Abstract
Background
Rectal gonorrhea and Chlamydia are common and predict HIV acquisition among men who have sex with men (MSM); however, screening for rectal sexually transmitted infections (STIs) is not routine.
Methods
In 2017, we recruited sexually-active MSM in the Portland, Oregon metropolitan area through venue-based sampling. Our outcome of interest was self-reported rectal STI screening in the prior 12 months. Stratified by HIV status, we assessed the prevalence and demographic, healthcare, clinical, and behavioral predictors of screening.
Results
Of 448 participants, 168 (37.5%) reported rectal STI screening. One hundred twenty-seven (35.8%) of 355 HIV-negative men, 41 (58.6%) of 70 HIV-positive men, and none of 23 men who did not know their HIV status reported screening. Among HIV-negative men, having a healthcare provider who offered HIV testing (adjusted prevalence ratio [aPR]=2.09; 95% confidence interval [CI]: 1.43, 3.04), a syphilis diagnosis (aPR=1.32; 95% CI: 1.03, 1.69), use of pre-exposure prophylaxis (aPR=1.57; 95% CI 1.21, 2.04), and condomless anal sex with casual partners in the prior 12 months (aPR=1.74; 95% CI: 1.36, 2.22) independently predicted screening for rectal STI in multivariable analysis. HIV-positive men who reported having a provider who always or often initiates conversations about sex were significantly more likely to report screening compared with men who did not have such a provider (aPR=1.48; 95% CI: 1.06, 2.06).
Conclusion
Rectal STI screening is not universal in a venue-based sample of sexually-active MSM. Implementing innovative, acceptable, and accessible screening practices and improving provider comfort with talking about sex are paramount to increasing rectal STI screening.
