Hidden dangers among circuit parties - A systematic review of HIV prevalence, sexual behaviors and drug abuse during the biggest gay events

Circuit parties (CP) are extended celebrations, lasting from a day to a week, primarily attended by gay and bisexual men in their thirties and forties. The increasing popularity of circuit parties may play a significant role in the epidemiology of HIV and other sexually transmitted diseases. We performed a systematic literature search in MEDLINE, without any temporal limit, using the term “circuit party”. Only articles reporting cross-sectional studies were analyzed. Ten articles, published in the period from 2001 to 2015 were included in our systematic review and reported data on samples ranging from 173 to 13,883 gay/bisexual men. The HIV prevalence among men who attended the CPs was very high, ranging from 6% to 40.8%. Sexual risk behaviors (e.g. unsafe sex or multiple partners) and drug use were particularly frequent. It wo'uld be useful to promote efficient strategies with the cooperation of party planners, catching the participants before nightlife activities in order to prevent HIV transmission and the use of recreational drugs.
