- Abstract
- Background: We previously developed the Korean Calcium Assessment Tool (KCAT) for assessing the intake of calcium and vitamin D in Korean women. However, based on the Korea National Health and Nutrition Examination Survey (KNHANES) VI and VII (2013–2018), major food sources for calcium and vitamin D have changed, and the National Standard Food Composition database was updated. Therefore, the present study aimed to update the KCAT and validate the Updated KCAT. Methods: A total of 285 women aged >19 years were asked to complete questionnaires of the KCAT and the Updated KCAT. Results: Calcium intake did not differ significantly between the KCAT (566±245 mg/day) and the Updated KCAT (569±248 mg/day; P=0.343). A correlation coefficient of 0.99 indicated a positive correlation on calcium intake between the KCAT and the Updated KCAT, with an almost perfect agreement by Cohen’s κ coefficients (0.95). Vitamin D intake assessed by the Updated KCAT was significantly higher than that assessed by the KCAT, which was positively correlated with a moderate agreement measured by Cohen’s κ coefficients (0.41). Conclusions: The present study demonstrated that the Updated KCAT was a valid tool for the rapid evaluation of calcium and vitamin D intake for Korean women.
