目的评价丹东市碘缺乏病防治效果,为制定和完善防治对策提供科学依据。方法采取按人口容量比例概率抽样方法对8~10岁儿童甲状腺肿大率、尿碘水平、碘盐合格率、覆盖率等指标进行流行病学调查。结果 1998—2006年8~10岁儿童甲状腺肿大率分别为11.09%、9.61%、7.75%、5.70%、4.49%、4.23%、3.66%、2.94%;尿碘中位数分别为164.6μg/L、284.9μg/L、199.46μg/L、164.93μg/L、138.65μg/L、153.54μg/L、168.79μg/L、154.26μg/L;碘盐合格率分别为88.42%、86.85%、91.50%、94.17%、95.87%、96.70%、97.94%、99.20%;覆盖率分别为82.95%、86.50%、88.63%、92.23%、93.98%、96.1%、98.13%、98.60%。结论实施全民食盐加碘干预措施以后,儿童甲状腺肿大率逐年下降,人群碘营养水平得到提高,碘缺乏病防治效果显著。
Objective To evaluate the effect of iodine deficiency disorders in Dandong City and provide a scientific basis for formulating and improving prevention and treatment measures. Methods According to the population sampling method, the epidemiology of goiter, urinary iodine, qualified rate of iodized salt and coverage of children aged 8-10 years were collected. Results The goiter rates of children aged 8-10 years old from 1998 to 2006 were 11.09%, 9.61%, 7.75%, 5.70%, 4.49%, 4.23%, 3.66% and 2.94%, respectively. The urinary iodine median was 164.6μg / L, 284.9μg / L, 199.46μg / L, 164.93μg / L, 138.65μg / L, 153.54μg / L, 168.79μg / L and 154.26μg / L respectively.The qualified rates of iodized salt were 88.42%, 86.85%, 91.50 The coverage rate was 82.95%, 86.50%, 88.63%, 92.23%, 93.98%, 96.1%, 98.13%, 98.60% respectively. Conclusion After the intervention of universal salt and iodine intervention, the rate of goiter in children declines year by year, the level of iodine nutrition in the population is improved, and the prevention and treatment of iodine deficiency disorders is remarkable.
