No previous study reported an association of paternal involvement in childcare and housework with maternal physical punishment.
Using data from the Japanese Longitudinal Survey of Newborns in the 21st century (N = 38,554), we analyzed responses about fathers' involvement in childcare and housework at 6 months and mothers' spanking of children at 3.5 years. Fathers' involvement in childcare and housework was scored and categorized into quartiles. Spanking frequency was asked in the "often", "sometimes", or "not at all" categories. Multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the mothers' often spanking children were computed for the fathers' involvement in childcare and housework. We also stratified the association by fathers' working hours (40-49, 50-59, or ≥60 hours/week).
Among the 16,373 respondents, the proportion of mothers who often spanked their children was 4.8%. Compared with the lowest quartile, a higher frequency of paternal involvement in housework was associated with a lower risk of spanking children (P = 0.001). Adjustment for covariates attenuated the association, but significant association was observed in the 3 quartile of paternal involvement in housework (OR 0.77; 95% CI, 0.62-0.96). When the fathers worked fewer than 50 hours a week, a significant negative association was observed between the fathers' frequency of childcare and the likeliness of the mothers' spanking their children (P = 0.02).
The fathers' active involvement in childcare and housework could reduce the mothers' physical punishment for their children.
此前尚无研究报道父亲参与育儿和家务劳动与母亲体罚之间的关联。
利用21世纪日本新生儿纵向调查的数据（N = 38,554），我们分析了关于父亲在孩子6个月时参与育儿和家务劳动以及母亲在孩子3.5岁时对其进行打屁股惩罚的回答。对父亲参与育儿和家务劳动进行评分并分为四分位数。打屁股频率通过“经常”“有时”或“从不”类别来询问。计算父亲参与育儿和家务劳动情况下母亲经常打孩子的多变量调整优势比（OR）和95%置信区间（CI）。我们还按父亲的工作时长（40 - 49、50 - 59或≥60小时/周）对这种关联进行分层。
在16,373名受访者中，经常打孩子的母亲比例为4.8%。与最低四分位数相比，父亲参与家务劳动的频率越高，打孩子的风险越低（P = 0.001）。对协变量进行调整后减弱了这种关联，但在父亲参与家务劳动的第3四分位数中仍观察到显著关联（OR 0.77；95% CI，0.62 - 0.96）。当父亲每周工作少于50小时时，观察到父亲参与育儿的频率与母亲打孩子的可能性之间存在显著负相关（P = 0.02）。
父亲积极参与育儿和家务劳动可减少母亲对孩子的体罚。
