摘要目的 综合分析张家口市2001-2009年度碘盐监测数据,为制订碘缺乏病防治策略提供依据.方法 按照卫生部<全国碘缺乏病监测方案>碘盐监测的要求,在张家口市17个县(区)中.各县区每月对本辖区内碘盐加工(批发)企业抽取1批9份盐样;每县(区)每年度按东、南、西、北方位各抽取2个乡(镇、街道办事处),中区抽取1个乡(镇、街道办事处),每乡(镇、街道办事处)抽取4个村(居委会),每村(居委会)抽取8份户盐,采用直接滴定法定量测定含碘量.结果 碘盐加工(批发)企业:2001-2009年全市共监测1728批次,合格1689批次,批质量合格率为97.74%;检测盐样15 552份,合格15 357份,碘盐合格率为98.75%.居民户:2001-2009年全市共监测1305个乡(镇、街道办事处),5297个村(居委会);采集盐样44 316份,其中合格43274份,碘盐合格率为98.04%(43 274/44 141),碘盐覆盖率为99.61%(44 141/44 316),合格碘盐食用率为97.65%(43 274/44 316),非碘盐率为0.40%(260/44 316),盐碘中位数为30.02 mg/kg.结论 9年中张家口市各项碘盐质量指标均位于国家控制指标以内,且保持在相对较为稳定的水平,各年度波动范围较小.非碘盐历年都有检出,成为影响碘缺乏病防治效果的主要因素,应加大监测、监督力度,普及健康教育知识.遏止非碘盐的泛滥.

abstractsObjective To analyze comprehensively the monitoring data of iodized salt in Zhangjiakou city during 2001 to 2009, and to provide basic information for working out control strategies of the iodine deficiency disorders. Methods According to the iodized salt monitoring requirements in "National Iodine Deficiency Disorders Monitoring Program" of Ministry of Health, a batch of nine salt samples were taken from each processing (wholesale)company of each county or district of the seventeen counties(districts) of Zhangjiakou once a month. Two townships (towns, street offices) were selected by their location of east, south, west and north in each county(district), and a township in central area each year. Four villages(neighborhoods) were selected in each township(town, street office),and eight household salt samples were collected in each village(neighborhood), and quantitatively determined by direct titration of iodine. Results Iodized salt processing(wholesale) : during 2001 to 2009, a total of 1728 batches was monitored, 1689 batch qualified, batch qualification rate 97.74%;15552 salt samples were tested, 15 357 qualified, iodized salt qualification rate 98.75 %. Household salt levels : 5297 villages (neighborhoods) of 1305 townships(towns, street offices) were monitored, 44 316 salt samples were collected, 43 274 qualified, iodized salt qualification rate 98.04%(43 274/44 141 ), iodized salt coverage rate 99.61%(44 141/44 316), qualified iodized salt consumption rate 97.65%(43 274/44 316). Rate of non-iodized salt was 0.40%(260/44 316), and salt median iodine was 30.02 mg/kg. Conclusions The iodized salt quality indicators are within the state-controlled range in Zhangjiakou city for nine years which remaines at relatively stable levels with a smaller range of annual fluctuations.Detection of non-iodized salt over the years has become the main factors affecting the effectiveness of the prevention and control measures.We should increase monitoring,supervision,and universal health education,and prevent the spread of non-iodized salt.
