1995～2002年湖北省碘缺乏病监测结果分析

Analysis of the surveillance results of iodine deficiency disorders in Hubei province from 1995 to 2002

目的了解湖北省碘缺乏病发展动态,探索其影响因素,为防治提供依据.方法按照<全国碘缺乏病监测方案>对8～10岁儿童甲状腺肿大率、尿碘水平和盐碘等指标进行流行病学调查.结果8～10岁儿童甲状腺肿大率1995、1997、1999和2002年分别为6.2%、5.1%、7.4%和6.5%;儿童尿碘中位数分别为233.4、390.8、331.2和197.0μg/L;居民户碘盐合格率分别为47.8%、86.4%、90.2%、93.5%;学生健康教育平均分1997、1999、2000年分别为70.0、63.5、53.6.结论湖北省碘盐质量逐年提高,覆盖率稳定在较高水平;人群碘营养逐步改善,但健康教育平均分呈逐年下降趋势,应引起高度重视.

Objective To understand the variation of iodine deficiency disorders (IDD) and its effect factors for the reference of prevention and cure. Methods According to 'National IDD Surveillance Project', the thyroid goiter rate (TGR) of children, the level of iodized salt and urinary iodine etc were detected. Results The prevalence rates of goiter in children aged 8-10 in 1995,1997,1999 and 2002 were 6.2%, 5.1% ,7.4% and 6.5%, respectively. The medians of the urinary iodine in the same years were 233.4,390.8,331.2 and 197.0 μg/L, respectively. The up to grade rate of the iodized salt in the same years were 47.8%, 86.4% ,90.2% and 93.5%, respectively. The average of health education in 1997,1999,2002 were 70.0,63.5 and 53.6, respectively. Conclusions With the iodized salt supply popularizing and its quality improving, the iodine nutritional level in population has been improved. However we should attach great importance to the progressive decline of averages core for health education.
