Abstract: | This study investigated the effects of prenatal cocaine exposure on infant sensorimotor development. One hundred and sixty-seven12-month-olds (74 cocaine-exposed and 93 unexposed) were assessed using the Bayley Scales of Infant Development (BSID). Ninety-seven had previously been evaluated on the Movement Assessment of Infants and the Test of Sensory Functions in Infants at age 4 months. On the BSID, the cocaine-exposed infants performed less well on the Mental portion and were more frequently rated as behaviorally suspect. Cocaine-exposed infants also performed less well at four months on the motor and sensory measures. Early motor performance predicted 12 month BSID mental, motor and behavioral outcomes. Cocaine exposure had an effect independent from confounders on general cognitive and specific motor and behavioral outcomes. |
