2010年东方市碘缺乏病监测分析

Results of monitoring of iodine deficiency disorder in Dongfang City in 2010

目的了解东方市居民碘盐普及情况及碘缺乏病病情现况。方法在东方市3个碘盐覆盖率较低的乡镇开展8～10岁儿童碘缺乏病病情监测、育龄妇女尿碘监测,在全市开展居民碘盐食用情况监测。结果检测8～10岁儿童240人,触诊法检测甲状腺肿大率为3.75%,B超法检测甲状腺肿大率为0.00%;儿童尿碘中位数为134.4μg/L,育龄妇女尿碘中位数为157.8μg/,儿童智商分值96.6±14.5;碘盐覆盖率95.83%,较2007年提高了56.25个百分点,合格碘盐食用率95.14%,较2007年提高了58.33个百分点。结论东方市近几年来居民碘盐普及率的不断提高,儿童和育龄妇女碘营养水平均得到有效改善,儿童甲状腺肿下降到正常范围,下一步应继续保持和巩固普及碘盐消除碘缺乏病的政策措施。
