Overview

Cross-sectional survey reveals high anxiety prevalence and key risk factors in adolescents, highlighting targets for mental health screening.

Key Points

  • Identify prevalence and potential risk factors associated with generalized anxiety disorder among adolescents during the COVID-19 pandemic.
  • Analyzed web-based, self-reported data from the 2020 Korea Youth Risk Behavior Web-based Survey (N=54,890).
  • Evaluated anxiety using the Generalized Anxiety Disorder-7 (GAD-7) questionnaire, defining anxiety as a score of 10 or greater.
  • The overall prevalence of anxiety (GAD-7 score ≥ 10) was 11.2% among the adolescent participants.
  • Anxiety was strongly associated with severe stress (OR = 10.01, 95% CI: 8.40–12.03), depression (OR = 2.78, 95% CI: 2.60–2.97), and perceived unhappiness (OR = 2.30, 95% CI: 2.12–3.11).
  • Significant associations were also observed with internet addiction (OR = 1.97, 95% CI: 1.85–2.10), female gender (OR = 1.29, 95% CI: 1.02–1.09), asthma (OR = 1.21, 95% CI: 1.08–1.37), and pandemic-related financial difficulty (OR = 1.19, 95% CI: 1.11–1.26).
