Abstract:
Objective:To study the iodine nutrition status of key populations in Sichuan Province, so as to provide a basis for scientific supplementation of iodine and adjustment of prevention and control measures.Methods:From 2018 to 2022, the stratified cluster sampling method was used in 21 counties (district) in Sichuan Province. Each county (district) was divided into 5 areas based on east, west, south, north, and center. One township (street) was selected as a monitoring site from each area. Forty children aged 8 - 10 years old and 20 pregnant women, women of childbearing age, lactating women, and their infants and young children (0 - 2 years old) were randomly selected from each monitoring site. Household edible salt and urine samples were collected for salt and urine iodine testing. B-ultrasound method was used for thyroid examination in children.Results:A total of 52 019 samples of edible salt were collected, including 50 084 qualified iodized salt samples. The qualified iodized salt consumption rate was 96.3%, and the median salt iodine was 27.1 mg/kg. A total of 21 021 urine samples from children were tested, with a median urine iodine level of 199.5 μg/L. A total of 10 293 urine samples were taken from pregnant women, and the median urine iodine level was 172.6 μg/L. A total of 10 502 urine samples were taken from women of childbearing age, with a median urine iodine level of 174.4 μg/L. A total of 10 444 urine samples were taken from lactating women, and the median urine iodine level was 164.9 μg/L. There were 10 442 urine samples from infants and young children, and the median urine iodine level was 191.9 μg/L. A total of 21 028 children underwent thyroid examination, with a goiter rate of 1.8% (370/21 028).Conclusion:From 2018 to 2022, the iodine nutrition of key populations in Sichuan Province is at an appropriate level, and the elimination of iodine deficiency disorders continues to be maintained.
