To estimate the prevalence of overweight and to identify associations with sociodemographic, biological and lifestyle factors in adolescents from Florianopolis, Santa Catarina, Brazil.
Cross-sectional study carried out in 2007 with a probabilistic sample of 1,590 schoolchildren aged from 11 to 14 years old. The prevalence of overweight, based on body mass index, was estimated by the Brazilian reference and the International Obesity Task Force (IOTF). Multivariate analysis expressed as odds ratios were used to identify associations with sociodemographic, biological and lifestyle factors among adolescents.
The prevalence of overweight was 19.3% (24.5% in boys and 14.5% in girls) using the IOFT reference, and 25.8% (31.8% in boys and 20.5% in girls) by the Brazilian reference. Among male adolescents, overweight was positively associated with unbalanced food consumption and inactive commuting to school. Among girls, the factors associated with overweight were: mother's overweight, unbalanced food consumption and discordance between stages for sexual maturity indicators.
The consumption of foods with high nutritional value was a protective factor against overweight among adolescents. This finding reinforces the importance of actions aimed at changing behaviors related to the family environment by encouraging the incorporation of healthy eating and active leisure time.
评估巴西圣卡塔琳娜州弗洛里亚诺波利斯市青少年超重的患病率，并确定其与社会人口学、生物学和生活方式因素之间的关联。
2007年开展的一项横断面研究，对1590名11至14岁的学童进行概率抽样。基于体重指数，采用巴西参考标准和国际肥胖特别工作组（IOTF）标准估算超重患病率。多变量分析以比值比表示，用于确定青少年中社会人口学、生物学和生活方式因素之间的关联。
采用IOTF标准时，超重患病率为19.3%（男孩为24.5%，女孩为14.5%）；采用巴西参考标准时，超重患病率为25.8%（男孩为31.8%，女孩为20.5%）。在男性青少年中，超重与不均衡的食物消费和非主动上学通勤呈正相关。在女孩中，与超重相关的因素有：母亲超重、不均衡的食物消费以及性成熟指标各阶段之间的不一致。
食用高营养价值食物是青少年预防超重的一个保护因素。这一发现强化了旨在通过鼓励健康饮食和积极的休闲时间来改变与家庭环境相关行为的行动的重要性。
