目的：了解开封地区儿童锌元素含量的分布和变化规律，为防治儿童缺乏微量元素提供参考依据。方法采取随机抽样方法，抽取本地区2014年0个月~6岁健康体检儿童2054例，其中男1205例，女849例。使用原子吸收光谱仪测定锌元素含量。结果2014年男女童末梢血锌含量随年龄增长呈上升趋势(P<0.01)，同年龄组中男、女童之间锌元素含量差异无统计学意义(P>0.05)，受检儿童总的缺锌率为26.5豫，各年龄段缺锌率大致相同。结论随着人们优生优育意识的加强和对锌元素认识的深入，儿童锌元素缺乏率有所降低，但学龄前儿童缺锌率仍较高，应重视儿童膳食平衡，促进锌元素补充和吸收。

Objective To understanding the distribution and variation of children zinc level in Kaifeng to provide guid-ance for the prevention of children's lack of trace elements. Methods All 2054 cases of healthy children aged 0 month to 6 years old were randomly sampled in 2014 in the region, among which 1205 cases were male and 849 cases were female. Their Zinc levels were tested with atomic absorption spectrometry. Results Peripheral blood zinc levels of the boys and girls in 2014 was positively related to age (P<0.01), and there were no significant gender differences in the same age group (P>0.05). The overall deficiency rate was 26.5% in the sample and was similar among different age groups. Conclusion As people become more aware of the need of prenatal and postnatal care and have deeper under-standing of zinc, zinc deficiency rate in children has decreased. However, the rate is still high among preschoolers. At-tention should be paid to promote balanced diet among them to increase zinc supplement and absorption.
