AbstractIntroductionExperiences of violence during youth contravene young people's rights and increase the risk of depression and poor human immunodeficiency virus (HIV) care outcomes among youth living with HIV (YLWH). Intervention targets for mitigating the negative psychosocial effects of violence are needed, particularly in areas like rural South Africa where violence remains pervasive and mental healthcare is limited. This study aims to quantify the associations between physical and sexual violence and depressive symptoms in YLWH in rural South Africa and explore the modification of these associations by key measures of psychosocial well‐being.MethodsWe conducted a cross‐sectional survey among 362 YLWH ages 12 to 24 in rural South Africa to ascertain participants' history of physical and sexual violence, current depressive symptoms (Center for Epidemiological Studies‐Depression Scale) and levels of social support (Medical Outcomes Social Support Scale), resilience (Conner‐Davidson Resilience Scale) and self‐esteem (Rosenberg Self‐Esteem Scale). Log‐binomial regression was used to estimate the association between history of physical or sexual violence and clinically meaningful depressive symptoms (scores 16). Effect measure modification by high versus low resilience, social support and self‐esteem was assessed using likelihood ratio tests (α = 0.20).ResultsA total of 334 individuals with a median age of 21 (interquartile range: 16 to 23) were included in this analysis. Most participants were female (71.3%), single (81.4%) and attending school (53.0%). Ninety‐four participants (28.1%) reported a history of physical or sexual violence and 92 individuals (27.5%) had clinically meaningful depressive symptoms. Meaningful depressive symptoms were significantly higher among participants with a history of physical or sexual violence as compared to those with no history of violence (adjusted prevalence ratio: 2.01; 95% CI: 1.43, 2.83). However, this association was significantly modified by social support (p = 0.04) and self‐esteem (p = 0.02).ConclusionsIn this setting, the prevalence of meaningful depressive symptoms was significantly higher among YLWH with a history of physical or sexual violence as compared to those without a history of violence. However, higher levels of self‐esteem or social support appeared to mitigate this association. Programmes to improve self‐esteem and social support for youth have the potential to minimize depressive symptoms in YLWH who have experienced physical or sexual violence.

AbstractIntroductionTo maximize impact and minimize costs, antiretroviral pre‐exposure prophylaxis (PrEP) interventions should be offered to those at highest risk for HIV infection. The risk score derived from the VOICE trial is one tool currently being utilized to determine eligibility in adolescent PrEP trials in sub‐Saharan Africa. This study is aimed at evaluating the utility of the risk score in predicting HIV incidence among a cohort of adolescent girls in rural South Africa.MethodsWe utilized data from HIV Prevention Trials Network (HPTN) 068, a phase III randomized controlled trial conducted in rural Mpumalanga province, South Africa. School‐attending young women aged 13 to 20 years were enrolled into the trial from 2011 to 2012 and followed for up to three years. A risk score based on individual‐level risk factors measured at enrolment was calculated for HPTN 068 participants who completed a one‐year follow‐up visit and were HIV seronegative at enrolment. Possible scores ranged from 0 to 10. A proportional hazards model was then used to determine if risk score at enrolment was predictive of incident HIV infection at follow‐up and an area under the curve analysis was used to examine the predictive ability of the score.Results and DiscussionThe risk score had limited variability in the HPTN 068 sample. Scores ≥5 identified 85% of incident infections from 94% of the sample, compared to the VOICE sample in which scores ≥5 identified 91% of incident infections from only 64% of participants. The risk score did not predict HIV incidence after one year of follow‐up (hazard ratio = 1.029; 95% confidence interval (CI): 0.704, 1.503, p = .884) and showed poor predictive ability (area under the curve = 0.55; 95% CI: 0.44, 0.65). Certain individual risk factors that comprise the risk score may be context specific or not relevant for adolescent populations. Additional factors should be considered when assessing risk for the purposes of determining PrEP eligibility.ConclusionsThe VOICE risk score demonstrated low utility to predict HIV incidence in the HPTN 068 sample. Findings highlight the need for an age and developmentally appropriate tool for assessing risk for HIV infection among adolescents. Use of the VOICE risk score for determining PrEP eligibility in younger populations should be carefully considered.
