Other strategies have placed emphasis on structural interventions, which focus more on changing population-level factors, such as the organization of sex work and the prevailing behavioral norms.
Perhaps the most notable example of this approach is the 100% condom campaign instituted in Thailand .
Increasingly, the use of structural/environmental interventions to complement individual-level approaches is being advocated [7, 8].
form of sex work with those of women involved in other types of sex work, in the Indian state of Karnataka Methods Data were gathered through in-person interviews.
Sampling was stratified by district and by type of sex work Results Of 1588 female sex workers (FSWs) interviewed, 414 (26%) reported that they entered sex work through the FSWs had initiated sex work at a much younger age (mean, 15.7 vs.
21.8 years), were more likely to be home based (68.6% vs.
14.9%), had more clients in the past week (average, 9.0 vs.
In this context, they specify 4 levels of risk causation in sex work: societal (superstructural), community (structural), institutional (infrastructure/environment), and individual.
Overs  has categorized 3 levels of intervention strategies for FSWs: individual/cognitive, participation and empowerment, and structural/environmental.This formulation is perhaps less theoretical but still emphasizes the importance of designing programs that address factors at both the individual and the structural/environmental levels, to reduce the vulnerability of FSWs.6.4), and were less likely to migrate for work within the state (4.6% vs.18.6%) but more likely to have worked outside the state (19.6% vs. FSWs were less likely to report client-initiated violence during the past year (13.3% vs. 44.3%) Conclusion Differences in sociobehavioral characteristics and practice patterns between Reducing the vulnerability of female sex workers (FSWs) to sexually transmitted infections (STIs), including HIV infection, is a global public health imperative, owing to both the obligation to protect and promote the health of FSWs and the strategic importance of interrupting transmission to and from this subpopulation as a means of controlling epidemics of STIs and HIV infection [1–3].Various program strategies have been successful for STI/HIV infection prevention among FSWs.Some of these strategies were designed as individual/cognitive interventions through peer outreach and education [4, 5].
