Objective: To establish the normative data of PEFR among school children aged 10–14 years in Ghaziabad city, Uttar Pradesh, India.
Materials and Methods: A cross-sectional study was donein500school childrenaged 10–14yearsin Ghaziabadcity.PEFR wasrecordedwiththeMini-Wright PeakFlowMeter. Anthropometricvariablessuchasage,height,weight,andbodymassindexwererecorded.ResultswereanalyzedbyANOVA with SPSS, version 17.0, using unpaired t test. Result: Results showed that there was an increase in PEFR in boys and girls with an increase in age, height, and weight.
