Level of Prenatal Cocaine Exposure and Scores on the Bayley Scales of Infant Development: Modifying Effects of Caregiver Early Intervention and Birth Weight

摘要

ObjectivesThe objectives of this study were 1) to assess whether there is an independent association between the level of prenatal cocaine exposure and infants’ developmental test scores after control of potential confounding variables; and 2) if such an association exists, to determine which biological and social variables, individually and in interaction with each other, may modify it.
