按照全国统一的“ＰＰＳ”方法进行碘缺乏病的抽样调查，共抽检８～１０岁儿童１２０２人，甲状腺触诊检查肿大率为２２．１％，Ｂ超检查为１３．５％；采集儿童随机尿样３４９份，尿碘中位数为１８８．２μｇ／Ｌ；其中≥１００μｇ／Ｌ的２７０份，占７７．４％；检测居民户用盐样１１２４份，其中碘盐９８６份，占８７．７％，合格碘盐８７３份，占碘盐的８８．５％，非碘盐和土盐１３８份，占１２．３％；盐碘中位数为３６．９ｍｇ／ｋｇ；采集新生儿脐带血片７１６份，合格样５９２份（８２．７％），检出＞５μＩＵ／ｍｌ的３８６份，占６５．２％。本调查资料表明，经过二年的不懈努力，无论是在碘盐食用率、尿碘水平和儿童甲状腺肿患病率，都较１９９５年有了可喜的变化；但也应看到碘盐食用率和甲状腺肿大率等指标还距国家规定的消除标准（分别为＞９５％和＜５％）差距甚远，尤其是新生儿脐带血ＴＳＨ水平更显突出，充分说明居民碘营养不足的状况依然存在，全民补碘防治工作仍不容乐观
In accordance with the national unified “PPS” method for sampling iodine deficiency disorders, a total of 1202 children aged 8 to 10 were sampled, the palpation rate of thyroid palpation was 22.1%, and the rate of B-ultrasound was 13.5%. Children were collected There were 349 random urine samples with a median urinary iodine concentration of 188.2 μg / L, of which 270 were ≥100 μg / L, accounting for 77.4%. A total of 1124 salt samples were collected from households, of which 986 were iodized salt, accounting for 87% .7%, qualified iodized salt 873, accounted for 88.5% of iodized salt, non-iodized salt and soil salt 138, accounting for 12.3%; salt iodine median 36.9mg / kg; collected neonatal umbilical cord There were 716 blood samples, 592 samples (82.7%) qualified samples, and 386 samples were detected with 5μIU / ml, accounting for 65.2%. The survey data show that after two years of unremitting efforts, both in the iodized salt consumption rate, urinary iodine levels and prevalence of goiter in children, have made gratifying changes compared with 1995; but also should see iodized salt consumption And goiter rate and other indicators are also far from the elimination of the national standards (95% and <5%, respectively) far from the gap, especially in neonatal cord blood TSH levels are more prominent, fully demonstrated the status of iodine deficiency in residents is still Existence, the national prevention and treatment of iodine still not optimistic
