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 progress of prevention and treatment of iodine deficiency disorders in Hainan Province from 2004 to 2011 and to provide a scientific basis for the prevention and treatment of iodine deficiency disorders in the future. Methods The data of urinary iodine in goats, urinary iodine, IQ and 18-18 years old women of childbearing ages from 8 to 10 years old collected in Hainan Province from 2004 to 2011 were collected and analyzed. Results The average iodine content of domestic consumption of salt in Hainan Province was between 22.0 and 31.8 mg / kg from 2004 to 2011, and kept around 31.5 mg / kg after 2009, and the percentage of qualified iodized salt of residents increased from 66.98% to 94.79% (χ2 = 435.1, P <0.01). The median urinary iodine of children aged 8-10 years and women of reproductive age were 92.2-202.5μg / L and 71.9-170.7μg / L, respectively, increased by 110.3μg / L <0.01) and 98.8μg / L (F = 173.2, P <0.01). The rate of goiter in children was decreased by 5.74% (χ2 = 184.5, P <0.01) . Conclusion From 2004 to 2011, great achievements have been made in preventing and treating Iodine Deficiency Disorders in Hainan Province. After 2009, the indicators reached the standard of elimination of iodine deficiency disorders. Children’s iodine nutrition was at an appropriate level and their intelligence level increased year by year. Although iodine nutrition of women reached a suitable level Level, but close to the lower limit in the future still need to strengthen the publicity and monitoring of this group of people.
