银川市重点人群碘营养状况调查分析

目的监测银川市重点人群尿碘含量水平,从而估计常住居民的碘营养状况方法采用分层随机的抽样方法,银川在所辖的各县区市按东、西、南、北、中5个抽样片区进行抽样,每个县区共抽取9个乡镇,每个乡随机抽取4个行政村,共采集新婚妇女、孕妇、哺乳期妇女尿样885份。0-2岁婴幼儿尿样共386份,8-10岁儿童尿样600份。结果银川市8-10岁儿童尿碘中位数为239.10μg/L,不同地区之间尿碘中位数差别有统计学意义,（P〈0.05）;0-2岁的婴幼儿尿碘中位数为201.40μg/L,不同地区之间尿碘中位数差别无统计学意义,（P〉0.05）;特殊妇女人群尿碘中位数为216.0μg/L,不同地区之间尿碘中位数差别无统计学意义,（P〉0.05）。结论银川市碘营养水平已经超过国家推荐的适宜范围,敏感个体有碘致甲亢的可能,所以应因地制宜地调整盐碘和供应方式,实现因地制宜、分类指导和科学补碘的方针。
