Although racial/ethnic disparities in childhood obesity are well documented in the United States (U.S.), fewer studies have investigated elevated body mass index (BMI) and related health behaviors among sexual minority youth (SMY; gay/lesbian, bisexual, not sure). We examined pooled data from the 2009-2017 Youth Risk Behavior Surveys, which included high school students from 12 urban U.S. school districts. We used sex-stratified logistic regression models to estimate the association of sexual identity with health behaviors and elevated BMI (reference = heterosexual participants). A total of 133,615 participants were included. Sexual minority boys were more likely to report physical inactivity than heterosexual boys. Gay and not sure boys were also less likely to consume the recommended daily intake of fruit. Bisexual girls were more likely than heterosexual girls to report watching television ≥ 3 hours on a school day and to consume sugar-sweetened beverages (AOR 1.30, 95% CI= 1.18-1.43). All SMY reported higher rates of current tobacco use than their heterosexual peers. Sexual minority girls and bisexual boys had significantly higher rates of obesity than their heterosexual counterparts. These findings can inform tailored health promotion initiatives to reduce obesity risk in SMY.
尽管在美国，儿童肥胖的种族/民族差异有大量记录，但较少的研究调查了性少数青年（同性恋/女同性恋、双性恋、不确定）的体重指数升高和相关健康行为。我们分析了 2009-2017 年青少年风险行为调查的汇总数据，其中包括来自美国 12 个城市地区的高中生。我们使用按性别分层的逻辑回归模型来估计性身份与健康行为和体重指数升高的关联（参考组为异性恋参与者）。共纳入 133615 名参与者。与异性恋男孩相比，同性恋男孩更可能报告不活跃。同性恋和不确定的男孩也不太可能摄入推荐的每日水果摄入量。与异性恋女孩相比，双性恋女孩更有可能在上学日每天看电视≥3 小时，并且更有可能饮用含糖饮料（AOR 1.30，95%CI=1.18-1.43）。所有性少数青年的当前吸烟率都高于他们的异性恋同龄人。性少数女孩和双性恋男孩的肥胖率明显高于异性恋同龄人。这些发现可以为制定有针对性的健康促进计划提供信息，以降低性少数青年的肥胖风险。
