Study information
Scientific title
An urban community randomised trial of a multicomponent intervention for the prevention of sexually transmitted disease in female sex workers and the general population
Acronym
PREVEN
Study hypothesis
We aim to:
1. Determine the impact of a hybrid intervention on:
1.1. Prevalence of gonococcal, chlamydial, and trichomonal infection and syphilis seroreactivity in high-risk Female Sex Workers (FSW), bridging groups of clients of FSW, and the lower-risk young adult general population
1.2. The antimicrobial susceptibility and virulence-associated phenotypes of N. gonorrhoeae
2. Develop and employ mathematical models of gonorrhoea, chlamydial infection, syphilis and trichomoniasis to explain the observed impact of the interventions, and facilitate transfer of the intervention to other locations

Condition
Sexually transmitted disease prevention
Intervention
Using data from a baseline survey in 24 Peruvian cities with populations more than 50,000, 20 cities were selected for the trial and placed into matched pairs based on region (coastal, jungle or Andean), size and STD prevalence. The pairs were then randomised into control or intervention groups, with the latter receiving a two-year hybrid intervention of:
1. Strengthened syndromic management through a network of physicians and pharmacists
2. STD screening and treatment of FSW
3. Social marketing of condoms
At the end of the two-year intervention, FSW and the young adult general population in all 20 cities will be surveyed again to evaluate its impact.
The anticipated end date of this trial has been extended to the 31st December 2006. The previous anticipated end date was 31/12/2005.
