Challenges in Recruiting African-Born, US-Based Participants for HIV and Tuberculosis Research

Abstract

Research is critical for developing HIV and tuberculosis (TB) programming for U.S. African-born communities, and depends on successful recruitment of African-born people. From January 2014 to June 2016, we recruited African-born people for HIV and TB research in King County, Washington. We compared the characteristics of study participants and the underlying populations of interest, and assessed recruitment strategies. Target enrollment for the HIV study was 167 participants; 51 participants (31%) were enrolled. Target enrollment for the TB study was 218 participants; 38 (17%) were successfully recruited. Of 249 prior TB patients we attempted to contact by phone, we reached 72 (33%). Multiple recruitment strategies were employed with variable impact. Study participants differed from the underlying populations in terms of gender, country of origin and language. Inequities in research participation and in meaningful opportunities for such participation may exacerbate existing health disparities.
