HealthDay News -- Pregnancy-onset snoring is associated with a significantly increased risk of gestational hypertension and preeclampsia, according to research published online Sept. 10 in the American Journal of Obstetrics & Gynecology.

Louise M. O'Brien, Ph.D., of the Sleep Disorders Center at the University of Michigan School of Medicine in Ann Arbor, and colleagues conducted a prospective cohort study involving 1,719 pregnant women in their third trimester of pregnancy to determine whether pregnancy-onset habitual snoring, defined as snoring three to four nights per week, was associated with the risk of gestational hypertension, preeclampsia and gestational diabetes.

Overall, 34% of participants reported snoring and 25% reported pregnancy-onset snoring. The researchers found that pregnancy-onset snoring, but not chronic snoring, was associated with a significantly increased risk for gestational hypertension (odds ratio=2.36) and preeclampsia (OR=1.59) but not gestational diabetes, after adjustment for confounders.

"This is the first large, prospective study to demonstrate that pregnancy-onset snoring confers significant risk to maternal cardiovascular health," the researchers wrote. "These novel findings strongly implicate a role not only for snoring in general but, more specifically, for pregnancy-onset snoring in both gestational hypertension and preeclampsia."
