Abstract

Background: Patients with chronic obstructive pulmonary disease (COPD) spend higher energy in breathing than healthy individuals. Largely owing tothis, advanced COPD patients are prone to be in a state of undernutrition and thus commonly undergo weight loss during an exacerbation. Thisstudy was designed to statistically assess the association between COPD risk and nutritional intake in Korean patients.
Methods: We analyzed the data of 19,893 individuals aged 40?79 years. The COPD and non-COPD groups were determined based on the results ofpulmonary function test. The dietary intake of the subjects was estimated from nutritional intake survey using a 24-hour dietary recall method.
Logistic regression was used to compare the odds ratio for COPD risk in those who had intake of each nutrient between two conditions, above theestimated average requirement (EAR) and below the EAR.
Results: The COPD group showed significantly lower level of intake of most nutrients, including protein, fat, vitamins, and minerals. The proportion ofundernutrition state defined by nutrient intake below the EAR was higher in the COPD group than in the non-COPD group. Therefore, we found asignificant reduction in COPD risk in a group taking vitamin C above the EAR compared to those taking vitamin C below the EAR.
Conclusion: Our study provides solid statistical evidence for the tendency of less intake of nutrients in the COPD group compared to the non-COPDgroup in Korea. The statistical analyses of the beneficial effect of each nutrient revealed that antioxidants, particularly vitamin C, appeared to beassociated with decrease risk of COPD.
