本文采用概率抽样法（ＰＰＳ法），对济南市区３０所小学的儿童甲状腺肿大率，尿碘和智力进行了测验，检查了新生儿脐带血ＴＳＨ水平和饮水碘含量。调查１０岁学生１２５３名，甲肿率Ｂ超法为５．５１％，触诊法为１４．２９％；查尿１１７１份，尿碘中位数为１００．１７μｇ／Ｌ，尿碘值在１００μｇ／Ｌ以下者占４９．７９％；测验１５４６名学生智商，平均智商为１０５．５±１５．８２，智力落后者占１．２９％；３２２份新生儿脐带血ＴＳＨ含量＞５ｍＵ／Ｌ者占２６．１％；水碘含量均值为２．５８３±０．４３９μｇ／Ｌ，其泛围在２．０～３．２μｇ／Ｌ之间，根据ＷＨＯ、ＵＮＩＣＥＦ及ＩＣＣＩＤＤ联合推出消除碘缺乏病标准，说明济南市区人群存在着轻度碘缺乏，应采取以供应碘盐为主的综合性补碘措施。
In this paper, the probabilistic sampling method (PPS method) was used to test the thyroid enlargement rate, urinary iodine and intelligence of children in 30 elementary schools in Jinan city. The levels of TSH and iodine in drinking water were examined. A total of 1253 students aged 10 years were enrolled in this study. The gestational disease rate was 5.51% by B-ultrasonography and 14.29% by palpation. The urinary iodine median was 100.17μg / L and urine iodine value was 100μg / L or less accounted for 49.79%; 1546 students test IQ, the average IQ of 105.5 ± 15.82, 1.29% of those with mental retardation; 322 newborns with cord blood TSH> 5mU / L accounted for 26.1%. The mean value of iodine in water was 2.583 ± 0.439μg / L, and the range was 2.0 ~ 3.2μg / L. According to WHO, UNICEF and ICCIDD, Jinan City, indicating that there is a mild iodine deficiency in population, should be taken to supply iodized salt-based comprehensive compensation for iodine.
