Pregnancy brings physical and hormonal changes and sleep is impaired by heartburn, cramps, frequent urination, fetal movements... Snoring is commonly observed in pregnant women at the end of the second and third trimester. Snoring can be a manifestation of OSAS. It has been shown that the apnea-hypopnea index (AHI) increases during pregnancy, at the third quarter. Physiological changes associated with pregnancy increase the risk of OSAS. In pregnant women, sleep deprivation leads to increased risk of gestational diabetes, high blood pressure, preeclampsia and antenatal depression, but also a risk of premature delivery or having a child with a delay in growth.~Finally, the exact prevalence of sleep-disordered breathing in pregnant women is not known. The results of a analysis of a small cohort of 105 pregnant women adjusted to body mass index estimate a prevalence of 8.4% in first quarter and 19.7% in the third quarter.~In this context, this study proposes to assess the prevalence of sleep-disordered breathing in pregnant women of the Private Hospital of the Loire and to identify the risks associated with these disorders by systematically proposing a polysomnography.
