摘　　要：目的研究高碘地区居民停止食用碘盐对甲状腺肿的影响。方法随机抽取2个高碘乡8～10岁儿童用B超法诊断地方性甲状腺肿,同时检测居民的食用碘盐情况。结果停供碘盐前儿童甲状腺肿大率为10.57%,停供碘盐后1年时儿童甲状腺肿大率为5.36%,差异有统计学意义(χ2=4.84,P<0.05)。停供碘盐前与停供碘盐后1年时,碘盐覆盖率差异有统计学意义(χ2=104.53,P<0.01)。结论该县属水源性高碘地区,居民应食用无碘盐。[Objective]To study the effect of the discontinuation of iodized salt on the incidence of goiter among residents in excessive iodine regions.[Methods]Children aged 8-10 years old were randomly selected from 2 excessive iodine townships,the endemic goiter was diagnosed by B-ultrasound,and the consumption status of iodized salt among residents was detected.[Results]The incidence rate of goiter among children before the discontinuation of iodized salt was 10.57%,that at one year after the discontinuation was 5.36%,and the difference was statistically significant（χ2=4.84,P0.05）.There was significant difference in coverage rate of iodized salt between before the discontinuation of iodized salt and one year after the discontinuation（χ2=104.53,P0.01）.[Conclusion]Cheng＇an County is the aquagenic excessive iodine region,and residents should use the non-iodized salt.
