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.
