Men who have sex with men receiving HIV care reported their sexual behaviours and their intentions, classified according to the Transtheoretical Model of Change, to modify the following behaviours: (1) condom use by partner type and activity type; (2) reduction of partner number; and (3) disclosure of HIV serostatus to partners. Most participants were white (68.8%) or black (29.5%) and were more likely to report unprotected sex with HIV-positive than with serodiscordant partners for most activities. Whites reported more partners than black patients (mean 4.1 versus 2; P < 0.0001) and black participants reported fewer HIV-negative (P = 0.0084) and -unknown status partners (P = 0.00095) than whites. Cocaine/crack use was associated with more sexual partners (P = 0.001) and more frequent unprotected sex with HIV-negative or -unknown status partners (P = 0.036). Readiness to change risk behaviour varied by partner status and type of sexual activity. Understanding patients' risks and their readiness to change behaviours may help providers to promote sexual health.
