Health-related quality of life and its relation to chronic diseases and mental health problems among children and adolescents Results from KiGGS Wave 2

Background Health-related quality of life (HRQoL) is increasingly established as an indicator for the subjective health of children and adolescents. The aim of this study was to describe the current HRQoL among children and adolescents in Germany aged between 11 and 17 years taking into account common chronic diseases (bronchial asthma, atopic dermatitis, obesity, ADHD) and mental health problems. Methods The analysis is based on information obtained from 6,599 children and adolescents (51.9% girls; 48.1% boys) from KiGGS Wave 2 (2014-2017). HRQoL was measured with the multidimensional KIDSCREEN-27. The chronic diseases and mental health problems under investigation were assessed by several indicators. Results Differences in HRQoL could be found as a function of age and gender. The HRQoL among girls was lower at an older age across all dimensions. These age-related differences are less pronounced among boys. The HRQoL of children and adolescents with chronic diseases and mental health problems was lower compared to their healthy peer groups. The comparison of the investigated chronic diseases and mental health problems revealed significant differences. Particularly, HRQoL was lower for children and adolescents with obesity and mental health problems. Discussion The distinction of several dimensions of HRQoL allows a comprehensive understanding of age- and gender-related effects and provides a detailed assessment of the impact of chronic diseases and mental health problems. The present findings underline the importance of HRQoL as an indicator for the subjective health of children and adolescents.
