0287/2019 - Análise crítica dos indicadores do estado nutricional de iodo em indivíduos e populações: Uma revisão sistemática. Critical analysis of the indicators of nutritional status of iodine in individuals and populations: A systematic review.
Objetivo: Avaliar as potencialidades dos indicadores do estado nutricional de iodo em indivíduos ou populações. Metodologia: A revisão foi baseada no PRISMA. A busca pelos artigos ocorreu em janeiro de 2019, nas bases Pubmed, Scopus e LILACS, utilizando a combinação indicadores AND estado nutricional AND iodo. A seleção seguiu as etapas de exclusão dos duplicados, leitura dos títulos, resumos e análise na íntegra. A qualidade metodológica dos estudos foi avaliada pelo instrumento de Downs e Black. Resultados: Foram identificados 178 estudos e 20 foram incluídos. A Concentração Urinária de Iodo (CUI) foi analisada em 65% dos estudos e foi considerado o melhor indicador para avaliar o estado nutricional de iodo populacional. A tiroglobulina foi determinada em 20% dos estudos e refletiu o estado de iodo pregresso. O Hormônio Estimulante da Tireoide foi verificado em 45% dos artigos e foi sensível para a vigilância de deficiência de iodo em recém-nascidos. Apenas um estudo avaliou o iodo no cabelo, útil para analisar a ingestão dietética em longo prazo. Na avaliação da qualidade metodológica, a menor pontuação foi 12 e a maior 16, em 17 pontos possíveis. Conclusão: Para diagnóstico de deficiência e excesso de iodo na população recomenda-se a CUI.

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.
