Relationship Between Antidepressant Medication Treatment and Suicide in Adolescents

TLDR: An inverse relationship between regional change in use of antidepressants and suicide raises the possibility of a role for using antidepressant treatment in youth suicide prevention efforts, especially for males, older adolescents, and adolescents who reside in lower-income regions.

Abstract: Context A decade of increasing antidepressant medication treatment for adolescents and corresponding declines in suicide rates raise the possibility that antidepressants have helped prevent youth suicide. Objective To evaluate the relationship between regional changes in antidepressant medication treatment and suicide in adolescents from 1990 to 2000. Design Analysis of prescription data from the nation's largest pharmacy benefit management organization, national suicide mortality files, regional sociodemographic data from the 1990 and 2000 US Census, and regional data on physicians per capita. Participants Youth aged 10 to 19 years who filled a prescription for antidepressant medication and same-aged completed suicides from 588 three-digit ZIP code regions in the United States. Main Outcome Measures The relationship between regional change in antidepressant medication treatment and suicide rate stratified by sex, age group, regional median income, and regional racial composition. Results There was a significant adjusted negative relationship between regional change in antidepressant medication treatment and suicide during the study period. A 1% increase in adolescent use of antidepressants was associated with a decrease of 0.23 suicide per 100 000 adolescents per year (β= −.023, t = −5.14, P t =−3.81, P t = −3.43, P t = −3.73, P Conclusions An inverse relationship between regional change in use of antidepressants and suicide raises the possibility of a role for using antidepressant treatment in youth suicide prevention efforts, especially for males, older adolescents, and adolescents who reside in lower-income regions.
