Methods: National Integrated Biological and Behavioural Survey (IBBS) 2014-15 has been analysed in the paper. Descriptive statistics and logistic regression analysis were used to understand factors affecting condom use. Propensity score matching (PSM) was done to understand the impact of the TI services on condom use at the last act and consistent condom use in the last three months among FSWs. Results: Younger FSWs aged 15 - 25 years were 1.4 times (95% CI: 1.04 - 1.77) more likely to use consistent condoms in the last three months compared to older over 45 years after controlling for other socio-economic and programme variables. The matched samples estimate ATET i.e. the average treatment effect on treated for consistent condom use in the last three months shows that a 6.0% (CI: 4.7 - 7.3) increase in consistent condom use in the last three months in the FSWs who received information on STI/HIV from peer educator and outreach worker. There is also a 6.0% (4.7 - 7.2) increase in condom use in the last act for FSWs who received the referral services at STI clinics, HIV testing, and detox centres. Conclusions: It is evident that the TI programme has a positive impact on behavior change among FSWs which can prove beneficial to curtail the spread of HIV to the partners and onward transmission to the general population.展开更多
