对日照市１９８２～１９９４年碘缺乏病区的地甲肿患病率、肿大率及水碘、尿碘、盐碘动态进行监测。结果表明：自１９８３年向病区供应碘盐后，居民尿碘均值明显上升并维持在１００ｕｇ／Ｌ以上，地甲肿患病率、肿大率由原来的１１．０７％和３６．９５％下降到１９８９年的０．８６％和４．８３％。１９９１年后居民尿碘水平开始下降，至１９９３年尿碘值＜１００ｕｇ／Ｌ者占５４．８％，居民户食盐平均含碘量为０．７７～１１．５６ｍｇ／ｋｇ，无碘率高达３２．４％，学龄儿童甲状腺肿大率呈回升趋势。建议应重点加强对病区碘盐供应工作的监督管理措施
The prevalence rate, enlargement rate and iodine, urinary iodine, salt and iodine dynamics of iodine deficiency area in Rizhao City from 1982 to 1994 were monitored. The results showed that after iodized salt was supplied to the ward in 1983, the average urinary iodine value of residents increased significantly and remained above 100 ug / L. The prevalence rate of gestation and swelling ranged from 11.07% and 36.95% Dropped to 0.86% and 4.83% in 1989. After 1991, the urinary iodine level of residents began to decline. By 1993, the urinary iodine value <100ug / L accounted for 54.8%. The average iodine content of household salt was 0.77 ~ 11.56mg / kg, and the non-iodine rate was as high as 32 .4%, school-age children’s goiter rate showed a rising trend. Suggestions should be focused on strengthening the monitoring and management of iodized salt supply in the ward
