目的为全面了解吉林省碘缺乏病病情变化趋势,掌握重点人群碘营养水平,为吉林省碘缺乏病防治工作提供科学依据,并对已采取的防治措施效果进行评价。方法采取人口比例概率抽样方法在吉林省随机抽取30个抽样单位所在的县(市、区),从上述方法抽到的每个县(市、区)中选取1所小学;在被抽到的小学中随机抽取50名8-10岁学生,用B超法检测其甲状腺大小,留尿并采集其家中食用盐,测定尿及盐中碘含量;同时,选择1个乡(镇、街道办事处),每个乡(镇、街道办事处)抽取孕妇20名检测尿碘。结果 8-10儿童B超检测甲肿率为1.41%,尿碘值中位数为157.70μg/L;居民户碘盐合格率85.13%,合格碘盐食用率70.74%;孕妇尿碘值中位数为146.50μg/L。结论通过食盐加碘为主的防治碘缺乏病综合措施的落实,我省碘缺乏病病情得到有效控制,经过2012年碘盐浓度调整,8-10岁儿童甲状腺肿大率及尿碘值均达到国家消除碘缺乏病标准。说明居民碘营养水平是适宜的,但也应注意孕妇等特需人群碘营养水平有待提高以及可能存在非碘盐冲击市场影响消除碘缺乏病的因素存在。
Objective To comprehensively understand the changing trend of iodine deficiency disorders in Jilin Province and to master the iodine nutrition of key populations so as to provide a scientific basis for the prevention and control of iodine deficiency disorders in Jilin Province and to evaluate the effect of prevention and control measures taken. Methods A population proportion sampling method was used to randomly select counties (cities and districts) where 30 sampling units were located in Jilin Province. One primary school was selected from each county (city and district) Fifty pupils aged 8-10 years were randomly selected from primary school, thyroid size was measured by B-ultrasonography, urine was collected from their families, and the iodine content in urine and urine was measured. Meanwhile, one township (town and sub-district offices ), Each township (town, sub-district office) to take 20 pregnant women to detect urinary iodine. Results The prevalence of B-ultrasonography in children with B-ultrasound was 1.41% and the median urinary iodine was 157.70μg / L in 8-10 children. The qualified rate of iodized salt in residents was 85.13% and the qualified rate of iodized salt was 70.74% The number is 146.50 μg / L. Conclusion The implementation of comprehensive measures to prevent iodine deficiency disorders by salt iodization is effective in controlling iodine deficiency disorders in our province. After adjustment of iodized salt concentration in 2012, the rates of goiter and urinary iodine in children aged 8-10 reached Countries to eliminate iodine deficiency disorders standards. It shows that iodine nutrition level of residents is suitable, but it should also pay attention to the need of pregnant women and other special needs of the population to improve the level of iodine nutrition and the possible existence of non-iodized salt impact on the market to eliminate iodine deficiency disorders.
