Traumatic stress and the mediating role of alcohol use on HIV-related sexual risk behavior: results from a longitudinal cohort of South African women who attend alcohol-serving venues

Alcohol Use as a Predictor of Risky Sexual Behaviour among Young Adults in the Western Cape Province of South Africa

The aim of this study was to investigate the relation between alcohol consumption and risky sexual behaviour (RSB). This study further aimed to examine whether alcohol use, gender, and employment status predicted RSB among young adults in the Cape Flats. A better understanding of these predictors could potentially lead to a more thorough comprehension of the relation between alcohol consumption and RSB among young adults within the South African context. The study employed a cross-sectional correlational survey design, with a sample of 1001 participants aged 18 to 25 (51% women), using the street-intercept method. Participants were selected using purposive sampling, with age and geographical location employed as inclusion criteria. We used the Self-Report Risky Sexual Behaviours Scale (SRSBS) and the Alcohol Use Disorder Identification Test (AUDIT), which were cognitively tested and modified, in English and Afrikaans. The data were analysed via multivariate multiple regression analysis in Stata. The key findings indicate that alcohol consumption is an important predictor of RSB. Alcohol consumption accounted for 23.22% of the variation in RSB. We also found that alcohol consumption and gender were significant (p < 0.1) predictors of RSB, but not employment status (p > 0.01). Being a woman decreased RSB. The model indicates that alcohol use and gender explain 18.41% of the variance in RSB. This study provides support for the growing body of research evidence that has established a significant link between alcohol consumption and RSB, highlighting the need for longitudinal research to determine patterns of risky drinking in the general population.

Differences in Access to HIV Services and Risky Sexual Behaviors Among Malawian Women at Social Venues Who Do and Do Not Engage in Sex Work

In the high HIV-burden country of Malawi, female sex workers (FSW) are one of the populations most profoundly affected by HIV. The Malawi Priorities for Local AIDS Control Efforts (PLACE) surveyed 1,004 self-identified FSW, 213 other FSW (OFSW), and 130 other high risk women (OHRW) at social venues. Analyses compared the three groups using survey-weighted log binomial regression models. Each group had a distinct pattern of usage and access to services: OFSW and FSW had greater access to condoms, while using a condom ever was greatest among FSW. Nearly all women knew where to get tested for HIV but very few used FSW drop-in centers. HIV prevalence was high in all three groups (35% FSW, 20% OFSW, 20% OHRW). Given these results, HIV services should be targeted to all women at social venues in Malawi, regardless of sex worker status to improve health outcomes and limit onward transmission of HIV.

Examining the Influence of Trauma Exposure on HIV Sexual Risk Between Men and Women in Post-Conflict Liberia

The adverse impact of exposure to war-related traumatic events on mental health is well documented. Few studies, however, have focused on the impact of exposure to war-related traumatic events on HIV sexual risk behavior in post-conflict countries such as Liberia. We investigated whether exposure to war-related traumatic events was linked to HIV sexual risk behavior, and identified potential mediators of this relationship, including stressful life events, problematic alcohol use, and intimate partner violence (IPV) among women and men in Liberia. Data were collected from a sample of 395 participants in Monrovia, Liberia. Results from the serial multiple mediator model did not support direct or indirect effects between war-related traumatic events and HIV sexual risk behavior among women. For men, we found both direct and indirect effects between war-related traumatic events and HIV sexual risk behavior. Findings from this research highlight the need for trauma-informed HIV prevention strategies in Liberia.

Gender Disparities in Traumatic Life Experiences and Antiretroviral Therapy Adherence Among People Living with HIV in South Carolina

People living with HIV are at increased risk for experiencing trauma, which may be linked to reduced adherence to antiretroviral therapy (ART), making it more difficult to achieve and maintain viral suppression. The current study sought to assess whether traumatic life experiences were associated with lower ART adherence among a diverse sample of people living with HIV in South Carolina. A cross-sectional survey was completed by 402 individuals receiving HIV care from a large immunology center. Principal component analysis revealed three primary categories of trauma experience (extreme violence/death-related trauma, physical and sexual assault, and accidental/disaster-related trauma). Multivariable logistic regression models using complete case analysis and multiple imputation were used to determine the associations between experiencing each trauma category and ART adherence. Complete case analysis showed that overall, participants who reported exposure to any trauma were 58% less likely to be adherent to their ART (adjusted OR 0.42; 95% CI 0.21-0.86) compared to respondents who did not experience trauma. Participants exposed to extreme violence/death-related trauma were 63% less likely to be adherent to their ART (adjusted OR 0.37; 95% CI 0.15-0.95) compared to respondents who did not experience trauma. Participants exposed to physical and sexual assault were 65% less likely (adjusted OR 0.35; 95% CI 0.16-0.77) and those who reported experiencing accidental/disaster-related trauma were 56% less likely (adjusted OR 0.44; 95% CI 0.21-0.93) to report being ART adherent compared to participants who did not experience trauma. Analyses with multiple imputation yielded similar findings as the complete case analyses. When the data were analyzed separately by gender, the associations between overall trauma, extreme violence/death-related trauma, and physical and sexual assault were statistically significant for men using complete case and multiple imputation analyses. There were no statistically significant associations between trauma and ART adherence among women. Findings highlight the need to adopt trauma-informed approaches and integrate trauma- and gender-specific interventions into HIV clinical care in the Southern United States.

Toward Development of Enhanced Preventive Interventions for HIV Sexual Risk among Alcohol-Using Populations: Confronting the 'Mere Pause from Thinking'

The papers in this issue detail state-of-the science knowledge regarding the role of alcohol use in HIV/AIDS risk, as well as offer suggestions for ways forward for behavioral HIV prevention for at-risk alcohol-using populations. In light of recent evidence suggesting that the anticipated uptake of the newer biomedical HIV prevention approaches, prominently including pre-exposure prophylaxis, has been stalled owing to a host of barriers, it has become ever more clear that behavioral prevention avenues must continue to receive due consideration as a viable HIV/AIDS prevention approach. The papers collected here make a valuable contribution to "combination prevention" efforts to curb HIV spread.

Sustained High HIV Incidence in Young Women in Southern Africa: Social, Behavioral, and Structural Factors and Emerging Intervention Approaches

Young women in southern Africa experience some of the highest incidence rates of HIV infection in the world. Across southern Africa, HIV prevalence among women increases rapidly between the teenage years and young adulthood. Adult HIV prevalence is 16.8 % in South Africa, 23 % in Botswana, 23 % in Lesotho, and 26.5 % in Swaziland. Existing research has illuminated some of the key social, behavioral, and structural factors associated with young women's disproportionate HIV risk, including gendered social norms that advantage male power in sexual relationships and age disparities in relationships between younger women and older male partners. Important structural factors include the region's history of labor migration and legacy of family disruption, and entrenched social and economic inequalities. New interventions are emerging to address these high levels of HIV risk in the key population of young women, including structural interventions, biomedical prevention such as PrEP, and combined HIV prevention approaches.
