Background:  Bacterial STDs have been increasing among MSM, with disproportionate rates detected among Black MSM (BMSM).

Objectives:  To determine the sociodemographic and behavioral factors associated with increased STD prevalence in BMSM in order to enhance the efficacy of prevention interventions. 

Methods:  HPTN 061 recruited 1,555 BMSM in six U.S. cities in 2010-11. The men underwent socio-behavioral and clinical evaluations to assess STD and HIV risk, and to develop appropriate prevention interventions. The present analysis focuses on factors associated with detection of rectal or urethral gonorrhea (GC), chlamydia (CT), and syphilis at the baseline visit.

Results:  The median age of the men was 39 years (range: 18 to 68); 60% reported annual household income < $20,000; 30% identified as exclusively homosexual or gay, 15% did not identify as male; 37% reported using substances during sex; 43% reported depressive symptoms (using CESD≤16). The prevalence of STDs was: rectal GC: 3.5%, urethral GC: 1.3%, rectal CT: 6.4%, urethral CT: 2.0%, syphilis: 2.8%.  Diagnosis of GC was associated with age <30 years (adjusted odds ratio (AOR)=5.2, p<0.001), HIV-infection (AOR=4.1, p<0.001), having an annual household income of >$50,000 (AOR=3.9, p=0.003), and not self-identifying as male (AOR=2.1, p=0.032).  CT diagnosis was associated with age <30 (AOR=4.0, p<0.001), HIV infection (AOR=2.3, p=0.001), not self-identifying as male (AOR=1.9, p=0.021), not using substances during sex (AOR=2.2, p=0.012), and reporting depression (AOR=1.7, p=0.022). Syphilis diagnosis was associated with age <30 years (AOR=2.4, p=0.016), HIV infection (AOR=4.5, p=0.002), and having an annual income between $10,000 and $49,999 (AOR=2.5, p=0.031).

Conclusions:  Bacterial STD prevalence is high among BMSM. HIV infection and younger age were associated with CT, GC, and syphilis infection. Other factors were associated with only one or two of the pathogens studied, suggesting that there are distinct networks for STD transmission among BMSM.

Implications for Programs, Policy, and Research: Culturally-tailored interventions are needed to decrease the spread of STDs among BMSM.
