MACEDO, Mariana de Souza et al. Iodine deficiency and associated factors in infants and preschool children in an urban community in the semiarid region of Minas Gerais State, Brazil, 2008. Cad. Saúde Pública [online]. 2012, vol.28, n.2, pp.346-356. ISSN 0102-311X.  https://doi.org/10.1590/S0102-311X2012000200013.

The aim of this study was to evaluate the prevalence of iodine deficiency in children aged 6 to 71 months in Novo Cruzeiro, Minas Gerais State, Brazil. A total of 475 children, allocated by stratified probability sampling, were analyzed with respect to the iodine concentrations in the salt consumed by the family and urinary iodine. Iodine deficiency was verified in 34.4% of the children, of which 23.5% showed slight deficiency, 5.9% moderate and 5% serious deficiency. A difference in the distribution of iodine deficiency was observed between the urban and the rural environments (p < 0.001) where average urinary iodine concentrations of 150.8 and 114.3µg/L respectively were found. A greater proportion of iodine deficiency was observed among children where the proportion of iodine in the salt consumed was below the recommended level. Although expressive, iodine deficiency in Novo Cruzeiro is not a public health problem according to World Health Organization (WHO), The limitrophe distribution of the urinary iodine associated with low iodine levels in salt suggests that efforts to control this deficiency are not yet complete.
