Prevalence and predictors of sex under the influence of psychoactive substances among young people in informal settlements in Kampala, Uganda.

Background: The use of psychoactive substances such as alcohol, heroin and marijuana is associated with negative health outcomes such as sexual violence and unintended pregnancies, and risky sexual behaviours. Although there is evidence linking psychoactive substance use and risky sexual behaviours such as inconsistent condom use and multiple sexual relationships, there is limited data on sex under the influence of psychoactive substances among young people. This study aimed to investigate the prevalence and predictors of sex under the influence of psychoactive substances among young people in informal settlements in Kampala, Uganda.
