摘要
目的:调查石家庄市2—6岁儿童全血微量元素(Cu、Fe、Ca、Mg、Zn)和铅状况,以便制定合理的膳食结构,纠正儿童不良的饮食习惯和行为,保障儿童的生长、发育。方法:采用随机整群抽样的方式从8所幼儿园中抽取儿童1581名,其中男835名;女746名。按年龄分成4组。2岁一组360名;3岁一组408名;4岁一组420名;5岁~组393名。采用原子吸收分光光度仪和阳极溶出电解仪分别对儿童全血微量元素和铅进行测定。利用SPSS11.0统计软件包进行数据处理,对不同年龄、不同性别间进行F、t检验作统计分析。结果;以平均值±1倍标准差的形式来表示所有儿童全血微量和铅的测定结果如下(-↑x±5):Fe,(5.14±1.17)斗μmol/L;Ca,(1.15±0.27)mmoL/L;Zn,(107±20.9)μmol/L;Cu,(20.43±7.48)μmol/L;Mg,(1.70±0.45)mmol/L;Pb,0.357±0.13μmol/L。除Mg、Cu缺乏较少外,Ca、Zn、Fe的缺乏和铅中毒都占相当的比例,各元素间除血铅性别间差异有显著性外。其它元素性别、年龄间差别均无显著性。结论:石家庄市2—6岁儿童全血Fe、Ca、Zn缺乏和铅中毒有相当高的比率.Mg和Cu缺乏的比率较低.
Objective: To investigate the status of the whole blood trace element: ferrum (Fe), zinc (Zn), calcium (Ca), magnesium (Mg), copper (Cu) and blood lead (Pb) concerntration of children aged 2 - 6 years old in Shijiazhuang, so as to settle reasonable meal construction, rectify the bad living and behavior habits, proceed the artificial interfere, guarantee the growth of child. Methods: The whole blood trace element and blood lead were measured by method of atomic absorption spectrometry and postive anode electrolysis respectively in a population of 1 581 children aged 2 -6 years old from the eight kindergartens by random cluster sampling. The result was analyzed using SPSS11. 0 software. Results: The measurement result was as following (-↑x± s) : Fe, (5. 14 ±1. 17)μmol/L; Ca, ( 1. 15±0. 27) μmol/L; Zn, (107±20. 9) μmol/L;Cu, (20. 43±7. 48) μmol/L; Mg, (1. 70±0. 45) mmol/L; P b, (0. 357±0. 13) μmol/L. Except the less whole blood Mg and Cu lack, the Ca, Zn, Fe lack and lead poisoning rate were serious. The blood lead concentration in male was significantly higher than that in female (P 〈0. 01 ), other element didn't show sexual and ages difference respectively (P 〉0. 05) . Conclusion: The rate of whole blood Fe, Ca, Zn lack and Pb poison are higher, the rate of Mg, Cu lack are lower.
