To evaluate the prevalence of weight excess in children and adolescents attending public and private schools of Campinas, Southeast Brazil, according to age group.
Cross-sectional study that enrolled 3,130 students from 2010 to 2012. The weight and the height were measured and the body mass index (BMI) was calculated. The students were classified by BMI Z-score/age curves of the World Health Organization (WHO)-2007 (thinness, normal weight, overweight and obesity) and by age group (7-10, 11-14 and 15-18 years). Multinomial logistic regression analysis was applied to verify variables associated to overweight and obesity.
Among the 3,130 students, 53.7% attended public schools and 53.4% were girls. The prevalence of weight excess (overweight or obesity) was higher in private schools (37.3%) than in public ones (32.9%) and among males (37.5%), compared to females (32.7%; p<0.05). The chance of having weight excess in children aged 7-10 years was more than twice of those over 15 years old (OR 2.4; 95%CI 2.0-3.0) and it was 60% higher for the group with 11-14 years old (OR 1.6; 95%CI 1.3-2.0). The chance of being obese was three times higher in 7-10 years old children than in the adolescents with 15-18 years old (OR 4.4; 95%CI 3.3-6.4) and 130% higher than the group with 11-14 years old (OR 2.3; 95%CI 1.6-3.2).
The prevalence of weight excess in Campinas keeps increasing at an alarming rate, especially in the younger age group.
根据年龄组评估巴西东南部坎皮纳斯公立和私立学校儿童及青少年超重的患病率。
2010年至2012年开展的横断面研究，纳入了3130名学生。测量体重和身高，并计算体重指数（BMI）。学生们根据世界卫生组织（WHO）-2007年的BMI Z评分/年龄曲线（消瘦、正常体重、超重和肥胖）以及年龄组（7-10岁、11-14岁和15-18岁）进行分类。应用多项逻辑回归分析来验证与超重和肥胖相关的变量。
在3130名学生中，53.7%就读于公立学校，53.4%为女生。私立学校超重（或肥胖）的患病率（37.3%）高于公立学校（32.9%），男性（37.5%）高于女性（32.7%；p<0.05）。7-10岁儿童超重的几率是15岁以上儿童的两倍多（比值比2.4；95%置信区间2.0-3.0），11-14岁组高出60%（比值比1.6；95%置信区间1.3-2.0）。7-10岁儿童肥胖的几率是15-18岁青少年的三倍（比值比4.4；95%置信区间3.3-6.4），比11-14岁组高出130%（比值比2.3；95%置信区间1.6-3.2）。
坎皮纳斯超重的患病率正以惊人的速度持续上升，尤其是在较年轻的年龄组。
