Sleep and obstructive sleep apnea in women with infertility.

PURPOSE

Obstructive sleep apnea (OSA) is associated with polycystic ovarian syndrome (PCOS), a common cause of infertility. Understanding predictors and outcomes of OSA in women with infertility may guide treatment.

METHODS

A descriptive cross-sectional survey was performed to assess OSA in women presenting to an infertility clinic using validated sleep questionnaires to assess sleep and fertility outcomes. An Infertile-C group (controls with male or tubal factors) and an Infertile-S group (unknown/other infertile causes) were analyzed to assess OSA risk and other sleep disorders (e.g., restless legs syndrome (RLS) and insomnia) with fertility outcomes (time to pregnancy, PCOS, irregular menstruation, and miscarriage).

RESULTS

In 258 women, occurrences of OSA diagnosis (6%) and RLS (10%) were reported similar to women of child-bearing age in the general population. PCOS was unassociated with OSA risk. Predictors of OSA risk were BMI, insomnia symptoms, and sleep aid use. Obese women with high OSA risk were more likely to have other comorbidities (e.g., depression). In adjusted models, prior clinical OSA diagnosis was associated with miscarriage (odds ratio: 6.17 (1.24, 30.62), p = 0.026). RLS was associated with irregular menstruation (odds ratio: 3.73 (1.21, 11.53), p = 0.022).

CONCLUSIONS

Similar to other populations, women with infertility and OSA risk have more health comorbidities and higher BMI and may present with insomnia symptoms. While the data are limited, this study supports the potential associations of OSA and miscarriage. Further work is needed to evaluate OSA in female infertility.
