Outcome analysis of surveillance on iodine deficiency disorders in Longyan City in Fujian Province in the year 2006 and 2007

目的了解福建省龙岩市碘缺乏病病情现状，评价防治措施效果，为制订防治策略提供依据。方法2006和2007年期间，在福建省龙岩市7个县（市、区），每个县（市、区）按容量比例概率抽样法（PPS）确定30所小学．每所小学抽取40名8～10岁学生，进行甲状腺触诊检查，同时抽取7名学生采集尿样和家中盐样，进行尿碘及盐碘测定，计算甲状腺肿大率、尿碘中位数、合格碘盐食用率、碘盐覆盖率、碘盐合格率和非碘盐率。结果龙岩市8～10岁儿童甲状腺肿大率为0．94％（79／8438），尿碘中位数为259．12μg／L，合格碘盐食用率为97．86％（1462／1494），碘盐覆盖率为99．46％（1486／1494），碘盐合格率为98．38％（1462／1486），非碘盐率为0．54％（8／1494）。结论龙岩市的碘缺乏病防治工作达到国家消除碘缺乏病标准。

Objective To understand the current situation of iodine deficiency disorders（IDD） in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey（PPS） from the 7 counties of Longyan City. Forty children aged 8 - 10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rate, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8 - 10 years old in Longyan City was 0.94%（79/8438）. The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% （1462/1494）. The iodine salt coverage rate was 99.46% （1486/1494）. The rate of qualified iodized salt was 98.38 （1462/1486）, and the non-iodized rate was 0.54% （8/1494）. Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.
