Several studies have used latent class analyses to explore obesogenic behaviors and substance use in adolescents independently. We explored a variety of health risks jointly to identify distinct patterns of risk behaviors among adolescents.
Latent class models were estimated using Youth Risk Behavior Surveillance System (YRBSS) 2011 data. Behaviors in the models included substance use, physical fights, physical activity (PA), sedentary activity, sleep, fruit and vegetables (F&V) consumption, and weight-related variables. Models were estimated separately by sex. Constrained and unconstrained models were computed for race. Age and perceived and calculated weight status were compared among emergent latent classes using latent multinomial logistic regressions.
Four and 5 latent class solutions emerged for boys and girls, respectively. Healthy, sedentary, and physically active (PA) groups were common in both boys and girls. The sample of boys also included a health risk behavior (HRB)/PA group and the sample of girls included HRB and HRB/F&V groups.
The results confirm that obesogenic and HRBs should be conceptualized as combined patterns of risk. Health education programming in schools should adopt a multiple health behavior approach to target the continuum of risks adolescents engage in simultaneously.
多项研究已使用潜在类别分析来单独探究青少年的致胖行为和物质使用情况。我们联合探究了多种健康风险,以识别青少年中不同的风险行为模式。
使用2011年青少年风险行为监测系统(YRBSS)数据估计潜在类别模型。模型中的行为包括物质使用、肢体冲突、体育活动(PA)、久坐活动、睡眠、水果和蔬菜(F&V)消费以及与体重相关的变量。模型按性别分别估计。针对种族计算了受限和无约束模型。使用潜在多项逻辑回归在新出现的潜在类别中比较年龄以及感知和计算出的体重状况。
分别为男孩和女孩得出了4种和5种潜在类别解决方案。健康、久坐和体育活动(PA)组在男孩和女孩中都很常见。男孩样本还包括一个健康风险行为(HRB)/PA组,女孩样本包括HRB组和HRB/F&V组。
结果证实,致胖行为和健康风险行为应被概念化为综合的风险模式。学校中的健康教育计划应采用多种健康行为方法,以针对青少年同时面临的一系列风险。
