Abstract：

Objective To master the status in control of iodine deficiency disorders (IDD) in Gansu province and to provide the basis for development of control strategies. Methods One county which reached the national standardization of IDD elimination was selected randomly from each of 14 cities of Gansu province in 2009, then one town was selected respectively from five directions (east, south, west, north, and central) of the above selected counties. One village was chosen from every town which was selected for investigating household iodized salt and iodized salt sales network. At the same time the thyroid of children was examined, their urinary iodine (UI) was determined, the intelligence quotient(IQ) values of children were measured and health education was surveyed in one primary school which was chosen in each of the selected town. Results A total of 1420 edible salt samples were tested;the weighted iodized salt coverage rate and the weighted qualified iodized salt rate were 99.53% and 98.15 respectively. Urine samples were collected from 1761 children included in the study. The urinary iodine median was 225.87 μg/L. The urinary iodine medians were at optimal levels in five counties, over the optimal levels in seven counties and at excessive levels in two counties. A total of 3051 children aged 8 - 10 were randomly selected for thyroid examination. The weighted thyroid goiter rate(TGR) of children was 1.9%, and TGR was higher than 5% only in Hoaggu county. IQ of 2815 children was tested and the mean IQ was 105.3, except for the country of Zhuoni and Kangle, the mean IQ of other counties were over 100. The average score of health education was 3.2.Children of 57.08% (1229/2153) knew that iodine deficiency could lead to mental retardation, 71.76% (1544/2153) knew that iodine deficiency could cause thyroid goiter, 68.04%( 1465/2153 ) knew that eating iodized salt was the best method for IDD prevention and control and 61.82%(1331/2153) informed their families of the benefits of eating iodized salt. Each town had one agency selling iodized salt and each village had one more retail store with iodized salt, but 73.5%(75/102) of the stores without license for the sales. Conclusions Great progress has been made on the prevention and control of IDD in Gansu province. The qualified iodized salt consumption rate has reached the national standard for IDD elimination, TGR has decreased markedly, the urinary iodine levels in more counties are over the optimal levels and iodized salt distribution network is basically sound. But progress in health education is uneven.

2008年浙江省舟山市海岛地区甲状腺疾病流行病学调查

目的 调查浙江省舟山市海岛地区食用非加碘盐的居民患甲状腺疾病状况及致甲状腺疾病的相关影响因素.方法 2008年在浙江省舟山市岱山县对737名食用非加碘盐的居民进行流行病学问卷调查、甲状腺B超检查、甲状腺功能及尿碘测定;同时抽查了183名8～10岁儿童(均为食用非加碘盐居民的子女)的尿碘.结果 舟山市岱山县食用非加碘盐的居民尿碘中位数(MUI)为122.2 μg/L,8～10岁儿童MUI为123.7μg/L;甲状腺肿、甲状腺癌、甲状腺功能亢进(简称甲亢)、亚临床甲状腺功能亢进(简称亚临床甲亢)和亚临床甲状腺功能减退(简称亚临床甲减)的患病率分别为39.9%、0.4%、0.4%、0.7%和0.8%.logistic回归分析显示,甲状腺肿患病率无性别差异(P>0.05),而年龄是甲状腺肿发生的危险因素(P<0.05);甲状腺肿、甲亢患病情况与饮食史、吸烟史、饮酒史、饮茶史、尿碘水平均无明显相关关系(P均>0.05).结论 舟山市海岛地区食用非碘盐居民碘摄入适量,但甲状腺肿和甲亢患病率较高.     

中国部分沿海地区居民碘营养状况调查结果分析

目的 了解我国沿海地区食用碘盐防治碘缺乏病是否导致居民碘摄入过量.方法 采用横断面调查方法,在我国11个沿海省份(自治区、直辖市)中,沿着海岸线从北往南选择辽宁省、上海市、浙江省及福建省4个省(市)进行调查.除上海市调查其所有辖区外,其他的3个省都分城市和农村两个层次,分别调查了5个沿海城市、5个沿海农村,以及3个内陆农村(作为对照点)的外环境水碘、居民合格碘盐食用率、居民人均盐日摄入量以及不同人群的尿碘水平.结果 在4个省(市)共采集居民饮用水水样7552份、居民户盐样7996份和不同人群(成人、哺乳妇女、孕妇和儿童)尿样9873份.除浙江省沿海城市和沿海农村合格碘盐食用率低于90％外,其他3个沿海省(市)调查地区的合格碘盐食用率均大于90％.4个省(市)成人和儿童尿碘中位数均在100～299 μg/L;哺乳妇女尿碘中位数均大于100 μg/L;上海市、浙江省沿海城市和福建省沿海农村孕妇尿碘中位数低于150μg/L.结论 沿海地区居民的碘营养状况总体水平上是适宜的,部分沿海地区孕妇碘营养不足;沿海地区应坚持食盐加碘防治碘缺乏病的措施.     

甘肃省临夏州8～10岁儿童碘缺乏病防治效果评价

目的评价临夏州8～10岁儿童碘缺乏病防治效果。方法干预前后,分别于2006年、2010年在每个县按东、南、西、北、中抽取5个乡,每个乡抽取1个村,每个村8～10岁儿童80名(2010年40名),进行甲状腺触诊和B超检查,2010年还抽取其中20名学生采集尿样进行尿碘检测,同时每个村随机采集20户盐样进行检测。结果临夏州合格碘盐食用率从83.2%(1056/1269)升高到94.6%(756/799),8～10岁儿童甲肿率从10.3%(364/3518)下降到4.2%(72/1722),8～10岁儿童尿碘中位数为209.76ug/L,<50 ug/L比例占6.73%。结论临夏州实施碘缺乏病综合防治措施后,效果明显,儿童尿碘处于适宜水平,合格碘盐食用率、8～10岁儿童甲肿率均达到国家碘缺乏病消除标准;但部分县防治形势仍然严峻。
