IntroductionFew studies have focused on the transition to adulthood in adults with prenatal alcohol exposure (PAE). In this study, we examine the occurrence of problem behavior at this transition, including mental health problems, substance use, and difficulties with the legal system. The sample is prospective and provides an opportunity to examine effects of a wide range of prenatal exposure. Adults with PAE were expected to show more problem behavior; the impact of level of exposure was examined as well. MethodThe sample was drawn from a predominantly low-income, African-American population. Mothers of the alcohol-exposed participants (n=123) and those in the non-exposed SES-Control group (CONT) (n=59) were recruited at a prenatal visit when information on alcohol and drug use during pregnancy was collected. A disability contrast group (n=54) was recruited at adolescence. The adults with PAE were assigned to three groups varying in physical and cognitive effects of exposure. This report is based on the adults' responses to interviews or questionnaires on problem behavior and laboratory tests related to substance use. ResultsAdults with PAE showed more problem behavior in all three areas than adults from the CONT group. For mental health problems, the exposed group showing cognitive, but not physical effects, had the highest scores; their scores were similar, however, to those of the disability contrast group on several scales. Results for outcomes on substance use and legal difficulties were less consistent, but, when significant effects occurred, the group that was exposed, but neither physically nor cognitively affected, was more likely to show negative outcomes. Males in this group were most involved in these behaviors. ConclusionEffects of PAE continue into early adulthood and affect mental health problems, substance use, and interactions with the legal system. Adults who are exposed, but less physically affected, seem to be the most involved in problem behavior. More research is necessary to examine environmental effects in conjunction with PAE on these outcomes and to provide a basis for developing potential interventions.
