To measure the Peak expiratory flow rate (PEFR) of healthy school children and to find out the correlation between PEFR values and anthropometric parameters, to create a nomogram of PEFR for children and formulate a regression formula for PEFR.
A cross-sectional study was conducted on healthy school children between the age group of 10 and 16 y, at three higher secondary schools selected in urban area of Jabalpur, Madhya Pradesh. After collecting baseline data, PEFR was measured using mini Wright peak flow meter. The highest of three measurements were recorded for analysis.
Of the 2607 students screened, 2156 were included in the study. Out of which 757 were boys and 1399 were girls. Significant linear correlation was seen in PEFR with height, weight and BMI (r = 0.847, r = 0.750 & r = 0.466 respectively, p < 0.001). Nomograms were plotted based on the observed values of PEFR in the study population. Prediction equations were derived for PEFR with height and weight in boys and girls. Prediction equations for PEFR are -464 + 1.408 × Weight (kg) + 439.192 × Height (m) in boys and -486.544 + 1.064 × Weight (kg) + 462.282 × Height (m) in girls.
Significant correlation was noted between PEFR and anthropometric parameters like height, weight and BMI. Hence, nomogram and formula created can be used in the study area.
测量健康学龄儿童的呼气峰流速（PEFR），并找出 PEFR 值与人体测量学参数之间的相关性，为儿童创建 PEFR 列线图，并制定 PEFR 回归公式。
在马哈拉施特拉邦贾巴尔普尔市区选择的三所高中，对 10 至 16 岁的健康学龄儿童进行了横断面研究。在收集基线数据后，使用迷你 Wright 峰流速计测量 PEFR。记录三次测量中的最高值进行分析。
在所筛选的 2607 名学生中，有 2156 名学生纳入研究。其中，男生 757 人，女生 1399 人。PEFR 与身高、体重和 BMI 呈显著线性相关（r=0.847、r=0.750 和 r=0.466，均 P<0.001）。根据研究人群中观察到的 PEFR 值绘制了列线图。为男生和女生推导了 PEFR 与身高和体重的预测方程。男生的 PEFR 预测方程为-464+1.408×体重（kg）+439.192×身高（m），女生的预测方程为-486.544+1.064×体重（kg）+462.282×身高（m）。
PEFR 与身高、体重和 BMI 等人体测量学参数之间存在显著相关性。因此，可在研究区域使用创建的列线图和公式。
