摘要
目的综合分析2006—2016年重庆市长寿区盐碘含量、尿碘含量、甲状腺肿大率等监测数据,为巩固长寿区消除碘缺乏病成果、掌握碘缺乏病病情及流行趋势、动态评价人群碘营养状况提供依据。方法对全区居民按东、西、南、北、中划分5个抽样片区,随机抽检居民食用盐,按照GB/T 13025.7直接滴定法(川盐及其它强化食用盐采用仲裁法)测定盐中碘含量。儿童甲状腺肿大采用触诊法或B超法,尿碘采用砷铈催化分光光度方法测定。结果 2006—2016年长寿区共监测居民户盐样3 660份,非碘盐率1.58%,碘盐合格率94.06%,碘盐覆盖率98.42%,合格碘盐食用率92.57%,碘盐中位数28.63mg/kg。儿童尿碘中位数255.35μg/L,甲状腺触摸法肿大率4.39%、B超法3.38%。孕妇尿碘中位数203.02μg/L。结论长寿区人群碘营养水平基本处于适宜水平,各项碘缺乏病监测指标均位于国家控制指标以内,达到消除碘缺乏病标准。
Objective To comprehensively analyze the monitoring data of Urinary iodine,Salt iodine and goiter rate in Changshou District during 2006- 2015,consolidated the results of the elimination of iodine deficiency disorders and comprehend the growth and decline trend of iodine deficiency disorders in Changshou District,provide basic information for dynamic assessment of iodine nutritional status in the population. Methods The region of residents according to the East,West,South,North,were divided into five sampling area,a random sampling of residents in edible salt by direct titration quantitative determination of iodine content according to GB / T 13 025. 7,the goiter by touching or ultrasonography,urinary iodine by arsenic cerium catalytic spectrophotometric method. Results 3 660 salt samples were collected during 2006- 2015,non-iodlized salt rate was 1. 58%,iodlized salt qualification rate was 94. 06%,iodlized salt coverage rate was 98. 42%,iodlized salt consumption rate was 92. 57%,and salt median iodine was 28. 63 mg / kg. Urinary iodine median of children was 255. 35μg / L,goiter was 4. 39% by touching and 3. 38% by ultrasonography,salt median iodine of children’s family was 29. 4mg / kg. Urinary iodine median of pregnant women was 203. 02 μg /L. Conclusion The iodine nutrition level of the people in Changshou District was basically in the appropriate level,all the monitoring indicators were lower than the general level,satisfied the elimination standard of IDD.
