PURPOSE: Sleep disordered breathing (SDB) remains unexplored in pregnancy despite the increasing prevalence of obesity and the anatomic and physiologic changes of pregnancy predisposing to SDB. The purpose of this study is to identify the frequency of SDB symptoms and their association with various pregnancy outcomes.
METHODS: English-speaking women were asked to fill out a survey regarding their sleep habits and symptoms of sleep disordered breathing (SDB) 48 hours postpartum using the multivariable apnea prediction index.Maternal charts were reviewed for pregnancy outcomes. Two weeks following discharge from the hospital, patients were called by phone for additional information regarding the development of any pregnancy related complications since delivery. Statistical analysis compared proportions using Fisher's exact test and medians using the Kruskal Wallis test.
RESULTS: A total of 116 patients were recruited and 84 patients were available for follow up. Of those, 83% were white, age 30.0 + 6.5 (16-50). Pre gestational BMI was 24.8 (17.8-62.7) and BMI at delivery was 31.5 (23.7-62.5). About 93% of gestations were single. Of 116 patients, 44 (40.7%) snored frequently/always, 20 (17.5%) gasped and 8 (7%) frequently/always had apneic episodes. There was no significant association between SDB symptoms and the development of pregnancy induced hypertension, preeclampsia or diabetes at the time of delivery. There was an association between (1) snoring and gasping and reported poor blood pressure control at the two week follow up (p=0.04 and 0.009, respectively); (2) snoring and pregestational BMI (p=0.03) but not with the BMI at delivery; (3) gasping and pregestational BMI and BMI at delivery (p=0.003 and 0.02, respectively). No association was found between weight gain during pregnancy and SDB symptoms.
CONCLUSION: Symptoms of SDB are common in pregnancy. Snoring and gasping are associated with reported poor blood pressure control in the two weeks following delivery.
CLINICAL IMPLICATIONS: Sleep disordered breathing symptoms are common in pregnancy and should be screened for as they may impact pregnancy outcomes.
