ABSTRACT
PrEP adoption among African-American men-who-have-sex-with-men (AAMSM) remains low. We applied Diffusion-of-Innovations (DOI) theory to understand PrEP adoption processes among young HIV-negative/status unknown AAMSM (AAYMSM; N = 181; 17-24 years). Quantitative and qualitative analyses were used to examine predictors of PrEP diffusion stages. Most AAYMSM were in the persuasion stage (PrEP-aware, hadn't adopted; 72.4%). Our results suggest that model antecedents are DOI stage-specific. PrEP awareness (knowledge stage) was associated with lower levels of social stigma (p < .03) and greater health literacy (p < .05), while sexual risk (p < .03) and education (p < .03) predicted PrEP adoption (12.2%). PrEP efficacy and side effects were primary innovation characteristics influencing adoption receptivity in the persuasion stage. Interventions to improve PrEP diffusion should be tailored to stage-specific antecedents depending on how a community is stratified across the DOI stages.
RESUMEN: La adopción de Pre-exposición Profilaxis (PrEP) entre hombres afroamericanos que tienen relaciones sexuales con otros hombres (HASH) sige baja. Aplicamos la teoría de la difusión de innovaciones para comprender los procesos de adopción de la PrEP entre los hombres jóvenes afroamericanos que tienen relaciones sexuales con otros hombres (HJASH) VIH negativos/estado desconocido (HJASH; N = 181; 1724 años). Se utilizaron análisis cuantitativos y cualitativos para examinar los predictores de las etapas de difusión de PrEP. La mayoría de los HJASH se encontraban en la etapa de persuasión (conscientes de la PrEP, no la habían adoptado; 72.4%). Nuestros resultados sugieren que los antecedentes del modelo son específicos de la etapas de la difusión de innovaciones. La conciencia de la PrEP (etapa de conocimiento) se asoció con niveles más bajos de estigma social (p <.03) y una mayor alfabetización en salud (p <.05), mientras que el riesgo sexual (p <.03) y la educación (p < .03) predijeron la adopción de la PrEP (12.2%). La eficacia y los efectos secundarios de la PrEP fueron las principales características de la innovación que influyeron en la receptividad de la adopción en la etapa de persuasión. Las intervenciones para mejorar la difusión de la PrEP deben adaptarse a los antecedentes específicos de la etapa, dependiendo de cómo se estratifique una comunidad en las etapas del la difusión de innovaciones.

BACKGROUND: While donor funding is instrumental in initiation and implementation of malaria control efforts, national government contributions are key to local ownership and sustainability. This study explored in-kind contributions of local government and households towards the cost of indoor residual spraying (IRS) interventions in Tanzania. METHODS: Data were collected through interviews with local government officials and technical teams in the IRS project. Household contribution was based on provision of water for IRS. Government contributions included government-provided warehouse and office space, vehicles, and staff labour. In-kind contributions were aggregated at the district, regional and national level. Calculations were based on proportion of total costs of IRS from 2010 to 2012. RESULTS: The mainland government provided larger amounts of in-kind contribution in absolute value (mean of US$454 200) compared to Zanzibar (US$89 163). On average, in-kind contribution was 5.5% of total costs in Zanzibar and 2.9% in mainland. The proportion of government in-kind contribution was higher in Zanzibar versus the mainland (86% vs 50%) while household contribution was higher in mainland compared to Zanzibar (50% vs 14%). CONCLUSION: Government involvement, particularly through budgetary allocations and increased in-kind contribution, needs to be encouraged for malaria control efforts to be locally owned, managed and sustained.
