Abstract

Assessments of the possible consequences of prenatal exposure to cocaine have been limited by lack of control for socio-demographic confounders and lack of follow-up into the school years. We evaluated intelligence at ages 6-9 years in 88 children from a cohort of 280 born between September 1, 1985 and August 31, 1986 and identified at birth as cocaine-exposed, and in a group of unexposed (n = 96) births of comparable gender and birthweight. IQ scores did not differ between children with and without prenatal exposure to cocaine (mean 82.9 vs. 82.4, difference = 0.5 points, 95% CI-3.1, 4.1); results were unchanged with adjustment for child height, head circumference and prior residence in a shelter or on the street, and for caregiver IQ and home environment (mean difference = 2.2 points, 95% CI-1.5, 5.8).
