应用温和酸消化法对上海市区１４２７名五年级学生进行了尿碘测定。结果显示，尿碘中位数为７１．２７μｇ／Ｌ，尿碘值＞１００μｇ／Ｌ者所占比例为３１．８９％。男女学生的尿碘中位数分别为７８．４１μｇ／Ｌ和６３．８７ｇ／Ｌ，有非常显著的差异（μ＝４．８８，Ｐ＜０．００１）。１０个市区学龄儿童尿碘中位数范围为６０．８９～１００．１５μｇ／Ｌ；按ＷＨＯ／ＵＮＩＣＥＦ／ＩＣＣＩＤＤ的判别标准评估本市有９／１０的区为轻度缺碘地区。此外，午后收集尿样的碘浓度（７９．０５μｇ／Ｌ）显著高于上午收集的尿样（６５．８５μｇ／Ｌ），且前者尿碘频数分布向高值偏移。
Urine iodine was measured in 1427 fifth grade students in Shanghai using mild acid digestion. The results showed that the median urinary iodine 71.27μg / L, urinary iodine value> 100μg / L accounted for 31.89%. The urinary iodine median of male and female students were 78.41μg / L and 63.87g / L, respectively. There was a significant difference (μ = 4.88, P <0.001). The median urinary iodine of 10 urban school-age children ranged from 60.89 to 100.15 μg / L. According to the WHO / UNICEF / ICCIDD criteria, 9/10 of the districts were mildly iodine-deficient. In addition, the concentration of iodine in urine collected in the afternoon (79.05 μg / L) was significantly higher than that collected in the morning (65.85 μg / L), and the distribution of urinary iodine frequency shifted to a higher value.
