海南省2004～2011年碘缺乏病监测结果分析

Results of monitoring of iodine deficiency disorders(IDD) in Hainan from 2004 to 2011

目的了解2004～2011年海南省碘缺乏病防治进展情况,为今后碘缺乏病防治工作提供科学依据。方法收集海南省2004～2011年监测的居民户食用盐、8～10岁儿童甲状腺肿、尿碘、智商及18～40岁育龄妇女尿碘的数据进行汇总分析。结果 2004～2011年海南省居民户食用盐平均碘含量在22.0～31.8 mg/kg之间,2009年后保持在31.5mg/kg左右,居民合格碘盐食用率由66.98%上升到94.79%(χ2=435.1,P<0.01);8～10岁儿童和育龄妇女尿碘中位数分别在92.2～202.5μg/L和71.9～170.7μg/L,分别提高了110.3μg/L(F=175.1,P<0.01)和98.8μg/L(F=173.2,P<0.01);儿童甲状腺肿大率在0.1%～5.9%,下降了5.74%(χ2=184.5,P<0.01);儿童智商在89～95。结论 2004～2011年,海南省碘缺乏病防治工作取得了很大成绩,2009年后各项指标达到碘缺乏病消除标准,儿童碘营养处于适宜水平,智力水平逐年提高;妇女碘营养虽达到适宜水平,但接近下限,今后仍需加强这组人群的宣传和监测。

Objective To understand the status of iodine deficiency disorders（IDD） in Hainan from 2004 to 2011 and provide scientific basic for the future prevention of deficiency disorders.Methods Surveillance data on resident iodized salt content,goiter of pupils aged 8-10,urinary iodine,IQ and 18-40 years old women urinary iodine of Hainan province from 2004 to 2011 were collected and analyzed.Results From 2004 to 2011,the average iodine content in salt was ranged 22-31.8 mg / kg,it remained at around 31.5mg / kg since 2009,the rate of qualified iodized salt in household increased from 66.98% to 94.79%（χ2= 435.1,P 0.01）;The median value of urine iodine in 8-10 years old children and women was 92.2-202.5 g / L and 71.9-170.7 g / L,respectively improved 110.3u g / L（F = 175.1,P 0.01） and 98.8 u g / L（F = 173.2,P 0.01）;The goiter rate of children was 0.1-5.9%,reducing by 5.74%（χ2= 184.5,P 0.01）;IQ was 89-95.Conclusion From 2004 to 2011,iodine deficiency disease prevention in Hainan has made great achievements,Each index has achieved the national standardization of IDD elimination goal since 2009.The iodine nutrition of the children was suitable,and the level of intelligence quotient was improved among the years;The iodine nutrition of women reach suitable,but closed to the lower limit,so iodine nutrition surveillance and health education in women should be strengthened.
