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 evaluate the control effect of the policy sustainable elimination of iodine deficiency disorders on the disease status after 15 years salt iodization, and to provide a scientific basis for the relevant policy adjustments. Methods Probability sampling method (PPS) was used to select 30 counties in Jiangsu province(except those iodine excess areas), of each county 40 children aged 8 - 10 were selected as the investigation objects, their thyroids were examined by palpation and B ultrasound, urinary iodine(UI), household salt iodine, and intelligence quotient(IQ) were also investigated. A questionnaire-based health education survey of children and women was also conducted. Results A total of 1200 salt samples were detected and the coverage and qualified rates of iodized salt were 97.5%(1170/1200) and 94.5%(1134/1200), respectively. Five hundred and ninety eight urinary samples of children aged 8 to 10 were detected. The median urinary iodine was 325.3 μg/L. Of 1200 children aged 8 to 10 examined, goiter was 1.70% (20/1200) by palpation and 1.00% (12/1200) by B ultrasound. Average IQ of those 598 children was 112.4 ± 13.2, and the proportion of mental retardation was 0.5% (3/598). The health education awareness were 95.9%(1830/1908) and 96.4%(431/447) for 636 students and 149 family women, respectively. Conclusions The control effect of iodine deficiency disorders is significant in Jiangsu province. Salt iodine concentration should be adapted to people's iodine nutritional status. Iodine nutrition needs of special population such as pregnant, lactation women and infants should be taking into account, and should also be combined with salt iodization status surveillance at county level.     

2011年江苏省淮安市碘缺乏病病情调查结果分析

目的 调查2011年江苏省淮安市碘缺乏病病情现状,为适时采取针对性防治措施和科学调整干预策略提供依据.方法 2011年,按照《全国碘缺乏病防治监测方案》的要求,在淮安市采用按人口比例概率抽样方法(PPS)选取30个乡(镇),每个乡(镇)抽取1所小学,每所小学抽取8～10周岁儿童40名作为观察对象.采用触诊法检测儿童甲状腺肿大情况,采集其家中食用盐样,直接滴定法测定含碘量.从40名儿童中抽取12名采集尿样,用砷铈催化分光光度法检测尿碘.采用问卷对抽中学校5年级学生(30人)和学校所在地的家庭主妇(5名)进行碘缺乏病知识调查.结果 甲状腺触诊检查8～ 10岁儿童1200名,甲状腺肿大率为1.3％(15/1200),均为Ⅰ度肿大;各年龄组甲状腺肿大率分别为0.8％(3/390)、1.8％(7/390)和1.3％(5/420).采集8～ 10岁儿童尿样360份,尿碘中位数为171.5 μg/L,其中＜20μg/L的比例为0(0/360),＜50μg/L的比例为1.1％(4/360),＜100 μg/的比例为5.6％(20/360);检测儿童家中盐样1200份,碘盐覆盖率为99.4％(1193/1200),碘盐合格率为97.7％(1165/1193),合格碘盐食用率为97.1％(1165/1200),非碘盐率为0.6％(7/1200).调查5年级学生900人、家庭主妇150人,碘缺乏病知识知晓率分别为82.7％(2234/2700)和69.8％(314/450).结论 淮安市8～ 10岁儿童甲状腺肿大率、居民盐碘和8～ 10岁儿童尿碘均保持在消除碘缺乏病阶段目标水平,但碘缺乏病知识知晓率偏低,今后在防治碘缺乏病工作中除了加强碘盐监测,保证供应合格碘盐外,还应重点加大健康教育的宣传力度.
