Maternal mood and sleep in children of women at risk for perinatal depression.

Few studies have examined relationships between perinatal depression and sleep in offspring beyond very early childhood. Eighty-five women classified as high risk for major depressive disorder during pregnancy completed measures of mood and their child's sleep 4-7 years postpartum. Mothers with Beck Depression Inventory-II (BDI-II) scores ≥20 reported more sleep problems in their child, and child sleep disruption was a reasonable predictor of maternal BDI-II.
