  • Weighted analysis was conducted using RDSAT software.

  • Unweighted analysis was conducted using STATA software.

  • Due to small N, some categories were collapsed for multivariate data analysis: (1) straight and bisexual MSM was collapsed; (2) single MSM was collapsed with MSM who lived with a male partner; and (3) married MSM was collapsed with MSM who lived with a female partner.

  • MSM, men who have sex with men; UAI, unprotected anal intercourse.
