目的 汇总分析 1999年全国碘缺乏病的监测资料 (不含港、澳、台地区 )。方法 按人口容量比例概率抽样方法 (PPS)进行抽样 ,采用国家统一的标准方法进行各项指标的检测 ,并采取相应的的质量保障措施。结果 全国 31个省份的合格碘盐食用率为 80 .6 % ,8～ 10岁儿童尿碘中位数为 30 6 .0μg/ L ,触诊法甲状腺肿大率为 8.8% ;盐碘与尿碘 2项指标之间 ,呈现较好的相关性 ,单纯食用 15～ 2 0 mg/ kg加碘盐浓度的 8～ 10岁儿童尿碘中位数为 2 0 9.8μg/ L;全国居民户盐碘中位数为 42 .3mg/ kg,>40 mg/ kg的省份有 2 4个。结论 我国在 2 0 0 0年能够达到基本实现消除碘缺乏病的阶段目标 ;目前居民户加碘盐水平存在着盐碘浓度偏高的问题 ,应该下调加碘盐浓度 ,居民户加盐碘水平以 15～ 2 0 m g/ kg为宜 ;单纯食用合格加碘盐也能满足人群的碘营养需要。
Objective To summarize and analyze the monitoring data of 1999 national iodine deficiency disorders (excluding Hong Kong, Macao and Taiwan regions). Methods Samples were taken by PPS (Population Probability Probability Sampling Method), the national standard method was adopted to test the indexes, and the corresponding quality assurance measures were taken. Results The prevalence of qualified iodized salt in 31 provinces was 80.6%, the urinary iodine median was 30 6 .0 μg / L in children aged 8-10, and the thyroid goiter rate was 8.8% in palpation. Salt iodine and urine Iodine two indicators, showed a good correlation between the simple consumption of 15 ~ 20mg / kg iodized salt concentration of children aged 8 to 10 urinary iodine median 2 0 9.8μg / L; national household salt The median iodine was 42.3 mg / kg, while 24 provinces> 40 mg / kg. Conclusion China can basically achieve the phase goal of eliminating iodine deficiency disorders by the year 2000. At present, there is a problem that the iodized salt concentration is high in households with iodized salt, and the concentration of iodized salt should be lowered and the level of salt and iodine should be lowered 15 ~ 20 mg / kg is appropriate; simple consumption of qualified iodized salt can meet the needs of the population of iodine nutrition.
