ABSTRACT
ObjectiveTo master iodized salt monitoring results in Zhangjiakou city Hebei province,search problems in these monitoring results,and provide a basis for the development of control measures to iodine deficiency disorders.MethodsBy 2010,in Zhangjiakou city,nine salt samples were collected to detect the iodine level in each processing,packing and wholesale enterprise according to their orientation of east,west,north,south and center positions.In each county(district) with nine townships(towns,street offices) and more,nine townships (towns,street offices) were selected according to their east,west,south,north and center positions,in each township (town,street office ) selected,four villages (neighborhoods) were selected,eight residents per household in each village (neighborhood) chosen were selected,and an edible salt was collected in each household to test iodine level; in a county(district) with nine or less townships(towns,street offices),five townships(towns,district offices) were selected according to their east,west,south,north and center positions,four villages (neighborhoods) were selected,and 15 residents per household in each village(neighborhood) were selected to test the iodine level in an edible salt samples;after population-weighted calculation,indicators of iodized salt monitoring were calculated.ResultsA batch quality pass rate of processing,packing and wholesale enterprise was 100％(192/192); the rate of weighted non-iodized salt in a household was 0.04％(2/4932),iodized salt coverage rate was 99.96％ (4930/4932),iodized salt passing rate was 99.55％ (4908/4930),and qualified iodized salt coverage rate was 99.51％ (4908/4932).ConclusionsMonitoring indicators of iodized salt in Zhangjiakou city have reached the standand to eliminate iodine deficiency disorders.However,there still have unqualified iodized salt and non-iodized salt,and the monitoring and iodized salt market management should be strengthened.
