Medical Journal of Malaysia 1993, 48 (2): 171-4
We conducted a study to measure the peak expiratory flow rate (PEFR), forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) in a group of normal Malay primary school children aged 7 to 12 years. PEFR was measured in 920 children (482 boys and 438 girls) while FVC and FEV1 were measured in 292 of them (168 boys and 124 girls). In agreement with previous studies, we found that PEFR was correlated with age and height of the subjects but FVC and FEV1 were correlated with height only. Prediction equations for all 3 lung function indices for Malay boys and girls were formulated. In comparison with the lung function values from Western and Chinese subjects, the lung function values in our subjects are lower.
