摘要
目的探讨中学生视力低下与体内微量元素含量之间的关系,为预防中学生视力低下提供依据。方法选取视力低下(实验组)和视力正常(对照组)中学生各30名,采用原子吸收分光光度法测定其枕发中锌(Zn)、铁(Fe)、铜(Cu)、钙(Ca)、镁(Mg)、镉(Cd)含量。结果与对照组相比,视力低下者发中Zn,Fe,Ca,Mg含量明显较低,差异有非常显著性(P<0.01);Cu含量虽然低于对照组,但差异无显著性(P>0.05);Cd含量明显较高,差异有非常显著性(P<0.01)。结论视力低下与体内Zn,Fe,Ca,Cu,Mg含量偏低有关。
Objective To explore the relationship between trace elements in hair and poor eyesight among middle school students, and to provide evidence for poor eyesight prevention. Methods Thirty students with poor eyesight （ test group ） and another thirty normal students （ control group ） were chosen. With method of atomic absorb spectrocolorimetry, contents of Zn, Fe, Cu, Ca, Mg and Cd were determined. Results Compared with the control group, contents of Zn, Fe, Ca and Mg were significantly less than the test group （ P〈0.01 ）, while the content of Cd was significantly higher （ P〈0.01 ）. Cu in test group was less, but no significant differences were found （ P〉0.05 ）. Conclusion Poor eyesight is correlated to less contents of Zn, Fe, Ca, Cu and Mg in body.
