title: Chronicity and severity of maternal postpartum depression and infant sleep disorders: a population-based cohort study in southern Brazil.
abstract: A cohort study was conducted with 397 women randomly selected from the Brazilian National System of Public Health, to describe the prevalence rates of infant sleep problems at 12-month of life, and its association with chronicity and severity of maternal depressive symptoms. Mothers were assessed, first, from the 9th to the 12th week postpartum and then at 12 months after delivery, with EPDS and a self-rating questionnaire regarding babies' sleep behavior. After controlling for possible confounders, babies whose mothers had severe chronic depressive symptoms were at higher risk for sleep disorder at 12 months of birth.
