苏州市吴江区消除碘缺乏病后2001～2011年监测结果分析

目的 分析苏州市吴江区2001～2011年碘缺乏病监测情况,掌握动态变化趋势,评价防治效果,为持续消除碘缺乏病提供科学依据.方法 根据省市有关碘盐监测和调查评估方案,采用碘盐监测、病情监测及综合监测方法.结果 2008～2011年的碘盐覆盖率≥95％,差异无统计学意义（P＞o.05）,2007年以后碘盐合格率呈上升趋势,差异有统计学意义（P ＜0.05）;8～10周岁儿童甲状腺肿大率为0.83％（均＜5％）,2007年、2009年出现降低趋势,差异有统计学意义（P ＜0.05）;8～10周岁儿童尿碘100 μg/L以下的比率在6.25％～16.66％（＜50％）、尿碘50μg/L以下的比率在0～3.00％（＜20％）;特需人群的孕妇和哺乳期妇女尿碘中位数为181.40μgL,尿碘150 μg/L以下的比率占42.86％.结论 吴江区盐碘、尿碘及甲状腺肿大率3项指标均达到国家消除碘缺乏病的标准.11年的监测结果显示,全区碘缺乏病的防治成果得到了进一步巩固.今后应加强特需人群的碘营养监测.

Analysis for the monitoring results after eliminating iodine deficiency disorders during 2001 to 2011 in Wujiang district of Suzhou city

Objective To analyze Wujiang District from 2001 to 2011 to monitor the situation of iodine deficiency dis- orders, grasp the dynamic trends and evaluate control effect ,to provide a scientific basis for sustainable elimination of iodine deficiency disorders. Methods According to the provinces about iodized salt monitoring and investigation and assessment program, used iodized salt monitoring, integrated disease surveillance and monitored methods. Results From 2008 to 2011 of iodized salt coverage ≥95%, the difference was not significant （P 〉0.05）, the passing rate of iodized salt from 2007 showed upward trend, the difference was significant （P 〈0.05）; children with 8-10 years old goiter rate was 0.83%（both 〈5%）, 2007, 2009 year appeared a decreasing trend , the difference was significant （P 〈0.05）; The urine iodine ratio of 100μg/L or less of 8 to 10 year old was 6.25%-16.66%（〈 50%）, urinary iodine was 50μg/L or less was 0 to 3.00%（ 〈20%）; special needs populations pregnant and lactating women median urinary iodine 181.40 μg/L, uri- nary iodine 150 μg / L ratio belowed 42.86%. Conclusion Wujiang district, salt iodine, urinary iodine and goiter three indicators have reached the national standard for eliminating iodine deficiency disorders. Monitoring results showed eleven years ： prevention of iodine deficiency disorders achievements region has been further consolidated. Special needs populations should strengthen monitoring of iodine nutrition .
