ABSTRACT

Objective To get to know the status of iodine deficiency disorders (IDD) and provide scientific basis for the 13th Five-year Plan of control and prevention of IDD in Hubei Province.Method In 2015,103 counties were selected to test or inspect iodine content of 300 salt samples from 300 residents,urinary iodine content and thyroid volume (palpation) of 200 children aged 8-10,and urinary iodine content of 100 pregnant women.Results Thirty thousand and nine hundred salt samples were collected.Coverage rate of iodized salt,qualified rate of iodine salt and qualified iodine salt edible rate were 99.61％ (30 780/30 900),94.46％ (29 074/30 780) and 94.09％ (29 074/30 900),respectively;the median iodine content of 20 600 urine samples of 8-10 old children was 252.0 μg/L and goiter rate was 0.39％ (80/20 600);the median iodine content of 10 257 urine samples of pregnant women was 180.0 μg/L.Conclusions As a whole,the measure of control and prevention of IDD by iodized salt is implemented well in Hubei Province.The overall iodine nutrition of residents is good.However there is space to lower the iodine concentration of iodized salt with coordinated measure of special edible salt for pregnant woman to satisfy different needs of special people.
