目的了解陕西省安康市碘缺乏病防治现状,为防治碘缺乏病提供科学依据。方法 2012年按照《陕西省碘缺乏病监测方案》,盐样采用直接滴定法测定(GB/T 13025.7-1999)。抽查8～10岁学生进行甲状腺检查,诊断标准采用(WS276-2007)进行。10县(区)分农村、城镇两层次进行学龄儿童尿碘测定,采用砷铈催化分光光度法(WS/T107-2006)。随机抽取小学5年级学生30名进行健康问卷调查,抽取学校所在地家庭主妇15名进行健康教育问卷调查和家中食用盐半定量检测。结果共检测居民盐样3 000份。盐碘中位数为29.74 mg/kg,碘盐覆盖率为100.00%(3 000/3 000),合格碘盐食用率为96.63%(2 989/3 000)。触诊法共调查2 100名儿童甲状腺,甲状腺肿大57人,甲状腺肿大率2.71%(57/2 100)。共测定1 200名儿童尿样,尿碘中位数为235.00μg/L,尿碘范围82.10～478.40μg/L。对360名学生和180名家庭主妇进行了健康教育问卷调查,学生及家庭主妇碘缺乏病防治知识知晓率分别为66.76%(721/1 080)、67.22%(363/540),家中食用盐测定,合格碘盐食用率为100.00%(180/180)。结论安康市已达到消除碘缺乏病目标,在实行新的食用碘盐含量标准后,需要继续加强碘缺乏病监测和健康教育工作,对巩固碘缺乏病防治效果有积极意义。
Objective To understand the status of prevention and treatment of iodine deficiency disorders in Ankang City, Shaanxi Province, and to provide a scientific basis for prevention and treatment of iodine deficiency disorders. Methods In 2012, according to “Monitoring Scheme of Iodine Deficiency Disorders in Shaanxi Province”, salt samples were determined by direct titration (GB / T 13025.7-1999). Check the students aged 8 to 10 thyroid examination, diagnostic criteria (WS276-2007). Urine iodine was measured in school-age children at two levels in 10 counties (districts) by using arsenic and cerium catalytic spectrophotometry (WS / T107-2006). A total of 30 primary fifth grade students were randomly selected for health survey and 15 housewives were selected for health education questionnaire and semiquantitative detection of edible salt at home. Results A total of 3 000 salt samples were tested. The median salt iodine was 29.74 mg / kg, the iodized salt coverage was 100.00% (3 000/3 000), and the acceptable iodine salt consumption rate was 96.63% (2 989/3 000). A total of 2 100 children with thyroid gland and 57 goiter were investigated by palpation. The rate of goiter was 2.71% (57/2 100). A total of 1,200 children were measured urine samples, urinary iodine median was 235.00μg / L, urinary iodine range of 82.10 ~ 478.40μg / L. A questionnaire survey on health education among 360 students and 180 housewives was conducted. The awareness rate of prevention of iodine deficiency disorders among students and housewives was 66.76% (721/1 080) and 67.22% (363/540), respectively. , Qualified iodized salt consumption rate of 100.00% (180/180). Conclusion Ankang City has reached the goal of eliminating iodine deficiency disorders. After implementing the new standards of iodized salt content, it is necessary to continue to strengthen the monitoring and education of iodine deficiency disorders, which is of great significance to consolidate the prevention and control of iodine deficiency disorders.
