Abstract
Substance use during pregnancy is associated with poor obstetrical and neonatal outcomes. Although intervention for substance use including alcohol improves pregnancy outcomes, a substantial number of women continue to use drugs or consume alcohol during treatment. To determine whether gestational age at entry into treatment (specifically first trimester enrollment) was associated with lower risk of continued substance use, we analyzed the North Carolina Treatment Outcomes and Program Performance System, an administrative database of drug treatment clinics, between 2000 and 2004. There were 847 pregnant women using substances who met our inclusion criteria. Demographic and other risk factor data were collected. We conducted logistic regression and a Generalized Estimating Equation analysis. Gestational age at enrollment was not associated with continued substance use (odds ratio [OR] = 0.88; 95% confidence interval [CI] = 0.51, 1.51). Women who had child care provided, were less likely to continue substance use (OR = 0.64; 95% CI = 0.48, 0.84), whereas those referred from the criminal justice system were more likely to continue (OR = 1.53; 95% CI = 1.01, 2.30). Although earlier gestational age at enrollment in treatment does not predict greater abstinence at any time point, this data does suggest that the provision of childcare may improve treatment success.
