新疆1997年县(市)级碘盐监测分析

Analysis of iodized salt monitoring at county levels of Xinjiang in 1997

目的为及时准确地掌握新疆１９９７年食用碘盐防治碘缺乏病的现况，并为全面评估防治效果和制定防治决策奠定基础。方法采用逐级汇总上报的方法；首先由各地在规定时间内依照批质量保障抽样法（ＬＡＱＳ）在加碘企业、零售店、居民户进行抽样，统一采用定量滴定法检测，结果汇总后逐级上报。结果新疆１９９７年县、市级共检测盐样９４１批，其中合格７８２批（８３．１０％）；各抽检点的合格率分别为加碘企业（８３．４６％）、零售点（９１．５６％）、居民户（７１．３８％），不同抽检层次间批合格率有显著差异（Ｐ＜０．０１）。结论新疆碘盐合格率虽较１９９６年有了长足的进展，但距消除碘缺乏病的标准还有差距。

Objective In order to know well the current status of iodized salt for IDD control in Xinjiang in 1997 and lay the groundwork for assessing overall protecting effect and working out a plan.Methods The method for submitting the collected data to the leadship was used step by step.According to LQAS,sampling at salt making factories,shops,inhabitant was conducted in all counties within the fixed time.Quantified titration was used unifiedly.Results Nine hundred and fourty one lots were detected in every area of Xinjiang in 1997,83.10% of them (782) lots being qualified.There was different qualified rate at every site,the iodized salt making factories (83.46%),shops (91.56%),inhabitants (71.38%).The difference was very significant ( P <0.01).Conclusion Although the iodized salt qualified rate was much raised in 1997 compared to 1996,there was a distance from the elimination.Especially qualified rate at inhabitants should be paid more attention to improve.
