Abstract

Study Objectives: In this systematic review and meta-analysis, we aimed to examine the relationship between obstructive sleep apnea (OSA) and metabolic abnormalities in women with polycystic ovary syndrome (PCOS). Methods: Electronic databases (Medline, Embase, Cinahl, PsycInfo, Scopus, Web of Science, Opengrey, and CENTRAL), conference abstracts, and reference lists of relevant articles were searched. No restriction was applied for language or publication status. Results: Six studies involving 252 participants were included. Women with PCOS and OSA had significantly higher body mass index (mean difference [MD]: 6.01 kg/m2, 95% confidence intervals [CI]: 4.69-7.33), waist circumference (MD: 10.93 cm, 95% CI: 8.03-13.83), insulin resistance, systolic and diastolic blood pressure, and worse lipids' profile and impaired glucose regulation compared with women with PCOS without OSA. Most studies did not adjust for weight in their between-groups analysis. Total and free testosterone levels were not significantly different between the two groups. The majority of studies were found to be at high risk of selection bias, did not account for important confounders, were conducted in one country (United States), and used different methodologies to assess testosterone levels (preventing a meta-analysis for this specific outcome). Conclusions: OSA is associated with obesity and worse metabolic profiles in women with PCOS. However, whether the effects of OSA are independent of obesity remain unclear. As OSA is a treatable condition, research focused on the independent effects of OSA on key clinical outcomes in women with PCOS, including fertility, psychological health, type 2 diabetes, and cardiovascular risk, is lacking and needed.

  • Compared to previous meta-analyses, the present study showed relatively higher pooled OSA prevalence (37.0% vs 20.8-35.0%) and higher risk of OSAS (OR 9.52 vs ORs 2.86-8.30) in women with PCOS relative to without PCOS.

    “Compared to previous meta-analyses, the present study showed relatively higher pooled OSA prevalence (37.0% vs. 20.8-35.0%) and higher risk of OSAS (OR: 9.52 vs. ORs: 2.86-8.30) in women with PCOS relative to without PCOS (14, 22, 26).”

    The Discussion (p. 7) says several studies suggest OSA is more prevalent in women with PCOS than in women without PCOS. It does not report the cited prevalence range of 20.8–35.0% or odds-ratio range of 2.86–8.30; this review primarily compares metabolic outcomes among women with PCOS with and without OSA.

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.
