Abstract:
Objective To investigate the iodine nutritional status among children aged 8-10 years old in Henan Province after five years of implementation of new standard iodized salt,and to provide evidence for scientific adjustment of control strategy.Methods In 2017,according to "Henan Surveillance Program on Iodine Deficiency Disorders",children aged 8-10 years old (half males and half females) were chosen as research targets.In nonhigh iodine areas of 156 non-high iodine counties (cities,districts) and high iodine counties (cities,districts) in Henan Province,household salt samples were collected;in 113 counties (cities,districts),urine samples were collected;in 67 counties (cities,districts),thyroid volume was measured.Salt iodine was tested by direction titration,the salt samples from Sichuan and other enhanced salt samples were tested by the arbitration method;urinary iodine was tested by arsenic cerium catalytic spectrophometry;thyroid volume was measured by ultrasound method.Results In 2017,totally 31 174 household salt samples of 8-10 years old children were collected and tested,the median of salt iodine was 25.8 mg/kg;the coverage rate of iodized salt was 95.0％ (29 613/31 174) and the consumption rate of qualified iodized salt was 85.6％ (26 673/31 174).Totally 22 442 urine samples were collected and the median of urinary iodine content was 208.0 μg/L.Totally 13 439 school children were examined thyroid volume and the goiter rate.was 1.5％ (196/13 439).Conclusions After the promotion of new standard iodized salt,the iodine nutritional status of children aged 8-10 years old in Henan Province is appropriate.However,the consumption rate of qualified iodized salt is lower,so the universal salt iodization prevention and control strategies should be performed for a long time.At the same time,health education of iodine deficiency knowledge should be strengthened.
