Age- and Race-Related Differences in Advertised Health Behaviors Among Male Sex Workers in San Francisco Who Have Sex With Men.

Given the stigma surrounding sex work and the illegal nature of many aspects of commercial sex activity, empirical research is lacking regarding the health-related behaviors of sex workers, particularly male sex workers who have sex with men (MSM sex workers). To better understand the MSM sex worker community and their potential health needs, we analyzed certain sexual health-related behaviors as advertised online by MSM sex workers in the San Francisco area. Using descriptive and bivariate statistical tests, we examined whether age- and race-related differences existed among these sex workers in the following publicly advertised behaviors: use of pre-exposure prophylaxis and a willingness to engage in illicit drug use or condomless anal intercourse. Although we found no significant differences by race in terms of advertised pre-exposure prophylaxis use or willingness to engage in condomless sex, our results show statistically significant differences by race with respect to willingness to use drugs. This difference could be driven by the younger average age of the non-White sex workers in our sample. These findings help inform our understanding of MSM sex work and its associated risks.
