Background: 

CDC recommends annual HIV testing for persons at risk for acquiring HIV infection, including sexually active men who have sex with men (MSM).  We examined rates and trends in HIV testing in the prior 12 months among men at risk for HIV infection.

Methods: 

Using data from the 2002 and 2006-08 cycles of the NSFG (a nationally representative survey of Americans aged 15-44 years), we assessed proportions of male respondents who reported having tested for HIV infection in the prior 12 months, stratified by sexual behavior.  High-risk sexual behavior was defined as sex with injection drug users, HIV-infected persons, multiple partners, non-monogamous partners, any male partners, or sex in exchange for drugs or money in the prior 12 months.  Estimates were weighted for unequal selection probabilities and nonresponse using SAS 9.2 and SUDAAN 10 to adjust for the complex NSFG sampling design.

Results: 

Among an estimated 123,346,447 men (based on 11,067 male respondents), 22.6% (95% confidence intervals [CI] 21.1-24.0) reported having engaged in high-risk sexual behavior in the prior 12 months, of which 23.5% (CI 21.2-25.9) reported HIV testing in the prior 12 months.  In contrast, men without any high-risk sexual behavior had lower rates of HIV testing in the prior 12 months (10.8% [CI 9.7-12.0], p<0.01).  From 2002 to 2006-08, the proportion of men with high-risk sexual behavior who tested in the prior 12 months remained stable overall (24.5% [CI 20.9, 28.0] and 22.4% [CI 19.2, 25.7] respectively, p=0.41).  Among an estimated 2,937,823 men with ≥ 1 male sex partner in the prior 12 months (based on 367 respondents), 39.3% tested for HIV infection in the prior 12 months.  From 2002 to 2006-08, the proportion of men with ≥ 1 male sex partner in the prior 12 months who tested within that period remained stable overall (37.2% and 41.9%, respectively, p=0.56).

Conclusion: 

Less than half of men with high-risk sexual behavior, including sexually active MSM, reported HIV testing in the prior 12 months, with little improvement from 2002 to 2006-08.  In the US, MSM are disproportionately impacted by the HIV epidemic, with higher rates of new HIV diagnoses. Programs to increase rates of annual HIV testing for MSM are critically needed to decrease unrecognized infection and transmission of HIV.
