- Abstract Introduction An association between pollen count (Poaceae) and symptoms is well known, but to a lesser degree the importance of priming and lag effects. Also, threshold levels for changes in symptom severity need to be validated. The present study aims to investigate the relationship between pollen counts, symptoms and health related quality of life (HRQL), and to validate thresholds levels, useful in public pollen warnings. Material and methods Children aged 7–18 with grass pollen allergy filled out a symptom diary during the pollen season for nose, eyes and lung symptoms, as well as a HRQL questionnaire every week. Pollen counts were monitored using a volumetric spore trap. Results 89 (91%) of the included 98 children completed the study. There was a clear association between pollen count, symptom severity and HRQL during the whole pollen season, but no difference in this respect between early and late pollen season. There was a lag effect of 1–3 days after pollen exposure except for lung symptoms. We found only two threshold levels, at 30 and 80 pollen grains/m3 for the total symptom score, not three as is used today. The nose and eyes reacted to low doses, but for the lung symptoms, symptom strength did hardly change until 50 pollen grains/m3. Conclusion Grass pollen has an effect on symptoms and HRQL, lasting up to 5 days after exposure. Symptoms from the lungs appear to have higher threshold levels than the eyes and the nose. Overall symptom severity does not appear to change during the course of season. Threshold levels need to be revised. We suggest a traffic light model for public pollen warnings directed to children, where green signifies “no problem”, yellow signifies “can be problems, especially if you are highly sensitive” and red signifies “alert – take action”.

- Introduction: Respiratory allergic disorders like rhinitis and asthma are common conditions that not only affect target organs, but complicate the daily life of affected children and adolescents. Objectives: The aim of this study was to investigate the QoL (quality of life) in children with grass pollen allergy in and out of grass pollen season. Methods: We used the Pediatric Allergic Disease Quality of Life Questionnaire (PADQLQ), a disease-specific questionnaire including both asthma and rhinitis symptoms. We also used the DISABKIDS (a European project which aims at enhancing the quality of life and the independence of children with chronic health conditions and their families) questionnaire, a generic questionnaire covering non-organ-specific effects of disease. Results: Ninety-eight children 718 years old with grass pollen allergy were included. Eighty-nine children (91%) completed the study. The QoL was significantly decreased during pollen season assessed both with DISABKIDS and PADQLQ. The correlation between the questionnaires was 0.73. Not only the physical domain score (P=0.00093) but also the emotional domain score (P=0.034) was significantly lowered. Children with multiple manifestations (asthma and rhinitis) had lower QoL than children with rhinitis alone (P=0.01). Multiple regression analysis showed a highly significant impact on QoL for symptoms from nose, eyes and lungs. They were equally important (standardized coefficient 047, 0.47 and 0.46, respectively). Conclusion: The QoL in children and adolescents with respiratory allergy deteriorates during pollen season. This was shown both with generic (DISABKIDS) and disease-specific instrument (PADQLQ).

- Aim: The aim of the study was to translate and validate the PADQLQ (Pediatric allergic disease quality of life questionnaire), a disease specific quality of life questionnaire for the assessment of quality of life in children with pollen allergy. Methods: The PADQLQ was translated into Swedish according to guidelines. Children 7-18 years with grass pollen allergy were included. Quality of life was assessed in parallel with ordinary symptom scales (VAS) before, during and after the pollen season. Results: 98 children were included. 89 (91%) completed the study. The Results for PADQLQ showed good cross-sectional and longitudinal validity. The retrospective estimation after the season showed good consensus with the assessment during pollen season. Conclusion: Quality of life in children assessed with the PADQLQ (Pediatric allergic disease quality of life questionnaire), is a reliable strategy for evaluating the burden of disease in children with pollen allergy and for the evaluation of treatment.
