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 analyze monitoring results of iodized salt and distribution characteristics of problem areas with non-iodized salt in Gansu province during 2001 - 2009 and to provide a basis to develop countermeasures to iodine deficiency disorders. Methods According to the criterion of "The National Scheme of Iodized Salt Surveillance", two levels of monitoring were carried out on production and wholesale-level(during 2001 -2007) and household-level(during 2001 - 2009). Salt iodine was determined by direct titration method (GB/T13025.7-1999), and Sichuan salt or special salt was determined with an arbitration method. Criteria for qualified iodized salt was (35 ± 15)mg/kg(20 - 50 mg/kg), and for non-iodized salt was ＜ 5 mg/kg. Results During 2001 - 2007, a total of 4900 salt samples at production and wholesale-levels were examined, with a qualification rate of 97.80% (4792/4900). Non-iodized salt rates were all below 5% in Gansu province, consumption rate of qualified iodized salt was higher than 90% after 2003. During 2001 - 2009, cities(states) with non-iodized salt problems appeared 23 times, with Linxia accounting for 39.1%(9/23), Wuwei accounting for 21.7%(5/23). During 2001 -2009, counties(districts) with non-iodized salt problem appeared 123 times, including 68 times of ethnic minorities and state poverty counties, accounting for 55.3%(68/123). During 2001 - 2005 and 2006 - 2009, ethnic minorities and state poverty counties were accounting for 49.4%(44/89) and 70.6%(24/34) in counties with non-iodized salt problem. Conclusions The quality of iodized-salt at production and wholesale level is satisfactory in Gansu province, household consumption rate of qualified iodized salt have reached national standard for eliminating iodine deficiency disorders. But ethnic minorities and state poverty counties are main regions with non-iodized salt problem,these areas will be the key areas of prevention of iodine deficiency disorders in Gansu province in the future.

目的 评估四川省雅安市实现消除碘缺乏病目标情况,掌握全市碘缺乏病防治现状.方法 2009年,按照<四川省实现消除碘缺乏病目标县级考核评估方案>开展县级考评.以县为单位,对8个县(区)的防治资料进行综合评分,并统计分析居民户碘盐监测数据;按东、西、南、北、中5个方位各抽取1个乡(镇),每个乡(镇)各抽取1所小学,每所学校抽取80名8～10岁儿童,触诊法(WS 276-2007)检查甲状腺;收集其中20名8～10岁儿童尿样,砷铈催化分光光度法(WS/T 107-2006)检测含碘量:同时抽取30名5年级学生和该校附近10名家庭主妇,进行碘缺乏病知识问卷调查.结果 8个县(区)资料评分平均为89.96分,范围为85.42～92.90分;居民户碘盐覆盖率为100.00%(2328/2328),碘盐合格率为97.98%(2281/2328),合格碘盐食用率为97.98%(2281/2328);8～10岁儿童甲状腺肿大率为0.91%(33/3620);800名8～10岁儿童尿碘中位数为235.85μg/L,且<50μg/L的占1.50%(12/800);5年级学生和家庭主妇碘缺乏病防治知识问卷调查及格率分别为92.33%(1131/1225)、94.3%(397/421).结论 雅安市以县为单位全部实现消除碘缺乏病目标,但碘缺乏病与碘营养过剩趋势并存,今后应注意每日碘盐食用量的问题,需科学补碘才能持续消除碘缺乏病.

Abstract：

Objective To evaluate the investigation outcome of eliminating iodine deficiency disorders(IDD)in Ya'an city of Sichuan province,and to master the current situation of IDD in the whole city.Methods In 2009,according to"Counties'Assessment Guideline in Sichuan for Implementing the Measure to Eliminate Iodine Deficiency Disorders",assessments were conducted.At county level,composite score was given to collected data of the eight counties(districts)and monitoring data of household iodized salt were statistically analyzed.A township (town)was randomly selected by east,west,south,north and center locations,respectively.One primary school was randomly selected in each selected township(town),eighty children aged 8 to 10 in each selected school were checked of their thyroid by palpation(WS 276-2007)and urinary iodine level of20 children among them was measured by As3+_Ce4+ catalytic spectrophotometry(WS/T 107-2006).Thirty fifth-grade students and 10 housewives lived around school were asked to take a questionnaire survey.Results Average score of the 8 counties(districts)was 89.96,ranged from 85.42 to 92.90.The coverage rate of iodized salt of household was 100.00%(2328/2328),rate of qualified iodized salt was 97.98%(2281/2328).and consumption rate of qualified iodized salt reached 97.98%(2281/2328).The goiter rate of children aged 8-10 was 0.91%(33/3620),median urinary iodine was 235.85μg/L,and 1.50%(12/800)of child's urinary iodine was less than 50μg/L.The rate of passing a knowledge questionnaire survey of the fifth-grade students and women was 92.33%(1 131/1225)and 9413%(397/421),respectively.Conclusions Ya'an city in Sichuan province has reached the goal of eliminating iodine deficiency.disorders,but there is a coexist trend of IDD and iodine excess.They should pay attention to the daily consumption of iodized salt in the future;sustained elimination of IDD can be reached only by iodine supplementation scientifically.
