浙江省0～6岁儿童血清维生素A水平调查

Investigate the Serum Vitamin A Levels of Children Aged 0~6 Years in Zhejiang Proviece.

［目的］了解浙江省 ０～６岁儿童血清维生素 Ａ水平。［方法］对 １３个县的 １８４２名儿童采用微量荧光光度法检测血清维生素Ａ含量。结果血清维生素Ａ均值为（１．６２２ ３±０．９１５ ９）μｍｏｌ／Ｌ，＜０．７μｍｏｌ／Ｌ占７．８％，０．７μｍｏｌ／Ｌ～１．３９μｍｏｌ／Ｌ占３０．８９％。男女儿童无显著性差异（Ｐ＞０．０５），３岁以内幼儿血清维生素Ａ水平较低。结论维生素Ａ缺乏症发病较普遍，一般无临床表现。３岁以下的婴儿是防治该病的重点人群。要消除维生素Ａ缺乏症尚需时日。

Objective] To investigate the serum vitamin A levels of children aged 0 - 6 years in Zhejiang province. [Methods] The serum vitamin A levels of 1 842 children from thirteen counties were estimated with microfluorescence. [Results] The mean level of serum vitamin A was 1. 622 3 0. 915 9 umol/L. There were 7. 87 % children whose serum vitamin A levee were less than 0. 7umol/L and 30. 89 % children's serum vitamin A levels were 0. 7- 1. 39umol/L. There was no significance between girls' and boys' vitamin A levels. The serum vitamin A levels of children under three years (u3y) were lower. [Conclusion] The vitamin A deficiency disease was ubiquitous,but there was usually no clinical symptoms. The children u3y were the important subjects being treated and protected from this disease. It would take a long time to eliminate the vitamin A deficiency.
