Lung function norms in healthy working women

Two hundred seventy four healthy working women subjects representing different states were subjected to pulmonary function testing to establish linear multiple regression model. Lung functions were considered as dependent variables while age, height and weight as independent variables. Highly significant negative correlation of all lung function parameters with age and positive correlations with height and weight were observed. Females showed a decline of 0.203, 0.199 and 0.210 litres per decade in FVC, FEV0.75 and FEV1.0 parameters respectively. An increase in FVC, FEV0.75 and FEV1.0 values was found to be 0.0217, 0.0132 and 0.0178 litres respectively per unit centimeter increase in height.
