title: Changes in sleep patterns and depressive symptoms in first-time mothers: last trimester to 1-year postpartum.
abstract: Thirty-eight 1st-time mothers were recruited from childbirth classes and were assessed at 4 different time periods: the last trimester of pregnancy, 2-4 weeks postpartum, 12-16 weeks postpartum, and 12-15 months postpartum. Measures included a daily sleep-wake diary and a depression scale (Center for Epidemiological Studies Depression Scale, CES-D). Results reveal significant differences in week-day night sleep schedules (rise time, time awake due to disruptions, and nap time) at 2-4 weeks postpartum in comparison to other times of measurement. Total sleep time and bedtime was not significantly different between times of measurement. More depressive symptoms were reported at 2-4 weeks postpartum than at later postpartum measurements. Mothers who developed clinically elevated depressive symptoms (CES-D > or = 16) at 2-4 weeks postpartum reported more total sleep time, later rise times, and more time napping at the end of pregnancy in comparison to those mothers that reported fewer depressive symptoms (CES-D < 16) at 2-4 weeks postpartum.
