天津市17105名儿童叶酸营养状况调查

Investigation on folic acid condition among 17 105 children of Tianjin

[目的]了解天津市1-7岁儿童叶酸营养状况,动员全社会关注儿童叶酸营养,提高健康水平。 [方法]采用整群抽样的方法,在全市18个区县共抽取17 105名1-7岁儿童（男9 170例,女7 935例）,测定其身高、体重、血红蛋白、血浆叶酸含量等,对结果进行统计分析。 [结果]17 105名儿童血浆叶酸含量：血浆叶酸含量平均为（7.84±2.5）μg/L,叶酸低于正常的发生率为12.5%,血浆叶酸含量随年龄增长而降低,各年龄组儿童叶酸低于正常的发生率随年龄增长而升高,年龄组间及男女性别间比较差异有显著性;不同地域间比较差异亦有显著性,其中五县组叶酸低于正常发生率最高,血浆叶酸含量最低。 [结论]天津市儿童叶酸营养状况较差,叶酸低于正常高发区多集中于郊县经济不发达地区,今后应采取相应措施改善儿童叶酸营养状况。

[Objective] To understand the folic acid condition among the 1～7 years children of Tianjin,and to raise the children health condition. [Methods] 17 105 children（9 170 boys and 7 935 girls,aged 1～7 years） were selected by stratified cluster sampling in 18 districts of Tianjin.Their height,weight,hemoglobin and folic acid concentration of plasma were measured. [Results] The folic acid concentration of plasma was（7.84±2.5）μg/L.The prevalence rates of folic acid deficiency was 12.5%.There were trend toward decreased of folic acid concentration of plasma ＆ trend toward increased of the prevalence rates of folic acid deficiency as the age increased in boys ＆ girls.There was significant differences in age and sex.The folic acid concentration of plasma was lower and the prevalence rates of folic acid deficiency was higher in city group than in outsidecity group in corresponding age ＆ gender group. [Conclusions] The folic acid condition among the 1～7 years children of Tianjin is not satisfactory.It is very important to make the children folic acid condition better.
