ABSTRACT
Objective:To investigate the status of iodine deficiency disorders in children and pregnant women in Ganzhou City, Jiangxi Province, and to provide a basis for scientific iodine supplementation and adjustment of prevention and control strategies.Methods:According to the requirements of the National Iodine Deficiency Disorders Surveillance Program (2016 Edition), iodine deficiency disorders surveillance was carried out in 18 counties (cities, districts) under the jurisdiction of Ganzhou City from 2018 to 2022. Edible salt and urine samples taken from children aged 8 to 10 and pregnant women were collected to detect salt and urine iodine levels. At the same time, B-ultrasound method was adopted to measure children's thyroid volume, and the goiter rate was calculated.Results:From 2018 to 2022, a total of 27 075 edible salt samples were collected from key populations (children aged 8 - 10 and pregnant women), with a median salt iodine of 25.00 mg/kg and a qualified iodized salt consumption rate of 96.24% (26 057/27 075). The difference in the qualified iodized salt consumption rate among key populations in different years was statistically significant (χ 2 = 29.09, P < 0.001). A total of 18 061 urine samples were collected from children, with a median urine iodine of 192.10 μg/L, there was a statistically significant difference in the urine iodine level of children between different years ( H = 82.59, P < 0.001). A total of 9 014 urine samples were collected from pregnant women, with a median urine iodine of 177.20 μg/L, there was a statistically significant difference in urine iodine level of pregnant women between different years ( H = 78.78, P < 0.001). A total of 8 621 children's thyroid glands were examined, including 34 cases of goiter, with a goiter rate of 0.39%, and the goiter rate showed a decreasing trend year by year (χ 2trend = 11.09, P < 0.001). Conclusions:From 2018 to 2022, the iodine nutrition of children and pregnant women in Ganzhou City is at an appropriate level, the consumption rate of qualified iodized salt (> 90%) and the children's goiter rate (< 5%) met the national iodine deficiency disorders elimination standards. Ganzhou City continues to maintain the status of eliminating iodine deficiency disorders.
