摘要目的 了解浙江省淳安县碘缺乏病病情,为因地制宜,科学补碘提供科学依据.方法 2006,2007年在淳安县选掸病情最重的3所小学(汪宅乡,屏门乡和文昌镇各1所小学),每所小学抽取90名8-10岁学生进行甲状腺B超检查,采集学生尿样测定尿碘,采集学生家庭食用盐样,定量检测盐碘.结果 2006年B超检查8-10岁儿童267人,甲状腺肿大(简称甲肿)率为7.5%(20/267),尿碘中位数为247.5μg/L,盐碘均数为32.7 mg/kg,2007年B超检查8-10岁儿童271人,甲肿率为3.7%(10/271),尿碘中位数为383.4μg/L,盐碘均数为33.5 mg/kg.2006年汪宅乡,屏门乡和文昌镇甲肿率分别为15.2%(14/92),6.0%(5/83)和2.2%(2/92).尿碘中位数分别为360.1,211.3,189.3μg/L,2007年汪宅乡,屏门乡和文昌镇甲肿率分别为6.6%(6/91),3.3%(3/90)和1.1%(1/90),尿碘中位数分别为388.6,411.5,327.8μg/L.2006年调查汪宅乡,屏门乡和文昌镇的人均年收入分别为1000,2000,3000元.结论 病情严重程度与经济状况,尿碘有关,营养因素在甲肿发生中的作用不容忽视,在营养水平较低的基础上,尿碘过高导致了较高的甲肿率.

abstractsObjective In order to compare the iodine deficiency disorders(IDD)prevalent slatus in Chun'an County between 2006 and 2007,and to provide the science information for iodine supplementation in different regions.Methods Three schools of Wangzhai,Pingmen and Wenchang which the goiter prevalenee was the most severe were selected in Chun'an County;and from each school,90 pupils aged 8-10 years were randomly selected.B-ultrasound examination of thyroids,urine iodine and salt iodine were measured.Results The goiter rate in B-ultrasound were 7.5%(20/267),median of urine iodine was 247.5 μg/L,mean of salt iodine was 32.7 ms/ks in 2006;and the goiter rate in B-uhrasound were 3.7%(10/271),median of urine iodine was 383.4 μg/L,mean of salt iodine was 33.5 mg/kg in 2007.The goiter prevalence in Wangzhai,Pingrnen and Wenehang township were 15.2%(14/92),6.0%(5/83)and 2.2%(2/92),respectively,and median of urine iodine were 360.1.211.3,189.3μg/L,respectively,in 2006;The goiter prevalence were 6.6%(6/91),3.3%(3/90)and 1.1%(1/90),respectively.and median of urine iodine were 388.6,41 1.5,327.8μg/L,respectively,in 2007.Family ineome of Wangzhai,Pingmen and Wenchang township were 1000,2000,3000 yuan,respectively.Conclusions Goiter prevalence was correlated with urinary iodine,nutritional state and economic condition,high urinary iodine contents and poor nutritional status lcad to a high goiter rate.
