Abstract

Abstract

Objective To explore the iodine nutritional status of children aged 8-10 in Luzhou from 2018 to 2022, and to provide a basis for evaluating the effectiveness of iodine deficiency disorders prevention and adjusting iodine supplementation strategies. Methods A stratified cluster random sampling was adopted from 2018 to 2022, randomly selecting 7 000 children aged 8 to 10 from seven counties (districts) in Luzhou City. Urine samples and frequently consumed salt samples were collected and tested according to relevant standards. Excel 2019 and SPSS 25.0 were used for descriptive analysis to calculate indicators such as the median urinary iodine, median salt iodine, iodized salt coverage rate, iodized salt qualification rate, and the consumption rate of qualified iodized salt. The iodine nutrition status of Luzhou residents was evaluated through methods such as the Kruskal-Wallis H test and chi-square test. Results The median of urinary iodine was 184.1(124.7, 255.0) μg/L. There was a statistically significant difference in urinary iodine concentration among children in different years and counties (districts) (P < 0.001). The difference in it among children aged 8, 9 and 10 years old was also statistically significant (χ² =12.251, P=0.002). The urinary iodine concentration of boys was higher than that of girls (Z=-4.433, P < 0.001). The median salt iodine of 7 000 salt samples was 26.6(24.5, 28.8) mg/kg, the coverage rate of iodized salt was 99.27%, the qualified rate of iodized salt was 94.88%, and the edible rate of qualified iodized salt was 94.19%. The differences in salt iodine content, coverage rate of iodized salt, and edible rate of qualified iodized salt were statistically significant in different years and counties (districts) (all P < 0.05). Conclusions From 2018 to 2022, the overall iodine nutrition of children aged 8-10 is suitable in Luzhou, and the consumption of iodized salt is good, meeting the elimination standards for iodine deficiency disorders. However, there is still a certain proportion of children with iodine malnutrition. In the future, efforts should continue to be made to monitor iodine nutritional status and promote the publicity and education of reasonable iodine nutrition.
