Snoring and sleep position have been previously shown to change during pregnancy and these changes are associated in some studies with gestational diabetes and hypertension, pre-eclampsia, premature birth, and intrauterine growth restriction. Most of these studies have studied only high risk populations and been cross-sectional in nature, typically assessing snoring and sleep position in the 3rd trimester. To assess changes over time, we recruited 79 women ( 23 ± 7 weeks gestation) from a general prenatal clinic and contacted them monthly regarding snoring and sleep position. As of the writing of this abstract, 55 of these women had delivered. Snoring was more common during pregnancy than prior to pregnancy (P=0.002) as was sleeping on the side compared to the stomach (P<0.001). However, snoring frequency and sleep position during pregnancy did not vary over time within individuals or across observations. The highest snoring frequency category (> 3 times per week, present in 44% of the women) was present in all 7 women with gestational hypertension. Snoring remained a significant predictor of gestational hypertension after adjusting for the effect of obesity. Snoring was associated with cesarean delivery for arrested descent or failure to progress, but not with other labor characteristics. Snoring was not associated with gestational diabetes, small- or large- for gestation birth weight, or NICU admission. These results agree with previous research that snoring, as a surrogate for high risk of obstructive sleep apnea, is common during pregnancy and associated with gestational hypertension. Changes in snoring occur early in pregnancy and are stable in most women, implying the need for early assessment for presence of obstructive sleep apnea and potential treatment.
