广西2011年碘缺乏病监测结果分析

Analysis on surveillance results of iodine deficiency disorders in Guangxi in 2011

目的了解广西碘缺乏病防治工作现况,为制定预防控制策略提供科学依据。方法采用PPS法抽取30个县、区开展病情监测;在未开展病情监测的79个县、区进行人群碘营养监测;在全区109个县、区开展系统地饮用水水碘监测。结果病情监测,碘盐覆盖率为99.43%,合格碘盐食用率为93.54%,8~10岁儿童甲肿率为0.33%,尿碘中位数236.60μg/L,孕妇和哺乳妇女尿碘中位数均为131.00μg/L;人群碘营养监测,8~10岁儿童尿样7 838份,尿碘中位数241.77μg/L,〈50μg/L的比例为2.76%,〉300μg/L比例33.50%;饮用水水碘监测,全区4 968份居民生活饮用水水碘检测,〈10μg/L占84.74%,10~150μg/L占14.94%,〉150μg/L占0.32%。结论广西属于缺碘地区,普及碘盐防治碘缺乏病的效果得到进一步夯实,人群碘营养总体上在适宜范畴,但处于一种大于需要量的状态,需要对我区食盐加碘含量进行科学调整。

Objective To understand the prevention and control condition of iodine deficiency disorders（ IDD） in Guangxi,and to provide scientific references for controlling IDD. Methods 30 counties were sampled to carry out illness monitoring by PPS method, and the other 79 counties to monitor iodine nutrition. All the 109 counties were monitored the concentration of iodine in drinking water. Results Illness monitoring： The coverage rate of iodized salt was 99. 43%, and the consuming rate of qualified iodized salt was 93. 54%. The goiter rate of children aged 8 to 10 years old was 0. 33%. The median urinary iodine of children was 236. 60 μg / L, and 131. 00 μg / L in pregnant and lactating women. Iodine nutrition monitoring： 7 838 8 to 10 years old children＇s urines were tested, the median of urinary iodine was 241. 77 μg / L. The proportion below 50 μg / L was 2. 76% and above 300 μg / L was 33. 50%. Drinking water iodine monitoring： 4 968 drinking water were tested. The proportion below 10 μg / L was 84. 74%, between 10 and 150 μg / L was 14. 94%, and above 150 μg / L was 0. 32%. Conclusions Guangxi province belonged to iodine deficiency area, and universaled iodized salt to prevent and control IDD was futher solidified. The iodine nutrition status of people was suitable, but it was at a super sufficient condition. The concentration of salt iodine should be adjusted scientificly in Guangxi.
