A third of Latino adults reported moderate to a lot of trouble sleeping three or more nights per week. The logistic regression results reveal that controlling for a comprehensive set of covariates, Latinos who were “a lot” worried about deportation or who know people who have been deported/detained were significantly more likely to report that they had trouble sleeping.</div></div><div><h3>Conclusions</h3><div>The results suggest that the US deportation system presents a unique source of stress and rumination that negatively impacts Latino sleep. These findings advance social scientific knowledge and the socio-ecological framework regarding how US policy priorities of deporting and detaining immigrants can potentially alter the sleeping patterns of a large segment of Americans, even among those not directly targeted for removal from the country.</div></div>","PeriodicalId":48545,"journal":{"name":"Sleep Health","volume":"11 2","pages":"Pages 133-139"},"PeriodicalIF":3.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143504457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
