摘　　要：采用ＰＰＳ法抽样，对３０个县（市）儿童进行碘营养调查，以了解广西儿童碘营养的现状。结果表明，环境水含碘中位数为２．４μｇ／Ｌ，整个广西境内均属于缺碘地区，尚未发现高碘的局部地区。１２００份学生家用碘盐含碘中位数４１．３ｍｇ／ｋｇ，合格率为９０．０８％。其中精盐含碘中位数４２．３ｍｇ／ｋｇ，合格率为９１．２７％，粗盐含碘中位数３８．１ｍｇ／ｋｇ，合格率为８５．５４％，精盐含碘合格率高于粗盐（Ｐ＜０．０１）。３６０份尿碘中位数为３３６．１０μｇ／Ｌ，≤２０μｇ／Ｌ占检测人数的０．８３％，≥１００μｇ／Ｌ的占９３．６１％；１０３３名新生儿脐带血ＴＳＨ中位数为２．６３ｍＩＵ／Ｌ，＞５．０ｍＩＵ／Ｌ，占检查人数１５．３９％；８～１０岁儿童甲状腺肿大率触诊法（１２００人）为１４．３％，Ｂ超法（１１８５人）１４．９％，两种检查法结果无显著性差异（Ｐ＞０．５）。表现为高尿碘、高肿大率和高ＴＳＨ值，说明了广西居民的碘营养水平近期指标已有明显改善。Nutritious iodine status among children was investigated by cross-sectional study used Population Probability Sampling(PPS)in 30 cities and counties in Guangxi in 1997.The study analyzed goiter rate as well as iodine content in water,salt,urine and thyroid-stimulating hormones(TSH) in umbilical cord blood.The average iodine levels were 2.4 μg/L,41.3 mg/kg in water and salt respectively.Of 1001 salt samples,90.08%,iodine content was above 20 mg/kg.lodine content in rock salt was higher than that in sea salt (P<0.01).The median urinary iodine level from 360 samples was 336.10 μg/L.337 of them was above 100 μg/L.The median blood spot TSH of 1033 neonates was 2.63 mIU/L,in which 15.39% of the samples were above 5.0 mlU/L.172 of 1200 children (14.3%) were diagnosed as goiter by thyroid palpation while 176 of 1185(14.9%) by ultrasonography.The results indicated that iodine deficiency existed in Guangxi and nutritious iodine in residents has obviously improved compared with previous data obtained in 1995.
