Abstract: Introduction: Nutritional status is considered as an independent factor that influences morbidity and frequency of exacerbations in COPD patients. The aim of this study is to evaluate mid-upper arm circumference and body mass index in stable COPD patients and its correlation with severity of COPD. Materials and Methods: 100 Male patients with pre-registered diagnosis of COPD who attended respiratory medicine department OPD were enrolled. Severity of COPD was assessed using spirometry. BMI recorded and FFM (fat free mass) evaluated by measuring MUAC. Results analyzed using SPSS 20.0 software. Results: Mild, moderate, severe and very severe COPD based on spirometry was seen in 24%, 25%, 46%, 15% respectively. 45% of patients had low BMI (21kg/m2) and 62% had decreased FFM (MUAC- <27cm). Decreased BMI and FFM both had significant correlation with severity of COPD. FFM depletion had better correlation than BMI with COPD severity (P value- 0.002) Conclusion: Severity of COPD had strong positive correlation with severity of malnutrition. FFM depletion correlates better with COPD severity than BMI and hence to be considered more significant in planning nutritional supplemental strategies which helps in improving COPD disease prognosis.
