Abstract: Objective To explore the changing trend of iodine nutrition status of children aged 8-10 years in Yun’an District, and to provide an important basis for formulating targeted iodine nutrition intervention strategies for children inYun’an District. Methods The urine iodine content, household salt iodine content and thyroid volume of non-boardingchildren aged 8～10 were randomly selected every year. Results From 2020 to 2024, the median urinary iodine of 1,000children aged 8～10 in Yun’an District was 239.5 μg/L, 3.3% for children under 50 μg/L and 10.5% for children under 100 μg/L, and there were significant differences in urinary iodine levels among different years (H = 37.214, P＜0.05) and between genders (Z＝-2.820，P＜0.05). The consumption rate of qualified iodized salt is 97.4%, and the coverage rate of iodized salt is 100.0%. The goiter rate was 0.8%. Sex has an effect on urinary iodine, and age has an effect on thyroid volume. Conclusion The goal of continuous elimination of iodine deficiency disorders has been achieved in Yun’an District, but some children still have insufficient or excessive iodine intake, which needs continuous monitoring and attention.
