目的了解广州市海珠区居民户食用碘盐情况,为完善持续消除碘缺乏病工作提供科学依据。方法按《全国碘缺乏病碘盐监测方案》,每年抽取9个监测点,每监测点抽取32户居民户,2002-2011年10年间共采集2 880份居民户食用盐,采用GB/T13025.7-1999直接滴定法对采集的食用盐进行含碘量检测,并开展碘缺乏病防治知识知晓率调查。结果海珠区近10年居民户的碘盐覆盖率为97.29%,合格碘盐食用率为94.93%;各年度的居民碘盐覆盖率、合格碘盐食用率均达到90%以上,但盐碘的变异系数、非碘盐频数较高;居民碘缺乏病防治知识知晓率较低。结论广州市海珠区连续10年居民碘盐覆盖率、合格碘盐食用率符合达到国家消除碘缺乏病标准,但需继续加大碘盐监管力度,提高碘盐含碘量均匀度,打击私盐,进一步加强健康教育工作,确保居民正确食用合格碘盐。
Objective To understand the situation of iodized salt consumed by residents in Haizhu District of Guangzhou City and to provide a scientific basis for improving the work of eliminating iodine deficiency disorders. Methods According to “National iodine deficiency disease iodized salt monitoring program”, 9 monitoring points were drawn per year and 32 households were selected for each monitoring point. A total of 2 880 household salt samples were collected during 2002-2011 using GB / T13025. 7-1999 direct titration method for the detection of iodine content of the collected edible salt, and to carry out knowledge of iodine deficiency disease prevention and control awareness survey. Results In the recent 10 years, the iodized salt coverage rate of residents in Haizhu District was 97.29% and that of qualified iodized salt was 94.93%. The iodized salt coverage rate and the qualified iodized salt consumption rate of residents reached over 90% in each year, but salt iodine Coefficient of variation, high frequency of non-iodized salt; awareness of iodine deficiency prevention and control of residents is low. Conclusion The iodine salt coverage rate and the qualified iodized salt consumption rate of residents in Haizhu District of Guangzhou City for 10 consecutive years are in line with the national standards for eliminating iodine deficiency disorders. However, the monitoring of iodized salt should be stepped up, the uniformity of iodine salt content should be increased, , To further strengthen health education to ensure that residents have the proper consumption of qualified iodized salt.
