Analysis on the Iodine Nutrition Status among Populations of Shanwei City

目的分析汕尾市人群碘营养状况,评估汕尾市碘缺乏病干预措施落实情况和防治效果.方法按人口容量比例概率抽样方法(PPS)进行抽样,调查8～10岁学生尿碘水平、甲状腺肿大率、家庭食盐含碘量.结果8～10岁学生尿碘中位数为115.5μg/L,甲状腺肿大率为8.25%,家庭碘盐合格率为98.0%,合格碘盐食用率为93.6%.结论自1996年实施全民供应碘盐以来,汕尾市人群碘营养状况得到明显改善,并于2000年达到实现消除碘缺乏病的阶段目标.

[Objective] To analyze the iodine nutrition status among populations of Shanwei City and evaluate the implementation of IDD intervention work. [Methods] Proportion Probability Sampling （PPS） method was applied to investigate the urinary iodine level and the rate of goiter among children aged form 8 to 10, and the iodine content in the salt of their families was also tested. [Results] The median of the urinary iodine was 115.5Jig/L, the prevalence rate of goiter 8.25 %, the rate of the qualified iodized salt was 98.0% and the consumption rate of the qualified iodized salt was 93.6%. [ Conclusion] The iodine nutrition status among populations of Shanwei was significantly improved after salt iodination was implemented in 1996, and the stage goal for IDD elimination by the year 2000 was achieved.
