Self-reported short sleep duration and frequent snoring in pregnancy: impact on glucose metabolism.

Objective We sought to evaluate the impact of short sleep duration (SSD) and frequent snoring (FS) on glucose metabolism during pregnancy. Study Design We conducted a prospective cohort study of healthy nulliparas who participated in a sleep survey study. SSD was defined as Results A total of 189 women participated; 48% reported an SSD and 18.5% reported FS. SSD and FS were associated with higher oral glucose tolerance values: SSD (116 ± 31 vs 105 ± 23; P = .008) and FS (118 ± 34 vs 108 ± 25; P = .04). Both SSD (10.2% vs 1.1%; P = .008) and FS (14.3% vs 3.3%; P = .009) were associated with a higher incidence of GDM. Even after controlling for potential confounders, SSD and FS remained associated with GDM. Conclusion SSD and FS are associated with glucose intolerance in pregnancy.
