RESUMO
O objetivo do estudo foi avaliar a ingestão de iodo em regiões do Estado de São Paulo. 964 escolares foram avaliados e os volumes da glândula tiróide elevaram-se com a idade, guardando correlação positiva com a superfície corporal. 2,9 por cento dos escolares apresentavam bócio e hipoecogenicidade da glândula foi vista em 11,7 por cento da amostra. Houve excessiva excreção urinária de iodo nesta população em 76,8 por cento das amostras. Concluímos que a população de escolares estudados apresenta excessiva ingestão diária de iodo, a qual, poderá induzir várias alterações da função tiroidiana.
ABSTRACT
The objective of this study was to evaluate the iodine nutrition in distinct regions of the state of São Paulo. 964 schoolchildren were examined and there was a progressive increase of the thyroid volume with aging with a positive correlation with the body surface area. The enlarged thyroid gland was present in 2.9 per cent and a few thyroid gland abnormalities were noticed such as hemiagenesia (0.5 per cent), nodules (0.2 per cent), cysts (0.7 per cent) and hypoechogenicity (11.7 per cent). The urinary excretion of iodine was elevated being above 300ug Iodine/L in 76.8 per cent of the schoolchildren examined. We conclude that the schoolchildren population of the State of São Paulo may be under an excessive daily ingestion of iodine. This may induce a subclinical hyperthyroidism in the elderly and possibly an increment in the prevalence of cronic autoimmune thyroiditis.
