We tested the efficacy of a sexual risk-reduction intervention for men in South Africa, where heterosexual exposure is the main mode of HIV transmission. <\/jats:p><jats:p> Methods. Matched-pairs of neighborhoods in Eastern Cape Province, South Africa, were randomly selected and within pairs randomized to 1 of 2 interventions based on social cognitive theory and qualitative research: HIV\/sexually transmitted infection (STI) risk-reduction, targeting condom use, or attention-matched control, targeting health issues unrelated to sexual risks. Sexually active men aged 18 to 45 years were eligible. The primary outcome was consistent condom use in the past 3 months. <\/jats:p><jats:p> Results. Of 1181 participants, 1106 (93.6%) completed the 12-month follow-up. HIV and STI risk-reduction participants had higher odds of reporting consistent condom use (odds ratio [OR]\u2009=\u20091.32; 95% confidence interval [CI]\u2009=\u20091.03, 1.71) and condom use at last vaginal intercourse (OR\u2009=\u20091.40; 95% CI\u2009=\u20091.08, 1.82) than did attention-control participants, adjusting for baseline prevalence. No differences were observed on unprotected intercourse or multiple partnerships. Findings did not differ for sex with steady as opposed to casual partners. <\/jats:p><jats:p> Conclusions. Behavioral interventions specifically targeting men can contribute to efforts to reduce sexual risk behaviors in South Africa. <\/jats:p>","DOI":"10.2105\/ajph.2013.301578","type":"journal-article","created":{"date-parts":[[2014,1,16]],"date-time":"2014-01-16T21:01:07Z","timestamp":1389906067000},"page":"467-473","source":"Crossref","is-referenced-by-count":29,"title":["Cluster-Randomized Controlled Trial of an HIV\/Sexually Transmitted Infection Risk-Reduction Intervention for South African Men"],"prefix":"10.2105","volume":"104","author":[{"suffix":"III","given":"John B.","family":"Jemmott","sequence":"first","affiliation":[{"name":"John B.
