title: Health-related quality of life: gender differences in childhood and adolescence.
abstract: OBJECTIVE
  To assess whether gender and age differences can be found in different aspects of health-related quality of life (HRQOL) of children and adolescents, and to what extent these results correspond to theoretical and empirical findings from developmental psychology.
  
  
  METHODS
  A newly developed HRQOL questionnaire was completed by 3,710 youths aged nine to 17 years in seven European countries. The "Kidscreen 52" questionnaire consists of 10 scales operationalising aspects of the physical, psychological and social dimensions of HRQOL. With the use of ANOVA and effect sizes, the influence of age and gender on aspects of HRQOL is reported.
  
  
  RESULTS
  Children report a very good quality of life largely independent of gender. After 12 years, HRQOL decreases in the majority of aspects. In the physical and psychological dimensions, a stronger decrease is found for females than for males.
  
  
  CONCLUSIONS
  Children have higher HRQOL than adolescents in many aspects. With increasing age, HRQOL is frequently worse for females than for males. Examination of the individual aspects leads to a differentiation of the results with relevance for public health.
