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 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.

贵州省黔南自治州都匀县石龙乡和平圹县四寨乡、清水乡系地方性甲状腺肿重病区。对三个重病乡居民经用同一产地、同一浓度(1/5万)碘盐防治,十三年后调查结果:石龙、四寨二乡学生甲状腺肿大率降到国家控制地甲病的标准,二乡学生智商水平比加碘前都有显著提高。但清水乡学生甲状腺肿大率居高(47.9％)不下,且在加碘二年或四年学生智商水平都没有显著提高,但清水乡成人尿碘均值均达到国家基本控制地甲病的标准。我们认为清水乡地甲病除缺碘因素外,还应考虑其他致病因素的存在。
