Abstract

Background: Malnutrition is frequently observed in patients with Chronic Obstructive Pulmonary Disease (COPD). However, the effects of decreased caloric consumption on disease severity have not been determined.
Objective: To examine the hypothesis that increased incidence of COPD-related symptoms is associated with lower energy intake in malnourished COPD patients. Design and Setting: A cross-sectional study at a single institute.
Participants: Patients with older than 18 years of age who visited the outpatient COPD clinic at a single institute were eligible. Measurements: Subjects were divided into two groups to categorize high and low Daily Energy Intake (DEI) using three strategies, with daily caloric cutoff thresholds of 25, 30 and 35 kcal/kg to distinguish high-DEI patients from low-DEI patients. All data was compared between higher- DEI and lower-DEI patients using each threshold to examine whether lower energy intake is associated with COPD symptom severity and frequency and to determine the optimal cutoff value to distinguish higher-DEI and lower-DEI patients.
Results: The cutoff value of a DEI of 30 kcal/kg could identify which patients had severe symptoms and malnutrition. COPD patients with DEI ≤ 30 kcal/kg had more severe dyspneic symptoms, as determined by a COPD Assessment Test (CAT). Finally, CAT could be recognized as the determinant of lower DEI in patients with COPD and malnutrition.
Conclusion: Our study proved that DEI ≤ 30 kcal/kg body weights may identify COPD patients with severe dyspnea, as assessed by CAT. In addition, the Food Frequency Questionnaire, known as BDHQ (brief-type self-administered diet history questionnaire), suggested that lower-DEI patients consumed a significantly smaller percentage of fat as a macronutrient in total energy. Increasing DEI to greater than 30 kcal/kg per day and increasing fat intake may improve COPD. However, the adverse events from this nutritional strategy must be monitored long term.
