Maternal Snoring May Predict Adverse Pregnancy Outcomes: A Cohort Study in China

Abstract

ObjectiveTo examine the prevalence of snoring during pregnancy and its effects on key pregnancy outcomes.MethodsPregnant women were consecutively recruited in their first trimester. Habitual snoring was screened by using a questionnaire in the 1st and 3rd trimester, respectively. According to the time of snoring, participants were divided into pregnancy onset snorers, chronic snorers and non-snorers. Logistic regressions were performed to examine the associations between snoring and pregnancy outcomes.ResultsOf 3 079 pregnant women, 16.6% were habitual snorers, with 11.7% were pregnancy onset snorers and 4.9% were chronic snorers. After adjusting for potential confounders, chronic snorers were independently associated with gestational diabetes mellitus (GDM) (RR 1.66, 95%CI 1.09–2.53). Both pregnancy onset and chronic snorers were independently associated with placental adhesion (RR 1.96, 95%CI 1.17–3.27, and RR 2.33, 95%CI 1.22–4.46, respectively). Pregnancy onset snorers were at higher risk of caesarean delivery (RR 1.37, 95%CI 1.09–1.73) and having macrosomia (RR 1.54, 95%CI 1.05–2.27) and large for gestational age (LGA) (RR 1.71, 95%CI 1.31–2.24) infants. In addition, being overweight or obese before pregnancy plays an important role in mediating snoring and adverse pregnancy outcomes.ConclusionsMaternal snoring may increase the risk of adverse pregnancy outcomes, and being overweight or obese before pregnancy with snoring is remarkable for researchers. Further studies are still needed to confirm our results.

Maternal intelligence quotient and motor development in early childhood: The mediating role of mother's education

“…Between May 2013 and September 2014, 3474 pregnant women who visited the antenatal clinics of Maternal and Child Health Care Centre in Ma'anshan, Anhui Province of China were recruited in the first trimester. A detailed description of the inclusion and exclusion criteria is available elsewhere . A total of 3273 singleton live children were enrolled at birth after we excluded ectopic pregnancy ( n = 2), spontaneous abortion ( n = 120), therapeutic abortion ( n = 30), stillbirth ( n = 10) and multiple gestation ( n = 39).…”
