摘要
目的：了解子长县重点人群的碘营养状况,掌握全县居民碘盐普及情况,以及食用碘盐后的变化情况.为今后降低地方性甲状腺肿的发病率,消除碘缺乏病提供可靠的科学依据.方法：采用人口比例概率抽样法[pps]在全县抽取9个乡镇、36个行政村、288户、288份食用盐、盐碘监测采用GB/T130.25.7-1999直接滴定法.在9个碘盐监测乡镇中,随机抽取5所小学,采用触诊法按地方性甲状腺肿大的诊断标准[WS-2007-207]检查210名8-10岁儿童的甲状腺,质量保障,组织参加人员进行组织培训和技术培训,统一技术标准.在另外5个所乡镇小学随机抽100名8-10岁儿童采集晨尿检测.结果：碘盐覆盖率100%、碘盐合格率98.61%,甲肿率3.81%,尿碘,〈100ug/l占2%,〉200ug/l占68%,中位数240ug/l,男性中位数211.45,女性中位数258ug/l.均数232.2ug/l,男均数225.2,女均数247.6,8岁中位数216.67,9岁中位数220.00,10岁中位数263.33,男女均数之间差别t=1.898〈0.05,p〉o.o5,男,女均数之间差别无统计学意义.男女中位数差别X2=4 〉3.84〉0.05 p〈0.05,所以男女中位数差别有统计学意义.结论：通过监测抽查,子长县人群总体碘营养状况良好.碘摄入量可以满足机体需要.但部分人群碘水平低,应加强健康教育的力度,使群众能长期食用合格碘盐.尿碘中位数240ug/l尿碘大于100-200ug/l标准达68%,表明碘摄入量超过量达68%.应进一步调查原因,或适当控制碘摄入量,或改变饮食结构,调节不良饮食习惯.
Objective：Analysis on iodine nutritional status of the focal population of Zichang county, check the use of iodized salt. Methods：9 towns are selected,including 36 villages by the pps （Probability Proportion to Size） methods,288 sets of edible salt. 5 towns are selected from the 9 towns where the iodized salt have been surveyed randomly. Select one primary school from each of the five town. The thyroid glands of the 210 children between 8 and 20 years old are checked. In the other 5 towns,5 primary schools are selected randomly. Urine morning of the 100 children between 8 and 10 years old are checked. Result：The used ratio of iodized salt is 100% ,the percent of pass of iodized salt is 98.61% ,its defective percent is 1.39%, the prevalence of goiter is 3.81%,〈2% of the children＇s urine iodine are lower than 100ug/1,68% are higher than 200ug/l ,the median of the results is 240ug/l,the mean is（232.2±82.44）. Conclusion：Totality,the overwhelming majority of Zichang county don＇t have iodine deficiency, a few people lack iodine,and they need more health education. People whose extra urine iodine are higher than 68% have to reduce their iodine intake and its reason should be further investigated.
