- Objectives
The objective of this study was to develop a zinc database (DB) to estimate the intake levels of zinc in Korean toddlers and preschool children using the data from the Korea National Health and Nutrition Examination Survey (KNHANES).
Methods: A total of 3,361 food items for the DB representing the usual diet of Korean toddlers and preschool children were selected based on KNHANES (2009~2013) and the food composition table of Rural Development Administration (RDA). The existing values of zinc in foods were collected from the latest food composition tables of RDA (9th revision) and the US Department of Agriculture (legacy release). The zinc contents were filled preferentially with these collected values. The missing values were replaced with the calculated values or imputed values using the existing values of similar food items from the data source. The zinc intake levels of Korean toddlers and preschool children were estimated using KNHANES and zinc DB Results: A total of 1,188 existing values, 412 calculated values, and 1,727 imputed values were included in the zinc DB. The mean intake levels of zinc for 1-2-year-old children and 3-5-year-olds were 5.17 ± 2.94 mg/day and 6.30 ± 2.84 mg/day, respectively.There was no significant difference in the zinc intake levels between boys and girls in each group.
Conclusions: This newly developed zinc DB would be helpful to assess the zinc nutritional status and investigate the association between the zinc intakes and related health concerns in Korean toddlers and preschool children.
