目的:了解平南县各年龄段及不同性别儿童的血浆锌水平,为合理防治儿童锌缺乏提供参考。方法:2007年12月～2011年8月进行健康体检的2 643名儿童,按年龄分为婴儿期、幼儿期、学龄前期、学龄期4个组,采集空腹静脉血置于肝素抗凝管中,使用北京普析通用仪器有限责任公司生产的血液微量元素分析仪检测血浆中微量元素锌含量。对不同年龄段及不同性别儿童血浆锌水平进行比较。结果:平南县受检男性儿童血浆锌平均(72.20±32.20)μmol/L,女性儿童血浆锌平均(77.66±40.00)μmol/L;受检儿童锌缺乏检出率为40.37%,其中男性儿童血浆锌缺乏率为40.53%,女性儿童血浆锌缺乏率为40.20%,男女儿童之间血浆锌缺乏率无统计学差异(P>0.05);年龄越大,血浆锌缺乏发生率越低,血浆锌缺乏高峰为婴儿期。结论:平南县儿童锌缺乏比较严重,年龄越小,血浆锌缺乏发生率越高,建议定期检测微量元素锌,及时发现,早期治疗,以减少锌缺乏相关疾病的发生。
Objective: To understand the level of plasma zinc in children of all ages and gender in Pingnan County and to provide reference for the prevention and treatment of zinc deficiency in children. Methods: A total of 2 643 children undergoing physical examination from December 2007 to August 2011 were divided into four groups according to their ages: infancy, early childhood, preschool age and school age. Fasting venous blood was collected in heparin anticoagulation tubes , The use of Beijing General Instrument Co., Ltd. Purification of blood produced by trace elemental analyzer for detecting trace elements in plasma zinc content. Plasma zinc levels in children of different ages and genders were compared. Results: The plasma zinc level in Pingnan County was (72.20 ± 32.20) μmol / L and that in female children was 77.66 ± 40.00 μmol / L. The detection rate of zinc deficiency in children was 40.37% Plasma zinc deficiency rate was 40.53%, female children plasma zinc deficiency rate was 40.20%, plasma zinc deficiency rate between boys and girls was no significant difference (P> 0.05); older age, the lower the incidence of plasma zinc deficiency, plasma zinc Lack of peak for infancy. Conclusion: Children with zinc deficiency are more serious in Pingnan County. The younger the age, the higher the incidence of zinc deficiency. It is suggested that the trace element zinc should be detected periodically to detect and treat early to reduce the incidence of zinc deficiency related diseases.
