Abstract:
Objective To know the current situation of prevention and control of iodine deficiency disorders in Guangming District of Shenzhen through analyzing related monitoring indicators from 2010-2012.Methods According to the National Iodized Salt Monitoring Program,in Guangming District of Shenzhen,2 Street Offices were chosen,then 4 Neighborhood Committees were chosen in each Street Office randomly,15 household salt samples were selected randomly in each Neighborhood Committee; 5 primary schools were chosen in this district,and 20 urine samples were selected from 8-10 years old children in each school in 2011,one source water and one tap water sample were collected of all the water supply companies in this district in 2012.Salt iodine was determined by direct titration method; urinary iodine was determined by As3--Ce4+ catalytic spectrophotometry method; water iodine was determined by sulfate Ce catalytic spectrophotometry of drinking water standard test method.Results Salt iodine were 27.13 and 21.23 mg/kg in 2010 and 2012,respectively.The rates of qualified iodized salt in 2010 and 2012 were 93.33％ (112/120) and 90.00％ (108/120),respectively.The median concentration of urinary iodine of 8-10 years old children in 2011 was 208.19 μg/L.The median concentration of water iodine in 2012 was 31.60 μg/L.Conclusions The district isn't an iodine excess.The rates of qualified iodized salt in resent years are in line with national standards.There is no iodine deficiency in children and additional supplementation of iodine is not necessary.But relevant monitoring still needs to be improved.
