To describe the percentile distribution of body mass index (BMI) in school adolescents, by gender and age, comparing them with international parameters.
The study included 8,020 adolescents aged 10-15 years from 43 schools in the city of São Paulo, southeastern Brazil. BMI values of the study sample were distributed in percentiles and compared to international parameters (CDC, Must and cols. and Cole and cols.).
Both male and female adolescents aged 10 to 14 years showed BMI cut-offs over the international parameters, especially in the P50-P85 percentile range. At the age of 15, the observed values were very similar to reference data; however, BMI values in the 95th percentile were much higher than international parameters.
The study results show how important it is to use adequate BMI values for Brazilian adolescents aged 10-15 since international parameters may not reflect the actual nutritional status of this group.
按性别和年龄描述在校青少年体重指数（BMI）的百分位数分布，并与国际参数进行比较。
该研究纳入了巴西东南部圣保罗市43所学校的8020名10至15岁的青少年。研究样本的BMI值按百分位数分布，并与国际参数（美国疾病控制与预防中心、穆斯特等人以及科尔等人）进行比较。
10至14岁的男性和女性青少年的BMI临界值均高于国际参数，尤其是在第50至85百分位数范围内。15岁时，观察值与参考数据非常相似；然而，第95百分位数的BMI值远高于国际参数。
研究结果表明，对于10至15岁的巴西青少年，使用适当的BMI值非常重要，因为国际参数可能无法反映该群体的实际营养状况。
