背景：產後憂鬱症在臺灣具有極高的盛行率及影響力；而產婦比孕婦或婦女，更容易有睡眠障礙的情形，但此 兩項議題在國內極少被研究探討。 目的：本研究旨在探討產後憂鬱與睡眠品質的相關因素及兩者之相關性。 方法：採橫斷性研究設計，以新、北二市11家產後護理機構之187位產婦為研究對象，以中文版愛丁堡產後憂鬱 量表及產後睡眠品質量表進行資料收集。以描述性統計、t檢定、單因子變異數分析及皮爾森積差相關進行統計 分析。 結果：1.5.9%受試者有產後憂鬱現象（EPDS > 12），相關因素為年紀輕、初產婦、剖腹產、生產經驗很差、混 合哺餵及坐月子感受不好者。2.產後睡眠品質平均得分為17.15分（總分56分），相關因素為生產經驗很差、有生 理不適症狀、夜晚照顧嬰兒、坐月子感受不好者。3.產後憂鬱愈高者睡眠品質愈差（r = .41, p < .001）。 結論：宜重視產後憂鬱與睡眠品質的相關因素，以及產後憂鬱對睡眠品質的影響，以期能預防產後憂鬱的發生 與減少產後睡眠困擾。

Background: Although postpartum women are prone to have sleep disorders compared with pregnant or general women, and that postpartum depression is highly prevalent in Taiwan and has a substantial influence on Taiwanese women, these two topics have rarely been examined together in Taiwan. Objective: This study investigated the correlations between postpartum depression and sleep quality as well as their relating factors. Methods: This study adopted a cross-sectional study design. A total of 187 postpartum women were recruited from 11 postpartum care facilities in New Taipei City and Taipei City. Data were collected using the Chinese version of the Edinburgh postnatal depression scale (EPDS) and postpartum sleep quality scale. For data analysis, descriptive statistics, t test, one-way ANOVA, and Pearson correlation analysis were conducted. Results: The results showed that first, 5.9% of participants had postpartum depression (EPDS score of >12), which was correlated with young age, primipara, caesarean delivery, unpleasant birthing experience, mixed feeding, and discomfort in postpartum recovery (i.e., the Chinese custom of “sitting the month”). Second, the mean postpartum sleep quality scale score was 17.15 (total score: 56), and was correlated with unpleasant birthing experience, physiological discomfort, caregiving at night, and discomfort in sitting the month. Women with postpartum depression also had poorer sleep quality (r = .41, p < .001). Conclusion: Paying attention to factors related to postpartum depression and sleep quality, and the effect of postpartum depression on sleep quality facilitates reducing the incidence of postpartum depression and mitigating postpartum sleep-related problems.
