P023 Internet exposure on sexual partners and sexual risk behavior among sexually experienced college males: evidence from a population-based study

Catechol-O-methyltransferease (COMT) metabolizes prefrontal cortex dopamine (DA), a neurotransmitter involved in executive behavior; the Val158Met genotype has been linked to executive dysfunction, which might increase sexual risk behaviors favoring HIV transmission. Main and interaction effects ofCOMTgenotype and executive functioning on sexual risk behavior were examined. 192 sexually active nonmonogamous men completed a sexual behavior questionnaire, executive functioning tests, and were genotyped using blood-derived DNA. Main effects for executive dysfunction but notCOMTon number of sexual partners were observed. ACOMTx executive dysfunction interaction was found for number of sexual partners and insertive anal sex, significant for carriers of the Met/Met and to a lesser extent Val/Met genotypes but not Val/Val carriers. In the context of HIV and methamphetamine dependence, dopaminergic overactivity in prefrontal cortex conferred by the Met/Met genotype appears to result in a liability for executive dysfunction and potentially associated risky sexual behavior.

Abstract Objective To examine the prevalence of and factors associated with sexual behavior and pregnancy involvement among adolescents in foster family homes. Methods A cross-sectional study was conducted among a random sample of children living in foster family homes. Logistic regression with Firth’s correction was used to determine factors associated with sexual risk behavior and pregnancy involvement (i.e. having been pregnant or gotten someone pregnant). Results About half of adolescents (aged 13–18 years) in foster family homes ever had sex, of whom, one third had first sex before the age of 14 and one sixth had two or more sexual partners in the past 3 months. Of adolescents in the study, 9% had ever been pregnant or gotten someone pregnant. Although adolescents in foster family homes had higher rates of sex initiation and pregnancy involvement than those in the general population, the two groups had comparable rates of current sexual risk behavior. Being placed in kin/fictive kin foster homes [odds ratio (OR): 3.04; 95% confidence interval (CI): 1.18–7.80] and number of placement settings (OR: 1.20; 95% CI: 1.02–1.42) were associated with multiple sexual partners, while a history of running away from a foster home (OR: 7.64; 95% CI: 1.87–31.18) was associated with pregnancy involvement. Conclusions Efforts targeting placement stability including prevention of running away may reduce sexual risk behavior and pregnancy involvement among adolescents in foster family homes.
