目的评价丹棱县碘缺乏病防治效果,为进一步开展碘缺乏病防治工作提供依据。方法收集整理1982-2009年丹棱县碘缺乏病防治工作的相关数据资料,比较其中各项工作开展初期和终期评估阶段时在组织领导、碘盐管理、监测与防治、健康教育4项管理指标,以及盐碘含量、甲状腺肿大率、尿碘水平3类技术指标间的差异。结果丹棱县1982年开始摸底调查碘缺乏病,防治工作限于下发文件、健全机构、开展监测、对重点人群普服碘油丸胶囊。1990年开始推行食用碘盐。1994年全民食用碘盐,开始全民参与消除碘缺乏病的工作。在管理项目中,1994年得56分;2009年得96分。碘盐管理:2004年和2009年,碘盐覆盖率差异有统计学意义(!2=67.19,P<0.05),村民合格碘盐食用率差异有统计学意义(!2=33.90,P<0.05),零售点食用盐合格率差异有统计学意义(!2=5.38,P<0.05),居民户食用盐合格率差异有统计学意义(!2=33.90,P<0.05)。病情监测:7～14岁学生甲状腺肿大率和患病率1989年分别为32.19%、10.24%,1998年为16.00%、2.00%,甲状腺肿大率差异有统计学意义(!2=7.23,P<0.05)、患病率差异有统计学意义(!2=13.75,P<0.05);8～10岁学生尿碘水平逐渐上升,平均中位数1994年为40.63μg/L,2009年为187.37μg/L,1994年和2009年尿碘中位数正常率差异有统计学意义(!2=134.83,P<0.05)。结论丹棱县1982-2009年防治碘缺乏病管理指标得分上升,甲状腺肿大率逐渐下降,8～10岁学生尿碘水平逐渐上升,到2009年各项指标均达到国家消除碘缺乏病的要求,丹棱县碘缺乏病防治效果显著。
Objective To evaluate the prevention and treatment effect of iodine deficiency disorders in Danling County and provide the basis for further prevention and control of iodine deficiency disorders. Methods The related data of iodine deficiency disorders prevention and treatment in Danling County from 1982 to 2009 were collected and compared among the four phases of management including organization and leadership, management of iodized salt, monitoring and prevention, and health education during the initial and final stages of assessment. Indicators, as well as salt iodine content, goiter rate, urinary iodine levels of three kinds of technical indicators of differences. Results Danling County in 1982 began a thorough investigation of iodine deficiency disorders, prevention and control work is limited to the issuance of documents, improve the institutions to carry out monitoring, the key population of universal service iodized oil pill capsules. In 1990 began the implementation of iodized salt. In 1994, the whole people consumed iodized salt and started universal participation in eliminating iodine deficiency disorders. In management projects, there were 56 points in 1994 and 96 points in 2009. Iodized salt management: There was significant difference in the coverage of iodized salt in 2004 and 2009 (2 2 = 67.19, P <0.05), and there was significant difference in the eating rate of qualified iodized salt among villagers (2 2 = 33.90, P <0.05 ), And there was a significant difference in the pass rate of edible salt at the retail outlets (! 2 = 5.38, P <0.05). There was a significant difference in the passing rate of edible salt among the households (! 2 = 33.90, P <0.05). Surveillance of disease: The prevalence and prevalence of goiter in 7-14-year-old students were 32.19% and 10.24% respectively in 1989 and 16.00% and 2.00% respectively in 1998. The difference was statistically significant (2 2 = 7.23, P <0.05). The prevalence rate was statistically significant (2 2 = 13.75, P <0.05). Urinary iodine levels gradually increased in students aged 8-10 years with an average median of 40.63 μg / L in 1994 and 187.37μg / L, there was a significant difference in the normal rate of urinary iodine between 1994 and 2009 (! 2 = 134.83, P <0.05). Conclusion The management index of Iodine Deficiency Disorders in Danling County increased from 1982 to 2009, the goiter rate decreased gradually, and the level of urinary iodine in students aged 8 ~ 10 gradually increased. By 2009, all the indicators reached the national requirements of eliminating iodine deficiency disorders , Danleng iodine deficiency disease prevention and treatment effect is remarkable.
