Preferences for PrEP Selection: A Pilot Study of a Discrete Choice Experiment Among Sexual Minority Men in the U.S.

Despite the disproportionate burden of HIV among sexual minority men (SMM), PrEP is underutilized among this population. This study used a discrete choice experiment (DCE) to examine preferences and concerns related to PrEP uptake among HIV-negative, PrEP-eligible SMM (n = 271). Participants evaluated hypothetical PrEP profiles based on administration method, side effects, provider language, and peer use. On-demand PrEP was preferred over daily and long-acting injectable regimens. Side effects, particularly headaches and nausea, were rated as more influential than other attributes. Participants who knew someone taking PrEP had increased odds of taking PrEP themselves. Language concordance with providers did not significantly affect preferences. These findings underscore the importance of flexible PrEP options and minimizing side effects to increase acceptability. Tailoring healthcare delivery and messaging to these preferences may improve PrEP uptake among SMM.
