[Sexual behaviors and acceptability of STI (including HIV) testing outside nightclubs in Saint-Gilles, Reunion].

The CDAG/CIDDIST centers (CDAG: Free Anonymous Testing Center/CIDDIST: STI Information, Testing and Diagnosis Center) were created in response to the demands of a population at risk of contracting sexually transmitted infections (STIs) wanting to undergo free, anonymous and confidential testing. On the occasion of Sidaction 2010, a study based on a sample of 100 individuals leaving nightclubs in Saint-Gilles (Réunion) was conducted to evaluate the effectiveness of mobile interventions (i.e. measures to promote HIV and STI information, prevention and testing) beyond the confines of CDAG/CIDDIST centers, focusing specifically on at-risk populations. Data were collected on the acceptability of the intervention and HIV/STI testing and on sexual behaviors among the studied population. In addition to STI-related information, participants were offered a more in-depth consultation with a doctor, followed, if necessary, by a test (blood sample). The results show that there was significant interest in the new measures among the population. 77% considered them necessary. 43% intended to come to the information and testing stand for contraceptives. A small proportion of participants (15%) completed the full screening process in situ. In addition, among the studied population (which included individuals with high-risk behaviors), 40% had never undergone HIV testing. The study highlighted various sexual risk behaviors. 69% of the participants engaged in unprotected anal intercourse, including 46% of single people (defined as living alone and not in a stable relationship). The two indicators (i.e. acceptability of local interventions outside CDAG/CIDDIST centers and risk behaviors among the targeted population) suggest the need to pursue "extramural" interventions among targeted populations and to promote them widely.
