| Abstract: | Childhood maltreatment is associated with a range of adverse mental and physical health outcomes, including increased rates of sexually transmitted infections (STIs) later in life. However, the impact on risky sexual behaviors and pregnancy outcomes has not been adequately studied. This is particularly true for physical abuse, emotional abuse, and neglect. We examined associations between prospectively substantiated childhood maltreatment and reports of risky sexual behaviors by men and women, as well as selected pregnancy outcomes in women. We followed up 3,081 (45.7% female) participants from the Mater-University of Queensland Study of Pregnancy, a prospective Australian birth cohort study. Using logistic regression, we examined the association between substantiated childhood maltreatment from birth to 14 years, and self-reported risky sexual behaviors and youth pregnancy outcomes at the 21-year follow-up. In adjusted analyses, children who had experienced multiple childhood maltreatment exhibited more risky sexual behaviors than their nonmaltreated counterparts. In specific models, those exposed to each form of childhood maltreatment, independent of co-occurring forms of childhood maltreatment, had an increased likelihood of risky sexual behaviors, particularly an early sexual debut and, for women, youth pregnancy. Neglect was also associated with multiple sexual partners, and emotional abuse with higher rates of miscarriage. There was no difference between men and women in how different forms of childhood maltreatment predicted risky sexual behaviors in young adulthood. All forms of substantiated childhood maltreatment, including multiple substantiations, were associated with risky sexual behavior in both sexes as well as higher rates of youth pregnancy in women. Moreover, emotional abuse persistently predicted miscarriages in young adult women. Understanding the association between childhood maltreatment and risky sexual behaviors and youth pregnancy outcomes may help suggest preventive strategies. |
