摘　　要：目的通过对学龄儿童的尿碘和盐碘水平进行调查,对上海市黄浦区学龄儿童的碘营养状况进行评价。方法采用随机抽样方式在黄浦区10所学校选取8~10岁的儿童450人,对研究对象进行问卷、碘盐水平及尿碘浓度检测。结果调查结果显示,尿碘中位数为199.00μg/L。尿碘适宜、缺乏、超过适宜的比例分别为32.67%、17.56%和49.78%,盐碘均值为17.33±11.56 mg/kg,碘盐覆盖率为71.56%。不同性别和年龄的尿碘水平比较,差异有统计学意义(P<0.05)。是否食用碘盐对尿碘水平的影响,差异有统计学意义(P<0.05)。结论黄浦区学龄儿童的碘营养适宜,但也存在一定比例的碘缺乏和碘过量情况。应进一步下调盐碘浓度,使一般人群的碘营养水平更加趋向于适宜状态,并加强碘营养重点人群的健康教育。Objective To evaluate the iodine nutritional status of school-age children in Huangpu District of Shanghai by investigating the levels of urine iodine and salt iodine in school-age children.Methods A total of 450 children aged 8-10years were selected from 10 schools in Huangpu District by random sampling.The subjects were tested with questionnaires,salt iodine level and urine iodine concentration.Results The results showed that the median urinary iodine was 199.00μg/L.The proportion of urine iodine suitable,deficient and over suitable was 32.67%,17.56%and 49.78%respectively.The average salt iodine was 17.33±11.56 mg/kg,the coverage rate of iodized salt was 71.56%.There was statistically significant difference in urine iodine levels between different sexes and ages(P<0.05).There was statistically significant difference in the effect of iodized salt consumption on urinary iodine level(P<0.05).Conclusion The iodine nutrition of school-age children in Huangpu District is suitable,but there is also a certain proportion of iodine deficiency and iodine excess.The salt iodine concentration should be further reduced to make the iodine nutrition level of the general population more suitable and strengthen health education for key groups of iodine nutrition.
