Physiologic changes of pregnancy may predispose females to develop sleep disordered breathing (SDB) or protect against it. Studies evaluating outcomes of SDB symptoms in pregnancy are scarce. The goal of this study is to evaluate the prevalence of SDB symptoms in pregnancy and their relationship with pregnancy and neonatal outcomes.

A cross-sectional survey of randomly selected immediate postpartum females was performed using the multivariable apnea prediction index. Record review including demographics and medical history was performed. Main outcome measures included pregnancy and neonatal outcomes.

1000 subjects were recruited. Mean age was 29.1±6.1 years. Factors used in the regression analysis included age, body mass index, diabetes, chronic hypertension, multifetal gestations, smoking and renal disease.

Snoring is present in 35.1% of subjects. Symptoms of SDB were associated with a higher likelihood of pregnancy-induced hypertension and preeclampsia (aOR 2.38, 1.4–4.1, CI 95%), gestational diabetes (aOR 2.1, 1.3–3.4) and unplanned Caesarian sections (aOR 3.80 2.2–6.7) after multivariable regression analysis. Gasping was likely associated with a higher likelihood of preterm delivery after adjusting for age and multifetal pregnancies (aOR 1.8, 1.1–3.2) but this association appeared to be mediated by preeclampsia.

Symptoms of SDB are common in pregnancy and associated with a higher likelihood of gestational hypertensive disorders, gestational diabetes and unplanned Caesarian sections.
