Baseline spirometry and parental questionnaire data from schoolchildren in Pilot 5

This dataset contains baseline spirometry measurements and corresponding parental questionnaire data collected from schoolchildren participating in Pilot 5 of the K-HEALTHinAIR project. The dataset includes the first spirometry assessment conducted with the participating schoolchildren and a questionnaire completed by their parents prior to this initial assessment. The questionnaire provides additional information relevant to the interpretation of the spirometry measurements. The data originate from the participating study sites in Austria and Poland. This dataset covers the baseline assessment only. Data from subsequent spirometry assessments and the second parental questionnaire will be made available separately at a later stage. The dataset is intended to support research on respiratory health in school-aged children and related factors.
