Prospective study of postpartum depression: 4½-year follow-up of women and children.

The consequences of maternal postpartum depression for mothers and children were investigated in a 4 1/2-year follow-up study, which included 70 of 99 women who had participated in an earlier study of postpartum depression. Information about maternal adjustment and depression during the follow-up period and child adjustment at age 4 1/2 years was obtained. Women who had experienced a postpartum depression were predicted to be at increased risk for subsequent depression and poor adjustment of their child. Postpartum depression was directly related to subsequent depression but not child problems. Later depression was related to child problems at 4 1/2 years. We concluded that postpartum depression may increase risk for later maternal depression and in turn increases risk for child behavior problems. Intervening with women who have experienced a postpartum depression may reduce likelihood of future depressions and child behavior problems.
