White women had a later bedtime at 6-8 weeks compared to 6 months, but no significant change occurred for Black women. For the entire sample, average nighttime sleep duration increased from 385 min at 6-8 weeks to 404 min at 4 months postpartum. Percent sleep during the sleep interval and wake after sleep onset (WASO) improved by 6 and 9 months, respectively. However, average WASO remained &gt;45 min and sleep efficiency &lt;85 % at all timepoints for both Black and White women. Compared to White women, Black women had significantly shorter sleep duration (range: 40.6-59.9 min shorter across all timepoints, p &lt; 0.0001) and time in bed (range: 17.5-67.6 minutes shorter, p = 0.0046), and lower percent sleep (range: 0.7-1.2 % lower, p = 0.0407) and sleep efficiency (range: 2.6-5.7 % lower, p = 0.0005). Sociodemographic factors were associated with sleep outcomes in Black and White women while behavioral factors were associated with sleep outcomes in White women only.</p></div><div><h3>Conclusion</h3><p>While there were improvements in nighttime sleep duration and quality, sleep duration remained suboptimal, and quality remained poor throughout the first year postpartum. In this sample, differences existed in factors associated with sleep outcomes between Black and White women.</p></div>","PeriodicalId":74809,"journal":{"name":"Sleep epidemiology","volume":"4 ","pages":"Article 100096"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667343624000222/pdfft?md5=6462995d4600c6acc41392948c251f22&pid=1-s2.0-S2667343624000222-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142163487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
