ObjectiveTo investigate the iodine nutrition status of children under 8-10 years old in Erqi District of Zhengzhou City from 2017 to 2020, and to analyze the correlation between iodine nutrition status and salt iodine.MethodsA total of 800 children under 8-10 years old were selected from 9 communities in Erqi District of Zhengzhou City by stratified sampling method, and their urine iodine, salt iodine and thyroid were detected. The salt iodine content, urine iodine content and qualified rate of salt iodine in different years were analyzed, and the correlation between urine iodine and salt iodine was analyzed by Spearman rank correlation.ResultsThe overall median of salt iodine concentration was 26.2 mg/kg, and the total qualified rate of salt iodine was 93.00% (744/800); there were significant differences in salt iodine content and qualified rate among different years (P0.05); the incidence of goiter was low (2.88%), and there was no significant difference among different years (P>0.05).ConclusionFrom 2017 to 2020, the iodine nutrition status of children under 8-10 years old in Erqi District of Zhengzhou City was mostly at the appropriate level, and the salt was basically qualified iodized salt.
