Effect of BMI & WC on severity of COPD patients

Abstract

Introduction: COPD is the major cause of morbidity and mortality worldwide. The link between COPD and BMI is subject of interest for many years.Waist  circumference  is  also  important anthroprometric  profile which should be measured in COPD patients. Therefore we plan to study  status of BMI & Waist circumference in patients of COPD & correlate both with its severity.Method:We did an observational study on 100 COPD patients from April 2019 to June 2020 in medicine department , SSMC& SGMH Rewa.Observation and results: Most of patients (80%) in underweight category coming under more severe group with significant p value of 0.01 More than 70 % patients in obese category coming in less severe group. 72% the patients with central obesity were falls under more severe group (GOLD 3&GOLD 4) & 70% of patient without abdominal obesity were in less severe group (GOLD 1&GOLD 2) with statistically significant p value of 0.00039.Conclusion:COPD  isassociated with Body Mass Index. COPD  severity found to inversely related to BMI. These novel findings support Obesity Paradox..But highly significant negative association found between waist circumference and FEV1.
