Exposure to violence may be associated with increased risk for obesogenic behavior among adolescents but studies providing a global perspective are lacking. The aim of this work was to assess the relationship between violence and obesogenic behaviors among young adolescents from 62 countries. Cross-sectional data from the Global School-based Student Health Survey 2009-2016 were analyzed. Information on violence (intentional injury, physical attack, physical fight) and obesogenic behavior (anxiety-induced sleep problems, low physical activity, sedentary behavior, fast-food consumption, carbonated soft-drink consumption) were self-reported. Associations were analyzed using meta-analysis based on country-wise multivariable logistic regression analyses. A total of 165,380 adolescents aged 12-15 years [mean (SD) age 13.8 (1.0) years; 50.9% boys] were included in the analysis. All types of violence were positively associated with higher odds for all types of obesogenic behavior with the exception of low physical activity. Associations were particularly pronounced for anxiety-induced insomnia. In contrast, intentional injury (OR = 0.72; 95%CI = 0.64-0.81) and physical fight (OR = 0.90; 95%CI = 0.86-0.95) were associated with lower odds for low physical activity. In this large global sample of adolescents, exposure to violence was associated with all obesogenic behaviors apart from low physical activity. Multidimensional government programs and policies addressing exposure to violence among young adolescents may lead to reduction in obesogenic behavior and hence curtail the global obesity epidemic.
遭受暴力可能与青少年发生致胖行为的风险增加有关，但缺乏提供全球视角的研究。这项工作的目的是评估62个国家青少年中暴力与致胖行为之间的关系。对2009 - 2016年全球基于学校的学生健康调查的横断面数据进行了分析。暴力（故意伤害、身体攻击、打架）和致胖行为（焦虑引起的睡眠问题、低体力活动、久坐行为、快餐消费、碳酸软饮料消费）的信息均为自我报告。基于各国多变量逻辑回归分析，使用荟萃分析对关联进行了分析。共有165380名12 - 15岁的青少年[平均（标准差）年龄13.8（1.0）岁；50.9%为男孩]纳入分析。除低体力活动外，所有类型的暴力与所有类型的致胖行为的较高几率均呈正相关。焦虑引起的失眠的关联尤为明显。相比之下，故意伤害（比值比=0.72；95%置信区间=0.64 - 0.81）和打架（比值比=0.90；95%置信区间=0.86 - 0.95）与低体力活动的较低几率相关。在这个全球范围内的大量青少年样本中，遭受暴力与除低体力活动外的所有致胖行为有关。针对青少年遭受暴力问题的多维政府计划和政策可能会减少致胖行为，从而遏制全球肥胖流行。
