2008年河北省碘缺乏病防治效果调查分析

Objective To investigate the current situation of the prevention and control of iodine deficiency disorders(IDD)in the Hebei province for 2008 to find problems and provide a basis for the prevention and control of IDD.Methods According to the history of IDD,2-3 counties were chosen each city of Hebei.A town with Serious IDD historically was selected in each county with 2-3 primary schools investigated subsequently.One hundred students aged 8-10 years old were chosen to examine their thyroid size and to collect urine samples for iodine content.Forty salt samples chosen from the above students and 50 urine samples of fertile women.18-40 years old,living near the above school were tested for iodine content.Water iodine was detected.Results A total of 92 water samples were collected in 23 towns.The water iodine ranged from 0.21 to 61.25μg/L.AU 2410 children had their thyroids checked by the palpation method and the goiter rate was 2.4%.1312 salt samples were collected.Iodized salt accounted for 92.4%(1212/1312),of which,96.4%(1169/1212)were qualified and the consuming rate of qualified iodized salt was 89.1%(1169/1312).30.4%(7/23)of counties consumed qualified iodized salt.accounting for 90%of the total.A total of 2191 urine samples of children and 1000 urine samples of fertile women were detected to be 185.2 μg/L and 201.3 μg/L,respectively.Conclusions The iodine nutrition of two groups in Hebei province is appropriate.However,if taken separately,two groups in Wuan Rre probably at the level of defective nutrition.We presume from the results that the possibility of iodine deficiency in pregnant and nursing women is existent in areas with low coverage rate of iodized salt.Surveillance should be strengthened in these areas and the measure of replenishing iodine should be taken for pregnant and nursing women when necessary.

2008年山东省碘缺乏病高危地区核实调查

Objective To survey the highly risk iodine deficiency regions of Shandong Province and to provide reference basis for further executing urgent iodine supply. Methods The annual document of cretinism in Licheng District in Jinan City and Shouguang City, the two iodine deficiency regions, were referred. Forty children aged 8-10 years of 2 targeted schools from 3 towns out of every targeted region underwent palpation, ultrasonography and As3+-Ce4+catalyzing speetrophotometry for ultra iodine examination. Twenty women aged 18-40 years from 2 villages sampled from every targeted town received ultra iodine examination and edible salt examination of iodine with direct titration. Results No new cretinism and suspected cretinism was found since 1995 in the regions. The goiter rates of children of the two regions detected with palpation and ultrasonography were 7.5% (18/241),6.2% (15/241) and 5.0% (13/259), 1.2% (3/259), respectively. Two hundred forty and 249 urine samples were respectively collected in school children, in which the median urinary iodine was 226.3,282.7 μg/L. One hundred twenty urine samples were respectively collected from the two group of women, resulting a median urinary iodine of 187.2,321.7 μg/L. Eight and 2 salt samples were free of iodine in 120 salt samples collected each region, respectively. The rate of qualified iodized salt was 100%. Conclusions It is not necessary to urgently implement iodine supply in Shouguang City and Licheng District. However, reinforcement of supervise on salt industry and eliminating the hazard from non-iodized and disqualified iodized salt remains in need.

One primary school was selected in each village(office), fifty students aged 8 - 10 in each primary school were randomly selected to check thyroid and their urine and edible salt were collected to detect iodine. Thirty 5th-grade students in each school were selected to carry out the questionnaire survey of health education about iodine deficiency disorders. According to the east, west, south, north and center position, five potable water samples were selected to detect iodine in the village where the primary school was in. Questionnaire survey was also carried out among ten housewives in the village. Thyroid was examined by palpation;ammonium persulfate digestion-arsenic cerium catalytic spectrophotometry(WS/T 107-2006) was used to detect urinary iodine;direct titration(GB/T 13025-1999 ) was used to detect salt iodine;arsenic cerium catalytic spectrophotometry (GB/T 5750.5-2006) was used to detect water iodine. Results One thousand and five hundreds children aged 8 - 10 were analyzed in 6 counties(cities, districts), the rate of goiter was 3.30%(50/1500), the median of urinary iodine was 273.15 μg/L. One thousand and five hundreds salt samples were detected, the coverage rate of iodized salt was 99.93% (1499/1500), the qualified rate of iodized salt was 98.00% (1469/1499), the edible rate of qualified iodized salt was 97.93% (1469/1500), the coverage rate of non-iodized salt was 0.07% (1/1500), the median of salt iodine was 28.9 mg/kg. One hundred and fifty water samples were collected, the median of water iodine was 2.76 μg/L. The pass rate of the questionnaire survey of health education about iodine deficiency disorders was 97.11% (874/900) in students and 98.67% (296/300) in housewives, respectively. Conclusions The prevention and control of iodine deficiency disorders has achieved significant results and the monitoring indicators have reached the national standard for eliminating iodine deficiency disorders in Sanmenxia city.     

2011年福建省碘缺乏病病情监测结果分析

目的 分析福建省碘缺乏病病情监测结果,掌握福建省消除碘缺乏病进程和食用盐碘浓度调整前人群碘营养水平.方法 2011年采用按人口比例概率抽样法在全省抽取30个县(市、区),每个县(市、区)抽取1所小学,每所小学抽取40名8～ 10岁儿童,B超法检测甲状腺容积,直接滴定法测定儿童家庭食用盐碘.采集其中12名儿童尿样,砷铈催化分光光度法检测尿碘,并用三日称量法调查其家中居民日人均食盐摄入量.在抽中学校的所在村(居委会),按东、西、南、北、中各抽取1份饮用水水样,如为集中式供水地区,则采集2份末梢水样,砷铈催化分光光度法测定水碘.在抽中学校附近,选择3个乡(镇、街道办事处),每个乡(镇、街道办事处)抽取孕妇和哺乳妇女各5人,采集尿样,砷铈催化分光光度法检测尿碘.结果 共检查1219名8～ 10岁儿童甲状腺,甲状腺肿大率为4.92％(60/1219);检测363份尿样,尿碘中位数为223.00μg/L,其中＜50 μg/L的占5.2％(19/363),＜100 μg/L的占14.6％(53/363);452名孕妇尿碘中位数为147.2 μg/L,其中＜150 μg/L的占52.0％(235/452);461名哺乳期妇女尿碘中位数为134.1 μg/L;1211份居民户合格碘盐食用率为94.4％(1143/1211);360户居民入均日食盐摄入量为6 g,81.4％(293/360)的居民入均日食盐摄入量在9 g以下;76份居民饮用水含碘量中位数为6.2 μg/L,＜10 μg/L的占89.5％(68/76).结论 2011年福建省各项指标继续达到“消除碘缺乏病标准”,但存在孕妇碘缺乏问题,对存在碘缺乏的孕妇应给予额外的碘补充.
