Effect of Iodine Deficiency Disease Prevention and Treatment in Jiaojiang Area in 1995～2001

目的 观察加碘食盐防治碘缺乏病 (IDD)效果。 方法 全民食用加碘食盐 (碘含量 3 5± 15 )mg/kg。观察评价指标 :8～ 10岁儿童甲状腺肿大率、尿碘水平、碘盐合格率和新生儿TSH。 结果 碘盐防治前 1995年甲肿率11 73 % ,尿碘中位数 10 9 3 5ug/L。防治后 2 0 0 1年甲肿率 6 2 8% ,前后比较具有统计学意义 (χ2 =14 45 0 ,P <0 0 1) ,尿碘中位数 2 5 3 41ug/L ,前后比较亦具有统计学意义 (u =6 943 1,P <0 0 1) ,加工厂、销售点和居民用户碘盐合格率分别为94 3 3 %、97%和 90 93 % ,TSH >5mu L比率 0 11%。 结论 加碘食盐防治IDD方法简便、经济、效果显著 。

Objective To explore the effect of iodine deficiency disease(IDD) prevention and treatment using iodized salt. Methods All people demanded to consume in their diet iodized salt(containing iodine 35±15) mg/kg. Evaluation index:goiter rate and urine iodine level of the children aged 8～10, acceptance rate of iodized salt, and neonatal thyroid stimulating hormone(TSH). Result 11.73% of goiter rate and 109.35 ug/K of urine iodine median in 1995 before iodized salt taken, where as the figures were 6.28%(χ 2=14.450,P<0.01) and 253.41 ug/L(U=6.9431,P<0 01) in 2001 after iodized salt consumed. Acceptance rates of iodized salt are 94.33% in processors, 97% in distributors and 90.93% in residential users. TSH>5 mU/L, ratio 0.11%. Conclusion Iodized salt method for IDD prevention and treatment is both convenient and economical and shows obvious effect. Staged target has been realized in eliminating IDD in the said area.
