The impact of an economic empowerment intervention on intimate partner violence among women engaged in sex work in southern Uganda: A cluster randomized control trial.

Women engaged in sex work (WESW) are at heightened risk of experiencing intimate partner violence (IPV) compared to women in the general population. This study examines the impact of an economic empowerment intervention on IPV among WESW in Southern Uganda. We used data from 542 WESW in Southern Uganda recruited from 19 HIV hotspots between June 2019 and March 2020. Eligible participants were 18+ years old, engaged in sex work-defined as vaginal or anal sexual intercourse in exchange for money, alcohol, or other goods, reported at least one episode of unprotected sexual intercourse in the past 30 days with a paying, casual, or regular sexual partner (spouse, main partner). We analyzed data collected at baseline, 6, and 12months of follow up. To examine the impact of the intervention on IPV, separate mixed-effects logistic regression models were run for each type of IPV (physical, emotional, and sexual) as experienced by participants in the last 90 days. Results show that the intervention was efficacious in reducing emotional and physical IPV as evidenced by a statistically significant intervention main effect for emotional IPV, χ2(1) = 5.96, p = 0.015, and a significant intervention-by-time interaction effect for physical IPV, χ2(2) = 13.19, p < 0.001. To qualify the intervention impact on physical IPV, pairwise comparisons showed that participants who received the intervention had significantly lower levels of physical IPV compared to those in the control group at six months (contrasts = -0.12 (95% CI: -0.22, -0.02), p = 0.011). The intervention, time, and intervention-by-time main effects for sexual IPV were not statistically significant. Our findings suggest economic empowerment interventions as viable strategies for reducing emotional IPV among WESW. However, it is also essential to understand the role of interventions in addressing other forms of IPV especially for key populations at high risk of violence, HIV, and STI. The study was registered at ClinicalTrials.gov, ID: NCT03583541.

Costing of a Combination Intervention (Kyaterekera) Addressing Sexual Risk-Taking Behaviors among Vulnerable Women in Southern Uganda.

In Uganda, women engaged in sex work (WESW) are a marginalized population at the intersection of multiple vulnerabilities. The Kyaterekera intervention is targeted at WESW in Rakai and the greater Masaka regions in Uganda and combines a traditional HIV risk-reduction approach with a savings-led economic empowerment intervention and financial literacy training. We estimated the economic costs of the Kyaterekera intervention from a program provider perspective using a prospective activity-based micro-costing method. All program activities and resource uses were measured and valued across the control arm receiving a traditional HIV risk-reduction intervention and the treatment arm receiving a matched individual development savings account and financial literacy training on top of HIV risk reduction. The total per-participant cost by arm was adjusted for inflation and discounted at an annual rate of 3% and presented in 2019 US dollars. The total per-participant costs of the control and intervention arms were estimated at $323 and $1,435, respectively, using the per-protocol sample. When calculated based on the intent-to-treat sample, the per-participant costs were reduced to $183 and $588, respectively. The key cost drivers were the capital invested in individual development accounts and personnel and transportation costs for program operations, linked to WESW's higher mobility and the dispersed pattern of hot spot locations. The findings provide evidence of the economic costs of implementing a targeted intervention for this marginalized population in resource-constrained settings and shed light on the scale of potential investment needed to better achieve the health equity goal of HIV prevention strategies.
