摘要
目的了解和掌握内蒙古自治区碘缺乏病病情和干预措施落实情况,评价防治效果及人群碘营养状况,为自治区持续消除碘缺乏病工作提供科学依据。方法按＂人口比例概率抽样方法＂（PPS）1995-2011年在自治区抽取30个旗县为监测点,每个监测点用单纯随机抽样法抽取一所学校,每所学校抽取40名8-10岁在校学生检查甲状腺肿大情况,并定量检测其家中盐碘含量,在每个抽样点的40名儿童中抽取12名儿童的尿样测定尿碘。结果儿童甲状腺肿率：触诊法从1995年的22.8%下降到2005年的5.4%;B超法：从1997年6.9%下降至2011年的3.1%。8-10岁儿童尿碘水平：尿碘中位数由1995年160.09μg/L提高到2011年的259.9μg/L。合格碘盐食用率由1995年55.6%提高到98.1%,无碘盐率由1995年的7.7%下降到0.7%。结论自治区以食盐加碘为主的防治碘缺乏病的综合措施成效显著,碘盐覆盖率、合格碘盐食用率,儿童甲状腺肿率、尿碘中位数,达到我国消除碘缺乏病标准,8-10岁儿童碘营养水平处于充足状态。
Objective To investigate the status and implementation of preventive measures of iodine deficiency disorders （IDD） in Inner Mongolia, to evaluate the effect of intervention and to provide scientific basis for the prevention of 1DD. Methods The surveillance was carried out by stratified sampling with probability proportional to size （PPS） during 1995 to 2011. A total of 30 surveillance sites were chosen, one primary school was randomly selected from each site, and 40 students aged 8-10 were sampled from each primary school. The thyroid volume was checked, and the iodine content of edible salt in these students＇ homes was quantitatively determined. A number of 12 students were randomly collected out of 40 students in each site, to test their urinary iodine. Results Strumous ratio of children by palpate method decreased significantly, which was 22.8% in 1995 but 5.4% in 2005; the rate obtained by B ultrasonic method was 6.9% in 1995 but dropped to 3.1% in 2011. The median of urinary iodine was 160.09 μg/L in 1995 and 259.9 μg/L in 2011. The rate of qualified iodized salt rose from 55.6% in 1995 to 98.1% in 2011. The rate of non-iodized salt dropped from 7. 7% in 1995 to 0.7% in 2011. Gonclusions After salt iodization as the main measure in the prevention and control of iodine deficiency disorders, remarkable progress has been made in Inner Mongolia. The coverage of iodized salt rate, the consumption of iodized salt, goiter rate, and UI median have reached the elimination standard of iodine deficiency disorders. Children aged 8-- 10 have sufficient iodine nutrition.
