Willingness of us men who have sex with men (MSM) to participate in couples HIV voluntary counseling and testing (CVCT)

Background: We evaluated willingness to participate in CVCT and associated factors among MSM in the United States. Methods: 5,980 MSM in the US, recruited through MySpace.com, completed an online survey March-April, 2009. A multivariable logistic regression model was built using being "willing" or "unwilling" to participate in CVCT in the next 12 months as the outcome. Results: Overall, 81.5% of respondents expressed willingness to participate in CVCT in the next year. Factors positively associated with willingness were: being of non-Hispanic Black (adjusted odds ratio [aOR]: 1.5, 95% confidence interval [CI]: 1.2-1.8), Hispanic (aOR: 1.3, CI: 1.1-1.6), or other (aOR: 1.4, CI: 1.1-1.8) race/ethnicity compared to non-Hispanic White; being aged 18-24 (aOR: 2.5, CI: 1.7-3.8), 25-29 (aOR: 2.3, CI: 1.5-3.6), 30-34 (aOR: 1.9, CI: 1.2-3.1), and 35-45 (aOR: 2.3, CI: 1.4-3.7) years, all compared to those over 45 years of age; and having had a main male sex partner in the last 12 months (aOR: 1.9, CI: 1.6-2.2). Factors negatively associated with willingness were: not knowing most recent male sex partner's HIV status (aOR: 0.81, CI: 0.69-0.95) compared to knowing that the partner was HIV-negative; having had 4-7 (aOR: 0.75, CI: 0.61-0.92) or >7 male sex partners in the last 12 months (aOR: 0.62, CI: 0.50-0.78) compared to 1 partner; and never testing for HIV (aOR: 0.38, CI: 0.31-0.46), having been tested over 12 months ago (aOR: 0.63, CI: 0.50-0.79), or not knowing when last HIV tested (aOR: 0.67, CI: 0.51-0.89), all compared to having tested 0-6 months previously. Conclusions: Young MSM, men of color, and those with main sex partners expressed a high level of willingness to participate in couples HIV counseling and testing with a male partner in the next year. Given this willingness, it is likely feasible to scale up and evaluate CVCT interventions for US MSM.
