Abstract
This study was performed to develop a Kdiet-index based on the definitions and characteristics of traditional Korean food. The Korean Food Pattern Index (Kdiet-index) for diseases was applied using dietary data from the 2017 National Health and Nutrition Examination Survey (KNHANES) and the association between Kdiet-index and metabolic disease was confirmed. The study subjects were 1,971 Korean adults aged >40, and the components were classified according to 14 criteria used to establish the Kdiet-index. Main ingredients up to the top 3 were designated using dish names, ingredients, and contents using KNHANES dietary data. Kdiet-index was classified using scores of ≤3 points, 4-7 points, and ≥8 points and total Kdiet-index were calculated by summing dietary scores. Correlations between Kdiet-index and obesity, hypertension, hyperlipidemia, and diabetes were analyzed. The odds ratio (OR) and 95% confidence interval (CI) for obesity were 0.531, 0.385~0.732 and for elevated cholesterol (≥240 mg/dL) indices were 0.471, 0.282~0.788, respectively, which showed a significant decreased in the risk for each disease for Kdiet-index of ≥8 points. This study confirms that metabolically related clinical results improved significantly as Kdiet-index increased and that higher Korean food pattern indices are associated with lower risks of metabolic disease
