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 ,该地区已实现消除IDD阶段目标
Objective To observe iodized salt prevention and treatment of iodine deficiency disorders (IDD) effect. Methods All people eat iodized salt (iodine content 35 ± 15) mg / kg. Observations and evaluation indicators: goiter rate, urinary iodine level, iodized salt pass rate and neonatal TSH in children aged 8 to 10 years. Results Before iodized salt prevention in 1995, the rate of goiter was 11 73% and the median urinary iodine was 10 9 3 5 ug / L. After the prevention and treatment of 201 cases of goiter rate 62.8%, before and after comparison was statistically significant (χ2 = 14450, P <0 01), urinary iodine median 2 5 3 41ug / L, before and after comparison With a statistical significance (u = 6 943 1, P <0.01). The passing rates of iodized salt at processing plants, point-of-sale and residential users were 94.33%, 97.0% and 90.93%, respectively. 11%. Conclusion Iodized salt prevention and treatment of IDD method is simple, economical and effective, the region has achieved the goal of eliminating IDD phase
