ABSTRACT

This study examined whether previous findings linking maternal work hours to obesity among children generalised to Asian populations. Using a nationally representative sample of Korean middle school students and their parents (N = 1,873), ordinary least squares regression and logistic regression models assessed the association between maternal work hours and adolescents’ body mass index (BMI), overweight, and obesity. There were no significant associations between mothers’ weekly work hours and adolescents’ BMI (raw score, z-score, and percentile), overweight and obesity. These null associations were robust across different specifications for maternal employment, the proposed mediators, and outcome variables. Although longer maternal work hours were associated with adolescents’ longer unsupervised time, more sedentary behaviours (TV/Video/DVD viewing and electronic game playing), and less physical activity, this did not lead to an increase in the likelihood of being overweight and obese.

摘要

这项研究检查了以前的发现是否将母亲工作时间与肥胖症联系起来，这些儿童普遍存在于亚洲人口中。使用全国代表性的韩国中学生及其父母的样本（N = 1873），普通最小二乘回归和逻辑回归模型评估了母亲工作时间与青少年体重指数（BMI），超重和肥胖之间的关联。母亲的每周工作时间与青少年的BMI（原始得分，z得分和百分位数），超重和肥胖之间没有显着关联。这些零关联在孕产妇就业，拟议的调解人和结果变量的不同规范方面均很强健。尽管更长的产妇工作时间与青少年更长的无监督时间，更多的久坐行为（观看电视/视频/ DVD和玩电子游戏）以及较少的体育锻炼有关，但这并未导致超重和肥胖的可能性增加。
