Associations between sleep duration (\u2264 6 h, &amp;gt; 6 to &amp;lt; 9 h, \u2265 9 h), sleep disorders, and OAB risk were assessed using multivariable logistic regression, restricted cubic splines (RCS), and smooth curve fitting, adjusting for demographic, socioeconomic, lifestyle, and health-related covariates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A significant non-linear, U-shaped relationship between sleep duration and OAB risk was observed. Compared to individuals with a sleep duration of 6\u20139 h, those with short sleep duration (\u2264 6 h) had a slightly lower risk of OAB (OR = 0.94), while those with long sleep duration (\u2265 9 h) had a significantly higher risk (OR = 2.54). Self-reported sleep disorders independently elevated the risk of OAB (OR = 1.46). RCS analysis identified 6 h of sleep as a critical inflection point.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study reveals a U-shaped relationship between sleep duration and the risk of overactive bladder (OAB), with both short (\u2264 6 h) and long (\u2265 9 h) sleep durations increasing OAB risk. These findings highlight the importance of sleep management in OAB care. Behavioral interventions, including sleep hygiene education and bladder training, may help mitigate symptoms and improve patient outcomes.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fmed.2025.1612280","type":"journal-article","created":{"date-parts":[[2025,9,18]],"date-time":"2025-09-18T05:31:23Z","timestamp":1758173483000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Sleep matters: the U-shaped relationship between sleep duration and overactive bladder in U.S. adults"],"prefix":"10.3389","volume":"12","author":[{"given":"Ciyi","family":"Guan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinhua","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinjiao","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junjun","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haiyuan","family":"Song","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,9,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"37","DOI":"10.1016\/S0090-4295(02)02243-4","article-title":"The standardisation of terminology in lower urinary tract function: report from the standardisation sub-committee of the International continence society.","volume":"61","author":"Abrams","year":"2003","journal-title":"Urology."},{"key":"B2","doi-asserted-by":"publisher","first-page":"1306","DOI":"10.1016\/j.eururo.2006.09.019","article-title":"Population-based survey of urinary incontinence, overactive bladder, and other lower urinary tract symptoms in five countries: results of the EPIC study.","volume":"50","author":"Irwin","year":"2006","journal-title":"Eur Urol."},{"key":"B3","doi-asserted-by":"publisher","first-page":"49","DOI":"10.1016\/j.eururo.2022.01.045","article-title":"European association of urology guidelines on the diagnosis and management of female non-neurogenic lower urinary tract symptoms.
