Abstract :

FEV1, BMI and objective assessment of exercise intolerance have proved useful in predicting outcome in cases of COPD. Aims and objectives: To study correlation between Spirometric staging of COPD based on post onchodilator FEV1, BMI and objective assessment of exercise intolerance by 6 minutes walk test. Observation and results: 31 (65.95%) of the patients had a BMI between 15–20.99 Kg/m2. 5 (10.63%) of the patients had BMI below 15. 2 (2.12%) of the patients had BMI more than 25. The mean BMI of the patients included in the study was 19.24 Kg/m2. 17 (36.17%) of patients had a BMI below 18.5 Kg/m2. 21 (44.68%) of the patients included in the study were found to be spirometric stage III COPD. 12 cases (25.53%) were in stage II and 14 cases (29.78%) in stage IV. Most of the patients included in the study [29 (61.70%)] walked a distance between 301–400 metres. Conclusion: BMI and 6MWT are inversely related to the spirometric staging
