title: Age and height as predictors of peak expiratory flow rate in Indian girls.
abstract: Peak expiratory flow rate (PEF) was measured on 175 healthy Indian girls in the age range 8-18 years with the help of Wright's Peak Flow Meter. PEF was recorded in the post absorptive phase at least 1 h after breakfast. The subjects rested for 0.5 h before the test procedure and tests were carried out between 1000-11000 hrs to avoid diurnal changes. The highest of three recordings was noted as the subject's PEF. PEF, age, height and body weight were correlated with each other and an intercorrelation matrix between these variables has been designed. It was observed, after performing multivariate regression analysis, that age and height are significant predictors of PEF. A multiple linear regression equation and a nomogram have been constructed for predicting PEF from age and height in young healthy Indian girls.
