Abstract:
Objective To analyze the residents' iodine nutrition level of Yunfu City in Guangdong Province from 2009 to 2016,in order to provide evidence for making prevention strategy of iodine deficiency disorders.Methods Four surveys on salt iodine levels,four surveys on urinary iodine levels of children aged 8-10 years old,two surveys on urinary iodine levels of pregnant women and one survey on iodine content in drinking water were carried out according to the prevention and control planning for endemic disease in Guangdong Province in Yunfu City from 2009 to 2016.Salt iodine was determined by direct titration (GB/T 13025.7-1999,GB/T 13025.7-2012),urinary iodine was determined by arsenic cerium catalytic spectrophotometry (WS/T 107-2006,WS/T 107.1-2016),water iodine was determined by the national iodine deficiency disease reference laboratory recommended method.Results In 2009,2011,2015 and 2016,1 464,1 464,1 500,1 500 salt samples and 500,388,1 000,1 000 children were investigated,the medians of salt iodine levels were 30.3,28.1,24.8,and 24.8 mg/kg,respectively,and the medians of children urinary iodine levels were 208.3,188.3,143.1 and 165.2 μg/L,respectively.Five hundred,five hundred pregnant women were investigated in 2015 and 2016,and the medians of pregnant women urinary iodine levels were 101.0 and 96.4 μg/L,respectively.A total of 1 149 samples of drinking water were investigated in 2011-2016,the median of water iodine was 2.8 μg/L.Conclusion Yunfu is an iodine deficiency city,after adjusting the iodine content of edible salt in 2012,iodine nutrition in children is at an appropriate level,but the iodine intake level of pregnant women is relatively lower,so prevention and treatment of iodine deficiency disorders and urinary iodine monitoring should be strengthened in pregnant women.
