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.

Abstract：

Objective To monitor the quality changes of iodized salt and analyze its impact factor in Chongqing between 2001 and 2009. Methods Salt samples were collected according to the east, west, south,north and center locations in iodized salt production, wholesale and household sectors. Two units in iodized salt production and wholesale segment were sampled from north, south, east and west places and only 1 unit was sampled from the central place. Nine samples were collected every month in each place. If the place had less than 9 units, and then taken all the units. About resident household, 2 townships were sampled from north, south, east and west places, and 1 township was sampled from the central place, then 20 samples were collected from each township. Iodine content was detected by oxidation-reduction assay. The index of mean iodine, qualified rate from factories and wholesale, coverage rate and taking rate of qualified iodized salt in residents were calculated.Significance was analyzed by trend test, analysis of variance and X2 test. Results The qualified rate of iodized salt from the manufacturers was 92.9%(13/14) in 2001 and the rate was 100.0% each year from 2002 to 2009. The qualified rates of iodized salt from the wholesale were 88.7%(282/318) - 99.8%(431/432). The rates of 2001 and 2002 were lower than that of other years(X2 = 4.98 - 45.69, all P< 0.05 or < 0.01). The coverage rate and taking rate of qualified iodized salt in residents were 94.2% (11 154/11 841 ) - 98.9% ( 14 061/14 217), 83.5% (9 887/11 841 ) -95.8% (13 449/14 039), respectively. The rates showed an increasing tendency (F = 9.27, 26.39, all P < 0.05).The districts(counties) with qualified iodized salt consumption rate > 90% kept increasing. The mean iodine from the manufacturers and wholesale were 29.71 - 36.25, and 31.26 - 36.13 mg/kg, respectively. The iodine level showed a descending trend(F = 35.45, 140.59, all P < 0.01 ). The mean iodine level from the inhabitants were 28.84 - 30.98 mg/kg which remained stable (F = 3.05, P > 0.05 ). The iodine level from manufacturers, wholesale to inhabitants showed an descending trend(F = 38.46 - 671.23, all P < 0.01 ). Conclusions The surveillance results of iodized salt shows an increasing tendency in quality of iodized salt, eoverage rate and taking rate of qualified iodized salt. Factors that affect the quality of iodized salt is that the enterprise does not add iodine to salt strictly by the standard.

Objective To investigate the nutritional status of iodine among residents in Chongqing, and to facilitate scientific prevention and control of iodine deficiency disorders. Methods Select 9 towns in each of the 40 districts (counties) in Chongqing, and collect 40 resident edible salt samples in each of the selected town to detect salt iodine by direct titrimetry. Select 5 towns on the site of the east, west, south, north and middle of every district (county), select 20 children aged 8 to 10 in each of the selected town to collect urine samples and detect urinary iodine by As-Ce catalytic spectrophotometric assay. Results The median of iodine of 14 217 salt specimens by household was 292 mg/kg with a coverage rate of qualified iodized salt of 98.90%( 14 061/14 217). The consumption rate of qualified iodized salt was 95.59%( 13 590/14 217). The median of urinary iodine for 4050 children aged 8 to 10 was 247.20μg/L, of which < 50 μg/L accounted for 4.60%(186/4050), 50-99μg/L accounted for 7.28% (295/4050), 100 - 199 μg/L accounted for 26.44% (1071/4050), 200 - 299 μg/L accounted for 25.58% (1036/4050), 300 μg/L or more, accounted for 36.10% (1462/4050). However, no significant difference was observed between different age groups(x2 = 3.77, P > 0.05). At district (county) level, the median of urinary iodine in 10(25.00%) districts (counties) was 100 - 200 μg/L, that in other 23(57.50%) districts (counties) was 200 - 300 μg/L, and that in other 7(17.50%) districts/counties was greater than 300 μg/L, and statistical significance was observed between different districts/counties (x2 = 441.95, P < 0.01). Conclusions Current iodine nutrition among residents in Chongqing is adequate. While there is excess, need to reduce the amount of salt iodization.

Abstract：

Objective To learn the iodine nutritional status of the vulnerable population with different iodine level under the current level of iodized salt in Shandong province and to offer prevention and cure measures.Methods Five groups of vulnerable population including school children aged 8 - 10, pregnant, lactation women, infants and women of childbearing age from mountain areas ( Daiyue, Mengyin counties ) , plain ( Luxian,Gaomi counties ) and coastal (Zhaoyuan county ) of five different iodine deficient areas were investigated in 2007.The thyroids of children aged 8 - 10 were checked by palpation and B ultrasound, their edible salt iodine level was detected by direct titration. The lever of urinary iodine of vulnerable population was examined by arsenic and cerium speetrophotometry. Results The goiter rates of 8 - 10 year-old were 1.8%(9/514) and 1.2%(6/514), respectively by palpation and B-ultrasonic. The mean iodine of 501 edible salt samples was 30.95 mg/kg. The coverage rate of iodized salt was 94.6% (474/501). The rate of qualified iodized salt was 90.4% (453/501). The median of urinary iodine was 216.7 μg,/L. The urinary iodine of school children aged 8 - 10, pregnant, lactation women, infants and women of childbearing age were 234.0, 165.5, 162.4, 257.5, 233.0 μg/L, respectively. Conclusions Current iodine nutritional level is basically appropriate in all groups of vulnerable people. The current iodine content of iodized salt could meet the needs of population from different iodine deficient areas of Shandong province.     

2008年河北省居民户碘盐供应存在的问题及原因分析

目的 找出2008年河北省居民户碘盐供应问题地区的分布特征及原因,并提出相应的改进建议。方法以县为单位,按东、南、西、北、中5个方位选取9个乡（镇）,每个乡（镇）选取4个村,每个村随机采集8户居民户盐样;采用直接滴定法检测盐碘含量。结果全省供应碘盐的167个县（市、区）中,19个碘盐覆盖率〈90％,占总数的11．38％,主要分布于我省东部的沿海产盐区和中南部平原地区,大部分为原适碘地区,占84．2％（16／19）;12个县（市、区）碘盐合格率〈90％,占总数的7．19％,主要分布在我省中南部内陆平原地区,大部分位于原适碘地区,占75％（9／12）;合格碘盐食用率〈90％的县（市、区）数为30个,占总数的17．96％,主要分布在我省中南部平原和东部沿海产盐区,24个位于原适碘地区,占80％（24／30）,6个位于原病区,占20％（6／30）;合格碘盐食用率〈90％的主要原因为碘盐覆盖率较低的县（市、区）有13个,占43．33％（13／30）,主要原因为碘盐合格率较低的县（市、区）有9个,占30％（9／30）。结论全省仍有30个县（区、市）合格碘盐食用率未达标,碘盐覆盖率较低是导致未达标的主要原因,碘盐合格率低是次要原因。
