Mental Health and Health-Related Quality of Life in Austrian Adolescents with Chronic Physical Health Conditions: Results from the MHAT Study.

Chronic physical health conditions (CPHC) are on the rise in younger age groups and might have a negative impact on children and adolescents. In a representative sample of Austrian adolescents aged 10-18 years, internalizing, externalizing, and behavioral problems were assessed cross-sectionally using the Youth Self-Report and health-related quality of life (HrQoL) using the KIDSCREEN questionnaire. Sociodemographic variables, life events, and chronic illness specific parameters were considered as associated variables with mental health problems in individuals with CPHC. Of 3469 adolescents, 9.4% of girls and 7.1% of boys suffered from a chronic pediatric illness. Of these individuals, 31.7% and 11.9% had clinically relevant levels of internalizing and externalizing mental health problems, respectively, compared to 16.3% and 7.1% adolescents without a CPHC. Anxiety, depression, and social problems were twice as high in this population. Medication intake due to CPHC and any traumatic life-event were related to mental health problems. All HrQoL domains were deteriorated in adolescents with a double burden of mental and CPHC, whereas adolescents with a CPHC without mental health problems did not differ significantly from adolescents without a chronic illness. Targeted prevention programs for adolescents with a CPHC are urgently needed to prevent mental health problems in the long term.
