目的考核各县(区)消除碘缺乏病技术指标,为内江市实现消除碘缺乏病目标提供科学依据。方法各县(区)随机抽取居民户食用盐288份,采用GB/T13025.7-1999仲裁法进行实验室定量检测;随机抽取8～10岁儿童400名采用触诊法(按照WS276-2007)检查甲状腺;同时随机抽取100份学生尿样,采用砷铈催化分光光度方法(WS/T107-2006)测定尿碘浓度;随机抽取五年级学生150名,在学校附近抽取家庭主妇50名,采用答(问)卷调查健康教育知晓情况。结果内江市5县(区)居民合格碘盐食用率在95.14%～100.00%之间,均>90%;碘盐覆盖率在97.22%～100.00%之间,均>95%;8～10岁儿童甲状腺肿大率在2.25%～4.50%之间,均<5%;8～10岁儿童尿碘含量中位数在260.50～288.40ug/L之间,且尿碘含量低于50ug/L的比例在5%～10%之间,均<20%;五年级学生碘缺乏病知识知晓率在93.33%～99.33%之间,均>90%;学校附近家庭主妇碘缺乏病知识知晓率在88.00%～98.00%之间,均>85%。结论内江市5县(区)消除碘缺乏病技术指标符合《四川省实现消除碘缺乏病目标县级考核评估方案》的要求。
Objective To assess the technical indicators of eliminating iodine deficiency disorders in all counties (districts) and provide a scientific basis for achieving the goal of eliminating iodine deficiency disorders in Neijiang. Methods A total of 288 samples of household edible salt were randomly selected from all counties (districts), and laboratory quantitative tests were carried out using the arbitration method of GB / T13025.7-1999. 400 children aged 8 to 10 years were randomly selected by palpation (according to WS276-2007) Check the thyroid gland; at the same time, 100 samples of urine of students were randomly selected, and urinary iodine concentration was determined by arsenic cerium catalytic spectrophotometry (WS / T107-2006); 150 fifth graders were randomly selected and 50 housewives were drawn near the school. (Q) survey of health education to understand the situation. Results The eating rates of qualified iodized salt of residents in 5 counties (districts) in Neijiang City ranged from 95.14% to 100.00%, both of which were> 90%. The coverage of iodized salt was more than 95% between 97.22% and 100.00% The prevalence of goiter in children was between 2.25% and 4.50%, both <5%. The median urinary iodine content of children aged 8-10 was between 260.50 and 288.40ug / L, and the urinary iodine content was lower than 50ug / L The awareness rate of Iodine Deficiency Disorders in Grade 5 students ranged from 93.33% to 99.33%, both of which were higher than 90%. The awareness rate of housewife’s iodine deficiency disorders near the school was 88.00 % ~ 98.00%, all> 85%. Conclusion The technical indicators of eliminating iodine deficiency disorders in 5 counties (districts) in Neijiang City meet the requirements of “the county-level appraisal scheme for eliminating iodine deficiency disorders in Sichuan Province”.
