Objective: To assess features of sleep among pregnant women. Methods: We conducted a prospective cohort study of low-risk pregnant women in a tertiary perinatal centre (CHUS) in Eastern Townships, Quebec. Sleep was assessed during the second trimester (mean gestational age 16.1 ± 3.0 weeks) (T2) and third trimester (mean gestational age 27.5 ± 1.8 weeks) (T3) using a validated self-administered questionnaire, the Pittsburgh Sleep Quality Index (PSQI). Scores in this index range from 0 to 21, representing the cumulative scoring of seven sleep components.
