Mental Health of Adolescents Exposed to the War in Ukraine.

IMPORTANCE: With exposure to traumatic events and reduced access to mental health care, adolescents of Ukraine during the Russian invasion since February 2022 are at high risk of psychiatric conditions. However, the actual mental health burden of the war has scarcely been documented.

OBJECTIVE: To investigate the prevalence of a positive screen for psychiatric conditions among adolescents amidst the ongoing war in Ukraine as well as their associations with war exposure.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study reports the results from the first wave of the Adolescents of Ukraine During the Russian Invasion cohort, the largest cohort study on Ukrainian adolescents' mental health during the Russian invasion since 2022. Using self-reported questionnaires, the national-level prevalence of a positive screen for various psychiatric conditions was estimated among adolescents aged 15 years or older attending secondary school in Ukraine in person or online (including those residing abroad but attending Ukrainian secondary school online) and the prevalence among Ukrainian adolescents living abroad due to the war.

EXPOSURE: Self-reported exposure to war.

MAIN OUTCOMES AND MEASURES: A positive screen for psychiatric conditions. The association between self-reported war exposure and a positive screen for each of the psychiatric conditions was also evaluated.

RESULTS: A total of 8096 Ukrainian adolescents (4988 [61.6%] female) living in Ukraine or abroad were included in the analyses. Based on national-level estimates, 49.6% of the adolescents were directly exposed to war, 32.0% screened positive for moderate or severe depression, 17.9% for moderate or severe anxiety, 35.0% for clinically relevant psychological trauma, 29.5% for eating disorders, and 20.5% for medium risk or higher of substance use disorder. The burden of psychiatric symptoms was similarly large among Ukrainian adolescents living abroad. Adolescents exposed to war were more likely to screen positive for depression (prevalence ratio [PR], 1.39; 95% CI, 1.29-1.50), anxiety (PR, 1.62; 95% CI, 1.45-1.81), clinically relevant psychological trauma (PR, 1.41; 95% CI, 1.32-1.50), eating disorders (PR, 1.21; 95% CI, 1.12-1.32), and substance use disorder (PR, 1.11; 95% CI, 0.98-1.25).

CONCLUSIONS AND RELEVANCE: The findings of this study suggest that the mental health burden of Ukrainian adolescents amidst the Russian invasion of Ukraine is substantial. Mental health care efforts to alleviate the mental health burden of Ukrainian adolescents are needed.
