Comparative Assessments of Dietary Intake of Korean-Chinese and Koreans

This study was conducted to assess dietary intake and quality obtained by 24-hour recall method between Korean-Chinese in Yanbian, China(Korean-Chinese) and Koreans in Kuri, Korea(Koreans). The subjects consisted of 730 Korean-Chinese and 696 Koreans. Mean daily energy intake of Korean-Chinese was 1,788kcal and that of Korean was 1,844kcal. Proportions of energy intake from carbohydrate, fat, and protein were 62.6: 16.9: 14.2 for Korean-Chinese and 65.4: 16.3: 14.4 for Koreans. Nutrient intake levels of Koreans were higher than those of Korean-chinese in most nutrients. Calcium and vitamin $B_2$ intakes as percent of Korean RDA were less than 60% in Korean-Chinese. Koreans consumed calcium and vitamin A in the level less than 80% of Korean RDA. Iron intake level of Korean females was less than 75% of Korean RDA. Korean-Chinese consumed 90.4% of food from plant origin, and Koreans consumed 82.5% of food from plant origin. Mean dietary diversity score(DDS) of Korean-Chinese, $3.00{\pm}0.39$, was significantly lower than that of Koreans, $3.73{\pm}0.76(p<0.05)$. Mean dietary variety score(DVS) of Korean-Chinese, 13.6, was significantly lower than that of Koreans, 20.1(p<0.001). According to these results, some adults in the both Korean-Chinese and Koreans did not consume enough nutrients, especially calcium and vitamin $B_2$ intake for Korean-Chinese and calcium and vitamin A intake for Koreans. Dietary qualities of Korean-Chinese subjects and Korean females were not adequate. In the future, further research to promote dietary quality of Koreans including Korean-Chinese must consider the results of this study.
