2009年四川省雅安市消除碘缺乏病调查结果评价

目的 评估四川省雅安市实现消除碘缺乏病目标情况,掌握全市碘缺乏病防治现状.方法 2009年,按照<四川省实现消除碘缺乏病目标县级考核评估方案>开展县级考评.以县为单位,对8个县(区)的防治资料进行综合评分,并统计分析居民户碘盐监测数据;按东、西、南、北、中5个方位各抽取1个乡(镇),每个乡(镇)各抽取1所小学,每所学校抽取80名8～10岁儿童,触诊法(WS 276-2007)检查甲状腺;收集其中20名8～10岁儿童尿样,砷铈催化分光光度法(WS/T 107-2006)检测含碘量:同时抽取30名5年级学生和该校附近10名家庭主妇,进行碘缺乏病知识问卷调查.结果 8个县(区)资料评分平均为89.96分,范围为85.42～92.90分;居民户碘盐覆盖率为100.00%(2328/2328),碘盐合格率为97.98%(2281/2328),合格碘盐食用率为97.98%(2281/2328);8～10岁儿童甲状腺肿大率为0.91%(33/3620);800名8～10岁儿童尿碘中位数为235.85μg/L,且<50μg/L的占1.50%(12/800);5年级学生和家庭主妇碘缺乏病防治知识问卷调查及格率分别为92.33%(1131/1225)、94.3%(397/421).结论 雅安市以县为单位全部实现消除碘缺乏病目标,但碘缺乏病与碘营养过剩趋势并存,今后应注意每日碘盐食用量的问题,需科学补碘才能持续消除碘缺乏病.

Abstract：

Objective To evaluate the investigation outcome of eliminating iodine deficiency disorders(IDD)in Ya'an city of Sichuan province,and to master the current situation of IDD in the whole city.Methods In 2009,according to"Counties'Assessment Guideline in Sichuan for Implementing the Measure to Eliminate Iodine Deficiency Disorders",assessments were conducted.At county level,composite score was given to collected data of the eight counties(districts)and monitoring data of household iodized salt were statistically analyzed.A township (town)was randomly selected by east,west,south,north and center locations,respectively.One primary school was randomly selected in each selected township(town),eighty children aged 8 to 10 in each selected school were checked of their thyroid by palpation(WS 276-2007)and urinary iodine level of20 children among them was measured by As3+_Ce4+ catalytic spectrophotometry(WS/T 107-2006).Thirty fifth-grade students and 10 housewives lived around school were asked to take a questionnaire survey.Results Average score of the 8 counties(districts)was 89.96,ranged from 85.42 to 92.90.The coverage rate of iodized salt of household was 100.00%(2328/2328),rate of qualified iodized salt was 97.98%(2281/2328).and consumption rate of qualified iodized salt reached 97.98%(2281/2328).The goiter rate of children aged 8-10 was 0.91%(33/3620),median urinary iodine was 235.85μg/L,and 1.50%(12/800)of child's urinary iodine was less than 50μg/L.The rate of passing a knowledge questionnaire survey of the fifth-grade students and women was 92.33%(1 131/1225)and 9413%(397/421),respectively.Conclusions Ya'an city in Sichuan province has reached the goal of eliminating iodine deficiency.disorders,but there is a coexist trend of IDD and iodine excess.They should pay attention to the daily consumption of iodized salt in the future;sustained elimination of IDD can be reached only by iodine supplementation scientifically.
