摘　　要：为了解城市学龄前儿童末梢血锌元素的含量,探讨我国学龄前儿童微量元素锌缺乏的综合防治措施,采用BH 5100 T型原子吸收光谱仪对沈阳、长乐、兰州及成都市的3～6儿童末梢血中的锌的含量进行了测定,采用SPSS 17.0软件进行了统计分析。结果表明,沈阳、长乐两市学龄前儿童末梢血Zn含量低于正常值,兰州、成都两市处于正常范围;四城市学龄前儿童末梢血Zn含量缺乏严重,缺乏比例依次为沈阳66.90%、长乐61.92%、兰州59.73%、成都47.06%;不同城市相同性别的学龄前儿童末梢血Zn含量比较差异有统计学意义(P<0.05)。提示四个城市的学龄前儿童末梢血Zn缺乏严重,不同城市的学龄前儿童末梢血Zn含量差异明显,应针对不同地区的膳食特点,加强微量元素Zn补充,确保儿童的健康生长。To analyse the difference in peripheral blood zinc levels in children aged 3 -6 years between four cities, the content of zinc in peripheral blood of children aged 3 - 6 years in Shenyang, Changle, Lanzhou, Chengdu was detected by atomic absorption spectrometry. The data were analysed with SPSS 17.0 software. The results showed that zinc content in peripheral blood of children in Shenyang and Changle were lower than reference value. Serious zinc deficiency were common among these four cities. Deficiency rate of zinc was 66.90% in Shenyang, 61.92% in Changle, 59.73% in Lanzhou and 47.06 in Chengdu. There were significant difference among the content of zinc levels in peripheral blood with same ender four cities （P 〈0.05）. It concluded the unbalance of zinc levels was existed among these four cities. According the regional food, the zinc supplementary should be strengthened in order to keep nutritional balance and children＇s healthy.
