Despite the fact that more than 90% of mothers in Japan prefer breastfeeding, the breastfeeding rate at 6 months postpartum is as low as approximately 35%. Postpartum depression and bonding disorder are recognized as factors associated with discontinuation of breastfeeding. However, these factors remain controversial. The purpose of the present study was to clarify the effect of postpartum depressive symptoms and bonding on the feeding pattern from 1- to 5-month postpartum. A longitudinal study was conducted at 1- and at 5-month postpartum, in 405 mothers who attended health check at three hospitals in the Tokyo metropolitan area at 1-month postpartum, and completed longitudinal questionnaires. A high proportion of breastfeeding mothers at 1 month postpartum had Edinburgh Postpartum Depression Scale (EPDS) score of ≥ 9 at 5 months postpartum (p=0.01), and these mothers changed to formula milk-based feeding at 5-month postpartum, when compared with those of the breastfeeding-based group at both 1- and 5-month postpartum,. The appearance of depressive symptoms seems to promote discontinuation of breastfeeding at 5-month postpartum.
尽管超过 90%的日本母亲更喜欢母乳喂养，但产后 6 个月的母乳喂养率却低至约 35%。产后抑郁症和母子联系障碍被认为是与停止母乳喂养相关的因素。然而，这些因素仍存在争议。本研究旨在阐明产后抑郁症状和母子联系对 1 至 5 个月产后喂养模式的影响。在东京都地区的 3 家医院，对 405 名在产后 1 个月接受健康检查并完成纵向问卷调查的母亲进行了纵向研究，在产后 1 个月和 5 个月进行了调查。产后 1 个月时，相当一部分母乳喂养的母亲在产后 5 个月时的爱丁堡产后抑郁量表（EPDS）评分为≥9（p=0.01），与产后 1 个月和 5 个月均为母乳喂养组的母亲相比，这些母亲在产后 5 个月时改为配方奶喂养。抑郁症状的出现似乎会促使母亲在产后 5 个月停止母乳喂养。
