To associate the nutritional status of elementary schoolchildren with their gender, age group, and economic status based on a cross-sectional study carried out at public schools in the municipality of Cruzeiro do Oeste, Southern Brazil.
The study was performed in 2010 including 939 schoolchildren aged six to ten years-old. The economical status of the families was classified based on a socioeconomic ranking questionnaire (Brazilian Association of Survey Companies), and the body mass index was calculated. Data were analyzed by descriptive statistics, and differences between independent groups were verified by Mann-Whitney and Kruskal-Wallis tests, while possible associations were verified by the chi-square test, being significant p<0.05.
The prevalence of obesity in the sample was 8.0%, and overweight, 16.4%. No association was found between the socioeconomic and nutritional status or between the nutritional status and gender.
A high prevalence of overweight and obesity was found in this study, indicating that children of both genders are affected regardless of their economical status and age.
基于在巴西南部克鲁塞罗-杜奥este市公立学校开展的一项横断面研究，将小学生的营养状况与其性别、年龄组和经济状况相关联。
该研究于2010年进行，纳入了939名6至10岁的学童。根据社会经济排名问卷（巴西调查公司协会）对家庭经济状况进行分类，并计算体重指数。数据采用描述性统计进行分析，独立组之间的差异通过曼-惠特尼检验和克鲁斯卡尔-沃利斯检验进行验证，而可能的关联通过卡方检验进行验证，p<0.05具有显著性。
样本中肥胖患病率为8.0%，超重患病率为16.4%。未发现社会经济状况与营养状况之间或营养状况与性别之间存在关联。
本研究发现超重和肥胖的患病率较高，表明无论经济状况和年龄如何，两个性别的儿童均受到影响。
