目的通过对新疆碘缺乏病高危地区8-10岁儿童碘营养状况监测,对照国家相关标准进行碘缺乏病防治工作评价,为进一步完善与调整该疾病区域性防控策略提供科学依据。方法根据新疆碘缺乏病防控方案,抽取南部17个县(市)进行监测,现场B超检查甲状腺肿大情况,同时采集尿样和家庭食用盐样品,进行实验室尿碘含量、盐碘定量的测定。结果调查8-10岁儿童4 127名,发现甲状腺肿大人数68人,甲状腺肿大率为1.65%,尿碘中位数为191.11μg/L;采集食用盐5 100份,居民合格碘盐食用率91.96%。结论 2013年新疆南部5地(州)17个县8-10岁儿童碘营养状况良好,各项指标达到县级碘缺乏病消除标准,但传统病区仍有甲状腺代偿性肿大病例发生,说明应持续建立、健全消除碘缺乏病工作机制,不断提高防治成效。
Objective To monitor the iodine nutrition status of children aged 8-10 years old in high risk areas of iodine deficiency disorders in Xinjiang and evaluate the prevention and control of iodine deficiency disorders according to relevant national standards so as to provide scientific basis for further improving and adjusting the regional prevention and control strategies of this disease. Methods According to the prevention and control program of iodine deficiency disorders in Xinjiang, 17 counties (cities) in southern China were sampled for monitoring. The results of thyroid enlargement were examined by on-site B-mode ultrasonography. Urine samples and household salt samples were also collected for urine iodine and iodine The determination. Results A total of 4 127 children aged 8-10 years were investigated. The number of goiter patients was 68, the rate of goiter was 1.65% and the median of urinary iodine was 191.11 μg / L. Five hundred salt samples were collected, Rate of 91.96%. Conclusion In 2013, the iodine nutrition status of children aged 8-10 in 17 counties of 5 places (prefectures) in southern Xinjiang was good, and all indexes reached the standard of eliminating iodine deficiency disorders at the county level. However, there were still thyroid compensatory enlargement cases in traditional wards, It shows that we should continue to establish and improve the working mechanism of eliminating iodine deficiency disorders and continuously improve the effectiveness of prevention and treatment.
