【摘要】 目的了解广东沿海及珠江三角洲地区人群碘营养状况。方法用人口比例概率抽样法对该地区抽取３０个调查点１２９３名８～１０岁在学儿童进行甲状腺肿大率、尿碘、盐碘调查；同时调查了儿童的智商水平和新生儿脐带血ＴＳＨ。结果Ｂ超法检查甲状腺肿大率１２．４５％，触诊法检查甲状腺肿大率１２．２２％；盐碘覆盖率５６．２％；尿碘中位数１２４．６０μｇ／Ｌ；平均智商为１０３．４，处于边缘状态和智力落后的儿童占６．８５％；ＴＳＨ＞５ｍＵ／Ｌ的占１０．２５％。结论广东沿海及珠江三角洲地区同样存在碘摄入不足的公共卫生问题，但多属轻度缺碘更多还原

【Abstract】 Objective In order to review nutrition status of iodine in Guangdong coastal areas and the Pearl river delta.Methods After 30 experimental spots were selected in Guangdong coastal areas and the Pearl river delta by population proportional probability sampling method,1293 school aged children (age 8￣10y) were conducted thyroid monitoring,urinary iodine and iodined salt measurement.1430 children’s mental development data were collected.439 neonate umbilical cord blood samples were used to inspect TSH level.Results Goiter rate was 12.45%/12.22% among children by respective ultrasonography/palpation method.56.2% children were administered iodined satl.The median concetration urinary iodine was 124.60μg/L.Average IQ was 103.4 6.85% children showed relarded mental development.10.25% blood samples bad TSH level larger than 5mU/L.Conclusions We concluded that less obvious iodine deficiency was still a public health problem along Guangdong coastal areas and the Pearl river delta.更多还原
