidence intervals. The prevalence of excess body fat was 23.9%, though there was no significant difference between sex (p = 0.359) and age (p = 0.202). Excess body fat was associated with different factors in 11 to 14-year-old schoolchildren, namely eating less than three meals a day (OR = 1.62, CI: 1.38 to 1.91) and consumption of high-risk food more than 3 times a day (OR = 0.61 CI: 0.47 to 0.79). No significant difference was observed with physical activity. The high prevalence of excess body fat detected reveals the need for fostering the adoption of healthier behavioral practices (in relation to nutrition and physical activity) by schoolchildren.
本文的研究范围是评估7至14岁学童的饮食摄入、身体活动以及与体脂百分比相关的社会经济因素之间的关联。这是一项横断面研究，对来自巴西圣卡塔琳娜州弗洛里亚诺波利斯市公立和私立学校的2481名学生进行了概率抽样。通过测量肱三头肌和肩胛下皮褶厚度来调查体脂百分比。采用泊松回归分析来检验体脂过多与自变量之间的关联，估计患病率比和95%置信区间。体脂过多的患病率为23.9%，不过性别（p = 0.359）和年龄（p = 0.202）之间没有显著差异。在11至14岁的学童中，体脂过多与不同因素有关，即每天用餐少于三餐（OR = 1.62，CI：1.38至1.91）以及每天食用高风险食物超过3次（OR = 0.61，CI：0.47至0.79）。未观察到身体活动方面的显著差异。所检测到的体脂过多的高患病率表明，有必要促使学童采用更健康的行为方式（在营养和身体活动方面）。
