HIV Testing Frequency Among Men Who Have Sex With Men Attending Sexually Transmitted Disease Clinics: Implications for HIV Prevention and Surveillance

OBJECTIVES:To describe trends in the occurrence and frequency of HIV testing among men who have sex with men (MSM) receiving care in 4 US sexually transmitted disease (STD) clinics and to define factors associated with HIV testing frequency and positivity. STUDY DESIGN:Routine clinical encounters during 57,131 visits by MSM to STD clinics in 4 cities (Seattle-King County, San Francisco, Denver, and District of columbia), 2002-2006, were examined. RESULTS:From 2002 to 2006, a city-specific median of 69.1% of presumptive HIV-uninfected MSM were tested for HIV, of which, a median of 86.7% had previously tested (4.5% unknown) and a median of 3.9% were newly diagnosed with HIV. Between 2002 and 2006, the median percentage of tested MSM who reported no previous HIV testing decreased from 9.4% to 5.4% (P = 0.01) and the city-specific median intertest interval decreased from 302 to 243 days (P = 0.03). Among MSM with newly diagnosed HIV, the median intertest interval decreased from 531 days in 2002 to 287 days in 2006 (P = 0.001). Predictors of newly diagnosed HIV infection included the followingyounger age, longer intertest interval, black or Hispanic race/ethnicity, clinic in San Francisco, and concurrent diagnosis with a bacterial STD. CONCLUSIONS:In MSM seen at 4 STD clinics, the percentage of never previously HIV tested is decreasing and MSM are testing more frequently.
