This study used data the Youth Risk Behavior Surveillance System ( = 7,088) to examine factors associated with the odds of overweight/obesity. Overweight/obese was defined as a body mass index ≥85th percentile, based on age- and sex-specific growth charts. Participants were categorized into meeting/not meeting guidelines for: sleep, moderate-to-vigorous PA (MVPA), muscle strengthening PA, screen time, breakfast eating, fruit and vegetable consumption, and soda and milk consumption. Logistic regression analyses determined whether meeting guidelines for each health behavior was associated with the odds of students having overweight/obesity in the total group and stratified by sex. Meeting MVPA guidelines was the only behavior associated with having a lower odds of overweight/obesity in both sexes. For females, meeting recommendations for breakfast eating and strength training were also associated with lower odds of having overweight/obesity, whereas for boys, getting the recommended amount of sleep was associated with having lower odds of overweight/obesity. Interventions to reduce the prevalence of overweight/obesity in youth should be implemented inside and outside of the school environment and should include components addressing physical activity, diet, and sleep. Such interventions should address barriers to healthy behaviors that are unique to adolescents already affected by overweight/obesity.
本研究使用了青少年风险行为监测系统的数据（n = 7,088）来检验与超重/肥胖几率相关的因素。根据特定年龄和性别的生长图表，超重/肥胖被定义为体重指数≥第85百分位数。参与者被分类为是否符合以下方面的指南：睡眠、中度至剧烈身体活动（MVPA）、肌肉强化身体活动、屏幕使用时间、早餐食用、水果和蔬菜消费以及汽水和牛奶消费。逻辑回归分析确定了符合每项健康行为指南是否与全组及按性别分层的学生超重/肥胖几率相关。符合MVPA指南是唯一与男女超重/肥胖几率较低相关的行为。对于女性，符合早餐食用和力量训练建议也与超重/肥胖几率较低相关，而对于男孩，获得推荐的睡眠时间与超重/肥胖几率较低相关。应在学校环境内外实施干预措施以降低青少年超重/肥胖的患病率，这些措施应包括涉及身体活动、饮食和睡眠的内容。此类干预措施应解决已受超重/肥胖影响的青少年特有的健康行为障碍。
