우리나라 성인의 비타민 A 섭취현황 = 2007~2012년 국민건강영양조사 자료를 이용하여

국문 초록 (Abstract)

본 연구에서는 우리나라 19세 이상 성인의 비타민 A 섭취 실태와 그 역학적 특성을 파악하기 위해 제 4·5기 국민 건강영양조사 (2007~2012) 자료의 24시간 회상법 자료와 상용식품 중 레티놀 및 카로티노이드 함량 데이터베이스를 연계하여 1일 레티놀, 6종의 카로티노이드 (α-카로틴, β-카로틴, 리코펜, β-크립토잔틴, 루테인/제아잔틴) 및 비타민 A 섭취량을 추정하였다. 그 결과 대상자 33,069명의 평균비타민 A 섭취량은 레티놀 당량으로 788.4 μg RE/day였으며, 레티놀 활성당량으로는 488.9 μg RAE/day였다. 대상자의 비타민 A 섭취의 적절성을 평가하기 위해 2010년 한국인 영양섭취기준과 새로 개정된 2015년 한국인 영양소 섭취 기준의 비타민 A 기준과 비교한 결과, 전체 대상자 중 2010년의 RE 기준으로는 42.9%가, 2015년의 RAE 기준으로는 70.6%가 평균필요량 미만으로 섭취하고 있었다. 75세 이상 대상자 중 80% 이상이 새로 개정된 기준에 따르면 평균필요량 미만으로 섭취하고 있었고, 소득 수준이 낮을수록 비타민 A 섭취 부족 위험이 증가하였다. 각 식품군별 비타민 A의 섭취량을 산출하였을 때에는, 채소류, 조미료류, 해조류, 과일류 순으로 기여율이 높았다. 새로 제정된 영양섭취기준에 따라 우리나라 성인의 비타민 A 섭취량을 평가한 결과, 종전에 비해 매우 부족한 것으로 평가되었으므로, 균형 잡힌 식사를 통한 충분한 양의 비타민 A를 섭취하도록 교육하고 권고할 필요성이 대두된다. 본 연구는 우리나라 성인의 비타민 A 섭취량을 추정하고, 섭취의 적절성을 평가한 연구로서 의의가 있으며, 비타민 A의 섭취 실태를 확인한 본 연구에서 더 나아가 우리나라 국민의 비타민 A 및 레티놀, 카로티노이드의 섭취량과 대사지표 및 부족 증상의 발생 등과의 연관성에 대한 후속 연구가 필요할 것으로 사료된다.

Purpose: The purpose of this study was to estimate dietary vitamin A intake and examine major food sources of vitamin A in Korean adults. Methods: Using data from the 2007~2012 Korea National Health and Nutrition Examination Survey, a total of 33,069 subjects over 19-years-old were included in this study. We estimated individual daily intakes of retinol, carotenoids such as α-carotene, β-carotene, β-cryptoxanthin, lutein/zeaxanthin, and lycopene, and vitamin A by linking food consumption data with the vitamin A database of commonly consumed foods. We compared individual vitamin A intakes with the reference value of Dietary Reference Intakes for Koreans. Results: Average dietary vitamin A intakes of study subjects were 864.3 μg retinol equivalent/day (495.7 μg retinol activity equivalent/day) in men and 715.0 μg retinol equivalent/day (403.6 μg retinol activity equivalent/day) in women. Exactly 42.9% and 70.6% of total subjects consumed less vitamin A than the Estimated Average Requirement (EAR) based on retinol equivalent and retinol activity equivalent, respectively. The major food sources of vitamin A were Korean radish leaves, carrot, red pepper, and laver, and the top 20 foods provided about 80% of total vitamin A intake. Conclusion: This study provides basic data for estimation of vitamin A intake in Korean adults. Further research will be needed to analyze the association of insufficient or excess intakes of vitamin A and health problems in the Korean population.
