Immigrant-origin Youths at Risk: Trends in Suicidal Behaviors among Korean Adolescents by Immigrant Origins and Ethnic Options (2011–2019)

BACKGROUND:In line with the immigrant paradox, immigrants' health advantages disappear among second-generation immigrant-origin youths, including a high prevalence of suicidal behaviors. Nevertheless, the secular trend in suicidal behaviors among immigrants in South Korea has not been examined. While Korean society was once considered homogeneous, intra-Asian migration has increased in recent decades. It is needed to explore the relationship between ethnic options and mental health outcomes among immigrant-origin youths, including suicidal behaviors.METHODS:Using the nationally representative Korean Youth Risk Behavior Survey from 2011 to 2019 (600,541 non-immigrant-origin and 6,085 immigrant-origin), we examined the rates of suicidal behaviors to identify trends among youths with/without immigrant-origin and depending on the visibility of their immigrant-origin. Then, we conducted logistic regression to examine whether visibility is associated with higher suicidal behaviors among immigrant-origin youths.RESULTS:Overall, suicidal behaviors have declined, but immigrant-origin youths showed higher levels of suicidal behaviors than non-immigrant-origin youths. Visible minority youths showed higher suicidal behaviors than their invisible counterparts, particularly in suicidal planning and suicide attempts. Among immigrant-origin youths, visible minority status was associated with higher suicidal thoughts, plans, and attempts, controlling for socio-economic factors. Furthermore, female immigrant-origin youths show higher suicidal behaviors than their male counterparts.CONCLUSIONS:The results suggest that data disaggregation is needed when examining the mental health of immigrant-origin youths. Practitioners and policymakers should pay particular attention to immigrant-origin youths and recognize that their visibility may be associated with their risk of suicidal behaviors. Targeted intervention is also required for female visible minority youths.
