Objective-To determine the prevalence and clinical and metabolic correlates of sleep disordered breathing (SDB) and excessive daytime sleepiness (EDS) in adolescent girls with polycystic ovarian syndrome (PCOS).Study design-Standardized questionnaires were administered to subjects with PCOS and age-, sex-, ethnicity-, and BMI Z-score-matched controls. Medical records were reviewed for anthropometric and metabolic data.Results-We studied 103 subjects with PCOS (16.9±1.5 years) and 90 controls (16.8±1.7 years). Compared with controls, girls with PCOS had a higher prevalence of SDB (45.6% vs. 27.8%, p=0.01) and EDS (54.4% vs.35.6%, p<0.01). Within PCOS, those with SDB had higher BMI Zscore (2.1±0.5 vs.1.7±0.6, p< 0.01), higher homeostatic model assessment (HOMA) (5.1±2.3 vs. 4.1±3.5, p<0.01), and higher prevalence of the metabolic syndrome (MetS) (42.6% vs. 16.1%, p=0.003), compared with those without SDB. Similarly, subjects with PCOS and EDS had higher BMI-Z score (2.0±0.6 vs.1.7±0.6, p=0.03), higher HOMA (5.1±2.9 vs.3.8±3.1, p=0.01), and higher rate of MetS (39.3% vs. 14.9% p<0.01), compared with those without EDS. MetS was independently associated with SDB (OR 3.2, CI-1.0-10.1) and EDS (OR 4.5, CI-1.2-16).Conclusions-SDB and EDS are highly prevalent in adolescent girls with PCOS compared with matched controls. The MetS is independently associated with SDB and EDS in this group. The preliminary results of this paper were presented at ATS 2010 International Meeting.Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication.

In recent years, PCOS has also been recognized to be associated with sleep disordered breathing (SDB) as well as excessive daytime sleepiness (EDS) [4,5]. In fact, a prospective case-control study, estimated that women with PCOS have a 30-fold higher prevalence of SDB than women in the general population [5]. The pathophysiological mechanisms leading to such high prevalence of SDB in PCOS have not yet been defined. However, possible causes include alterations in body fat composition due to excess androgen levels and/or the effects of metabolic syndrome [4,6], the later of which has been previously associated with increased risk of SDB in patients without PCOS [7,8]. Even though SDB is very prevalent in women with the disorder, the natural history of the disorder in adolescent girls and young women is unknown, mostly due to lack of knowledge about such an association.
