目的了解广州市海珠区0~6岁体检儿童微量元素、维生素D及血铅水平。方法将2014年辖区内常驻人口中的1 093例体检儿童,根据年龄分为A组(0~12个月366例)、B组(13~36个月352例)、C组(37个月~6岁375例)。对所有入选对象进行微量元素、维生素D及血铅水平的检测,结合年龄进行检测结果的分析。结果 1 093例入选儿童钙(Ca)、铁(Fe)、锌(Zn)、镁(Mg)、铜(Cu)缺乏率、维生素D缺乏率、血铅超标率分别为29.73%、15.74%、25.71%、2.65%、4.30%、13.08%、1.19%;男、女童的微量元素缺乏率、维生素D缺乏率及血铅超标率差异均无统计学意义(P>0.05);A组Fe缺乏率高于其他两组(P<0.05);B组Zn缺乏率高于其他两组(P<0.05);C组Ca缺乏率及血铅超标率高于其他两组(P<0.05);三组Mg、Cu、维生素D缺乏率无明显差别(P>0.05)。结论 0~6岁儿童均存在不同程度的微量元素和维生素D缺乏,同时年龄稍大儿童更易发生血铅超标,应加强对家长进行相关知识的宣传,并定期进行检测,结合不同年龄段儿童生长发育特点提出相应干预措施。
Objective To understand the trace elements, vitamin D and blood lead levels in children aged 0 ~ 6 years in Haizhu District of Guangzhou City. Methods A total of 1 093 children were enrolled in the study. According to their age, they were divided into group A (366 cases in 0-12 months), group B (352 cases in 13 to 36 months), group C (37 Month to 6 years old 375 cases). All selected subjects for trace elements, vitamin D and blood lead levels, combined with age analysis of test results. Results The 1 093 children with Ca, Fe, Zn, Mg, Cu deficiency, vitamin D deficiency rate and blood lead excess rates were 29.73% and 15.74% respectively, 25.71%, 2.65%, 4.30%, 13.08% and 1.19% respectively. There was no significant difference between the male and female micronutrient deficiencies, the vitamin D deficiency rate and the blood lead excess rate (P> 0.05) (P <0.05). The Zn deficiency rate in group B was higher than that in the other two groups (P <0.05). The Ca deficiency rate and blood lead excess rate in group C were higher than those in the other two groups (P <0.05) Mg, Cu, vitamin D deficiency rate no significant difference (P> 0.05). Conclusions Children with 0-6 years old have different levels of trace elements and vitamin D deficiency. At the same time, older children are more likely to have excessive blood lead. Propagation of parents’ knowledge should be strengthened and regular testing should be carried out. Combined with the growth of children of different ages Development characteristics of the corresponding interventions.
