P6.068 Effect of an HIV Prevention Program Among Female Sex Workers on the Decline in Syphilis Prevalence Among Their Clients in South India
2013
Objective As a part of evaluating the Avahan Programme, two rounds of integrated biological and behavioural assessment (IBBA) surveys were conducted in 2006–07 and 2009–10 among clients of female sex workers (FSWs) across 17 districts in south India to measure the prevalence of HIV and STIs, and related risk factors (n∼7,000 per round). We examined the association between changes in programme indicators and changes in syphilis prevalence. Methods Using a random-effect multilevel logistic regression, we examined the effect of district-specific programme indicators for FSWs (from the Avahan computerised monitoring system) on the decline in syphilis prevalence among clients of FSWs after controlling for significant individual level variables. Program indicators included their 2006 value, the difference in their values between the surveys, and the interaction between the latter and study round. The model also controlled for baseline syphilis prevalence and its interaction with survey rounds. Results Syphilis prevalence among clients of FSWs decreased from 4.8% (round 1) to 2.6% (round 2; p Conclusions The results support that the Avahan intervention among FSWs had a significant impact in reducing syphilis prevalence among their clients in settings covered by the intervention. The triangulation of our results with those obtained among FSWs suggests a major impact of this intervention on the HIV/STI epidemic in southern India.
