厦门市消除碘缺乏病目标区级考评结果分析

Analysis of district-level evaluation results after reaching the goal of eliminating iodine deficiency disorders in Xiamen city

目的了解厦门市实现消除碘缺乏病阶段目标后病情变化情况,评价防治措施效果,为下一步制订防治策略提供依据。方法按照《福建省实现消除碘缺乏病目标县级考核评估实施细则》的要求2,009年对厦门市的6个区开展组织领导、碘盐管理、监测与防治、健康教育(简称4项管理指标)的检查;以区为单位,每个区按东、西、南、北、中5个方位抽取1个镇(镇数在5个以下的区则全部抽取),每个镇各抽查1所小学,每所小学抽取8～10岁学生40名以上进行甲状腺检查,其中抽取20名学生尿样,进行尿碘测定。按照全国碘缺乏病监测方案的要求,以区为单位,抽取居民食用盐,进行盐碘测定。儿童甲状腺检查使用触诊法,盐碘测定用直接滴定法,尿碘测定用砷铈催化分光光度法。结果全市的4项管理指标标化后平均得分为93.1分;8～10岁儿童校正甲状腺肿大率为1.7%,尿碘中位数为186.7μg/L,<50μg/L的比例为2.9%;碘盐覆盖率为99.0%,碘盐合格率99.2%,居民合格碘盐食用率为98.3%,非碘盐率为1.0%。结论厦门市各项指标达到国家消除碘缺乏病标准,要坚持全民食盐加碘综合防治措施,继续开展碘营养监测和健康教育宣传,指导科学补碘。

Objective To explore the change in the state of iodine deficiency disorders（IDD） after achieving the stage goal of eliminating IDD in Xiamen city and to evaluate the effect of prevention and treatment measures,provide scientific basis for the development of control strategies.Methods There were 6 districts in the city,and each district as a unit was to carry out the inspection for organization and leadership,iodine salt management,monitoring and control,health education（referred to as the four management indicators） according to ＂the county-level assessment and evaluation implementation detailed rules of realizing the goal to eliminate IDD in Fujian province＂.According to the east,west,south,north and middle position in each district,a village and a primary school were selected.If there were less than five towns in the district,all towns have been selected.Forty 8 to 10 years old children in each school were randomly selected to check thyroid and among them 20 children were collected urine samples to determine urinary iodine.According to national monitoring standard of IDD,the household salt in each district were collected to test salt iodine,checking the 8 to 10 years old children＇s goiter situation by palpation,determining the salt-iodine by direct titration,determining the urine-iodine by arsenic cerium catalytic spectrophotometry.Results The average scores of the four management indicators was 93.1 in Xiamen city.The adjusted goiter rate of children aged 8 to 10 years old was 1.7%.The urinary median iodine was 186.7 μg/L,the proportion of urine-iodine level 50 μg/L was 2.9%;The coverage rate of iodized salt was 99.0%,the qualified rate of iodized salt was 99.2%,the edible qualified iodinated salt rate was 98.3%,and the rate of non-iodized salt was 1.0%.Conclusions All the indicators have reached the national standard to eliminate IDD in Xiamen city.We must insist on intaking qualified iodine salt,carring out supervision,health publicity and education.
