Abstract:
Objective:To analyze the iodine content distribution of drinking water in Jingdezhen City, and master the status of prevention and control of iodine deficiency disorders (IDD), so as to provide a basis for adopting targeted control measures and scientific adjustment of control and prevention strategies.Methods:According to the "National Iodine Deficiency Disorders Surveillance Program" and the "National Water Iodine Content Survey Program for Drinking Water", the surveillance of IDD in Jingdezhen City was carried out from 2017 to 2020. Household edible salt samples from pregnant women and students aged 8 to 10 were collected to detect salt iodine content, and urine samples were collected to detect urinary iodine. Thyroid volume of students was measured by B-ultrasonography, and the rate of goiter was calculated. In 2017, the iodine content of drinking water in Jingdezhen City was investigated, and the results were analyzed.Results:From 2017 to 2020, a total of 1 800 students were examined for thyroid gland, and 11 students were found to have goiter, with an goiter rate of 0.61%. A total of 3 201 edible salt samples and 3 201 urine samples were collected from students, the median of salt iodine was 24.96-26.40 mg/kg, the consumption rate of qualified iodized salt was 98.50%-99.50%, and the median of urinary iodine was 172.56-218.35 μg/L. A total of 1 600 edible salt samples and 1 600 urine samples were collected from pregnant women, the median of salt iodine was 24.40-25.38 mg/kg, the consumption rate of qualified iodized salt was 97.25%-98.00%, and the median of urinary iodine was 161.55-205.60 μg/L. In 2017, a total of 667 water samples were collected from 52 villages and towns in 4 counties and districts. The median of water iodine of the 4 counties and districts was 0.6-3.2 μg/L, and that of the 52 villages and towns was 0.3-12.3 μg/L.Conclusions:The iodine nutrition level of students and pregnant women in Jingdezhen City is generally at an appropriate level, but the iodine content of drinking water is low. It is suggested to strengthen the health education and health promotion of IDD among key population, guide the residents to supplement iodine scientifically, and continuously eliminate the harm of IDD.
