Women's lives are marked by complex work and family routines - routines that have implications for their children's health. Prior research suggests a link between mothers' work hours and their children's weight, but few studies investigate the child health implications of increasingly common work arrangements, such as telecommuting and flexible work schedules. We examine whether changes in mothers' work arrangements are associated with changes in adolescents' weight, physical activity, and sedentary behavior using longitudinal data and fixed effects models to better account for mothers' social selection in to different work arrangements and children's underlying preferences. With data from the National Longitudinal Study of Adolescent to Adult Health ( 10,518), we find that changes in mothers' work arrangements are not significantly associated with adolescents' weight gain or physical activity but are significantly associated with adolescents' sedentary behavior. Adolescents' sedentary behavior declines when mothers become more available after school and increases when mothers work more hours or become unemployed. In sum, after accounting for unobserved, stable traits, including mothers' selection into jobs with more or less flexibility, mothers' work arrangements are most strongly associated with adolescents' sedentary behavior.
女性的生活被复杂的工作和家庭日常所标记——这些日常对她们孩子的健康有影响。先前的研究表明母亲的工作时长与其孩子的体重之间存在联系，但很少有研究调查日益普遍的工作安排对孩子健康的影响，比如远程办公和灵活的工作时间表。我们使用纵向数据和固定效应模型来更好地考虑母亲对不同工作安排的社会选择以及孩子的潜在偏好，以此研究母亲工作安排的变化是否与青少年的体重、身体活动和久坐行为的变化相关。利用来自全国青少年健康纵向研究的数据（10518人），我们发现母亲工作安排的变化与青少年体重增加或身体活动并无显著关联，但与青少年的久坐行为显著相关。当母亲放学后更有空时，青少年的久坐行为会减少；而当母亲工作时间更长或失业时，青少年的久坐行为会增加。总之，在考虑了包括母亲对灵活性不同的工作的选择在内的未观察到的稳定特征后，母亲的工作安排与青少年的久坐行为关联最为紧密。
