|Objective: Assess the relative eff ects of a variety of illicit and licit drugs on risk for adverse birth outcomes. Methods: We used data from two large prospective investigations and recursive partitioning class analysis to identify relevant subgroups with diff ering risk levels. Available data included information on substance use as well as established risk factors for adverse birth outcomes. Results: Compared to non-users aged 28-33, cocaine users were 5 times more likely than non-users to deliver preterm (95% CI: 2.32-13.29; p=0.0001). Th e odds for delivery of a small for gestational age infant for women who smoked more than two cigarettes daily, was 3.74 (95% CI: 2.47-5.65; p<0.0001) as compared to non-smokers. Similarly, less educated, nulliparous women who smoked 2 or fewer cigarettes daily were 4.12 times as likely (95% CI: 2.04-8.34; p<0.0001) to have a small for gestational age infant. Number of hazardous substances used was not a signifi cant factor for either birth outcome. Conclusions: Among our covariates, prenatal cocaine use is the predominant risk factor for preterm birth; while tobacco use was the primary risk factor predicting small for gestational age at delivery. Multi-substance use did not substantially increase risk of adverse birth outcomes over these risk factors.|
