目的及时掌握海南省碘缺乏病病情和人群碘营养状况,评价海南省食用碘盐消除碘缺乏病危害的效果。方法按照卫生部《全国第五次碘缺乏病监测实施意见》的要求,在2005年以居民户碘盐覆盖率、居民户碘盐合格率、合格碘盐食用率,8～10岁学龄儿童甲状腺肿大率、尿碘水平、智商水平、健康教育效果为评价指标。结果共调查1251名8岁～10岁学龄,碘盐食用率67.5%,非碘盐率32.5%,居民户碘盐合格率85.7%,合格碘盐食用率57.7%。甲状腺肿大率触诊法为8.0%,B超法为5.9%,尿碘中位数为92.2Ug/L,平均智商91.7;调查150名育龄妇女,尿碘中位数为71.9Ug/L;健康教育效果评估结果5年级学生组平均分为30.3分;育龄妇女组平均分为53.8分。结论海南省普及碘盐工作有所提高,居民户合格碘盐食用率与国家碘缺乏病消除标准仍有较大差距,海南省碘缺乏病防治工作依然严峻。
Objective To grasp the status of iodine deficiency disorders and iodine nutrition in Hainan Province in time and evaluate the effect of using iodized salt in Hainan Province to eliminate the iodine deficiency disorders. Methods According to the “Opinions on the Implementation of the Fifth National Iodine Deficiency Disease Surveillance” issued by the Ministry of Health, in 2005, the iodized salt coverage rate, the qualified rate of iodized salt in residential households, the eligible iodized salt consumption rate, the thyroid gland of school-age children aged 8 to 10 years Swelling rate, urinary iodine level, IQ level, the effect of health education as the evaluation index. Results A total of 1251 school-age children aged 8 to 10 were enrolled. The iodized salt rate was 67.5% and the non-iodized salt rate was 32.5%. The pass rate of iodized salt was 85.7% and the qualified iodized salt rate was 57.7%. The thyroid goiter rate was 8.0%, the B-ultrasonography was 5.9%, the median urinary iodine was 92.2Ug / L and the average IQ was 91.7. The median of urinary iodine in 150 women of reproductive age was 71.9Ug / L. Results of health education evaluation The 5th grade student group averaged 30.3 points; the average age group of childbearing women was 53.8 points. Conclusion The popularization of iodized salt in Hainan Province has been improved. The consumption rate of qualified iodized salt in residential households still lags behind the standard of elimination of iodine deficiency disorders in China.
