The demand on Japanese women to fulfill their dual roles as mothers and labor force participants leads to a subsequent reduction of their employment hours, switching of occupations, or quitting the labor force. This study aims to examine paternal factors associated with mothers' employment status 18 months after childbirth.
We used data from the 2010 cohort of the Longitudinal Survey of Newborns conducted in Japan. We restricted our analysis to 10 712 mothers who had full-time employment 1 year before childbirth. A logistic regression analysis was conducted to assess paternal factors associated with mothers' employment after childbirth.
One-third of the mothers with full-time employment before childbirth were not working full-time 18 months after delivery. We found that high childcare involvement (score 13-18) of fathers (OR, 1.20; 95% CI, 1.01-1.43) and fathers with part-time employment (OR, 1.59; 95% CI, 1.12-2.26) were associated with higher odds of mothers' full-time employment. Fathers' weekly work of ≥60 h (OR, 0.79; 95% CI, 0.71-0.88) and higher annual income decreased the odds ratios by over 20%.
Fathers' work arrangements and involvement in childcare play a key role in helping mothers resume employment postchildbirth.
日本女性既要履行母亲的角色，又要作为劳动力参与其中，这导致她们随后减少了工作时间、转换了职业，或退出了劳动力市场。本研究旨在探讨与母亲产后就业状况相关的父亲因素。
我们使用了日本 2010 年新生儿纵向调查的队列数据。我们将分析仅限于分娩前 1 年有全职工作的 10712 名母亲。采用逻辑回归分析评估与产后母亲就业相关的父亲因素。
分娩前有全职工作的母亲中有三分之一在分娩后 18 个月没有全职工作。我们发现父亲较高的育儿参与度（评分 13-18）（比值比 [OR]，1.20；95%置信区间 [CI]，1.01-1.43）和父亲从事兼职工作（OR，1.59；95%CI，1.12-2.26）与母亲全职就业的可能性更高相关。父亲每周工作时间≥60 小时（OR，0.79；95%CI，0.71-0.88）和较高的年收入使比值比降低了 20%以上。
父亲的工作安排和参与育儿在帮助母亲产后重返工作岗位方面发挥了关键作用。
