目的：本研究的目的是确定巴西南部城市青少年超重的患病率，并确定性别差异以及与社会经济和人口条件、家庭因素和个人行为的关系。方法：基于横断面人口的研究，对巴西南部城市的家庭进行随机整群抽样，包括 722 名青少年（10-19 岁）。体重指数 (BMI) 是根据国家健康和统计中心参考曲线计算的，将 BMI >= 85% 定义为超重。结果：女孩超重率为 17%，男孩为 19%。在多变量泊松回归中，父母和最多四人家庭的慢性疾病与男孩超重有关，而纤维摄入量低、看电视时间较长和经常锻炼与女孩超重有关。结论：巴西青少年超重患病率较高，相关因素存在性别差异。学校和公共卫生服务机构的卫生工作者应意识到这些差异，以便改进该年龄段的预防和治疗策略。 (C) 2007 年皇家公共卫生研究所。由 Elsevier Ltd. 出版。保留所有权利。
Objective: The aim of this study was to determine the prevalence of overweight in adolescents in a southern Brazilian city, and ascertain gender differences and association with socio-economic and demographic conditions, family factors and individual behaviours.Methods: Cross-sectional population-based study with random cluster sampling of households, including 722 adolescents (10-19 years), from a city in southern Brazil. Body mass index (BMI) was calculated based on the National Center for Health and Statistics reference curve, defining overweight as BMI >= 85th percentile.Results: Prevalence of overweight was 17% in girls and 19% in boys. In multivariate Poisson regression, chronic illness in parent(s) and household of up to four people were associated with overweight in boys, whereas low fibre intake, more hours spent watching television and regular exercise were associated with overweight in girls.Conclusion: The prevalence of overweight in Brazilian adolescents is high, with gender differences in associated factors. Health workers in schools and public health services should be aware of these differences in order to improve preventive and therapeutic strategies in this age group.
