Abstract:

Objective: To evaluate the potential of indicators of nutritional status of iodine in individuals or populations. Methodology: The review was based on PRISMA. The search for the articles occurred in January 2019, in Pubmed, Scopus and LILACS databases, using the combination indicators AND nutritional status AND iodine. The ion followed the steps of excluding the duplicates, reading the titles, summaries and analyzes in full. The methodological quality of the studies was evaluated by the Downs and Black instrument. Results: 178 studies were identified and 20 were included. Urinary Iodine Concentration (CUI) was analyzed in 65% of the studies and was considered the best indicator to evaluate the nutritional state of the iodine population. Thyroglobulin was determined in 20% of the studies and reflected the pre-existing state of iodine. Thyroid stimulating hormone was verified in 45% of the articles and was sensitive to the surveillance of iodine deficiency in newborns. Only one study evaluated capillary iodine, useful for analyzing long-term dietary intake. In the evaluation of methodological quality, the lowest score was 12 and the highest 16, in 17 possible points. Conclusion: The use of CUI is recommended for the diagnosis of deficiency and excess iodine in the population.
