Abstract
As alterações fisiológicas causadas pela gravidez modificam as necessidades nutricionais e a ingestão alimentar de gestantes. A utilização correta de instrumentos que proporcionem o conhecimento do consumo alimentar no decorrer deste ciclo de vida torna-se relevante por permitir diagnosticar possíveis carências e excessos nutricionais. O objetivo da investigação foi realizar uma revisão bibliográfica sobre métodos de avaliação do consumo alimentar de gestantes. Os estudos analisados foram selecionados em bases eletrônicas de dados e publicados no período de 1994 a setembro de 2004, no Brasil e no exterior. Este artigo procura descrever e analisar os distintos métodos e os principais resultados dos estudos sobre determinação do consumo alimentar de gestantes, entre os quais destacam-se: recordatório de 24 horas (R24h), registro alimentar, questionário de freqüência de consumo alimentar e história alimentar. Os resultados apontam que o R24h foi o método mais freqüente, entretanto, seu uso muitas vezes não ultrapassa dois dias de investigação e nem leva em consideração finais de semana. A preferência por esse método está associada a sua praticidade e custo/benefício. Pode-se concluir que para obtenção de resultados seguros, a escolha do método e do desenho do estudo deve estar sempre relacionada com os objetivos da pesquisa.
Physiological pregnancy changes impact nutritional needs and food intake. The adequate use of tools providing knowledge of food consumption during this life cycle is relevant because it enables the diagnosis for possible nutrition deficits and excesses. The objective of the survey was to perform a bibliographic review on food intake assessment methods during pregnancy. The literature reviewed was selected from an electronic database published between 1994 and September 2004 in Brazil and abroad. This article aims at describing and assessing the different methods and main results of studies determining food intake during pregnancy, among them, the following are highlighted: 24 hour recall, food registration, questionnaire on food intake consumption and food history. The results determine that the 24 hour recall method was the one more frequently used, nevertheless, for many times it was not applied beyond a two day investigation period and it did not take weekends into account. The choice for this method is related to pragmatism and a favorable cost benefit ratio. The conclusion is that to obtain reliable results, the choice of method and study design should always be related to the objectives of the enquiry.
