[目的]了解重庆市批发层次和居民食用碘盐质量情况,为2010年重庆市消除碘缺乏病提供理论依据。[方法]根据《全国碘盐监测方案》和《重庆市碘盐监测方案》要求进行。[结果]7年来重庆市批发层次碘盐批合格率为96.50%,随时间的增加显著上升(r=0.96,P﹤0.05),碘含量均数(r=0.93,P﹤0.05)和变异系数(r=0.97,P﹤0.05)则呈下降趋势。在2007年居民食用盐的碘盐覆盖率、合格率、合格碘盐食用率均高于90%。2001-2007年居民户碘盐覆盖率(r=0.76,P﹤0.05)、碘盐合格率(r=0.97,P﹤0.05)和合格碘盐食用率(r=0.94,P﹤0.05)逐年显著上升,碘含量均数(r=0.82,P﹤0.05)和非碘盐率(r=0.76,P﹤0.05)则下降明显。[结论]7年来,批发层次和居民食用碘盐质量逐年好转,达到国家消除碘缺乏病阶段目标标准。
[Objective] To understand the quality of iodized salt consumed by wholesale level and residents in Chongqing and provide a theoretical basis for eliminating iodine deficiency deficiency in Chongqing in 2010. [Method] According to the requirements of “National Iodized Salt Surveillance Program” and “Chongqing Iodized Salt Surveillance Program”. [Result] The qualified rate of iodized salt batch in wholesale level of Chongqing was 96.50% over the past 7 years, with a significant increase over time (r = 0.96, P <0.05), mean iodine content (r = 0.97, P <0.05) showed a downward trend. In 2007, the consumption of salt by residents of iodized salt coverage, pass rate, the eligible iodine salt consumption rates were higher than 90%. The iodized salt coverage rate (r = 0.76, P <0.05), iodized salt compliance rate (r = 0.97, P <0.05) and the qualified iodized salt consumption rate (R = 0.82, P <0.05) and non-iodized salt rate (r = 0.76, P <0.05) decreased significantly. [Conclusion] Over the past 7 years, the quality of iodized salt at the wholesale level and residents has been getting better year by year, reaching the national target of eliminating iodine deficiency deficiency stage.
