Effect of parental smoking and social class on the children's pulmonary function

ABSTRACT

The effect of social class and parental smoking on forced expiratory volume in one second [FEVI], forced vital capacity and peak expiratory flow rate [PEFR] of children has been analyzed. Parental smoking did not appear to affect the children's pulmonary function. Furthermore, no significant difference in FEV1 and FVC values have been observed between children of the high and low social classes, but children of the low social class outperformed those of the high social class in PEFR values
