Ca insufficiency and its related health issue have been important nutritional concerns in South Korea. Utilizing the data of 8,034 adults aged 19‐64 from the Korea National Health and Nutrition Examination Survey (KNHANES 2010‐2011), we selected some food items from the original 63 items in the FFQ of KNHANES to develop a short FFQ‐screening instrument to assess dietary Ca insufficiency and validated the instrument. Through various simulations, 5 food items were selected, divided into three food groups, and ranked in order of priority for Ca intake. They were milk, small bony fish, and dark green vegetables. We divided the subjects into low or high intake groups according to the intake frequency: once a day and over vs. less than once a day for milk and small bony fish, and 4 times a week and over vs. less than four times a week for dark green vegetables. Based on the results, the low milk with low small bony fish and dark green vegetable group was defined as the highest risk group for Ca insufficiency and included 69.4% of the total subjects who consumed less than the estimated average requirement (EAR) for Ca. The low milk but with high small bony fish or dark green vegetable group, the second group at risk of Ca insufficiency, included 16.6% of the total subjects who consumed Ca less than EAR. The high milk but with low small bony fish and dark green vegetable group included 10.5% of the total subjects who consumed Ca less than EAR. The high milk with high small bony fish or dark green vegetable group included just 3.5% of the total subjects who consumed less than EAR for Ca. The short screening instrument may provide quick assessments of Ca insufficiency.
