OBJECTIVE
The aim was to assess associations between lifestyle behaviors and obesity in a multinational study of children from 12 countries representing a wide range of human development.
METHODS
The sample included 6,025 children 9-11 years of age. Behavioral risk factors included nocturnal sleep duration, moderate to vigorous physical activity (MVPA), television viewing (TV time), and healthy and unhealthy diet pattern scores. Multilevel analyses were used to obtain odds ratios for obesity expressed per standard deviation of each behavioral risk factor.
RESULTS
The odds ratios (95% confidence intervals) for obesity from multilevel, multivariable models were 0.79 (0.71-0.90) for nocturnal sleep duration, 0.52 (0.45-0.60) for MVPA, 1.15 (1.05-1.27) for TV time, 1.08 (0.96-1.20) for healthy diet score, and 0.93 (0.83-1.04) for unhealthy diet score in boys and 0.71 (0.63-0.80) for nocturnal sleep duration, 0.43 (0.35-0.53) for MVPA, 1.07 (0.96-1.19) for TV time, 1.05 (0.93-1.19) for healthy diet score, and 0.96 (0.82-1.11) for unhealthy diet score in girls.
CONCLUSIONS
Behavioral risk factors are important correlates of obesity in children, particularly low MVPA, short sleep duration, and high TV viewing.
目的
在一项对来自12个国家、代表广泛人类发展水平的儿童进行的跨国研究中，评估生活方式行为与肥胖之间的关联。
方法
样本包括6025名9至11岁的儿童。行为风险因素包括夜间睡眠时间、中度至剧烈身体活动（MVPA）、看电视时间（电视时长）以及健康和不健康饮食模式得分。采用多水平分析来获取每个行为风险因素每增加一个标准差时肥胖的比值比。
结果
多水平多变量模型得出的男孩肥胖比值比（95%置信区间）为：夜间睡眠时间为0.79（0.71 - 0.90），MVPA为0.52（0.45 - 0.60），电视时长为1.15（1.05 - 1.27），健康饮食得分1.08（0.96 - 1.20），不健康饮食得分0.93（0.83 - 1.04）；女孩肥胖比值比为：夜间睡眠时间为0.71（0.63 - 0.80），MVPA为0.43（0.35 - 0.53），电视时长为1.07（0.96 - 1.19），健康饮食得分1.05（0.93 - 1.19），不健康饮食得分0.96（0.82 - 1.11）。
结论
行为风险因素是儿童肥胖的重要相关因素，尤其是低MVPA、短睡眠时间和高电视观看时长。
