济南市区学龄儿童碘营养状况调查

Investigation on the Status of Iodine Nutrition of Schoolchildren in Jinan City

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 method of PPS(probability proportional to size)was used to test thyriod en- largement rate,urinary iodine and intelligence quotient(IQ)of primary school children and detect TSH incord blood of the newborn as well as iodine content of drinking water. Out of 1 253 schoolchildren investigat-ed at age 10,thyroid enlargement rates were 5.51%by B mode ultrasonography and 14.29%by palpation. Detecting 1 171 urinary samples,median of urinary iedine was 100.17 μg/L and 49.79%were under 100 μg/L The mean IQ of 1 546 schoolchildren tested was 105.5±15.82 with 1.29% mentality fallen behind.Of the322 newborn,26.1%of TSH contents in cord blood were more than 5 mU/L,and the mean content of wateriodine was 2.583±0.439 μg/L within the range of 2.0～3. 2 μg/L. According to the standard set by WHO,UNICEF and ICCIDD,it indicates that there is mild iodine deficiency among the community in Jinan city.
