摘要
目的探讨2004—2010年保山市居民户食用盐中碘含量的长期变化趋势,为适时采取有针对性地防治措施和科学调整干预策略提供参考。方法依据《全国碘盐监测方案》,利用2004—2010年碘盐监测、检测资料,分析全市居民户食用盐中居民合格碘盐食用率、碘盐合格率、非碘盐率及其变化趋势。结果 7年来全市共采集了10090份居民户食用盐,其中检出碘盐9997份(居民户合格碘盐食用率为97.06%,碘盐合格率为97.96%),非碘盐93份(非碘盐率为0.92%);居民户合格碘盐食用率2005—2010年均高于2004年,但自2005年之后开始呈下降趋势;2004—2010年碘盐合格率在95.82%～98.16%之间波动,保持相对稳定。总体上看居民户合格碘盐食用率、碘盐合格率均在90%以上。非碘盐率2005—2009年各年均低于2004年水平(1.88%),2005—2007年非碘盐率均低于0.5%,2007年之后逐年上升,在2010年非碘盐率达2.15%。以2004年为参照,2005—2010年居民户合格碘盐食用率、碘盐合格率、非碘盐率与之比较,各年的差异均具有统计学意义(P<0.01)。结论居民户合格碘盐食用率及碘盐合格率总体上达到了国家标准,但仍然存在不稳定现象,特别是非碘盐率呈先下降后上升的波动趋势,因此,应在常规监测的基础上,及时发现问题所在,加强食盐生产、流通和上市的监督管理,遏制不法渠道流通非碘盐,净化盐业市场。
OBJECTIVE To explore the long-term change trend of iodine content on edible salt in Baoshan Prefecture resident and adopt effectively the preventing measures in a proper manner, and furthermore provide scientific reference for preventing iodine deficiency disorders METHODS Based on the surveillance regimen of national iodized salt, using the surveillance data between 2004 and 2010 to analyze the rate of eating qualified iodized salt, the rate of qualified iodized salt and the rate of non-iodized salt, and variation tendency. RESULTS A total of 10 090 samples was collected during 7 years, including the iodized salt 9 997samples （the rate of eating qualified iodized salt was 97.06%, the rate of qualified iodized salt was 97.96%） , non-iodized salt was 93 samples （the rate of non- iodized salt was 0.92%）; the rate of eating qualified iodized salt between 2005 and 2010 was higher than that of 2004, however, after 2005 the rate gradually decreased; the rate of qualified iodized salt which was range from 95.82% to 98.16% maintained relatively constant in study period. Overall, both the rate of eating qualified iodized salt and the rate of qualified iodized salt were above 90%. The rate of non-iodized salt between 2005 and 2009 were lower than that（1.88%） of 2004, and lower than 0.5% among 2005, 2006, 2007, after 2007 it has gradually increased, and reached 2.15% in 2010. Based on abovementioned three indicators in 2004 as the benchmark which was respectively compared to the counterparts of the rest of years was significant（P〈0.01）. CONCLUSION Overall, the rate of eating qualified iodized salt, the rate of qualified iodized salt, and the rate of non-iodized salt reached the national standards, however, three indicators are not stable, especially the rate of non-iodized salt first decreased and then increased with fluctuation, therefore based on routine monitoring to find the crux, furthermore, strengthen the production, intermediate, listing of supervision and management of salt, stop the circulation o
