Objective: To measure the effects of aging on lung function parameters in elderly population aged 60 years and above. Methods:The present study was undertaken on elderly population aged 60 years and above. One hundred sixty subjects were selected for the study and all of them had undergone physical and clinical examination along lung function tests. The parameters chosen were FVC, FEV1, FEV3 and PEFR. The data was analyzed using SPSS version 17.0. Mean and standard deviation (SD) was calculated. Results:The mean value of lung function parameters in elderly male and female subjects was significantly correlated with both height and age of the subjects. The mean scores of predicted lung function in male participants were significantly higher compared to females. Conclusion:The study revealed that all lung function indices of study subjects were significantly related to age and height.
