摘要: 目的 了解中国学龄前儿童血清叶酸水平、叶酸缺乏情况,并与WHO及美国疾控中心(CDC)提供的血清叶酸参考值范围进行比较,为中国学龄前儿童血清叶酸参考值的制定提供依据及意见。方法 2018年5月—2019年12月跨越中国东南西北中5个地区的13个城市招募儿童,最终获得1 373例小于7岁儿童样本,采用全自动化学发光免疫分析法(Mindray,CL-1000i,China)定量测定血清叶酸水平。结果 总体血清叶酸水平为12.46(10.08~15.35)ng/mL,参考区间(P5P95)为6.89~21.00ng/mL,将CDC血清叶酸<2ng/mL、WHO血清叶酸<4ng/mL及本研究血清叶酸P5所对应血清叶酸值6.89ng/mL分别作为血清叶酸缺乏临界值,本人群叶酸缺乏人数分别为0人、3人(0.22%)、66人(4.81%);不同年龄组间血清叶酸水平比较差异有统计学意义(F=1.244,P<0.05)。血清叶酸与年龄呈负相关(β=-0.998),与WAZ、HAZ、BMIZ无相关关系。各年龄组不同性别血清叶酸水平比较差异无统计学意义(P>0.05)。结论 单个界值点判断血清叶酸缺乏不适用于学龄前儿童,其血清叶酸参考值需要按照年龄制定。

Abstract: Objective To understand the situation of the serum folic acid level and folic acid deficiency in Chinese preschool children, and to compare them with the current reference range of serum folic acid provided by WHO and the United States US Centers for Disease Control and Prevention (CDC), so as to provide basis and suggestions for the establishment of the reference value of serum folic acid for Chinese preschool children. Methods From May 2018 to December 2019, children were recruited from 13 cities across five geographical regions in China, and finally a sample of 1 373 healthy children under 7 years old was obtained. Serum folic acid level was quantitatively determined by automatic chemiluminescence immunoassay (mindray, CL-1000i, China). Results The overall serum folic acid level was 12.46 (10.08~15.35)ng/mL, and the reference interval (P5-P95) ranged from 6.89 to 21.00ng/mL. Taking serum folic acid level <2ng/mL (CDC standard), <4ng/mL (WHO standard) and <6.89ng/mL(P5 in this study) as the threshold values for serum folic acid deficiency, the number of folic acid deficiency in this population was 0, 3 (0.22%) and 66 (4.81%), respectively. The difference in serum folic acid level between different age groups was statistically significant (F=1.244, P<0.05). Serum folic acid level was negatively correlated with age (β=-0.998), and has no significant correlation with WAZ, HAZ and BMI. There was no statistical difference in serum folic acid level between boys and girls among children in different age groups (P>0.05). Conclusion The determination of serum folic acid deficiency at a single threshold point is not applicable to preschool children, and the reference value of serum folic acid level should be set according to age.
