Effect of Neighborhoods and Peer Networks on substance use and violence among adolescents living with and without HIV in India

Purpose of the study: A strong bidirectional association exists between substance use, various forms of violence and HIV. Substance use accounts for 0.8% of the burden of disease measured in disability adjusted life years (DALYs) among adolescents in South Asia. Violence among adolescents living with HIV manifests in various forms including bullying victimization. Little is known about the neighborhood and peer context of adolescent substance use and violence in low middle-income countries. The purpose of the study is to identify peer and neighborhood contexts of substance use and violence among adolescents living with and without HIV in India.
