【摘要】 目的调查河北省2007年居民户碘盐覆盖率≤80%的7个市(县)、区碘缺乏病流行情况。方法按照《全国碘缺乏病监测方案》确定的碘缺乏病高危地区调查范围,甲状腺触诊和B超法检查按照卫生部颁发的《地方性甲状腺肿诊断标准》(W S276-2007),尿碘浓度检测采用砷铈分光光度测定方法(W S/T107-2006),盐碘含量采用直接滴定法测定。结论7市(县)、区均未构成碘缺乏病高危地区,但仍有3个县加权法儿童甲状腺肿大率超过5%,4个县居民户碘盐覆盖率<80%,部分县尿碘中位数在正常范围偏低水平,需进一步提高居民户碘盐覆盖率。更多还原

【Abstract】 Objectives To investigate the prevailence of IDD in 7 counties with coverage of iodized salt below 80% in Hebei Province in 2007.Methods The confirmation of high risk areas of IDD is in line with National Surveillance Plan for IDD.Thyroid palpation and B type ultrasonic measurement were conducted according to the Diagnostic Criteria of Endemic Goiter issued by Ministry of Health.The iodine content in urine was tested by arsenic-cerium catalyze spectrophotometry and the salt iodine was tested by direct titration method.Conclusions 7 counties under survey were not up to the standard of high risk areas of IDD.Nevertheless,the weighted goiter rates of schoolchildren were over 5% in 4 counties;the coverage of iodized salt at household level were less than 80% in 5 counties;the urinary iodine median of some counties were at the lower end of the normal range,so the coverage of iodized salt at household level need to be enhanced in these counties.更多还原
