The relationship between sleep problems during pregnancy and postpartum depressive symptoms as well as neonatal condition at delivery have not been well described. This study hypothesized that sleep problems are associated with postpartum depressive symptoms and adverse neonatal outcomes at delivery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study conducted a prospective study for perinatal women (<jats:italic>n<\/jats:italic>\u2009=\u2009683, 30.54\u2009\u00b1\u20095.11\u2009years old) to evaluate sleep problems during pregnancy using the Pittsburgh sleep quality index (PSQI) and Berlin questionnaire, postpartum depressive symptoms using Edinburgh postnatal depression scale (EPDS), and clinical signs of neonatal condition at delivery using the Apgar score.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>PSQI total score during pregnancy were significantly higher in those with postpartum depressive symptoms than those without 1\u2009month after delivery.
