Objectives: To determine any predictors of bacterial sexually transmitted infections (STIs) among men who have sex with men (MSM) in Atlanta GA and to determine if CDC PrEP eligibility correlates to positive STI diagnosis.
Methods: A subgroup of HIV negative non-Hispanic white and black MSM was gathered from the InvolveMENt and The MAN Project studies. Participants completed a computer based questionnaire with questions about demographic, psychosocial, individual level sexual risk behaviors, and dyadic information. Men were also screened for chlamydia, gonorrhea, and syphilis.
Results: 265 participants were selected for analysis. Racial composition was 57.0% black and 43.0% white. 33 (12.5%) participants were diagnosed with at least one STI. Prevalence of chlamydia was 8.7%, gonorrhea 6.0%, and syphilis 1.5%. Multiple infection prevalence was 3.8% with 90% of co-infections chlamydia and gonorrhea, and 10% chlamydia and syphilis. Rectal infections were more common than urethral infections Predictors of a positive STI diagnosis were black race, lower education, and lack of health insurance. CDC PrEP eligibility guidelines were not associated with STI diagnosis.
Conclusion: Atlanta MSM exhibit high prevalence of bacterial STIs with respect to racial and educational divisions. CDC PrEP eligibility guidelines do not fit this population and should be altered to better predict individuals who are engaging in high risk behaviors and acquiring bacterial STIs.
