Abstract

Purpose: The objective of this study was to develop a fatty acid database (DB) for estimation of intake levels of fatty acids in the Korean population, using data from the Korea National Health and Nutrition Survey (KNHANES). Methods: Analytical values of fatty acids in foods were collected from food composition tables of national institutions (National Fisheries Research & Development Institute, Rural Development Administration), Japan Ministry of Education, Culture, Sports, Science and Technology, US Department of Agriculture, and journal articles that previously reported analytical fatty acid content of some Korean foods. The coverage of fatty acids was C14:0, C16:0, C18:0, C18:1, C18:2 n-6, C18:3 n-3, C20:5 n-3 (EPA), C22:6 n-3 (DHA), SFA, MUFA, and PUFA (n-3, n-6, n-9). The fatty acids DB covered a total of 5,144 food items used in the KNHANES nutrition survey. The food items were preferentially filled with analytical values of the collected data source. An analytical value for each food item was selected based on the priority criteria and the quality evaluation of data sources. Missing values were replaced with calculated or imputed values using the analytical values of similar food items from the data source. Results: A total of 1,545 analytical values, 2,589 calculated values, and 1,010 imputed values were included in the fatty acid DB. The developed fatty acid DB was applied to 2,112 food items available for 2011 KNHANES data. Mean intake levels of total fatty acids and saturated fatty acids were 40.3 g/day and 13.2 g/day, respectively. The estimation of total fatty acid intake was 84.3% (men 83.2%, women 86.0%) of daily total fat intake. Conclusion: This newly developed fatty acid DB would be helpful in determining the association of fatty acids intake and related health concerns in the Korean population.

본 연구에서는 국가적 수준에서 지방산 섭취량을 추정할 수 있도록 국민건강영양조사에서 사용하는 식품목록에 수록된 5,144개의 식품에 대해 지방산 DB를 구축하고, 그 과정을 단계별로 정리하여 향후 개정에 활용할 수 있도록 하였다. 지방산 DB는 국내 국립기관에서 발행한 식품의 지방산 함량 분석 자료를 기본으로 하여, 국외의 권위 있는 기관에서 발간한 자료와 학술지에 보고된 함량 분석 자료를 수집한 후 자료의 질을 검토하고 대체하거나 계산하는 방법으로 구축되었다. 구축된 DB를 2011년 국민건강영양조사 자료에 적용하여 지방산 섭취량을 추정한 결과, 총 지방산 섭취량은 지방섭취량의 84% 수준으로 학술지에 보고되고 있는 섭취량 추정수준보다는 높은 수준이나 DB 구축과정에서 확인된 문제점들을 보완하여 자료의 질을 향상시키는 것이 필요할 것으로 사료된다. 본 연구는 관련 연구 분야와 국가 영양정책의 중요한 기본 자료를 확보하였다는데 의의가 있다.
