AI Article Synopsis
- The study aimed to assess how universal salt iodization affects iodine deficiency and thyroid diseases based on hospital data.
- Data showed that over 95% of the population had access to adequately iodized salt, but hospitalization rates for thyroid diseases increased significantly, especially among women over 40.
- Despite rising thyroid disease hospitalizations, the overall positive impact of universal salt iodization in reducing iodine deficiency is considered to outweigh the negative effects.
Article Abstract
Objective: To evaluate the impact of universal salt iodization using monitoring data on correctional status of iodine deficiency and hospitalized thyroid diseases.
Methods: Retrospective survey was conducted to collect medical records of hospitalized thyroid disease cases. Routine monitoring data on population iodine nutrition status and goiter prevalence were analyzed.
Results: The coverage of adequately iodized salt was consistently above 95%. Hospitalization rate of thyroid diseases rose steadily, and peaked at 54.5 per 100,000. The proportion of hospitalized thyroid disease among hospitalized diseases also rose with female and those aged above 40 years old mostly affected. The proportion of hospitalized hyperthyroidism among total hospitalized thyroid disease rose from 13.6% to 34.7%.
Conclusions: Universal salt iodization might eliminate iodine deficiency while other impact still exists. However, the benefits of universal salt iodization should be far overweight the adverse effects.
