The association between youth violence and mental health outcomes in Colombia: A cross sectional analysis

Violence against children and youth poses public health risks regarding mental health symptoms and substance use. Less studied is the relationship between violence and mental health/substance abuse in the Latin American context. This study explored sex-stratified relationships between violence and mental health/substance use among Colombian youth.We analyzed the 2018 Colombian Violence Against Children and Youth Survey, which collected cross-sectional data from Colombian youth (13-24 years) (n = 2706). Exposure variables were (i) binary sexual, emotional, and physical victimization and (ii) poly-victimization. The outcomes were binary suicidal thoughts, self-harm, past-month psychological distress, binge drinking, smoking, and drug use. Sex-stratified, logistic regressions were adjusted for age, primary school, parental presence, relationship status, and witnessing community violence.For females, (i) emotional violence (compared to being unexposed) was associated with greater odds of suicidal thoughts, self-harm, and psychological distress and (ii) sexual violence was associated with suicidal thoughts and self-harm. For males, (i) emotional violence (compared to being unexposed) was associated with greater odds of suicidal thoughts and psychological distress, but not self-harm and (ii) sexual violence exposure was associated with suicidal thoughts and self-harm. Physical violence was generally not associated with internalized mental health outcomes for females/males, when emotional and sexual violence were held constant. Poly-victimization was consistently and positively associated with internalized mental health symptoms among females, and to a lesser degree for males. Substance use outcomes for males or females were not associated with violence.Findings highlight the internalized mental health burden of emotional and sexual violence.
