目的评价焦作市消除碘缺乏病目标完成情况,总结防治经验,为制定“十三五”规划提供依据。方法按照全国《重点地方病控制和消除评价办法》,查看碘缺乏病管理资料,分别采集居民户盐样、8-10岁儿童和孕妇尿样,触诊法检查儿童甲状腺肿大情况,直接滴定法测定盐碘,砷铈催化分光光度法测定尿碘。结果各县(市、区)组织管理评价得分合计均在85分以上;合格碘盐食用率全市为92.41%,一个县(区)小于90%;8-10岁儿童甲状腺肿大率均小于5%,尿碘中位数在174.45~231.47μg/L之间,尿碘水平低于50μg/L的比例最高为10.00%;孕妇尿碘中位数在131.60~203.85μg/L之间。结论焦作市各县(市、区)消除碘缺乏病工作机制得到进一步完善,但消除碘缺乏病成果不稳固,一个县(区)合格碘盐食用率和四个县(区)孕妇尿碘水平未达到消除标准,下一步要加强碘盐管理、密切关注重点人群碘营养状况变化,及时调整防治策略,持续消除碘缺乏病。
Objective To evaluate the goal of eliminating iodine deficiency disorders in Jiaozuo City and to sum up experience in prevention and treatment so as to provide the basis for formulating the “13th Five-Year Plan”. Methods According to the national “Key endemic disease control and elimination evaluation methods”, the data of iodine deficiency disorders management were reviewed. The samples of urine samples from residents, urine samples of 8-10 years old and pregnant women, palpation of children with thyroid enlargement were detected by direct titration Determination of iodine, arsenic and cerium catalytic spectrophotometric determination of urinary iodine. Results The scores of organization management evaluation of all counties (cities, districts) were all above 85 points. The eligible rate of qualified iodized salt in the whole city was 92.41%, less than 90% in one county (district); the rate of goiter in children aged 8-10 was less than 5 %, Median urinary iodine between 174.45 ~ 231.47μg / L, urinary iodine levels below 50μg / L the highest proportion of 10.00%; pregnant women urinary iodine median between 131.60 ~ 203.85μg / L. Conclusion The work mechanism of elimination of iodine deficiency deficiency in counties (cities and districts) in Jiaozuo has been further improved. However, the results of eliminating iodine deficiency disorders are not stable. The iodine salt consumption rate of one county (district) and the iodine level of pregnant women in four counties Did not meet the elimination criteria, the next step should be to strengthen the management of iodized salt, pay close attention to changes in key populations of iodine nutrition, timely adjustment of prevention and control strategies to continue to eliminate iodine deficiency disorders.
