SUBSTANCE USE AND PRENATAL-CARE DURING PREGNANCY AMONG YOUNG-WOMEN

Data on a cohort of young mothers from the National Longitudinal Survey of Youth were examined for use of alcohol, cigarettes and marijuana during pregnancies leading to first births. A substantial proportion of women (45 percent) were found to have used at least one of these substances. White women were more likely to use a substance during pregnancy than were Hispanic or black women; women with the prospective father present in the household were less likely than other women to use a substance. Compared with well-educated and older women, less-educated and younger women were more likely to smoke cigarettes or marijuana during pregnancy, but were less likely to drink alcohol. Only about 13 percent of women used more than one substance. Nineteen percent of the women received no prenatal care in the first trimester of pregnancy. Less-educated and younger women were least likely to receive early prenatal care. Multivariate analysis found no association between neglect of prenatal care and substance use. Rather, the analysis revealed that the two behaviors shared likely antecedents, such as whether the prospective father was in the home prior to the pregnancy.
