Summary

Current Chinese dietary iodine reference intake (DRIs) standards lack direct data on recommended iodine intake (RNI) in the elderly. The elderly have a high prevalence of thyroid diseases. The risk threshold of iodine intake in the elderly is unknown. Identifying the appropriate iodine intake for the elderly to maintain optimal thyroid function to reduce the burden on medical resources is a public health issue requiring high attention. The iodine balance study is an important method for exploring physiological iodine requirements. Few iodine balance studies have been conducted in the elderly. This study aimed to conduct an iodine balance study and provide information on the appropriate iodine intake level for elderly people.
