We examined the efficacy of a brief behavioral intervention to promote condom use among female sex workers in Tijuana and Ciudad Juarez, Mexico. <\/jats:p><jats:p> Methods. We randomized 924 female sex workers 18 years or older without known HIV infection living in Tijuana and Ciudad Juarez who had recently had unprotected sex with clients to a 30-minute behavioral intervention or a didactic control condition. At baseline and 6 months, women underwent interviews and testing for HIV, syphilis, gonorrhea, and chlamydia. <\/jats:p><jats:p> Results. We observed a 40% decline in cumulative sexually transmitted illness incidence (P = .049) in the intervention group. Incidence density for the intervention versus control groups was 13.8 versus 24.92 per 100 person-years for sexually transmitted illnesses combined (P = .034) and 0 versus 2.01 per 100 person-years for HIV (P &lt; .001). There were concomitant increases in the number and percentage of protected sex acts and decreases in the number of unprotected sex acts with clients (P &lt; .05). <\/jats:p><jats:p> Conclusions. This brief behavioral intervention shows promise in reducing HIV and sexually transmitted illness risk behaviors among female sex workers and may be transferable to other resource-constrained settings. <\/jats:p>","DOI":"10.2105\/ajph.2007.130096","type":"journal-article","created":{"date-parts":[[2008,9,18]],"date-time":"2008-09-18T14:42:11Z","timestamp":1221748931000},"page":"2051-2057","source":"Crossref","is-referenced-by-count":105,"title":["Efficacy of a Brief Behavioral Intervention to Promote Condom Use Among Female Sex Workers in Tijuana and Ciudad Juarez, Mexico"],"prefix":"10.2105","volume":"98","author":[{"given":"Thomas L.","family":"Patterson","sequence":"first","affiliation":[{"name":"Thomas L.
