【摘要】：目的分析中国居民主要膳食维生素的摄入状况。方法本文数据来自2010~2012年中国居民营养与健康状况监测中连续3 d 24 h膳食回顾调查。采用多阶段分层与人口成比例的整群随机抽样方法进行抽样,研究对象为中国内地31个省份150个监测点18岁及以上居民,调查总人数为64038人。不同人群平均维生素摄入量及摄入充足率采用2009年国家统计局公布的人口数据,经过复杂抽样加权处理。结果中国居民膳食来源的维生素摄入量为:视黄醇当量441.9μg,视黄醇活性当量为291.5μg;维生素E为35.7 mg,其中α维生素E为8.5 mg;硫胺素为0.9 mg;核黄素为0.8 mg;烟酸为14.3 mg,烟酸当量为21.0 mg;抗坏血酸为80.1 mg;叶酸摄入量为180.9μg。我国居民总体膳食维生素充足率为32%,烟酸的充足率最高为79.3%,叶酸的充足率最低仅为9.0%。结论中国居民膳食维生素摄入不足问题普遍存在,至少有2/3的人群存在膳食维生素摄入不足。应通过营养教育、营养强化等干预措施以提高膳食维生素的摄入水平。
[Abstract]:Objective to analyze the intake of main dietary vitamins in Chinese residents. Methods from 2010 to 2012, the data were collected from a retrospective survey of diet for 3 days and 24 hours in the monitoring of the nutritional and health status of Chinese residents. The multi-stage stratified and population-proportional cluster random sampling method was used to sample 150 residents aged 18 years and above in 31 provinces of mainland China. The total number of people surveyed was 64038. The average vitamin intake and intake adequacy rate of different population groups were weighted by complex sampling using the population data released by the National Bureau of Statistics in 2009. Results the vitamin intake from dietary sources of Chinese residents was 441.9 渭 g of retinol equivalent, 291.5 渭 g of retinol activity equivalent, 35.7 mg of vitamin E, 8.5 mg of 伪 vitamin E, 0.9 mg of thiamine, 0.8 mg of riboflavin, 14.3 mg of nicotinic acid and 14.3 mg of nicotinic acid. The equivalent was 21.0 mg, ascorbic acid was 80.1 mg, folic acid intake was 180.9 渭 g. The total dietary vitamin adequacy rate of Chinese residents is 32, the highest of nicotinic acid is 79.3 and the lowest of folic acid is 9.0. Conclusion the problem of inadequate dietary vitamin intake is common in Chinese residents, and at least 2 / 3 of the population is deficient in dietary vitamin intake. Nutritional education, nutritional fortification and other intervention measures should be adopted to improve dietary vitamin intake level.
