Abstract: Sleep disorders could influence pregnancy outcomes but evidence for longitudinal associations is scarce. We established a prospective cohort of women to determine incident sleep issues and their adverse health outcomes during pregnancy and beyond, and present here the baseline cohort profile. Antenatal women in gestational weeks 8–12 were recruited (n = 535) and followed-up in each trimester and at 5–6 weeks postpartum (no attrition). Sleep symptoms and disorders were measured using STOP-Bang and Berlin questionnaires and Pittsburgh Sleep Quality Index. Incident health outcomes were extracted from clinical records. At the time of recruitment, habitual snoring was present in 13.8% of participants; “excessive sleepiness during the day” (EDS) in 42.8%; short (<7 h) sleep duration in 46.4%; “having trouble sleeping” in 15.3%; and “poor subjective sleep quality” in 8.6%. Habitual snoring was strongly associated with irregular menstrual periods for one year preceding pregnancy ( p = 0.014) and higher BMI ( p < 0.001). Higher age was associated with less “trouble sleeping” (OR 0.9, p = 0.033) and longer sleep duration was associated with better “subjective sleep quality” (OR 0.8, p = 0.005). Sleep issues were highly prevalent at baseline and associated with age, irregular menstruation, and obesity. This cohort will provide a robust platform to investigate incident sleep disorders during pregnancy and their effects on adverse pregnancy outcomes and long-term health of women and their offspring.
