Culturally tailored intervention results in fewer STIs and less condomless sex among Black women in criminal justice system

By | May 16, 2021

A randomised clinical trial found that Black justice-involved women who took part in an intervention to prevent STIs and HIV were 54% less likely to be diagnosed with an STI and reported 38% fewer acts of condomless anal and vaginal sex compared to the control group over one year of follow-up.

The intervention featured themes of historical trauma and resiliency and was partly delivered online by an African-American facilitator. Fictional African-American characters narrated the intervention and modelled HIV risk reduction strategies and sexual negotiation skills, among other things.

In 2018, Black women in the United Sates had 23 times the rate of new HIV infections than non-Hispanic White women. The structural racism that leads to these disparities also leads to Black women being overrepresented in the criminal justice system. Community supervision programmes are the largest segment of the justice system and include probation, parole, and community-based alternatives to incarceration programmes.

Glossary

control group

A group of participants in a trial who receive standard treatment, or no treatment at all, rather than the experimental treatment which is being tested. Also known as a control arm.

condomless

Having sex without condoms, which used to be called ‘unprotected’ or ‘unsafe’ sex. However, it is now recognised that PrEP and U=U are effective HIV prevention tools, without condoms being required. Nonethless, PrEP and U=U do not protect against other STIs. 

community setting

In the language of healthcare, something that happens in a “community setting” or in “the community” occurs outside of a hospital.

odds ratio (OR)

Comparing one group with another, expresses differences in the odds of something happening. An odds ratio above 1 means something is more likely to happen in the group of interest; an odds ratio below 1 means it is less likely to happen. Similar to ‘relative risk’. 

In 2016, one in every 23 Black adults living in the US were ordered by a court to participate in community supervision programmes, a rate 3.5 times higher than non-Hispanic White adults. Studies have found very high rates of HIV (up to 17%) and STIs (up to 25%) among samples of mostly Black women in these programmes. An estimated 45% of women in these programmes have a substance use disorder, which is a risk factor for HIV and STI acquisition.

Despite the great need for an intervention to address these STI and HIV risks among Black women in the criminal justice system who use drugs, no such intervention existed. Led by Dr Louisa Gilbert of Columbia University, researchers addressed this gap by developing a culturally tailored intervention using community-based participatory research methods.

Empowering African-American Women on the Road to Health (E-WORTH), is a culturally tailored adaption of a WORTH, a Centers for Disease Control and Prevention best practice HIV/STI intervention for women who use drugs. E-WORTH, designed to be delivered in low-resource community supervision programmes, is woven with Afrocentric themes of historical trauma and resiliency stemming from slavery, Jim Crow and mass incarceration. It covers the challenges faced by Black women in the criminal justice system, such as stigma, racism, and discrimination.

E-WORTH has a one-hour individual online HIV testing and information component. This is followed by four weekly 90-minute group sessions, which also included individual interactive exercises and logs. The intervention covered HIV/STI risks, condom use skills, sexual negotiation skills, intimate partner violence screening and referrals, and safety planning.

The multimedia content in E-WORTH featured fictional characters with different life stories of Black women impacted by HIV, the criminal justice system, and drug use. These characters provided motivational messages, modelled how to support other group members and demonstrated skills such as safer sex negotiation.

Gilbert and colleagues designed a randomised controlled trial, run from 2015 to 2019, that compared E-WORTH to a single 30-minute HIV testing intervention that has proven to be effective and cost-effective in substance use disorder treatment programmes. Both interventions were delivered by African-American facilitators. Free condoms were available to all study participants.

Participants were recruited at community supervision programmes in New York City and through word-of-mouth. Eligible participants were women who identified as African American or Black, who were serving a community supervision sentence in the past 90 days, who reported condomless anal or vaginal sex in the past 90 days, and reported binge drinking, substance use, or substance use disorder treatment in the past 90 days. They also had to report other STI/HIV risks in the previous year, and/or be living with HIV.

A total of 352 women participated in the study, with 172 assigned to E-WORTH and 180 assigned to the control. The average age of participants was 32. All participants identified as Black/African American, and 23% also identified as Latinx. Over half (56%) had completed high school or a general equivalency diploma (GED). Seventeen per cent of participants were married. Sixty-six per cent identified as heterosexual, and 31% identified as bisexual. Almost two-thirds (63%) reported food insecurity, and 20% had been homeless in the past 90 days.

Fifty-nine per cent of participants reported drug use, and 43% reported binge drinking (four or more drinks on one occasion) in the past 30 days. Despite this, only 23% had been in substance use disorder treatment in the past 30 days.

At baseline, the only significant difference between groups was STI rates. Thirty-six per cent of E-WORTH participants tested positive for an STI at baseline, compared to 26% of control participants. Six women in the control group and nine women in the E-WORTH group were living with HIV.

“The structural racism that leads to health disparities also leads to Black women being overrepresented in the criminal justice system.”

Of the 172 E-WORTH participants, 82 completed all sessions and 146 completed the 12 month follow-up. Of the 180 control group participants, 155 completed the 12 month follow-up.

At follow up, E-WORTH participants had 54% lower odds for any STI (odds ratio 0.46, 95% CI, 0.25-0.88, P = .01) compared to the control group. Results were similar after excluding 20 participants who had an STI at baseline that didn’t provide proof of treatment (odds ratio 0.48, 95% CI, 0.23-0.90, P = .02).

During the 12 months of follow-up, E-WORTH participants reported 38% fewer acts of condomless vaginal or anal sex in the past 90 days (incident rate ratio 0.62, 95% CI, 0.39-0.97, P = .04), and 42% fewer acts of condomless sex with their main partner (incident rate ratio 0.58, 95% CI, 0.36-0.92, P = .02) compared to the control group. Other measures of sexual behaviour also suggested an effect of the intervention.

The researchers said that the high rates of baseline STIs and high number of women reporting multiple sex partners (48%), along with structural factors such as homelessness, incarceration, and food insecurity, meant that this cohort was at an increased risk for HIV infection, even though only one new case of HIV was noted at 12 months of follow-up. Of note, E-WORTH did not cover pre-exposure prophylaxis and the new diagnosis of HIV at follow-up was in an E-WORTH participant.

The results of this study show that the culturally tailored E-WORTH intervention was acceptable and effective, with both statistically and clinically significant results. This speaks to the promise of E-WORTH as an STI/HIV prevention intervention among Black women in the criminal justice system, as well as the value in culturally tailoring other effective interventions to better serve the needs of people and communities most impacted by HIV.
