Preexposure Prophylaxis in Latin America and the Caribbean-The Barbados Experience.

This study explored oral pre-exposure prophylaxis (PrEP) awareness, and sexual behavior of gay, bisexual, and other men who have sex with men (gbMSM) in Barbados. Factors associated with PrEP use were examined using Pearson chi-square and logistic regression. Of the 171 male participants who completed the survey, 22% were under 25 years old, 70% identified as gay/homosexual, and 59% were single. PrEP awareness was 77%, and of these 29% were current PrEP users. Users were more likely to have stable living arrangements (p < .05) and to identify as gay/homosexual (p=.03). Uptake by current PrEP users was attributed to non-judgmental and confidential PrEP services. Barriers identified by former PrEP users included cost and risks of STIs. Since the PrEP program is free, as is general health care for STIs, this suggests that there may be a knowledge gap. Further studies are needed to explore perceived barriers to the program.
