Brief Summary

To achieve an AIDS-free generation, there is a critical need for programs which go beyond individual-level behavior change to reduce HIV and STI infections among adolescent girls and young women in sub-Saharan Africa. Informed, Motivated, Aware, and Responsible Adolescents and Adults (IMARA) is an evidence-based HIV-prevention intervention for adolescent girls and young women (AGYW) and their female caregivers, which has been adapted for a South African audience. The study will test whether AGYW receiving IMARA will have fewer sexually-transmitted infections (STI) and greater acceptance of HIV testing and counseling (HTC) and pre-exposure prophylaxis (PrEP) at 6-month follow-up compared to AGYW assigned to the health-promotion control intervention.

Detailed Description

Reducing new HIV and STI infections among South African (SA) adolescent girls and young women (AGYW) is global public health priority. SA has the world's largest HIV epidemic, and SA AGYW acquire HIV at twice the rate of and seroconvert on average 5 - 7 years earlier than male peers. As new infections continue to outpace access to and availability of pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART), primary prevention remains the most viable strategy to stem new transmission. SA efforts to prevent HIV transmission in youth focus mostly on individual-level behavior change, but AGYW's persistent HIV disparities are explained by broad social and structural inequities that shape and constrain HIV-risk behaviors. Comprehensive HIV prevention packages that are integrated, synergistic, and tailored to the local epidemiology and cultural context are likely to achieve and sustain maximum reductions in HIV-risk. Female caregivers (FC) are an untapped resource in the HIV prevention toolbox and offer a novel opportunity to strengthen AGYW prevention efforts. AGYW may also be change agents for their FC who want to be positive role models for AGYW, and thus, adopt HIV prevention behaviors, including HTC and PrEP.

This study will evaluate the effectiveness and cost-effectiveness of Informed Motivated Aware and Responsible Adolescents and Adults (IMARA), a multilevel, innovative, family-based HIV prevention program that targets individual, social, and structural drivers of risk. IMARA demonstrated a 43% reduction in incident STI at 12-month follow-up among black 14-18-year-old girls in the US. IMARA has been systematically tailored for the SA context and piloted among AGYW and FC dyads. A two-arm RCT will now be conducted with about 645 AGYW (15-19 years old) and FC dyads. Following randomization, AGYW-FC dyads will participate in a 2-day group workshop (\~12 hours) that includes joint and separate mother and daughter activities. AGYW and FC will complete baseline, 6-, and 12-month assessments, including testing for three STI (chlamydia, gonorrhea, and trichomoniasis). We will offer HTC and PrEP at each assessment and track uptake and linkage to care. AGYW and FC who are HIV-negative and interested in PrEP will receive a one-month supply and referral to a clinic. They will additionally receive treatment and counseling if testing positive for an STI and referral for care at an ART clinic if testing positive for HIV. Data will be collected to determine the costs of IMARA. Analyses will compare AGYW across the intervention and control programs on STI incidence, and PrEP and HTC uptake, in addition to secondary outcomes. We will also evaluate the costs and cost-effectiveness of IMARA with respect to the acquisition of STI and HIV, where possible considering power limitations. Additionally, the intervention's implementation will be explored. The study answers an urgent need to evaluate the effectiveness and cost-effectiveness of combination HIV prevention packages for AGYW.

Exclusion Criteria
  • AGYW will be excluded from the study if they do not have a FC to participate in the study.
  • AGYW and FC will be excluded from the study if they are: a) unable to understand the consent/assent process and provide written informed consent; b) currently enrolled in another research study addressing HIV/STIs/PrEP.

Primary Outcome Measures
NameTimeMethod
Proportion of adolescent girls and young women (AGYW) with a sexually-transmitted infection (STI) at baseline and midline~6 months (from baseline to midline)

A positive test for at least one of three STIs: chlamydia, gonorrhea, and/or trichomoniasis

Proportion of AGYW who complete HIV testing and counseling (HTC) at baseline and midline~6 months (from baseline to midline)

Completion of HTC

Proportion of AGYW who elect to take pre-exposure prophylaxis (PrEP) at baseline and midline~6 months (from baseline to midline)

Uptake of PrEP

Secondary Outcome Measures
NameTimeMethod
Proportion of AGYW with an STI at baseline and endline~12 months (from baseline to endline)

A positive test for at least one of three STIs: chlamydia, gonorrhea, and/or trichomoniasis

Proportion of AGYW who complete HTC at baseline and endline~12 months (from baseline to endline)

Completion of HTC

Proportion of AGYW who elect to take PrEP at baseline and endline~12 months (from baseline to endline)

Uptake of PrEP

Proportion of AGYW who report adherence to PrEP at baseline, midline, and endline~6 months (from baseline to midline) and ~12 months (from baseline to endline)

Adherence to PrEP (where appropriate) will be measured via self-report using items from the Wilson scale (2017)

Proportion of AGYW who report adherence to antiretroviral therapy (ART) at baseline, midline, and endline~6 months (from baseline to midline) and ~12 months (from baseline to endline)

Adherence to ART (where appropriate) will be measured via self-report using items from the Wilson scale (2017)

Proportion of AGYW who report risky sexual behavior at baseline, midline, and endline~6 months (from baseline to midline) and ~12 months (from baseline to endline)

Sexual behavior (e.g., condom use, substance use during sex, number of partners, concurrent partners) will be measured via self-report using the AIDS Risk Behavior Assessment (ARBA) (Donenberg, 2001).

Proportion of AGYW who test positive for HIV at baseline, midline, and endline~6 months (from baseline to midline) and ~12 months (from baseline to endline)

A positive test for HIV during HTC

Intervention cost-effectivenessThe study duration (~2.5 years)

The cost-effectiveness ratio, defined as the incremental cost of the IMARA intervention per infection prevented by the intervention.
