Previous research shows that maternal employment is associated with higher children's body mass index (BMI). Using a large UK longitudinal birth cohort study of almost 20,000 children, we examine the effect of maternal employment during childhood (to age 14) on children's weight. We address the endogeneity of maternal employment by estimating household fixed effects models. We find that maternal employment has a positive effect on children's BMI and therefore on excess weight, and this is particularly the case for single mothers. We investigate potential pathways, including children's sedentary behavior and healthy eating behaviors, and find evidence of more sedentary behavior and poorer eating habits amongst children whose mothers are in employment. This is consistent with higher BMI levels amongst these children.
先前的研究表明,母亲就业与儿童较高的体重指数(BMI)相关。我们利用一项针对近20000名儿童的大型英国纵向出生队列研究,考察儿童期(至14岁)母亲就业对儿童体重的影响。我们通过估计家庭固定效应模型来解决母亲就业的内生性问题。我们发现,母亲就业对儿童的BMI有积极影响,因此对超重也有积极影响,单身母亲的情况尤其如此。我们研究了潜在的途径,包括儿童的久坐行为和健康饮食行为,发现在母亲就业的儿童中,有更多久坐行为和更差饮食习惯的证据。这与这些儿童较高的BMI水平相一致。
