Prediction of peak expiratory flow rate from armspan in healthy children aged 8 to 12 years

Abstract

Peak expiratory flow rate (PEFR) was measured in 400 normal healthy school going children in the age group of 8 to 12 years of Lucknow city. It was observed that there was a gradual, parallel progressive increase in the magnitude of arm span, a physical growth parameter and peak expiratory flow rate (PEFR) per year increase in age. A highly significant positive correlation exited between arm span and PEFR to predict PEFR from arm span multiple and partial "Bivariate" prediction equation was calculated.

“…This may be due to the recorded P-values for BMI and age being greater than the 0.05 level of significance. This study is therefore inconsistent with findings by [20] who found a progressive rise in Peak Expiratory Flow Rate (PEFR) and arm span per rise in age in children. They witnessed an increase in the PEFR values with increase in age and arm span.…”
