ObjectiveTo understand the situation of the intake of iodized salt of the residents in Xuhui District of Shanghai from 2012 to 2015, thereby providing bases for consolidating the achievements of eliminating iodine deficiency disease as well as for formulating the strategies of the control and prevention thereof as a next step.
MethodsEvery year, one community neighborhoods was randomly selected from each of the east, west, south, north and middle parts of Xuhui District, respectively. The content of iodine in edible salt was measured by adopting the direct titrimetric method of GB/T 13025.7—1999(2012 edition) and GB/T 13025.7—2012(2013—2015 edition)；databases were established by utilizing the national monitored information and management system for iodized salt and the SPSS 20.0 software was used to make statistical analyses thereof.
ResultsFor the residents in Xuhui District of Shanghai from 2012 to 2015, both the coverage rate of iodized salt and intake rate of qualified iodized salt decreased gradually and were below 90%. Relevant statistical analyses showed that both the average intake rate of qualified iodized salt and the average iodine content of edible salt of the year of 2015 were significantly lower than the two averages, respectively, of each of the years from 2012 to 2014; that the variation coefficient of iodine content increased gradually; that the coverage rate of iodized salt and the intake rate of qualified iodized salt for the community neighborhoods in CBD districts were generally lower than those for the community neighborhoods in non-CBD districts.
ConclusionThe overall monitoring results of the salt intake of the residents in Xuhui District have failed to meet the relevant national standard for eliminating iodine deficiency disease, so various related departments should strengthen the force of publicity for eliminating iodine deficiency disease.
