Iodized salt serves as an effective intervention strategy, combating iodine deficiency disorders (IDD) and promoting overall health. This study aimed to assess the household salt consumption status and its relationship with urinary iodine (UI) levels among school-aged children. This is a descriptive-cross-sectional study that was selected by cluster-random sampling from 5 girls' schools (182) and 5 boys' schools (169), with a total of 351 primary school students (8-10 years old) of Darab. To explore the relationship between independent variables and dependent variable, urinary iodine (UI) levels, linear regression model was applied. A significance level of 0.05 was adopted for all analyses. The median UI level was 138 µg/L (IQR = 111). Our findings revealed that 66% of used iodized salt. A significant majority of participants properly stored their salt in containers with lids. Nearly half of the students in Darab have insufficient iodine intake. Despite controlling for the effect of iodized foods consumption, no significant association (P-value = 0.693) was observed between the storage method and iodized foods. Our study showed that students do not receive enough iodine or have received more than the required amount of iodine. Therefore, efforts should be focused on increasing awareness of diseases caused by iodine deficiency.
碘盐是一种有效的干预策略，可防治碘缺乏病（IDD）并促进整体健康。本研究旨在评估学龄儿童家庭用盐消费状况及其与尿碘（UI）水平的关系。这是一项描述性的横断面研究，采用整群随机抽样法，从德拉布的 5 所女子学校（182 人）和 5 所男子学校（169 人）中抽取 351 名 8-10 岁的小学生。为了探讨自变量与因变量尿碘（UI）水平之间的关系，采用线性回归模型进行分析。所有分析均采用 0.05 的显著性水平。尿碘中位数为 138µg/L（IQR=111）。研究结果表明，66%的家庭使用的是加碘盐。大部分参与者将盐妥善存放在带盖子的容器中。德拉布近一半的学生碘摄入量不足。尽管控制了食用碘盐的影响，但储存方法与碘盐之间不存在显著关联（P 值=0.693）。研究表明，学生没有摄入足够的碘，或者摄入的碘超过了所需的量。因此，应重点提高对碘缺乏病的认识。
