Correlation between Anthropometric Measurements and Peak Expiratory Flow Rate in Healthy Young Adults
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 2
Abstract
Background: Peak Expiratory Flow Rate is a dynamic lung function test and an accepted index of pulmonary function which is widely used in respiratory medicine. With the unplanned growth of industries and vehicular traffic the environment is getting polluted day by day. As a result respiratory problems have become a common ailment. Respiratory ailments such as bronchial asthma and emphysema have become common even among children Aim: the purpose of this study was to assess the peak expiratory flow rate in adolescents, to correlate the peak expiratory flow rate in boys and girls and to find out the correlation between peak expiratory flow rate and anthropometric measurements such as body weight, height and age. Materials and methods: A cross-sectional survey of student volunteers was conducted A sample of 100 healthy student volunteers comprising 44 boys and 56 girls with ages ranging from 17 to 21 were selected for the study. The following anthropometric measurements were verified in all the individuals – weight, height, BMI,BSA. 1)The participants were weighed on a weighing machine (Edryl India) using light clothing and bare foot. 2)Standing height was measured without shoes to the nearest 0.1 cm using a standard measuring scale.3) BMI was obtained using the following formula. BMI = Weight in Kg/Height in m2 1) BSA was obtained using the Dubois & Dubois formula: BSA = (Weight0.425 x Height0.725) x 0.007184 2) The Wright’s Peak flow meter was used for the measurement of PEFR. Results: The present study done on 100 students (44males and 56 females) shows that there is an excellent correlation between height and PEFR, weight and PEFR and BSA and PEFR. The correlation between PEFR and BMI was less significant Conclusion: In the present study there were no significant differences by gender for any of the correlations. Peak flow is effort dependent. It primarily measures large airway function and muscular effort. Decreased PEF values should be evaluated for consistent patient effort
