Burkina Faso-Quantitatively Examine Social and Structural Factors associated with HIV-related Risk Behaviors and Prevalence among Most at Risk Populations

This study in Burkina Faso will focus on size estimations of the SW and MSM populations and implement an integrated HIV serological and behavioral Surveillance. The project is supported through the Research to Prevention (R2P) program which is a 5-year HIV prevention project funded by USAID and led by the Johns Hopkins Center for Global Health and implemented by faculty throughout the University. It is managed by the Center for Communication Programs (CCP) in the Department of Health, Behavior and Society at the Johns Hopkins School of Public Health. This study is conducted collaboratively with the Center for Public Health and Human Rights, in the Department of Epidemiology at the Johns Hopkins Bloomberg School of Public Health. Despite low HIV prevalence among the general population, relative to other regions of sub-Saharan Africa, West and Central Africa contribute a significant proportion of new HIV infections to the global burden due to their large population. While national HIV prevalence ranges from less than one percent to five percent in the region, prevalence among most at risk populations (MARPs), including sex workers (SW) and men who have sex with men (MSM) is significantly higher. This work will focus on female sex workers though prevalence of male sex work will be characterized as a component of the studies focusing on MSM. For instance, HIV prevalence among SW is 30 times the general population prevalence in Niger and Senegal; HIV prevalence among MSM ranges from 13% to 37%. Public health workers need methods to estimate population sizes of hidden high risk groups, in order to lobby for appropriate interventions that are large enough to meet the needs of the population, and efficiently allocate resources. UNAIDS suggests triangulating the results of different methods – including multiplier methods such as the unique object identifier and service statistics - to estimate population size. However, few data are available on the absolute size of these most at-risk populations. Data that do exist, especially in submissions to the Global Fund to fight AIDS, Tuberculosis, and Malaria (GFATM), are not collected through rigorous study and lack technical quality. As highlighted in its HIV Regional Strategy, USAID West Africa is best positioned to provide support for evidence-based data collection and use of these data, a pillar of its Regional HIV Strategy. This study will assist countries to strategize, prioritize and define how much investment should be planned for MARPs groups based on the population size and level of HIV risk behavior. Study Objectives Population Size Estimations of men who have sex with men (MSM) and female sex workers (FSW) Assess the burden of sexually transmitted infections among MSM and FSW including unbiased or population-based HIV and syphilis prevalence assessments Quantitatively and qualitatively assess risk status for sexually transmitted infections among MSM and FSW including individual and structural risk factors
