Methods: We conducted a retrospective analysis of 1,567 adults (1,173 men and 394 women) at the Sleep Center of Zhongda Hospital, Southeast University. Participants were categorized into mild (apnea-hypopnea index [AHI] 5\u201314), moderate (AHI 15\u201329), severe (AHI \u226530) OSA groups, and healthy controls. Data included demographic characteristics, hematological profiles, metabolic panels, thyroid function tests, and comorbidity prevalence. Results: Females with OSA were significantly older than males (p &lt; 0.001). Males had higher rates of traditional risk factors like smoking, alcohol use, and loud snoring (p &lt; 0.005), while females reported more insomnia. Hematologically, males with OSA showed progressively increasing red blood cell counts, hematocrit, monocyte counts, and systemic inflammation with disease severity (p &lt; 0.01). Metabolically, males exhibited more pronounced dyslipidemia, higher glycosylated hemoglobin, and uric acid levels in severe OSA (p &lt; 0.05). In contrast, females demonstrated significant alterations in thyroid hormones (free tri-iodothyronine, free thyroxine) with increasing OSA severity (p &lt; 0.01). Conclusions: OSA shows significant sex dimorphism. Men are characterized by \u201cmetabolic disorders, aggravated inflammation, high severity of OSA.\u201d Women are characterized by \u201catypical symptoms, advanced age, thyroid abnormalities.\u201d These findings underscore the critical necessity for gender-tailored approaches in OSA screening, diagnosis, and therapeutic management.<\/jats:p>","DOI":"10.1159\/000551587","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T17:01:04Z","timestamp":1773939664000},"page":"122-129","source":"Crossref","is-referenced-by-count":1,"title":["Sex-Specific Phenotypic Characteristics in Obstructive Sleep Apnea: A Comprehensive Analysis of Anthropometric, Hematological, and Metabolic Profiles Stratified by Disease Severity"],"prefix":"10.1159","volume":"89","author":[{"given":"Hui","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junqian","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zihan","family":"Yao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyuan","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoli","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yijing","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,3,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.5664\/jcsm.11866"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/S2213-2600(19)30198-5"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1038\/nrdp.2015.15"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1186\/s12890-015-0102-3"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1513\/pats.200709-155MG"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1378\/chest.07-0828"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.2147\/NSS.S515819"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.sleep.2023.01.027"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kws342"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-021-85558-y"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.smrv.2017.03.003"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.157.1.9706079"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1183\/16000617.0030-2019"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1002\/ajh.26992"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.5664\/jcsm.3070"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.163.1.2001008"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/zsy236"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1016\/j.beem.2010.07.005"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0012065"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1111\/cen.14573"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.2147\/NSS.S475717"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.00925.2023"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.3390\/ijms25063243"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.5603\/EP.a2020.0037"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1097\/aia.0000000000000360"}],"container-title":["European Neurology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000551587","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T16:01:14Z","timestamp":1784044874000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000551587"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,19]]},"references-count":25,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,7,14]]},"published-print":{"date-parts":[[2026,8,5]]}},"URL":"https:\/\/doi.org\/10.1159\/000551587","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.31812058","asserted-by":"subject"}]},"ISSN":["0014-3022","1421-9913"],"issn-type":[{"value":"0014-3022","type":"print"},{"value":"1421-9913","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,3,19]]}}}
