Abstract: Although condom use is an effective barrier against HIV transmission, some men who have sex with men (MSM) engage in bareback sex (unprotected anal sex in risky contexts) and increase their risk for HIV (re)infection. Understanding MSM's decision to bareback (vis-à-vis condom use) is essential to develop effective HIV/AIDS prevention programs for this population. An ethnically diverse sample of men who bareback (n = 120) was recruited exclusively on the Internet and stratified to include two thirds who reported both unprotected receptive anal intercourse (URAI) and being HIV uninfected. We used exploratory factor analysis to explore the domains within the Decisional Balance to Bareback (DBB) scale, and test the association between DBB and risky sexual behaviors. HIV-positive MSM (n = 31) reported higher costs/losses associated with condom use than HIV-negative men (n = 89). We found two underlying factors in the DBB scale: a Coping with Social Vulnerabilities subscale (eight items; alpha = .89) and a Pleasure and Emotional Connection subscale (five items; alpha = .92). We found a positive association between DBB (i.e. greater gains associated with bareback sex) and URAI occasions, number of partners, and having one or more sero-discordant partners in the past 3 months. We conclude that because MSM may avoid using condoms in order to cope with psychosocial vulnerabilities and create intimacy with other MSM, this population could benefit from alternatives to condoms such as pre/post exposure prophylaxis and rectal microbicides.

Abstract: The beneficial or deleterious effects of employment on youth and well-being have been highly contested. This study explores whether work influences youths' sexual risk correlates in a sample of African Americans (N = 562; 55% females; M = 14.5 years, SD = 0.6 years) followed longitudinally from adolescence to early adulthood. The study used growth curve modeling to test the association between number of hours worked and condom use, sex partners' age differences, and number of partners over time. Working a greater number of hours was associated with less condom use, with the effect varying by youths' grade point average. Working a greater number of hours was associated with older sex partners among female youth. No association was found between work and number of partners. The findings suggest that working during adolescence and early adulthood increased participants' sexual activity, thus lending some support for the work consequences perspective. The implications for future research and youth development programs are discussed.

Abstract: Partner age is associated with youth's sex risk behaviors and sexually transmitted infections. At present, however, it is not known whether the co-occurrence of other risk behaviors is associated with having older sex partners during adolescence and young adulthood. Using growth curve modeling, this study first describes the shape of the age difference between participants and their sex partners across adolescence and young adulthood in a sample of African American youth. Second, whether this model varied systematically by sex, mother's education, and high school dropout was tested. Third, whether age differences were associated with youth's self-acceptance, alcohol use, and employment trajectories over these two developmental periods was assessed. Finally, whether these associations had non-proportional effects over both periods was tested. This study modeled sex partners' age differences nonlinearly, with females being more likely to date older partners at baseline and over time. High school dropouts also reported older partners at baseline. Self-acceptance and the number of hours worked were associated with sex partners' age differences over time, with the effect decreasing over young adulthood years. Alcohol use frequency was also associated with having older partners over time. This study discusses the findings from a health perspective on youth's sexual development.

Abstract: Participation in the workplace has been proposed as a potential structural-level HIV/STI prevention strategy for youth. Only a few cross-sectional studies have explored the effect of work during adolescence and young adulthood on sexual behavior and their results have been mixed. This study builds on this literature by exploring whether work influences youths' sexual behavior in a cohort of African American youth (N = 562; 45% males; M = 14.5 years, SD = 0.6) followed from adolescence to young adulthood (ages 13-25 years). Using growth curve modeling, we tested whether working was associated with older sex partners. Then, we explored the association between sex partner age differences and sexual behaviors (i.e., number of sex partners, condom use, and frequency of sexual intercourse). Finally, we tested whether the relationship between sex partner age differences and sexual behaviors was confounded by working. Working greater number of hours was not significantly associated with having older sex partners. Sex partner age differences was associated with number of partners, condom use, and higher sex frequency. These associations were larger for females. Working was associated with higher sex frequency, after accounting for age differences. We discuss the implications of these findings for future research and program planning, particularly in the context of youth development programs.
