【摘要】 目的了解晋北3市(大同、朔州、忻州市)碘缺乏病(IDD)流行现状和现行碘盐浓度的防治效果,为完善消除IDD防治策略提供科学依据。方法每市每年按不同方位随机抽取5所小学及学校所在村为调查点,进行儿童甲状腺肿大率(甲肿率)、尿碘、家中食用盐和水碘、IDD健康教育知识等调查。结果8～10岁儿童甲肿率呈下降趋势,2001、2002和2003年分别为6.52%、5.84%和5.19%,接近国家≤5%的指标。儿童尿碘中位数3年保持在200～300 μg/L,2001、2002和2003年分别为253.96、240.30和265.59 μg/L;其中42.8%的尿样尿碘>300 μg/L,提示碘过量。居民合格碘盐食用率稳中有升,2001、2002和2003年分别为88.0%、90.0%和94.1%,后2年达到国家消除IDD食用碘盐指标。结论晋北3市实施现行碘盐标准防治IDD取得了预期效果,儿童甲肿率、尿碘和居民合格碘盐食用率达到了国家消除IDD标准要求,IDD得到了有效控制。更多还原

【Abstract】 Objective To provide a scientific basis for improving the policy for the prevention and control of iodine deficiency disorders(IDD) by investigating the IDD epidemic situation and the prevention and control of the present iodized salt density in the three cities of North Shanxi Province. Methods Five primary schools and their villages were randomly selected in each city every year and the children’s goitrous rate, uric iodine,family salt and water iodine,and health education about IDD,and so on were investigated. Results The goitrous rate of the children aging between 8 and 10 years had a tendency of declining. In 2001,the rate was 6.52%;in 2002,5.84% and in 2003,5.19%. These figures showed the rate was reaching the national index(≤5%). The children’s uric iodine median had been kept between 200 and 300 μg/L for three years. In 2001,was 253.96 μg/L;in 2002,240.30 μg/L and in 2003,265.59 μg/L. 42.8% of the iodine content in the uric samples was greater than 300 μg/L,showing the excessive iodine taking. The edible rate of qualified iodized salt rised steadily-88.0% in 2001,90.0% in 2002,and 94.1% in 2003. The rates of the later two years had reached the national index for eliminating IDD. Conclusions The investigation shows that the three cities in North Shanxi province have achieved the desired results in carrying out the present iodized salt standard to prevent and control IDD. The children’s goitrous rate,uric iodine level and the edible rate of qualified iodized salt all meet the demands of national elimination of IDD. IDD has been controlled effectively.更多还原
