目的评价阜阳市食盐加碘防治碘缺乏病(IDD)的效果,为持续开展碘缺病防治工作提供依据。方法按照《安徽省碘缺乏病防治监测方案》,使用PPS抽样法,在全市抽取30所小学l200名8~l0岁儿童进行甲肿率调查和尿碘含量检测。采用批质量保证抽样法抽取加工批发、销售、居民户盐样,用直接滴定法测定盐碘含量。抽取四、五年级学生和家庭主妇进行IDD知识问卷调查。结果儿童甲肿率由1995年碘盐防治前的38.30%下降到2008年的1.08%;尿碘中位数由1995年的76ug/L上升到2008年的251ug/L。碘盐合格率、碘盐覆盖率、合格碘盐食用率连续10年在97%以上。四、五年级学生和家庭主妇IDD防治知识平均及格率分别为96.08%和87.14%,行为正确率分别为87.47%和90.71%。结论阜阳市实施全民食盐加碘防治IDD工作成效显著,效果巩固,已连续10年达到消除IDD目标。
Objective To evaluate the effect of iodized salt prevention and treatment of iodine deficiency disease (IDD) in Fuyang City, and provide evidence for the prevention and treatment of iodine deficiency disorders. Methods According to “Anhui Province iodine deficiency disease prevention and treatment monitoring program”, using PPS sampling method, 30 primary schools in the city of l200 children aged 8 to l0 were surveyed for the determination of the rate of goiter and urinary iodine content. Using batch quality assurance sampling method for the processing of wholesale, sales, household salt samples, determination of salt iodide content by direct titration. Fourth and fifth grade students and housewives were asked to conduct IDD knowledge surveys. Results The rate of children with toothache dropped from 38.30% in 1995 before iodized salt prevention to 1.08% in 2008; the median of urinary iodine increased from 76ug / L in 1995 to 251ug / L in 2008. Iodized salt pass rate, iodized salt coverage, qualified iodized salt consumption rate of 97% or more for 10 years. The average passing rate of IDD prevention and control knowledge of fourth and fifth grade students and housewives was 96.08% and 87.14% respectively, and the correct rates of behaviors were 87.47% and 90.71% respectively. Conclusion The implementation of universal salt iodization prevention and treatment of IDD in Fuyang City has achieved remarkable results and consolidated its effect and has achieved the goal of eliminating IDD for 10 consecutive years.
