Strategies for promoting HIV testing uptake: willingness to receive couple-based and collective HIV testing among a cross-sectional online sample of men who have sex with men in China.

OBJECTIVES: Low rates of HIV testing drive the rapidly growing HIV epidemic among men who have sex with men (MSM) in China. We examined the potential usefulness of couple-based and collective HIV testing strategies among Chinese MSM. METHODS: A cross-sectional online survey was conducted among 1113 MSM in 2013. Multivariable logistic regression analyses were conducted to identify factors associated with willingness to receive couple-based and collective testing. RESULTS: Acceptability of couple-based testing was very high among participants (86.1%), with a moderate level of interest in collective testing (43.2%). Being 'out' to others about one's sexual identity (adjusted OR (AOR)=1.48, 95% CI 1.01 to 2.17) and having ever had an HIV test (AOR=3.05, 95% CI 2.10 to 4.33) were associated with willingness to receive couple-based testing. Having multiple male anal sex partners in the past 3 months was associated with willingness to participate in collective testing (AOR=1.43, 95% CI 1.03 to 1.99). DISCUSSION: Couple-based and collective HIV testing could help better control the HIV epidemic among Chinese MSM if implemented and promoted in a culturally competent manner.
