The study was undertaken to establish normograms for PEFR in healthy rural south Indian school children and to derive prediction equations for PEFR with height. PEFR was measured in 1403 children aged 5 to 17 years using Wright's mini peak flow meter. Prediction equations were derived for PEFR with height in boys and girls. Normograms were plotted based on the observed values of PEFR in the study population. Significant linear correlation was seen of PEFR with height in males (p < 0.001, r = 0.856) and in females (p < 0.001, r = 0.762). Prediction equation for PEFR are 4.49 x height (cm) - 384.64 in males and 2.99 x height (cm) - 219.44 in females.
本研究旨在建立印度南部农村健康学童的呼气峰值流速（PEFR）正常图表，并推导PEFR与身高的预测方程。使用赖特微型峰值流量计对1403名5至17岁的儿童进行了PEFR测量。推导了男孩和女孩PEFR与身高的预测方程。根据研究人群中PEFR的观察值绘制了正常图表。男性（p < 0.001，r = 0.856）和女性（p < 0.001，r = 0.762）的PEFR与身高之间均存在显著的线性相关性。男性PEFR的预测方程为4.49×身高（厘米）- 384.64，女性为2.99×身高（厘米）- 219.44。
