Objectives/Background: Snoring is a hallmark of Sleep Disordered Breathing (SDB) and is seen more often in pregnancy. This study was conducted to determine the frequency of snoring in pregnancy-induced hypertension and to observe its impact on feto-maternal outcomes.
Participants/Methods: Sixty-five women with preeclampsia and gestational hypertension comprised the study group, whereas 85 normotensive, age, and gestation matched women were the controls. All the subjects were questioned about habitual snoring and they were followed to study their feto-maternal outcomes.
Results and Conclusions: Snoring was seen more frequently in the cases (OR 16.9, 95% CI 6.8-41.7) as compared to controls even after controlling for BMI. The severity of hypertension was more in snorers (p=0.021). The adverse pregnancy outcomes were more severe in the snorers in the cases as well as the controls. The fetal outcomes were more severely affected by snoring.
Conclusions: Snoring is more prevalent among women with pregnancy-induced hypertension and is associated with more severe hypertension and adverse outcomes.
