为了调查日本年轻女性的维生素状况，通过 150 名 21-22 岁女学生的 3 天称重食物记录来评估维生素 A、E、C、B1、B2、B6、B12、烟酸、叶酸和 β-胡萝卜素的膳食摄入量。通过 HPLC 测定维生素 B1、B2 和烟酸的全血水平，以及视黄醇、α-生育酚、维生素 B6 和 β-胡萝卜素的血清水平。血清维生素B12、叶酸采用化学发光免疫分析法测定，血清维生素C采用二硝基苯肼法测定。当应用第六次修订的日本每日推荐摄入量（体力活动水平 1）时，46.7% 的女性显示维生素 A 摄入量充足，E 摄入量为 28.7%，B1 摄入量为 80.7%，B2 摄入量为 92.7%，B6 摄入量为 54.7%，烟酸摄入量为 99.3%，B12 摄入量为 76.0%，叶酸摄入量为 34.0%， C 为 54.0%。总维生素 A (microgRE) 摄入量的 59% 来自 β-胡萝卜素。能量摄入的平均值+/-标准差较低，为1.572+/-315 kcal。发现能量摄入量和所有这些维生素之间存在显着相关性。相应维生素摄入量高于 RDA 的女性的血清叶酸和抗坏血酸水平显着高于摄入量低于 RDA 的女性。血液维生素水平与维生素 B12 (r=0.185)、叶酸 (r=0.255)、维生素 C (r=0.272) 和 β-胡萝卜素 (r=0.319) 的维生素摄入量之间存在显着相关性。叶酸、抗坏血酸、维生素 B2、B12 和 β-胡萝卜素的平均血液水平在摄入量最高的四分位数中高于最低四分位数。从摄入足够维生素的女性获得的血液维生素水平的 95% 置信区间几乎与从所有受试者获得的结果相同。只有少数女性（0.7-4.7%）的血液维生素水平低于下限。血清α-生育酚水平与血清视黄醇、β-胡萝卜素和维生素C水平显着相关。该数据表明，年轻女性应增加适当的膳食摄入量，以保持良好的维生素状态。此外，应进行足够的体力活动以防止能量摄入过多。
To investigate the vitamin status of young Japanese women, dietary intakes of vitamin A, E, C, B1, B2, B6, B12, niacin, folate, and beta-carotene were assessed by a 3-d weighed food record in 150 female students aged 21-22. Whole blood levels of vitamin B1, B2, and nicotinic acid, and serum levels of retinol, alpha-tocopherol, vitamin B6, and beta-carotene were determined by HPLC. Vitamin B12 and folate in serum were measured by chemiluminescence immunoassay, and serum vitamin C was done by dinitrophenylhydrazine method. When the 6th revision RDAs for the Japanese (physical activity level 1) were applied, 46.7% of the females showed sufficient intake for vitamin A, 28.7% for E, 80.7%, for B1, 92.7% for B2, 54.7% for B6, 99.3% for niacin, 76.0% for B12, 34.0% for folate, and 54.0% for C. Fifty-nine percent of total vitamin A (microgRE) intakes were derived from beta-carotene. The mean+/- SD of energy intakes was low, 1.572+/-315 kcal. Significant correlations among intakes of energy and all these vitamins were found. Serum folate and ascorbic acid levels in the females with corresponding vitamin intakes above the RDA were significantly higher than in those with intakes below the RDA. There were significant correlations between blood vitamin levels and vitamin intakes in vitamin B12 (r=0.185), folate (r=0.255), vitamin C (r=0.272), and beta-carotene (r=0.319). Mean blood levels of folate, ascorbic acid, vitamin B2, B12, and beta-carotene were higher in the highest quartile of intake than in the lowest. The 95% confidence intervals of blood vitamin levels obtained from the females with sufficient vitamin intakes were nearly equal to those obtained from all subjects. Only a few females (0.7-4.7%) had their blood vitamin levels below the lower limits. Serum alpha-tocopherol levels were significantly correlated with serum levels of retinol, beta-carotene, and vitamin C. This data suggested that young women should increase suitable dietary food intakes in order to maintain good status of vitamin. Moreover, sufficient amount of physical activity would be expected for prevention of excessive energy intake.
