摘要
维生素A是人体必需的营养素之一。在世界范围内严重的维生素A缺乏已经得到有效控制的情况下,“亚临床状态”的维生素A缺乏依然是许多国家,尤其是发展中国家所面临的公共卫生问题。准确地评价高危人群的维生素A营养状况对于研究临床和亚临床维生素A缺乏对人体健康的影响以及营养干预策略的制订和实施有着极为重要的意义。目前用于评价人体维生素A水平的指标包括临床症状、组织学指标、功能指标和生化指标等。
Vitamin A is one of nutrients which are indispensable to all people, especially children and pregnant women. In the world, severe vitamin A deficiency (VAD) has been controlled efficiently. But to many countries, especially those developing, subclinical or marginal vitamin A deficiency is still a public health problem. It is very important and necessary to assess the status of vitamin A of the population who are in risk of VAD before drawing and carrying out the intervention strategy. Currently, clinical, histological, functional and biochemical methods can be used to evaluate the level of vitamin A.
