Abstract

Background: STI screening, i.e., testing for STIs in the absence of any clinical signs or symptoms, is an important public health intervention to decrease STI transmission. Current CDC guidelines recommend MSM be screened for STIs such as syphilis, gonorrhea, chlamydia at least annually. There is remarkable heterogeneity in STI prevalence among MSM, particularly young, black MSM (YBMSM), according to geography, race, and HIV status. In this study, we determined the prevalence of any STI testing in the past 12 months, and to compare the prevalence of urogenital STI screening to any extragenital STI screening and associated factors in Atlanta.

Methods: Study participants were enrolled in the EleMENt study, a prospective, observational cohort study that enrolled YBMSM in Atlanta, Georgia (GA) from 2015 to 2019. In total, there were 464 participants in our cross-sectional sample. We calculated the prevalence of participants having had a STI testing (other than HIV), a urogenital STI test and an extragenital STI test in the past 12 months and described the association of prevalence with demographic and behavioral characteristics. We used multivariate log-binomial regression models to calculate prevalence ratios (PRs) and corresponding 95% confidence intervals.

Results: Among the 300 participants who tested for STI in the past 12 months, 274 (60.8%), 193 (42.8%), and 259 (57.4%) had a urogenital, extragenital, and serology-based syphilis test, respectively. The prevalence of getting STI testing among participants with less than high school education, were half of that among participants attending up to college, post graduate, professional school (crude prevalence ratio (cPR = 0.5). YBMSM with no healthcare access had half the prevalence of urogenital or extragenital testing compared to YBMSM with some form of healthcare access (cPR = 0.5). MSM having STIs symptoms had 20% higher probability of getting extragenital testing compared to asymptomatic YBMSM (cPR = 1.2).

Conclusion: In this large cohort of YBMSM, about two-thirds reported STI testing in the past 12 months. More efforts are needed to increase prevalence of STI testing among YBMSM, especially among men with lower educational attainment, men without healthcare coverage, and asymptomatic men.
