Forced expiratory indices in normal Libyan children aged 6-19 years

Abstract

Forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were measured in 796 Libyan children (386 boys and 410 girls) with ages ranging from 6 to 19 years. Values in girls were significantly less than those in boys after allowance had been made for age and height. FVC and FEV1 correlated best with standing height but were also correlated with body weight. These results may be used as a source of standard values for Libyan children.
