Tathmini Gender Based Violence Study in Tanzania

Tathmini cluster randomised trial assessed the impact of a gender-based violence (GBV) prevention programme in Tanzania which was delivered through a HIV/AIDS programme platform. The programme was implemented in the Mbeya Region, where high HIV and GBV prevalence was recorded. It aimed to increase the knowledge of GBV, decrease acceptance of GBV as a cultural norm, shift gender norms toward greater equity, strengthen community responses to GBV, and increase availability and access to GBV services.

Twelve health facilities and surrounding communities in the Mbeya Region of Tanzania were randomly assigned to intervention or control arms. Population-level effects were measured through two cross-sectional household surveys of women ages 15–49, at baseline (n = 1,299) and at 28 months following programme scale-out (n = 1,250). Delivery of GBV services was assessed through routine recording in health facility registers.

The study demonstrated the feasibility and impact of integrating GBV and HIV programming to combat both of these major public health problems.

Key Findings

52 percent of women reported experiences of recent IPV at baseline. It decreased by 29 percent from baseline to follow-up in the absence of the intervention (time effect OR = 0.71, 95% CI: 0.57–0.89). The intervention contributed to an additional 15 percent reduction, even though the effect was not statistically significant.

The programme was found to contribute to positive, community-wide changes including less tolerance for certain forms of violence, more gender equitable norms, better knowledge about GBV, and increased community actions to address violence.

The programme also led to increased utilisation of GBV services at health facilities. Nearly three times as many client visits for GBV were recorded at intervention (N = 1,427) compared to control (N = 489) facilities over a 16-month period. These visits were more likely to include provision of an HIV test (55.3% vs. 19.6%, p = .002).
