我国男性成年人血清矿物质含量正常值范围的探讨

目的探讨我国男性成年人血清矿物质含量的正常值范围。方法选择分布于我国南北地区20个调查点、接受集中供膳的健康男性成年人1109例,采用火焰原子吸收光谱法测定血清中锌(Zn)、铁(Fe)、铜(Cu)、镁(Mg)、硒(Se)等5种矿物质的浓度。结果①男性成年人血清Zn、Fe、Cu、Mg、Se含量及参考范围(mg/L)依次为:1.109(0.870,1.442),0.361~2.751;1.311(0.812,1.819),0.263~4.289;0.868(0.651,1.053),0.233~1.527;20.560(19.013,22.013),16.307~26.616;0.03814(0.01994,0.05779),0.003797~0.09346。②基于行业标准或按百分位数法不计上下限10%,筛选后的男性成年人血清Zn、Fe、Cu、Mg、Se含量及参考范围(mg/L)依次为:1.109(0.929,1.359),0.638~1.815;1.320(1.013,1.624),0.654~1.975;0.868(0.700,1.006),0.493~1.244;20.806(19.517,21.874),18.355~24.474;0.0381(0.0227,0.0524),0.0125~0.0752。结论建议我国男性成年人血清Zn、Fe、Cu、Mg、Se浓度的正常值范围(mg/L)暂定为0.64~1.82、0.65~1.98、0.49~1.24、18.36~24.47和0.013~0.075,应考虑膳食摄入量和扩大样本量进行进一步探讨。
