Scottish Health Survey - topic report: lung function

This report presents data from objective measurement of lung function in adults, measured by portable spirometers, using data from the 2008-

2011 Scottish Health Surveys.

a FEV1: Forced expiratory volume in one second; FVC: Forced vital capacity; FEV1/FVC: FEV1 as a proportion of FVC

b No bronchodilator was given in this survey

c This table is based on participants in white ethnic groups only. The Stanojevic All Age 2009 equations, applicable to white (Caucasian) populations, were used to determine the predicted values for spirometry measurements in this chapter. ERS Global Lungs Initiative ethnic-specific reference equations that will also cover other ethnic groups were not available at the time of analysis, and therefore participants from non-white ethnic groups were excluded from the analysis shown here

d Centiles show the position of these parameters within a statistical distribution in a normal (healthy) population. If a parameter is on the 5th centile, this means that for every 100 people, 5 would be expected to be at or below that level and 95 above

e Probable airflow limitation: Both FEV1 and FEV1/FVC below the 5th centile
