    Limited research has explored how emotional intimate partner violence (IPV) shapes HIV risk behaviors. Using crosssectional data from the HPTN 068 post-trial visit (N=1942), we assessed the association between emotional IPV and its sub-domains (verbal abuse and threats) with condomless sex, transactional sex, and frequent alcohol use among young women in South Africa. In adjusted multivariable logistic regression models, any emotional IPV and verbal IPV were associated with increased odds of condomless sex (aOR: 1.47; 95% CI: 1.15, 1.87; and aOR: 1.48; 95% CI: 1.15, 1.89), transactional sex (aOR: 2.32; 95% CI: 1.74, 3.08; and aOR: 2.02; 95% CI: 1.51, 2.71) and alcohol use (aOR: 1.88; 95% CI: 1.39, 2.53; and aOR: 1.87; 95% CI: 1.37, 2.55). Threats were associated with transactional sex (aOR: 3.67; 95% CI: 2.62, 5.14). Future research should examine this relationship over-time and HIV prevention programs should consider and address emotional IPV.

    Multilevel measures of education and pathways to incident HSV-2 in adolescent girls and young women in South Africa (HPTN 068)
    (2019-12) Marie C.D. Stoner, PhD; Torsten B. Neilands, PhD; Kathleen Kahn, PhD; James P. Hughes, PhD; F. Xavier Gómez-Olivé, PhD; Rhian Twine, MPH; Stephen Tollman; Oliver Laeyendecker, PhD; Catherine MacPhail, PhD; Jennifer Ahern, PhD; Sheri A. Lippman; Audrey Pettifor, PhD
    Purpose: Schooling is associated with a lower risk of Herpes simplex virus type 2 (HSV-2) in adolescent girls and young women, but there is little understanding of the pathways underlying this relationship. Methods: We used data from adolescent girls and young women in South Africa enrolled in the HIV Prevention Trials Network 068 study. We tested a structural equation model where individual household and community education measures were associated directly and indirectly with incident HSV-2 through HIV knowledge, future aspirations, age-disparate partnerships, sex in the last 12 months, and condomless sex. Results: Community, household, and individual measures of schooling were all associated with incident HSV-2 infection through mediated pathways that increased the likelihood of having sex. Low school attendance (<80% of school days) increased the likelihood of having sex through increased age-disparate partnerships and reduced future aspirations. Fewer community years of education increased the likelihood of having sex through increased age-disparate partnerships. Parental education level was indirectly associated with HSV-2 overall, although we could not identify the individual pathways that were responsible for this association. Conclusions: Community and individual schooling interventions may reduce the risk of HSV-2 infection by influencing the likelihood of having sex, partner age, and future aspirations.
