Correlation of anthropometric parameters with Peak Expiratory Flow Rate


Aims & Objectives: To know correlation between Peak Expiratory Flow Rate (PEFR) and height, weight & BMI in males and females. Material &Method: The study has been carried out on 150 healthy females & males of 18 to 25 years of age. Informed consent was taken. Their PEFR was measured with the help of mini Wrights Peak Flow Meter. Three PEFR readings were taken from each individual and the best of the three readings was considered. Subjects were categorized into groups based on their differences in height, weight and BMI. The variations of PEFR with respect to height, weight and BMI were determined separately. Unpaired t-test and Pearson correlation was used for analysis. Results: The values of PEFR obtained in this study were within the normal range. The mean values of height, weight, BMI and PEFR were higher for males than females. There is also positive anthropometric association with PEFR. Conclusion: It was concluded that PEFR shows positive correlation with anthropometric determinants like height, weight and BMI.
