    Abstract:
    The diagnosis of lung function impairments in childhood is based on a variety of reference values. The assessment of "normal" function and growth of lung and airways in pediatric and environmental investigations is biased. The detection of small airway disease at an early stage is based on flow volume measurements, however, reference values in Europe relied on small and highly selected groups of children. We examined 18,106 children and adolescents aged 6 to 16 years at their schools by standardized methods. After exclusion of children with poor cooperation, respiratory signs or symptoms and active smokers, regression analysis was applied for FVC, FEV1, PEF, MEF75, MEF50, MEF25, and MMEF predicted from standing height, sex, age and weight. Means and standard deviations (SD) of lung function parameters of healthy Austrian school children are presented as a basis for reference. Individual lung function can thus be evaluated in SD-scores. Flow measures representing small airway functions were found higher in adolescent girls. MEF25 showed the highest variability unexplained by anthropometric characteristics. The new reference values improve available tools for early detection of respiratory diseases and dysfunctions in children and adolescents and they should help to evaluate environmental and other factors influencing function and growth of lung and airways.
