福建省龙岩市碘缺乏病病情监测结果分析

Objective To understand the current situation of iodine deficiency diserders(IDD) in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey(PPS) from the 7 counties of Longyan City. Forty children aged 8-10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rote, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8-10 years old in Longyan City was 0.94%(79/8438). The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% (1462/1494). The iodine salt coverage rate was 99.46%(1486/1494). The rate of qualified iodized salt was 98.38 (1462/1486), and the non-iodized rate was 0.54% (8/1494). Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.

Abstract：

Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -＜ 200 μg/L accounted for 24.00%(168/700), 200 - ＜ 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.

Abstract：

Objective To study the national surveillance results and learn the current situation of iodized salt consumption at household level in 2008, and to find out the remaining problems and to provide scientific basis for developing control strategies against iedine deficiency disorders. Methods In 2008, in accordance with the requirements of the "National Iodine Deficiency Disorders Surveillance Program (Trial)", the surveillance was conducted at county level in 31 provinces and at division level in Xinjiang Production and Construction Corps. In each county 9 townships were randomly selected according to their sub-area positions of east, west, south, north and center;4 villages were randomly sampled in each chosen township;8 households were randomly selected in each chosen village. In every county with 9 or less townships, 1 township was randomly selected respectively in the east, west, south,north and center sub-areas;4 villages were randomly sampled in each chosen township;15 households were randomly selected in each chosen village. Edible salt from these households was collected. Iodized salt coverage rate, proportion of qualified iodized salt and consumption rate of the qualified iodized salt of the households in each province were counted and analyzed. Iodized salt was determined by direct titration;the salt samples from Sichuan and other enhanced salt were detected by arbitration. Results Totally 2817 counties (districts, cities, banners) and 14 divisions of the Xinjiang Production and Construction Corps reported the monitoring results, monitoring coverage reached 99.96%(2831/2832). Mean of iodine content was 31.51 mg/kg.Sixteen provinces had a variation coefficient of iodine content for more than 20%. A total of 826 968 households were tested of their edible salt, in which iodized salt 798 725 copies, non-iodized salt 28 243 copies, and unqualified iodized salt 20 270 copies. Weighted by population,at national level, the coverage rate of iodized salt was 97.48%, qualified rate of iodized salt 97.16%, and consumption rate of qualified iodized salt was 94.79%.Twenty seven provinces (autonomous regions and municipalities) and Xinjiang Production and Construction Corps had a qualified iodized salt coverage rate of above or equal 90.00%. Tibet, Hainan, Xinjiang and Tianjin provinces (regions) had a qualified iodized salt coverage rate lower than 90.00%. Further, 2487 counties had the rate high or equal 90.00% accounting for 87.82% (2487/2831) of complementing monitoring counties. One hundred and four counties and 1 division of the Xinjiang Production and Construction Corps had the coverage rate of iodized salt below 80.00%. Conclusions Sixteen provinces(autonomous regions and municipalities) have relatively a high degree of variation coefficient in salt iodine content. The quality of iodized salt needs to be improved. The coverage rate of iodized salt and the qualified iodized salt at national level are both above or equal 90.00%. However, the non-iodized salt problem is still serious and have a relatively lower coverage of iodized salt in Tibet, Hainan and Xinjiang.

目的 评估全国基本实现消除碘缺乏病阶段目标后的居民户层次盐碘水平。方法 从31个省(区、市)按一定比例随机抽取一定数量的盐样进行检测，根据各省上报的盐碘定量测定结果，利用EPI INFO6．0软件进行资料汇总分析。结果 全国有26个省的加碘盐覆盖率在90％以上，有16个省的合格碘盐食用率在90％以上。结论 适当降低加碘浓度，提高加碘盐合格率，杜绝非碘盐冲击，加强碘盐监测工作，确保居民食用合格碘盐，科学地防治碘缺乏病。     

2009年河南省信阳市居民层次碘盐监测结果

目的了解信阳市居民食用碘盐情况,及时发现问题并采取相应的干预措施。方法根据《河南省碘盐监测方案》,碘盐生产、批发企业每月按东、西、南、北、中5个方位抽取一批9份盐样检测含碘量;居民户碘盐监测,在每县（区）按东、西、南、北、中划分5个方位抽取9个乡（镇、街道办事处）,每个乡（镇、街道办事处）抽取4个行政村（居委会）,每个村（居委会）抽取8份盐样,每县（区）共采集288份盐样检测含碘量。结果居民层次非碘盐率0.21%,碘盐覆盖率99.79%,碘盐合格率97.18%,合格碘盐食用率96.98%。结论从碘盐质量指标上看,信阳市已提前完成了全市消除碘缺乏病目标;一些遍远地区还存在一定的非碘盐冲击和不合格碘盐食用情况,有向市区转移的趋势。     

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。
