A cross-reference survey on th iodine nutritive status of the urban school-age children in Hangzhou

对杭州市区环境碘和１０２５８人次８～１０岁儿童补碘前后及防治二年后碘营养状况进行对比调查分析。结果显示：饮水碘为１．４８μｇ／Ｌ，膳食碘共计６０．５μｇ／ｄ，盐碘０．５２ｍｇ／ｋｇ，防治前儿童触诊甲肿率１０．０２％，Ｂ超甲肿率１４．９８％，尿碘中位数７０．０１μｇ／Ｌ，大于１００μｇ／Ｌ仅占３０．２０％，儿童平均智商为１１２．１４，其中郊区儿童为１０４．４５。经过落实以食盐加碘为主的综合防治措施二年后，儿童甲肿率下降至５．１６％。尿碘中位数上升到２４３．１５μｇ／Ｌ，儿童平均智商为１１４．３７。表明防治前杭州市区外环境和人群机体内环境同样存在碘缺乏，碘干预措施是我市防治碘缺乏病的积极有效方法。
