To identify the prevalence of overweight in adolescents according to different classification criteria for obesity and somatic maturation stages.
Cross-sectional study in 10 schools in a city from Southern Brazil, with 1715 adolescents. Height, weight, waist circumference, and neck circumference (NC) data were collected. Body Mass Index was classified according to World Health Organization (WHO) and Centers for Disease Control and Prevention criteria, and the waist-to-height ratio (WHtR) was classified according to Brazilian and European cut-off points. Somatic maturation was obtained through the Peak Height Velocity. The prevalence data were compared between sex and stages of somatic maturation; the concordance between different criteria was verified.
The prevalence of overweight was high in both sexes; WHO criteria showed that 34.5% of boys and 29.3% of girls were overweight. For the WHtR, the prevalence was 28.4% in boys and 23.7% in girls. NC classified 13.8% of boys and 15.8% of girls as being overweight. The prevalence of overweight was higher in adolescents before complete somatic maturation.
The prevalence of overweight was high among adolescents. The boys presented higher frequency of overweight, except if NC was used to classify them. Adolescents before somatic maturation had a higher prevalence of overweight. NC showed a lower ability to track obese adolescents.
根据肥胖和身体成熟阶段的不同分类标准，确定青少年超重的流行率。
这是一项横断面研究，在巴西南部一个城市的 10 所学校中进行，共纳入 1715 名青少年。收集身高、体重、腰围和颈围（NC）数据。根据世界卫生组织（WHO）和疾病控制与预防中心的标准对体重指数进行分类，根据巴西和欧洲的切点对腰高比（WHtR）进行分类。通过最大身高速度（PHV）获得身体成熟度。比较了性别和身体成熟阶段之间的超重流行率；验证了不同标准之间的一致性。
男女超重率均较高；根据 WHO 标准，34.5%的男孩和 29.3%的女孩超重。对于 WHtR，男孩的患病率为 28.4%，女孩为 23.7%。NC 将 13.8%的男孩和 15.8%的女孩归类为超重。在完全成熟之前，青少年超重的比例更高。
青少年超重的发生率较高。男孩超重的频率较高，除非使用 NC 进行分类。在身体成熟之前，超重的青少年比例更高。NC 显示出较低的识别肥胖青少年的能力。
