Quality of life in childhood asthma: use of the Paediatric Asthma Quality of Life Questionnaire in a Swedish sample of children 7 to 9 years old.

To validate a Swedish translation of the Paediatric Asthma Quality of Life Questionnaire (PAQLQ) and to study determinants of asthmatic children's quality of life, seventy-one 7-9-y-old children and their families were approached. Sixty-one children (86%) participated, 36 boys and 25 girls: 11 children with mild, 40 with moderate and 10 with severe asthma. The mean age was 8.7 y. Most commonly restricted activities during the week preceding the investigation were running (74%), gymnastics (30%), walking uphill (26%), playing football (20%) and shouting (13%). Parental rating of symptoms (Spearman's rho = -0.40, p = 0.001), percentage of expected peak flow rate (PEFR) (rho = 0.30, p = 0.009) and physicians' grading (mild, moderate and severe asthma, p = 0.047) all correlated significantly with PAQLQ scores. Younger children reported more impairment of QoL, as did children of parents not sharing household. Sex or presence of eczema or rhinoconjunctivitis did not significantly affect the scores. Children suffering from food allergy scored less impairment of QoL. The instrument was easy to administer, was well accepted by the children and had acceptable internal consistency.
