Background: The present study examined the association between 9/11-related adolescent behavioral problems on mental health outcomes in early adulthood.
Methods: Data from enrollees of the World Trade Center Health Registry, who completed at least one adolescent (2006-2007 or 2011-2012) and adult survey (2011-2012 or 2015-2016), were analyzed. Adolescent behavioral difficulties were assessed using the adolescent-reported Strengths and Difficulties Questionnaire (SDQ). Adult mental health outcomes included binge drinking, smoking status history, 9/11-related post-traumatic stress disorder (PTSD), depression, and the self-reported number of physician mental health diagnoses. Multivariable regression was used to estimate associations of SDQ scores with mental health outcomes.
Results: Of the 297 enrollees, 16.8% (n = 50) had abnormal/borderline SDQ scores as an adolescent. Binge drinking was not associated with adolescent SDQ scores. Enrollees with abnormal/borderline SDQ scores as an adolescent were more likely to be a consistent smoker (odds ratio (OR): 5.6, 95% confidence interval (CI): 1.2-25.2), have probable PTSD (OR: 3.5, 95% CI: 1.3-9.8), depression (OR: 6.2, 95% CI: 2.7-13.9), and to have two or more self-reported physician-diagnosed mental health conditions as an adult (OR 5.6, 95% CI: 2.0-12.5).
Conclusions: The findings of this study underscore the need to intervene early with children exposed to traumatic events so as to avert later adolescent and adult problem behaviors.
