FEV1, FVC, FEV1/FVC ratio in children of 7-14 years of age from Western Rajasthan
Keywords:Pulmonary Function Tests, FEV1, FVC, FEV1/FVC Ratio, anthropometric
Background: The knowledge of pulmonary function tests (PFTs) is a basic requirement to understand the respiratory physiology for all medical physiologists and clinicians Pulmonary Function Tests provide objective evidence of nature and severity of lung disease.
Objective: To observe FEV1, FVC, FEV1/FVC ratio in healthy male and female school children from 7-14 years of age in Western Rajasthan and to find out the relationship of FEV1, FVC, FEV1/FVC ratio with their height, weight, BSA and sex
Methods: The present study was carried out on 112 male and 76 female children of 7-14 years. For Pulmonary Function Tests, FEV1, FVC and FEV1/FVC along with anthropometric data of each subject was recorded. Data were analyzed by unpaired t test, Pearson correlation coefficient test, simple and multiple regression analysis.
Results: FVC and FEV1 values were found significantly (p<0.001) higher in male than those of female. Significant positive correlation of FVC and FEV1 whereas non significant negative correlation of FEV1/FVC were observed with age, height, weight, body surface area in all children.
Conclusion: As the weight, age, height and BSA of subjects increases, FEV1 and FVC increases while FEV1/FVC ratio decreases in both the sexes.
