여대생에서 비타민 A 섭취 현황 및 급원식품 조사

Abstract

The purpose of this study was to estimate the daily intake of vitamin A in Korean female university students. Vitamin A intake was estimated using an inconsecutive 3-day dietary intake survey from 481 young women. Vitamin A intake values were calculated based on the data in USDA database. Average age, height, and weight of the subjects were 20.05 years, 162.13cm and 54.38 kg, respectively. The subject's average intake of energy was 1645.67kcal. The mean vitamin A, retinol and b carotene intakes were 908.35863.18 ug retinol equivalent/day, 199.19166.00ug/day and 3872.594972.17ug/day, respectively. The 21.83% of the subjects consumed less than the Estimated Average Requirement (EAR) for vitamin A. And subjects consumed 141.69% of the Recommended Nutrient Intake (RNI) for vitamin A. Food groups consumed with high vitamin A content in our subjects included vegetables (423.96ug RE/ day), potato and starches (213.64ug RE/day), cereals (62.60ug RE/day), eggs (55.17ug RE/day) and milks (53.45ug RE/day). The major food sources of vitamin A were sweet potato, carrot, spinach, egg, and cereal, and the top 30 foods provided 89.57% of total vitamin A. Also animal-derived food provided 9.65% of the vitamin A intake from the top 30 foods. In conclusion, judging from RNI, the vitamin A intake of the Korean female university students in this study was generally adequate. The result of our study may be used as a basis for follow-up studies of vitamin A intake like assessment of vitamin A nutritional status or evaluation of carotenoid food sources in Korean young women.
