Abstract(s)
Para eliminar a deficiência em iodo, observada em Portugal, em crianças
em idade escolar, a Direção-Geral da Educação emitiu uma circular
que orienta as escolas para confecionarem as refeições utilizando sal
iodado. Este trabalho teve como objetivo a monitorização, e avaliação,
da aplicação desta circular nas escolas de primeiro ciclo da área metropolitana
de Lisboa. Foram analisadas refeições escolares que abrangem
cerca de 3000 crianças, num total de 300 alimentos recolhidos. Para a
determinação do conteúdo de iodo nas amostras analisadas recorreu-se
à espectrometria de massa com plasma indutivo acoplado (ICP-MS).
A escola-piloto, utilizada como referência, apresentou, na maioria das
amostras, um conteúdo de iodo mais elevado quando comparado com as
amostras do conjunto de todas as escolas. As refeições confecionadas
no Instituto Nacional de Saúde Doutor Ricardo Jorge, e utilizadas como
baseline, foram, como seria de esperar, aquelas onde o conteúdo de
iodo apresentou os valores mais baixos. A determinação de iodo, em
paralelo com a de sódio, leva-nos a crer que apenas a escola referência
confeciona as suas refeições exclusivamente com recurso ao sal iodado.
To combat iodine deficiency in Portuguese schoolchildren the Directorate- General for Education issued a circular that obliges schools to prepare meals using iodized salt. The objective of this work was to monitor, and evaluate, the application of this circular to primary schools from the metropolitan area of Lisbon. A total of 300 foods collected from meals served in school canteens, covering about 3000 children, were analyzed. For the determination of the iodine content in the analyzed samples we used inductively coupled plasma mass spectrometry (ICP-MS). The school used as reference showed a higher iodine content, in the majority of the samples, when compared to the other schools. The meals prepared in the National Institute of Health Doutor Ricardo Jorge, and used as baseline, were, as expected, the meals with the lowest iodine content. The determination of iodine, in parallel with sodium, leads us to believe that only the reference school prepares its meals exclusively with iodized salt.
