目的通过系统监测,掌握广西碘缺乏病防治工作现况,为制定切实有效的防控策略提供科学依据。方法按照国家和自治区的方案,在全区109个县(区)开展碘盐监测、人群碘营养监测、居民饮用水水碘监测和健康教育;采用分层与随机抽样方法抽取33个县(区)开展病情监测;在沿海高危地区5个县(区)开展重点监测。结果碘盐监测,95.41%的县(区)居民合格碘盐食用率>90%;人群碘营养监测,8~10岁儿童尿样10888份,尿碘中位数200.35ug/L、<50ug/L的比例为4.22%,哺乳妇女尿样5434份,尿碘中位数126.15ug/L,孕妇尿样5549份,尿碘中位数131.40ug/L、<150ug/L的比例为57.61%;病情监测,检查8~10儿童3315人,甲肿率0.81%;居民饮用水水碘监测,采集并检测水样7554份,<10ug/L的占86.17%,10~150ug/L的占13.79%,>150ug/L的占0.04%;健康教育,一级目标人群的知晓率平均由70.23%上升到94.68%,二级目标人群的知晓率平均由81.60%上升到95.87%。结论广西碘缺乏病处于可持续消除状态。食盐加碘含量调整后,一般人群、哺乳妇女的碘营养处于适宜状态,孕妇碘营养处于不足的状态。需要加大力度和投入开展相关研究,为保证特殊人群碘营养适宜探寻有效措施。
Objective To monitor the status of iodine deficiency disorders in Guangxi through systematic monitoring and provide a scientific basis for the formulation of effective prevention and control strategies. Methods Iodine salt monitoring, iodine nutrition monitoring in population, iodine monitoring of drinking water for residents and health education were carried out in 109 counties (districts) of the whole district in accordance with the plans of the state and autonomous regions. 33 counties (districts) were sampled by stratified and random sampling methods ) To carry out disease surveillance; high-risk coastal areas in five counties (districts) to carry out the key monitoring. Results Iodine salt monitoring showed that 95.41% of residents in county (district) were eligible for iodized salt consumption rate> 90%; 10,988 urine samples of children aged 8-10 years, urinary iodine median 200.35ug / L, <50ug / L ratio was 4.22%, lactation women 5434 urine samples, urine iodine median 126.15ug / L, pregnant women 5549 urine iodine median 131.40ug / L, <150ug / L ratio was 57.61%; The condition monitoring and examination were performed on 3315 children aged from 8 to 10 with a rate of 0.81% of goiter. Drinking water iodine was monitored and 7554 water samples were collected and tested, accounting for 86.17% and 10 ~ 150ug / L, accounting for 13.79% , And> 150ug / L accounted for 0.04%. In the aspect of health education, the awareness rate of primary target population increased from 70.23% to 94.68% on average, and the awareness rate of secondary target population increased from 81.60% to 95.87% on average. Conclusion Guangxi iodine deficiency disorders are in a state of sustainable elimination. Salt iodized content adjustment, the general population, breast-feeding women’s iodine nutrition in the right state, iodine deficiency in pregnant women in inadequate state. Need to increase efforts and put into carrying out relevant research, in order to ensure appropriate iodine nutrition for special populations to explore effective measures.
