目的评价绵阳市基本消除碘缺乏病4年来全市的碘缺乏病防治效果,了解绵阳市城乡居民碘营养状况,及时发现问题并采取相应干预措施。方法四川省疾病预防控制中心按PPS法抽取的绵阳市游仙区进行碘缺乏病病情监测,在该区抽取400名8~10岁儿童检测其甲状腺肿大率和其中50人的尿碘及家庭盐碘;抽取40岁以下育龄妇女、孕妇、哺乳期妇女及其0~2岁婴幼儿各50人检测尿碘和食用盐碘;抽取18个库盐样品检测盐碘;抽取10份饮用水水样检测水碘。在该市所有9个县区,抽取2 700份居民食用盐检测盐碘。结果B超法检查8~10岁儿童甲肿率为4.60%,校正肿大率4.52%,甲状腺容积在1.2~7.2 mm3之间。8~10岁儿童、40岁以下育龄妇女、孕妇、哺乳期妇女及其0~2岁婴幼儿尿碘中位数分别为116.2、110、101.4、189.6、199.6μg/L,<50μg/L比例分别为14%、4%、12%、0%、0%。水碘为0.78~13.07μg/L,水碘中位数为4.64μg/L。该市合格碘盐率为99.45%,合格碘盐食用率为99.42%;监测点合格碘盐率为98.5%,合格碘盐食用率为98.5%,库盐合格率为100%。结论绵阳市合格碘盐覆盖率高,人群整体碘营养状况良好,但孕妇碘营养水平偏低,应加强针对性的健康教育和补碘。
Objective To evaluate the prevention and control of iodine deficiency disorders in Mianyang City in the past four years after eliminating iodine deficiency disorders in Mianyang City. To understand the iodine nutrition status of urban and rural residents in Mianyang City, the problems were found in time and relevant intervention measures were taken. Methods The Sichuan Provincial Center for Disease Control and Prevention monitored the iodine deficiency disease in Youxian District of Mianyang City by PPS method. 400 children from 8 to 10 years old were collected to detect the goiter rate and 50 of them to urinary iodine and their families Salt iodine; urinary iodine and salt iodine were collected from 50 women of childbearing age, pregnant women, lactating women and their 0 to 2 years old infants under 40 years of age; 18 salt and saline samples were taken to detect salt and iodine; 10 drinking water Sample test of water iodine. In all 9 districts and counties in the city, 2,700 residents of table salt were taken to measure salt iodine. Results The results of ultrasonography showed that the children with 8-10 years old had a rate of 4.60%, corrected swollen rate 4.52%, and thyroid volume 1.2 ~ 7.2 mm3. The median urinary iodine of children aged 8-10 years, women of childbearing age under 40, pregnant women, lactating women and their infants aged 0 ~ 2 years were 116.2,110,101.4,189.6,199.6μg / L, respectively, <50μg / L Respectively, 14%, 4%, 12%, 0%, 0%. Water iodine was 0.78 ~ 13.07μg / L, water iodine median was 4.64μg / L. The qualified iodized salt rate of the city was 99.45%, and the qualified iodized salt consumption rate was 99.42%. The qualified iodized salt rate of the monitoring point was 98.5%, the qualified iodized salt consumption rate was 98.5% and the library salt pass rate was 100%. Conclusion The coverage of qualified iodized salt in Mianyang City is high, and the overall iodine nutrition status of the population is good. However, the iodine nutrition level of pregnant women is low, and targeted health education and iodine supplement should be strengthened.
