adolescent suicide-related behaviors may continue to increase in the future. In particular, suicidal ideation and suicide attempts in adolescence have been identified as important predictors of suicidal ideation and suicide attempts in adulthood.21 Therefore, integrated preventive intervention programs targeting the concurrent initiation of alcohol use, cigarette smoking, and sexual intercourse, especially among preteens, should take precedence over those focused on each of these issues separately, thereby reducing the potential risks for subsequent suicidal ideation and suicide attempts.
