横跨几个国家的大量文献表明，产妇就业与儿童体重指数(BMI)之间存在正相关关系。较少的研究考察了父亲就业的作用。更重要的是，很少有经验性工作研究可能解释父母就业和儿童BMI之间关系的机制。我们的论文测试了孩子一生中母亲和配偶工作的累积经历与孩子13或14岁时的BMI、超重和肥胖之间的关系。我们进一步研究了几种可能解释这些联系的机制。我们使用了美国国家青年纵向调查(NLSY79)合并的母子档案中的数据，这些数据是关于出生在儿童肥胖症和母亲就业大幅增加时期的儿童的队列。我们发现，受过高等教育的母亲在孩子一生中工作的小时数与孩子13或14岁时的BMI和超重风险呈正向统计显著相关。另一方面，母亲配偶和伴侣的工作时间与这些结果没有显著关联。结果表明，对于受过高等教育的母亲的孩子来说，母亲的工作时间和孩子的体重指数之间的联系部分是通过看电视的时间来调节的。
A robust body of literature spanning several countries indicates a positive association between maternal employment and child body mass index (BMI). Fewer studies have examined the role of paternal employment. More importantly, little empirical work examines the mechanisms that might explain the relationships between parental employment and children’s BMI. Our paper tests the relationship between the cumulative experience of maternal and spouse employment over a child’s lifetime and that child’s BMI, overweight, and obesity at age 13 or 14. We further examine several mechanisms that may explain these associations. We use data from the U.S. National Longitudinal Survey of Youth (NLSY79) merged mother-child file on cohorts of children who were born during a period of dramatic increase in both childhood obesity and maternal employment. We find that the number of hours that highly-educated mothers work over her child’s lifetime is positively and statistically significantly associated with her child’s BMI and risk of overweight at ages 13 or 14. The work hours of mothers’ spouses and partners, on the other hand, are not significantly associated with these outcomes. Results suggest that, for children of highly-educated mothers, the association between maternal work hours and child BMI is partially mediated by television viewing time.
