This effect has not been evaluated in morbid obesity (MO). We hypothesised that the metabolic profile is more impaired in MO patients with OSA than in those without, and investigated whether any specific metabolic dysfunction is related to OSA in MO.<\/jats:p><jats:p>A prospective multicentre cross-sectional study was conducted in consecutive subjects before bariatric surgery. OSA was defined as apnoea\/hypopnoea index (AHI) \u226515 by overnight polysomnography. Anthropometrical, blood pressure (BP) and fasting blood measurements were obtained the morning after. Metabolic syndrome (MetS) was defined according to National Cholesterol Education Program Adult Treatment Panel III modified criteria.<\/jats:p><jats:p>159 patients were studied: 72% were female and 72% had OSA. MetS prevalence was 70% in OSA<jats:italic>versus<\/jats:italic>36% in non-OSA (p&lt;0.001). As AHI severity increased, metabolic parameters progressively worsened, even in those without type 2 diabetes (DM2). AHI was independently associated with systolic and diastolic BP, triglycerides and the percentage of glycosylated haemoglobin (HbA1c) in the total sample, and with systolic BP, high-density lipoprotein cholesterol and HbA1c in those samples without DM2. OSA increased the adjusted odds ratio of having MetS by 2.8 (95% CI 1.3\u20136.2; p=0.009).<\/jats:p><jats:p>In MO, OSA is associated with major metabolic impairment caused by higher BP and poorer lipid and glucose control, independent of central obesity or DM2.<\/jats:p>","DOI":"10.1183\/09031936.00198810","type":"journal-article","created":{"date-parts":[[2011,5,27]],"date-time":"2011-05-27T03:06:48Z","timestamp":1306465608000},"page":"1089-1097","source":"Crossref","is-referenced-by-count":47,"title":["Obstructive sleep apnoea and metabolic impairment in severe obesity"],"prefix":"10.1183","volume":"38","author":[{"given":"M.","family":"Gasa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Salord","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.M.","family":"Fortuna","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Mayos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Vilarrasa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Dorca","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.M.","family":"Montserrat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.R.","family":"Bonsignore","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Monasterio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"81","published-online":{"date-parts":[[2011,5,26]]},"reference":[{"key":"2024102020410752000_38.5.1089.1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.109.192644"},{"key":"2024102020410752000_38.5.1089.2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.288.21.2709"},{"key":"2024102020410752000_38.5.1089.3","doi-asserted-by":"publisher","DOI":"10.2337\/diacare.28.7.1769"},{"key":"2024102020410752000_38.5.1089.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2008.05.010"},{"key":"2024102020410752000_38.5.1089.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.atherosclerosis.2009.10.045"},{"key":"2024102020410752000_38.5.1089.6","doi-asserted-by":"publisher","DOI":"10.1136\/pgmj.2008.078014"},{"key":"2024102020410752000_38.5.1089.7","doi-asserted-by":"publisher","DOI":"10.1016\/j.atherosclerosis.2009.08.016"},{"key":"2024102020410752000_38.5.1089.8","doi-asserted-by":"crossref","first-page":"1193","DOI":"10.1093\/sleep\/33.9.1193","article-title":"Consequences of comorbid sleep apnea in the metabolic syndrome\u2013implications for cardiovascular risk","volume":"33","author":"Trombetta","year":"2010","journal-title":"Sleep"},{"key":"2024102020410752000_38.5.1089.9","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00166808"},{"key":"2024102020410752000_38.5.1089.10","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00027406"},{"key":"2024102020410752000_38.5.1089.11","doi-asserted-by":"crossref","first-page":"289","DOI":"10.1093\/ilar.50.3.289","article-title":"Metabolic consequences of sleep-disordered breathing","volume":"50","author":"Jun","year":"2009","journal-title":"ILAR J"},{"key":"2024102020410752000_38.5.1089.12","doi-asserted-by":"publisher","DOI":"10.1513\/pats.200708-139MG"},{"key":"2024102020410752000_38.5.1089.13","doi-asserted-by":"publisher","DOI":"10.4065\/83.8.897"},{"key":"2024102020410752000_38.5.1089.14","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-009-9999-z"},{"key":"2024102020410752000_38.5.1089.15","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1381\/096089204772787248","article-title":"Evidence supporting routine polysomnography before bariatric surgery","volume":"14","author":"O'Keeffe","year":"2004","journal-title":"Obes Surg"},{"key":"2024102020410752000_38.5.1089.16","doi-asserted-by":"publisher","DOI":"10.1007\/s11695-009-9928-1"},{"key":"2024102020410752000_38.5.1089.17","first-page":"1040","article-title":"The 2007 GOLD Guidelines: a comprehensive care framework","volume":"54","author":"Gold","year":"2009","journal-title":"Respir Care"},{"key":"2024102020410752000_38.5.1089.18","doi-asserted-by":"publisher","DOI":"10.1249\/01.MSS.0000078924.61453.FB"},{"key":"2024102020410752000_38.5.1089.19","doi-asserted-by":"publisher","DOI":"10.1157\/13076402"},{"key":"2024102020410752000_38.5.1089.20","doi-asserted-by":"crossref","first-page":"667","DOI":"10.1093\/sleep\/22.5.667","article-title":"recommendations for syndrome definition and measurement techniques in clinical research.
