摘要
目的了解深圳市8～10岁学龄儿童碘营养状况,评价碘缺乏病防治效果。方法于1999、2002、2009和2011年对全市10个区学龄儿童按照概率法进行随机抽样,检测尿碘、智力水平(IQ值)和甲状腺肿大率。结果 1999—2011年深圳市8～10岁学龄儿童尿碘中位数分别为230.1、229.3、232.2和207.1μg/L,均符合《碘缺乏病消除标准》;IQ值分别为100.88、103.28、107.74和108.26,平均值为105.04,4年间IQ值分布的构成比差异无统计学意义(χ2=11.084,P>0.05);甲状腺肿大率分别为8.3%,4.4%,2.1%和1.3%,呈逐年降低趋势(χ2=43.323,P<0.05),达到《碘缺乏病消除标准》的要求。结论本次调查的深圳市8～10岁学龄儿童碘营养状况良好,仍需继续施行食盐加碘,以巩固碘缺乏病的防治效果。
Objectlve To understand the iodine-nutritional status of school children aged 8-10 years and to assess the effect of iodine deficiency disorders （IDD） prevention and control in Shenzhen. Methods A probabilistic method and random sampling were used to test the urinary iodine, intelligence level and the goiter rate in pupils selected in 10 districts of Shenzhen from 1999 to 2011. Results The median of urinary iodine for the school children aged 8 to 10 years were 230.1, 229.3, 232.2 and 207.1μg/L respectively, which accord with Standard for Elimination of IDD; The intelligence level were 100.88, 103.28, 107.74 and 108.26 respectively, the average level was 105.04, the constituent ratio of the IQ distribution was not significant（xZ=ll.084, P〉0.05）. Goiter rate was reduced by 8.3%, 4.4%, 2.1% and 1.3% which were within a rational range of IDD elimination standard （χ2=43.323, P〈0.05）. Conclusion The status of iodine-nutrition of school children aged 8 to 10 years in Shenzhen is in good condition. However, the policy of universal salt iodization should be still needed to strengthen IDD prevention.
