HIV/AIDS Knowledge and Behavioural Change Among Migrant Workers: Evidence from a Cross-Border Intervention in India, Bangladesh, and Nepal

This paper evaluates the Enhancing Mobile Populations’ Access to HIV and AIDS Services, Information and Support (EMPHASIS) programme implemented by CARE International across Bangladesh, India, and Nepal. Using individual-level data, we estimate the programme’s impact on HIV-related knowledge and preventive behaviours among migrant workers. Results show that participation in EMPHASIS significantly increased correct knowledge of HIV transmission, reduced misconceptions, and improved partner communication. These informational gains translated into higher condom use and fewer unsafe sexual practices, with stronger effects among women. The findings provide evidence that peer-led, information-based interventions can improve health behaviours among mobile populations. Integrating such approaches with gender empowerment and mobile health services offers a promising model for addressing HIV vulnerability in cross-border migration settings.
