The current study examined prevalence and risk factors for suicide ideation in 5038 Lebanese adolescents using Global School Health Survey data. Around 16% of Lebanese adolescents thought of suicide. Multivariate logistic regression models showed that risk factors for suicide ideation included poor mental health (felt lonely, felt worried, felt sad or hopeless), substance use (got drunk, used drugs), victimization (was bullied, was sexually harassed), and lack of parental understanding. Recommendations for future research and interventions are discussed.
