This systematic review and meta\u2010analysis determined the prevalence of OSA confirmed by polysomnography in cystic fibrosis and non\u2010cystic fibrosis bronchiectasis patients. A comprehensive search of MEDLINE, EMBASE and Cochrane databases through September 2025 identified observational studies reporting polysomnography\u2010confirmed OSA prevalence in adult bronchiectasis patients. Five studies encompassing 256 patients met inclusion criteria, with data extracted and quality assessed using the Newcastle\u2013Ottawa Scale. The pooled obstructive sleep apnea prevalence was 50.5% (95% confidence interval: 42.3%\u201358.9%) with low heterogeneity, ranging from 40.4% to 64.3% in cystic fibrosis patients and 40.8% to 55.8% in non\u2010cystic fibrosis bronchiectasis patients. Traditional risk factors including obesity and excessive daytime sleepiness showed weak associations, with a mean body mass index of 23.8\u201324.2\u2009kg\/m\n                    <jats:sup>2<\/jats:sup>\n                    . Male gender, longer disease duration, and corticosteroid use emerged as significant risk factors. Nocturnal hypoxemia independent of obstructive sleep apnea occurred in 16.7% of patients. Only 41% of diagnosed patients received positive airway pressure therapy. OSA affects approximately half of all bronchiectasis patients regardless of aetiology, substantially exceeding general population rates. The clinical presentation differs from classical OSA, with weaker associations with obesity and daytime sleepiness, suggesting distinct pathophysiological mechanisms. Systematic screening should be incorporated into bronchiectasis management, particularly for male patients with longer disease duration or corticosteroid use.\n                  <\/jats:p>","DOI":"10.1111\/jsr.70333","type":"journal-article","created":{"date-parts":[[2026,3,30]],"date-time":"2026-03-30T02:14:28Z","timestamp":1774836868000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Obstructive Sleep Apnea in Bronchiectasis: Prevalence, Risk Factors and Clinical Implications\u2014A Systematic Review and Meta\u2010Analysis"],"prefix":"10.1111","volume":"35","author":[{"given":"Narat","family":"Srivali","sequence":"first","affiliation":[{"name":"Division of Pulmonary, Allergy and Critical Care Medicine Duke University School of Medicine  Durham North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Federica","family":"De Giacomi","sequence":"additional","affiliation":[{"name":"Respiratory Unit, Cremona Hospital  Cremona Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,29]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/nu14061216"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2025.2680"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/ppul.26806"},{"issue":"2","key":"e_1_2_12_5_1","first-page":"243","article-title":"The Sympathetic Nervous System and Catecholamines Metabolism in Obstructive Sleep Apnoea","volume":"8","author":"Bisogni V.","year":"2016","journal-title":"Journal of Thoracic Disease"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.5152\/TurkThoracJ.2021.20194"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1183\/16000617.0049\u20102024"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.21037\/jtd\u2010cus\u20102020\u2010006"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.14\u20100500"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.4103\/lungindia.lungindia_241_17"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsmc.2024.02.002"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0185413"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.smrv.2018.08.009"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arbres.2023.07.002"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.1037\/1082-989X.11.2.193"},{"issue":"105","key":"e_1_2_12_16_1","first-page":"940","article-title":"Non\u2010CF Bronchiectasis: Orphan Disease No Longer","volume":"166","author":"Imam J.
