Initial Engagement in Oral Sex and Sexual Intercourse Among Adolescent Girls With and Without Childhood Attention-Deficit/Hyperactivity Disorder

Abstract

We investigated initial engagement in oral sex and sexual intercourse, as well as number of sexual partners, among a prospectively followed sample of adolescent girls with and without a thorough childhood diagnosis of attention-deficit/hyperactivity disorder (ADHD). Participants were adolescent girls (ages 12-19) followed longitudinally as part of a study of ADHD in females. A diverse sample of 140 girls with clinician-diagnosed ADHD (47 inattentive, 93 combined) and 88 age- and ethnicity-matched comparison girls were initially recruited and invited to partake in research summer programs. We utilized data on initial engagement in oral sex, sexual intercourse, and number of sexual partners, collected during follow-up interviews conducted 5 and 10 years after baseline participation. Girls with a childhood diagnosis of ADHD engaged in oral sex at a significantly younger age and reported nearly twice as many oral sex partners than their typically developing peers. Post hoc tests revealed that group differences were driven largely by girls with the combined presentation of ADHD (i.e., those with childhood histories of both inattention and hyperactivity/impulsivity). No significant differences emerged with respect to age of initial sexual intercourse or number of male sexual intercourse partners. In sum, adolescent girls with ADHD, particularly those with the combined presentation, were more likely to engage in oral sexual activity at a young age and with a greater number of both male and female partners. Findings highlight the need for longitudinal research that quantifies and distinguishes between various forms of sexual behavior and later reproductive and mental health outcomes.
