Insights
Culturally tailored interventions like Rise significantly improve antiretroviral therapy adherence for Black Americans with HIV. This community-based program also reduced HIV stigma and medical mistrust.
Area of Science:
- Public Health
- Health Disparities Research
- Behavioral Science
Background:
- Structural inequities contribute to HIV disparities, impacting adherence and viral suppression among Black Americans.
- Low antiretroviral therapy (ART) adherence and viral suppression rates persist in this population.
- Culturally congruent interventions are needed to address these health inequities.
Purpose of the Study:
- To evaluate the effectiveness of the Rise intervention, a community-based, culturally congruent program, on ART adherence and viral suppression among Black adults living with HIV.
- To assess the intervention's impact on HIV stigma, medical mistrust, and HIV-serostatus disclosure.
- To determine the cost-effectiveness of the Rise intervention.
Main Methods:
- A randomized controlled trial was conducted with 166 Black adults living with HIV in Los Angeles County.
- The intervention group received culturally tailored adherence counseling and social determinants of health referrals.
- Outcomes included electronically monitored adherence, HIV viral load, and survey data collected at baseline, 7, and 13 months.
Main Results:
- The Rise intervention significantly increased adherence likelihood (two-fold) compared to the control group.
- Participants in the Rise group showed significantly lower HIV stigmatizing beliefs and reduced medical mistrust.
- No significant effects were observed on HIV viral suppression, internalized stigma, or disclosure.
Conclusions:
- Culturally tailored interventions, such as Rise, are effective in improving ART adherence for Black Americans living with HIV.
- The Rise intervention demonstrates potential for reducing HIV stigma and medical mistrust within this population.
- Rise is a cost-effective intervention for improving adherence, with an estimated cost of $335 per 10% adherence increase.
Abstract:
Structural inequities have led to HIV disparities, including relatively low antiretroviral therapy adherence and viral suppression rates among Black Americans living with HIV. We conducted a randomized controlled trial of Rise, a community-based culturally congruent adherence intervention, from January 2018 to December 2021 with 166 (85 intervention, 81 control) Black adults living with HIV in Los Angeles County, California [M (SD) = 49.0 (12.2) years-old; 76% male]. The intervention included one-on-one counseling sessions using basic Motivational Interviewing style to problem solve about adherence, as well as referrals to address unmet needs for social determinants of health (e.g., housing services, food assistance). Assessments included electronically monitored adherence; HIV viral load; and baseline, 7-month follow-up, and 13-month follow-up surveys of sociodemographic characteristics, HIV stigma, medical mistrust, and HIV-serostatus disclosure. Repeated-measures intention-to-treat regressions indicated that Rise led to significantly (two-fold) higher adherence likelihood, lower HIV stigmatizing beliefs, and reduced HIV-related medical mistrust. Effects on HIV viral suppression, internalized stigma, and disclosure were non-significant. Moreover, Rise was cost-effective based on established standards: The estimated cost per person to reach optimal adherence was $335 per 10% increase in adherence. Interventions like Rise, that are culturally tailored to the needs of Black populations, may be optimal for Black Americans living with HIV (ClinicalTrials.gov #NCT03331978).
