Abstract

CONTEXT: Insulin resistance, impaired glucose tolerance, and type 2 diabetes are common in women with polycystic ovary syndrome (PCOS). Obstructive sleep apnea (OSA) has been linked to metabolic dysfunction. We studied women with and without PCOS to determine the extent to which OSA is responsible for insulin resistance and glucose intolerance in PCOS. METHODS: In a prospective design, 52 women with PCOS and 21 women without PCOS of similar age and body mass index had an overnight polysomnogram and a 75-g oral glucose tolerance test. RESULTS: Twenty-nine women (56%) with PCOS had OSA compared with four controls (19%) (adjusted odds ratio 7.1; 95% confidence interval, 1.7-45.7; P = 0.01). PCOS women with OSA were more insulin resistant than those without OSA [homeostasis model assessment (HOMA) index 5.7 +/- 0.4 vs. 3.5 +/- 0.4; P = 0.006] after controlling for age, body mass index, and ethnicity. Impaired glucose tolerance was found in 16 of 29 (55%) PCOS women with OSA and only six of 23 (26%) of those without OSA (unadjusted P = 0.049). Insulin resistance and glucose intolerance were highly correlated with the presence and severity of OSA. Among PCOS women with normal glucose tolerance, the presence of OSA was associated with a nearly 2-fold higher fasting insulin level and HOMA index. The severity of OSA was a highly significant predictor of the fasting concentrations of glucose and insulin as well as the 2-h glucose concentration and HOMA index. CONCLUSIONS: OSA is a highly prevalent and important determinant of insulin resistance, glucose intolerance, and type 2 diabetes in PCOS.

  • The present meta-analysis reported, for the first time, a ~5-fold higher effect estimate for AHI≥5 with symptoms compared to AHI≥5 only outcomes among individuals with PCOS (OR 17.95 vs OR 3.90).

    “The present meta-analysis reported, for the first time, a ~5-fold higher effect estimate for AHI≥5 with symptoms compared to AHI≥5 only outcomes among individuals with PCOS (OR: 17.95 vs. OR: 3.90) (15, 17–21, 40).”

    The Polysomnography section defines OSA as AHI ≥5 without a symptom requirement. The Results report higher odds of OSA in women with PCOS than in controls (OR 7.7), so this study is relevant to the AHI≥5-only outcome. It does not report the meta-analysis’s comparison with a symptomatic outcome or its ORs of 17.95 and 3.90 (pages not available in our copy). (LLM, conf=0.88)

  • Past cross-sectional studies have shown that obstructive sleep apnea syndrome (OSAS) is highly prevalent in women with polycystic ovary syndrome (PCOS) compared with the general population of reproductive-aged women (17-75% vs. 9-28%).

    “Past cross-sectional studies have shown that OSAS is highly prevalent in women with PCOS (15–19) compared with the general population of reproductive-aged women (17-75% vs. 9-28%) (9, 10), with lower rates in adolescents with PCOS (0-57%) (20, 21).”
  • All eight included studies employed polysomnography (PSG) to measure obstructive sleep apnea (OSA).

    “All eight studies employed PSG to measure OSAS (as this was an inclusion criterion) (15–21, 40), five of which also assessed the presence of other OSAS-related symptoms such as excessive daytime sleepiness (15, 16, 18, 19, 21).”
  • Only five of the eight included studies adjusted or matched their control group by age, body mass index (BMI) and/or ethnicity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
