Background and Aim: Poor nutrition and low body weight are known factors that contribute to severity of COPD. It is also a significant predictor of survival and mortality in COPD patients. We looked for a possible correlation between BMI and COPD severity by FEV1 and according to COPD GOLD stage. Methods: A random sample of 90 patients attending the COPD clinic were selected and their lung functions were assessed using COSMED Software Version 2013. BMI was assessed using standard methods. This group included a total of 6,11,50,and 23 patients in GOLD stages 1,2,3 and 4 respectively. Data were analysed by MINITAB 17 statistical software. Correlation between BMI and FEV1 percentage was assessed by Pearson's correlation coefficient. An association between COPD GOLD stage and BMI was assessed using ANOVA. Results: The mean BMI of the group was 19.64 kg/m2. The mean FEV1 was 0.926 l and the average of percentage predicted was 40.86%. Pearson correlation coefficient between BMI and percentage predicted of FEV1 was 0.196 and this does not show a significant correlation (p=0.064). One way ANOVA between GOLD stages and BMI, similarly did not reveal a statistically significant result (p=0.629). Conclusion: There was no significant correlation between BMI and COPD stage or the FEV1 demonstrable by statistical analysis. However, this may be due to an over representation of the more severe stages of COPD in this cohort.
