重庆市渝北区2011—2015年碘缺乏病监测结果分析

Analysis of monitoring results Iodine deficiency disorders in Yubei District during 2011 to 2015

目的综合分析2011—2015年重庆市渝北区碘盐、尿碘、甲状腺肿大等监测数据,为本区消除碘缺乏病提供依据。方法对全区居民按东、西、南、北、中划分5个抽样片区,随机抽检居民食用盐,采用直接滴定法定量测定含碘量。儿童甲状腺肿大采用B超法,尿碘采用砷铈催化分光光度方法测定。结果 2011—2015年全区共监测居民户盐样1 560份,非碘盐率为0.83%,碘盐合格率为92.04%,碘盐覆盖率为99.17%,合格碘盐食用率为92.05%,碘盐中位数为28.97mg/kg。儿童的尿碘中位数为280.25μg/L,甲状腺肿大率为4.95%,孕妇的尿碘中位数为266.75μg/L。结论渝北区各项碘缺乏病监测指标均位于国家控制指标以内,达到消除碘缺乏病标准。

Objective To comprehensively analyze the monitoring data of Urinary iodine and Salt iodine in Yubei District during 2011-2015,provide basic information for elimination of iodine deficiency disorders.Methods The region of residents according to the East,West,South,north,were divided into five sampling area,a random sampling of residents in edible salt by direct titration quantitative determination of iodine content.The goiter by ultrasonography,urinary iodine by arsenic cerium catalytic spectrophotometric method for the determination of.Result 1 560 salt samples were collected,during 2011-2015,non-idolized salt rate was 0.83%,iodlized salt qualification rate was 92.04%,iodlized salt coverage rate was 99.17%,iodlized salt consumption rate was 92.05%,and salt median iodine was 28.97 mg/kg.Urinary iodine median of children was 280.25μg/L,Goiter rate was 4.95%,Urinary iodine median of pregnant women was 266.75μg/L.Conclusions All the monitoring indicators were lower than the general level,satisfied the elimination standard of IDD.
