Satisfaction with body weight among adolescents with excess weight: findings from a cross-sectional population-based study

ABSTRACT BACKGROUND: Individuals who are overweight or obese often underestimate their size, and they are less likely to consider their weight status to be a health problem and consequently to make lifestyle changes. OBJECTIVES: To estimate the proportion of satisfaction with weight among adolescents classified as overweight/obese, according to sociodemographic factors, morbidities and health-related behaviors. DESIGN AND SETTING: Cross-sectional population-based study conducted among adolescents aged 10 to 19 years in the city of Campinas (SP), Brazil. METHODS: The sample (n = 217) included participants with self-reported weight and height who were classified as overweight or obese, based on body mass index (BMI) according to age-specific cutoff points recommended by the World Health Organization. Participants whose answer to the question: “Would you like to gain or lose weight?” was “no” (i.e. no change) were deemed to be satisfied with their body weight. Odds ratios and 95% confidence intervals (95% CI) were calculated using logistic regression. RESULTS: The proportions of the respondents who were satisfied with their weight were 75.8% (95% CI: 65.3-83.9) among the overweight adolescents and 24.2% (95% CI: 16.1-34.7) among the obese adolescents (P < 0.01). Satisfaction was lower among individuals aged 15 to 19 years (versus 10 to 14 years), those born outside of Campinas (versus in Campinas), those with ≥ 8 household appliances (versus < 8), and those reporting ≥ two health complaints (versus none). CONCLUSIONS: More than half of the overweight adolescents and almost a quarter of the obese adolescents were satisfied with their weight. These results support the need for strategies for healthy weight management among Brazilian adolescents.

摘要 研究背景：超重或肥胖人群往往会低估自身体型，且更少将自身体重状况视为健康问题，因此也更难做出生活方式上的改变。
研究目的：基于社会人口学因素、共患病与健康相关行为，估算被归类为超重/肥胖的青少年对自身体重的满意度占比。
研究设计与研究场景：此项基于人群的横断面研究于巴西圣保罗州坎皮纳斯市开展，研究对象为10至19岁的青少年。
研究方法：本研究样本量为217例，纳入了自我报告身高与体重、且根据世界卫生组织（World Health Organization）推荐的年龄别截断点计算的体质指数（body mass index，BMI）被归类为超重或肥胖的参与者。针对“您是否希望增重或减重？”这一问题回答“否”（即无需改变体重）的参与者，被视为对自身体重感到满意。采用logistic回归计算比值比与95%置信区间（95% CI）。
研究结果：超重青少年中对自身体重感到满意的占比为75.8%（95% CI：65.3~83.9），肥胖青少年中该占比为24.2%（95% CI：16.1~34.7），组间差异具有统计学意义（P < 0.01）。15至19岁年龄段人群、非坎皮纳斯出生人群、家庭家用电器数量≥8件人群、自述存在≥2项健康不适症状人群的体重满意度均低于对照组（分别对应10至14岁年龄段、坎皮纳斯出生人群、家庭家用电器数量<8件人群、无健康不适症状人群）。
研究结论：超过半数的超重青少年与近四分之一的肥胖青少年对自身体重感到满意。上述结果表明，巴西青少年群体亟需开展健康体重管理相关策略。
