Abstract:
Objective To understand the coverage of iodized salt and the iodine nutritional status of schoolchildren in Hongkou District of Shanghai City and to provide a basis for adjusting corresponding intervention measures.Methods From 2012 to 2016,according to the "Shanghai Iodine Deficiency Disease Surveillance Program",a street was chosen from five directions as east,west,south,north and centre in Hongkou District.According to the annual monitoring plan,a certain amount of residents or schoolchildren aged 8-10 were chosen for monitoring,collecting salt samples from residents or children's home to detect salt iodine,and collecting urine samples of children to detect urinary iodine level (which was not tested in 2013).Determination of iodine salt was based on "Determination of Iodine by the General Test Method for the Salt Industry" (GB/T 13025.7-2012),urinary iodine determination was based on "Arsenic and Cerium Catalytic Spectrophotometric Determination of Iodine in Urine" (WS/T 107-2006).Results From 2012 to 2016,a total of 1 550 edible salt samples were tested,including 847 qualified iodized salts,299 unqualified iodized salts and 404 non-iodized salts,the coverage of iodized salt was 73.9％,and the consumption rate of qualified iodized salt was 54.6％.A total of 591 urine samples were tested in 2012,2014-2016.The median of urinary iodine was 177.2 μg/L;of which ＜ 100 μg/L was 103,accounting for 17.4％;100-199 μg/L was 248,accounting for 42.0％;and ≥300 μg/L was 91,accounting for 15.4％.Conclusions The residents in Hongkou District of Shanghai City do not meet the target of iodized salt coverage and consumption rates of qualified iodized salt.The average urinary iodine level of schoolchildren aged 8-10 years has reached the national standard for eliminating iodine deficiency disorders;we should further improve the consumption rate of qualified iodized salt.
