Short-term impact evaluation of a social marketing campaign to prevent syphilis among men who have sex with men.

OBJECTIVES: We carried out an independent short-term impact evaluation of a social marketing campaign designed to reduce syphilis infections among men who have sex with men in south Florida in 2004. METHODS: Venue-based surveys were conducted shortly after the campaign began and 6 months later to assess changes in exposure to campaign materials, awareness, knowledge about syphilis, perceptions of risk, sexual behavior, clinic visits, and testing and treatment for syphilis among participants. RESULTS: Exposure to social marketing campaign materials increased from 18.0% at baseline to 36.5% at follow-up (P< .001). Awareness of syphilis and perceptions of risk increased among Broward County residents but not among Miami-Dade County residents. Risky sexual practices and patterns of recreational drug use did not change. No significant increases in knowledge, clinic visits, or testing or treatment for syphilis among participants were detected over the 6-month study period. CONCLUSIONS: None of the campaign objectives were fully met. The interventions were insufficient to produce a significant impact among men who have sex with men in south Florida.

Risky sexual behaviors associated with recreational drug use among men who have sex with men in an international resort area: challenges and opportunities.

South Florida is home to a highly transient population of approximately 145,000 men who have sex with men (MSM) and annually hosts over 1.8 million gay and bisexual visitors. To develop more effective interventions for HIV/sexually transmitted infections (STI) prevention in this setting, we conducted a cross-sectional study of recreational drug use and risky sexual behaviors among MSM. A standardized, self-administered questionnaire, reviewed and approved by a university Institutional Review Board, was offered to men 18 years of age and older who reported ever having sex with a man. Men were approached on weekends in five diverse locations in Miami-Dade County and five in Broward County in winter 2004. An honorarium of $10 was offered to those who completed and returned a questionnaire. Of 407 participants, 115 men (28%) lived in Miami-Dade, 147 (36%) lived in Broward, 46 (11%) lived in another county in south Florida, and 99 (24%) lived elsewhere. Overall, 32% reported using one or more "club drugs" in the past year. Club drug use was highly associated with unprotected anal intercourse (UAI) (P < .001). MSM residing outside of south Florida were more likely than local residents to report using cocaine and ketamine and engaging in unprotected receptive anal intercourse (URAI) in the past month (P = .03). Tourists may be even more likely than residents to engage in risky sexual behaviors and use certain recreational drugs. Interventions must be developed, implemented, and evaluated that take into account the unique characteristics of international resort areas.
