EVALUATION OF EFFECT OF AGEING ON PULMONARY FUNCTION TEST- A CLINICAL STUDY
Raj Kumar Singh

Background: Ageing process causes progressive constriction of the homeostatic reserve of organ. The present study was conducted to evaluate the effect of ageing on lung function test. Materials & Methods: This was a cross-sectional study conducted on 100 subjects divided into five age groups.  Age group I - 21-30 years, age group II- 31-40 years, age group III- 41-50 years, age group IV- 51-60 years and age group V- 61-70 years. Each group contained 20 subjects. We evaluated FVC, FEV1, PEFR, FEV1/FVC, SVC and MVV in all groups. Results: The mean of BMI, dyspnoea and physical activity level in all groups. As the age advanced there was decrease in BMI. Measurement of dyspnoea increased with advancing age while there was significant decrease in physical activity level in age group IV and V (P<0.05). We measured FVC, FEV1, PEFR, FEV1/FVC, SVC and MVV in all groups. There was decrease in all lung function values as age advanced. We compared the mean of FVC, FEV1, PEFR, FEV1/FVC, SVC and MVV in all groups. The difference was statistical significant in all (P<0.05) except FEV1/FVC where it was non significant (P>0.05). The values of all lung functions are negatively correlated with age which shows that lung functions significantly decline with age. Conclusion: Ageing process causes progressive constriction of the homeostatic reserve of organ. There is decline in all lung functions with the advancing age.
Key words: Ageing, dyspnoea, pulmonary function test
