Abstract
OBJECTIVE: The aim of this study was to evaluate the risk of obstructive sleep apnea (OSA) to preterm delivery (PTD), using the Berlin Questionnaire (BQ). METHODS: This was a large, prospective cohort study among pregnant Thai women. The BQ was employed for symptom-based OSA screening during the second trimester, and PTD was recorded in 1345 pregnant women. Multivariate models were applied in controlling for potential confounders. RESULTS: The overall prevalence of the high risk of OSA was 10.1 %, and it was significantly associated with pre-pregnancy body mass index and score on the Perceived Stress Scale. An adjusted odds ratio for PTD in women with a high risk of OSA was 2.00 (95 % confidence intervals (CIs) = 1.20, 3.34). Stratified analyses, after adjusting for confounding factors, indicated that a high risk of OSA was associated with an increased risk of spontaneous preterm delivery (odds ratio (OR) = 2.45, 95 % CI = 1.20, 5.02), but not with preterm premature rupture of membranes (OR = 1.61, 95 % CI = 0.61, 4.26), and medically indicated preterm delivery (OR = 1.83, 95 % CI = 0.72, 4.64). CONCLUSION: Pregnant women with a high risk of OSA are at an increased risk of having PTD, compared with pregnant women with a low risk of OSA.
