BACKGROUND AND PURPOSE. Peer norms influence the adoption ofbehavior changes to reduce risk for HIV (human immunodeficiencyvirus) infection. By experimentally intervening at a communitylevel to modify risk behavior norms, it may be possible to promotegeneralized reductions in HIV risk practices within a population.METHODS. We trained persons reliably identified as popular opinionleaders among gay men in a small city to serve as behavior changeendorsers to their peers. The opinion leaders acquired socialskills for making these endorsements and complied in talkingfrequently with friends and acquaintances. Before and afterintervention, we conducted surveys of men patronizing gay clubsin the intervention city and in two matched comparison cities.RESULTS. In the intervention city, the proportion of men whoengaged in any unprotected anal intercourse in a two-month perioddecreased from 36.9 percent to 27.5 percent (-25 percent frombaseline), with a reduction from 27.1 percent to 19.0 percent(-30 percent from baseline) for unprotected receptive anal intercourse.Relative to baseline levels, there was a 16 percent increasein condom use during anal intercourse and an 18 percent decreasein the proportion of men with more than one sexual partner.Little or no change was observed among men in the comparisoncities over the same period of time. CONCLUSIONS. Interventionsthat employ peer leaders to endorse change may produce or acceleratepopulation behavior changes to lessen risk for HIV infection.
