Nutrient intake and dietary quality of Korean adults according to chronic obstructive pulmonary disease (COPD): Based on the 2012~2014 Korea National Health and Nutrition Examination Survey / 한국영양학회지

ABSTRACT

PURPOSE: Food intake of COPD patients decreases because of appetite loss, depression, and breathing problems while eating, which increase the likelihood of patients becoming malnourished. This study investigated the nutrient intake and dietary quality of people with and without COPD in Korea. METHODS: There were 2,160 adults aged 50 and over who participated in the 5~6th Korea National Health and Nutrition Examination Survey. The subjects were divided into the COPD group and non-COPD group according to the rate of forced expiratory volume at 1 second (FEV1) against forced vital capacity (FVC). Consumption of food and nutrients were calculated based on the nutrition examination survey. Statistical analyses were conducted using SPSS 19.0. RESULTS: Among individuals in their 50s, intake of vitamin B1 in the COPD group was significantly less than the NCOPD group, while intake of sodium in the COPD group was significantly greater than the NCOPD group. Among individuals in their 60s, the energy intake of the COPD group was significantly less than that of the NCOPD group. The COPD group showed significantly less intake of vitamin B1 and vitamin C, but greater intake of sodium than the NCOPD group. In the group aged 70 and over, The COPD group had significantly less intake of vitamin B1 than the NCOPD group and showed lower nutrient adequacy ratio values in protein, vitamin B1, vitamin B2, and iron than the NCOPD group. CONCLUSION: The COPD group consumed less energy and certain nutrients, and their dietary quality was poor compared to the NCOPD group. Thus, more detailed research is required to understand the concrete relationship between COPD and malnutrition.
