Abstract

Since normal values for peak expiratory flow rate (PEFR) were not available for Iranian children, this study was conducted on 1550 normal schoolchildren (772M, 778F) in Tehran, aged 6-14 years, in order to determine these measurements. The mini-Wright peak flow meter was used to measure PEFRs. The highest of three readings was taken as the correct value. The relationship between PEFR, age, weight, height and surface area was studied. PEFR values increased with age, but there was a high correlation between them and studied anthropometric measurements. The male children showed significantly higher values ( P < 0.01 ) of PEFR in comparison to female children, except in the 145-159 cm interval. Regression analysis was used to calculate the predicted normal value of PEFR and also to assess its relationship to age, weight and height. The results were recorded in a nomogram and differences between our findings and other authors compared and discussed. The results would be useful in obtaining predicted normal values in Iranian schoolchildren with pulmonary dysfunction.
