The effects of violence exposure on the risk of self-harming behaviors of youth in low- and middle-income countries is not well-understood. Using household survey data from one nationally representative sample and one sample from conflict-affected areas, we examined violence exposure and self-harm among Colombian youth aged 13-24. Survey-weighted prevalence ratios comparing self-harming behaviors by exposure to violence were estimated with Poisson log-linear models, controlling for age, sex, education and food insecurity. Compared to unexposed youth, those exposed to violence in both home and community settings were 7.97 (95% confidence interval [CI]:2.72-23.36) times more likely in the conflict-affected sample, and 21.05 (95% CI: 8.80-50.34) times more likely in the national sample to report having attempted suicide. Among Colombian youth, exposure to violence as either witness or victim was associated with greater prevalence of self-harming behaviors. Youth suicide prevention programs can address exposures to violence as a risk factor for self-harm.
