【摘要】 目的 :通过对武汉市某区 180 0名 3岁以下婴幼儿发样分析 ,探讨该区婴幼儿发中铜、锌、铁、钙、镁含量的正常水平和婴幼儿部分微量元素营养状况。方法 :采集婴幼儿发样进行预处理后用火焰原子光谱法测定其铜、锌、铁、钙、镁含量 ,并对测定结果进行卫生统计学处理。结果 :发铜在性别间有显著性差异 (P <0 .0 5 ) ,年龄间差异无显著性 (P >0 0 5 ) ;发锌、钙、镁、铁性别间差异不显著 (P >0 .0 5 ) ,0~ 3月组与其它组别差异显著(P <0 0 5 ) ,0~ 3月婴儿发中铜、锌、铁、钙、镁含量均处于一个较高水平。锌、铜随着年龄的增长至 3~ 12月其含量均呈下降趋势 ,随着年龄进一步增长至 12~ 2 4月 ,其含量略呈回升趋势。铁、钙、镁的含量随年龄的增加呈下降趋势 ,但均处于正常水平 ,且钙与镁呈伴随趋势。结论 :婴幼儿应加强微量元素的营养补充。

【Abstract】 Objective:The purpose of study was to seek the norm al levels of copper, zinc, iron, calcium and magnesium in the hair from a certain community in Wuhan by the analysis of 1800 hair samples of children in the age 0 ~3year. Method:Flame atomic absorption spectrometer was used to measure the el e ments in pretreated samples and statistical analysis of data was also applied. R esults:The difference in the copper level was significant by gender (P <0.05) but not in age groups (P>0.05).With regard to sample concentrations of zinc, calcium, magnesium and i ron, the differences were not significant by gender. However the levels of the e lements in 0~3 month-age groups were remarkably higher than those in other grou ps. The copper, zinc, calcium, magnesium and iron in 0~3 month-old children w ere at higher levels. The concentrations of copper and zinc gradually decreased as age increasing to between 3 and 12 months, however they slightly increased ag ain with age between 12 and 24 months. The levels of iron, calcium and magnesium showed gradually decreasing tendency but still in the normal range. Magnesium a nd calcium changed concomitantly. Conclusion:The trace element supplement for children should be emphasized.
