Perinatal cocaine effects on neonatal stress behavior and performance on the Brazelton Scale

Fifty-two newborns were assessed for the effects of maternal cocaine use on their performance on the Brazelton Neonatal Behavior Assessment Scale and on their stress behaviors during the Brazelton as tapped by the Neonatal Stress Scale. The cocaine-exposed newborns experienced more obstetric complications, had smaller head circumferences, showed more limited habituation abilities on the Brazelton Scale, and exhibited more stress behaviors than control newborns.
