N2 - Background Given the elevated potential for primary or transmitted drug resistance (TDR) among newly HIV-infected individuals, there is a need for a deeper understanding of the baseline resistance patterns present in young men of color who have sex with men. Methods Genotypic data were collected for participants aged 1324 who were enrolled from seven sites. Univariate and bivariate methods were used to describe the prevalence of TDR and characteristics associated with TDR. Results Of the 296 individuals participating in the substudy, 145 (49%) had baseline genotypes. The majority of the individuals were African American (65%) and gay-identified (70%). There was significant variation in genotype availability by site (p < .001). Major surveillance drug resistance mutations were present in 28 subjects (19.3%); the majority were non-nucleoside reverse transcriptase inhibitor mutations (12.4%). Subjects with TDR were less likely to have used alcohol on 1 or more days in the prior 2 weeks. Location was not associated with acquisition of TDR. Conclusions There was a high rate of TDR in a geographically and racially diverse sample of HIV-infected young men of color who have sex with men. This represents a serious public health concern given the young age of this sample and the potential need for long-term antiretroviral therapy. These findings underscore the critical roles of both early case identification and secondary prevention.
