Dietary Cholesterol Intake in the Korea National Health and Nutrition Examination Survey (KNHANES) VI (2013–2015) / 대한지역사회영양학회지

ABSTRACT

OBJECTIVES: The aim of the study was to assess the intake of dietary cholesterol and its major food sources in the Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: A total of 20,671 nationally representative sample who had 24-hour recall data from the KNHANES VI (2013–2015) was included in this study. Mean cholesterol intake and the prevalence of subjects with cholesterol intake over the Intake Goal of the Dietary Reference Intakes (DRIs) for Koreans were analyzed. Intakes of cholesterol by food groups or each food were calculated to find out the major food sources for cholesterol intake in Koreans. RESULTS: The mean dietary cholesterol intake was 261.3 mg, which was higher in men (303.5 mg) compared to women (219.1 mg). Dietary cholesterol intake and the prevalence of subjects with cholesterol intake over the Intake Goal of DRIs were the highest in the 19-29 year old group. The eggs was the first major food group source for cholesterol intake in all age groups. Major food sources for cholesterol intake among Korean were egg, chicken, pork, squid and beef, which contributed 66.9% to total cholesterol intake. CONCLUSIONS: Although the mean dietary cholesterol intake was under 300 mg, the prevalence of subjects with cholesterol intake over the Intake Goal of DRIs was about 30% in adults. Because both the mean intake and the prevalence of subjects with cholesterol intake over the Intake Goal of DRIs were higher in young adult groups, the dietary cholesterol intake was expected to be increased.
