浙江3市儿童血清中脂溶性维生素水平比较

目的:比较浙江3市儿童血清中脂溶性维生素水平。方法:以高效液相色谱法测定血清中脂溶性维生素浓度。结果:274份血样维生素E、维生素A和β-胡萝卜素含量分别为(9．02±2．36)、(0．53±0．10)、(0．23±0．16)μg·mL-1;25-羟基维生素D3和维生素D3检出率分别为75．55％、51．10％,检出浓度分别为(18．51±7．64)、(20．83±10．67)ng·mL-1。5种脂溶性维生素水平没有性别差异(P>0．05),但地区间差异明显(P<0．01或P<0．05)。结论:浙江3市儿童血清中维生素E、维生素A和β-胡萝卜素营养状况比较理想,但25-羟基维生素D3与维生素D3偏低较为普遍。

Investigation of Serum Level of Fat - soluble Vitamins Among Urban Children in Zhejiang Province

OBJECTIVE: To investigate and compare the serum level of fat - soluble vitamins among urban children in Zhejiang Province.METHODS: The serum level of fat-soluble vitamins was determined by RP - HPLC.RESULTS: Totally, 274 children were examined, and the average serum concentrations of vitamin E, vitamin A, and beta-carotene were(9.02±2.36), (0.53±0.10) and (0.23±0.16)μg·mL-1, respectively .The detectable rate and mean of 25- hydroxyvitamin D3 were 75.55% and (18.51±7.64) ng·ml-1, rescpectively,and 51.10% and (20.83±10.67) ng·mL-1 with vitamin D3. The serum level of fat-soluble vitamins was not significantly different between sexes(P> 0.05), but significantly different between the cities(P<0.01 or P<0.05) .CONCLUSION: The serum level of vitamin E,vitamin A, and beta - carotene among urban children from the three cities of Zhejiang Province is good as a whole,but 25- hydroxyvitamin D3 and vitamin D3 is relatively poor.
