We examined suicidal ideation factors among Korean youth. Methods: For risk factor identification, data from the 2008 and 2018 Korean Youth Panel Survey were analyzed (n =6,568) using univariate multiple logistic regression analysis. Negative life events, feelings of hopelessness, early-life adversity, alcohol consumption, smoking, counseling experience, perceived stress, and current health status were independent variables, whereas suicidal ideation was the dependent variable. Results: Proximal (negative life events and feelings of hopelessness), distal (early-life adversities significantly influenced suicidal ideation), and health-related (alcohol consumption, counseling experience, perceived stress, and current health status) factors significantly influenced suicidal ideation among Korean youth. Conclusion: Mental health professionals must include distal risk factors, along with the common proximal and health-related risk factors, to provide targeted interventions. https://ijph.tums.ac.ir/index.php/ijph/article/view/26575 https://ijph.tums.ac.ir/index.php/ijph/article/download/26575/7979
