Abstract


Background: Malnutrition is a common finding in COPD. Malnutrition in patients with COPD is associated with an impaired pulmonary status, reduced diaphragmatic mass, lower exercise capacity, and higher mortality rate when compared to adequately nourished individuals with COPD.

Objectives a) To assess the nutritional status measured by BMI and triceps skin fold thickness of COPD patients. b) To correlate the nutritional status with severity of COPD patients.

Methodology - Study Design - Prospective, Observational, Cross sectional study. This study included 38 patients presenting to OPD. History, BMI, triceps skin fold thicknesss were noted. Severity of COPD was assessed according to GOLD guidelines based on airflow limitation.

Results: The mean age was 63.47years. About 21% of the study population was between 40 to 59 years and 79% of study population above 60 years of age.  The study group had mean symptom duration of 3.68 years. The study group had a mean BMI of 21.82 kg/m2. Out of 38 patients 23.6% patients were under weight. 44.7% had normal BMI. 10.5% were overweight and 21% (8 out of 38) were obese. All of the patients in the study population belong to the GOLD 1 and GOLD 2. Simple scatter chart of BMI and COPD severity (assessed by Post FEV1) does not show a significant pattern, implying weak correlation between the variables. Similarly scatter chart for variables COPD severity (assessed by Post FEV1) with triceps skin fold thickness also does not show a significant pattern, however the graph shows distribution of values in the left lower quadrant with outliers, implying weak correlation between the variables.

Conclusion: Malnutrition is important co morbidity in COPD patients. However there is weak correlation between nutritional status (as measured by BMI and Triceps skin fold thickness) and severity of COPD (in mild and moderate COPD).
