Article Title: Snoring during pregnancy and delivery outcomes: a cohort study
Abstract: STUDY OBJECTIVE: This cohort study examined the impact of maternal snoring on key delivery outcomes such as mode of delivery, infant birth centile, and small-for-gestational age. DESIGN: Cohort study. SETTING: A large tertiary medical center. PATIENTS OR PARTICIPANTS: Pregnant women in their third trimester were recruited between March 2007 and December 2010. MEASUREMENTS AND RESULTS: Women were screened for habitual snoring, as a known marker for sleep disordered breathing. Outcome data were obtained from medical records following delivery and birth centiles were calculated. Of 1,673 women, a total of 35% reported habitual snoring (26% with pregnancy-onset snoring and 9% with chronic snoring). After adjusting for confounders, chronic snoring was associated with small-forgestational age (OR 1.65, 95%CI 1.02-2.66, P = 0.041) and elective cesarean delivery (OR 2.25, 95%CI 1.22-4.18, P = 0.008). Pregnancy-onset snoring was associated with emergency cesarean delivery (OR 1.68, 95%CI 1.22-2.30, P = 0.001). CONCLUSION: Maternal snoring during pregnancy is a risk factor for adverse delivery outcomes including cesarean delivery and small-for-gestational age. Screening pregnant women for symptoms of SDB may provide an early opportunity to identify women at risk of poor delivery outcomes. CLINICAL TRIALS REGISTRATION: IDENTIFIER: NCT01030003.
