Risk Factors Associated With Repeated HIV Testing Among Internet-Using Men Who Have Sex With Men.

Men who have sex with men (MSM) represent a disproportionately impacted risk group for HIV incidence among at-risk U.S. populations. Few studies have identified risk factors associated with HIV testing frequency both within and outside of traditional health care settings. MSM enrolled in a prospective cohort were mailed at-home specimen collection kits and followed for a year. Incidence density rate ratios (IDRR) of testing were calculated, and generalized estimating equations were used to analyze the association between HIV testing and behavioral factors. The incidence rate of testing was higher among Black MSM than White MSM (IDRR: 1.3, 95% confidence interval CI [1.1, 1.5]) and higher among MSM who reported 3+ condomless anal intercourse partners (CAI) than MSM who reported no CAI (IDRR: 1.6, 95% CI [1.3, 2.0]). Increasing availability of HIV testing outside traditional health care settings, including at-home testing kits, in conjunction with targeted behavioral interventions and biomedical treatment p...
