Primary Outcome Behaviors at 60-Day Follow-up.

All variables have missing data.*HIV disclosure and anal sex variables include sex partner data for up to the 3 last sexual encounters; 1,720 did not report disclosure data due to loss to follow-up (1,461) or drop-out during the follow-up survey (142), no sex during follow-up (104), or only multiple-partner encounter data at baseline and thus no one-on-one encounter data (13).†Unprotected anal intercourse (UAI) was defined as ‘any’ unprotected (without a condom) insertive and/or receptive sex (yes/no).‡HIV Testing among HIV-negative and previously untested status men.§Since baseline, 74 men (5%) reported bacterial and/or newly diagnosed viral sexually transmitted infections (STIs), which included chancroid, chlamydia, gonorrhea, herpes, human papillomavirus, lymphogranuloma venereum, nongonococcal urethritis, syphilis, and hepatitis A, B, or C.
