Índices dietéticos na avaliação da qualidade global da dieta

Abstract

A alimentação pode atuar tanto na prevenção de certas doenças como no tratamento de outras. A análise do consumo alimentar fornece subsídios para avaliação das necessidades nutricionais e para promoção de programas de educação nutricional. Poucos estudos têm sido realizados com o objetivo de se fazer a avaliação global da dieta. Os índices dietéticos estão sendo estudados como uma alternativa para realizar esta avaliação.Este trabalho tem por objetivo apresentar os seguintes índices dietéticos: Índice de Nutrientes, Escore de Variedade da Dieta, Escore de Diversidade da Dieta, Índice de Qualidade da Dieta, Índice de Alimentação Saudável e Índice de Qualidade da Dieta Revisado. Observou-se que os índices possuem fundamental importância ao refletir a situação de diversos componentes da dieta em uma única variável.Termos de indexação: avaliação nutricional, consumo de alimentos, saúde pública, dieta, nutrição. A B S T R A C T Feeding can act in the prevention of some diseases as well as in the treatment of others. The analysis of food consumption provides information to assess nutritional needs and improve nutrition education programs.

Qualidade da dieta de adolescentes: estudo de base populacional em Campinas, SP

“…These dietary inadequacies become even more relevant as a result of the high prevalence of overweight and obesity among adolescents 6 . When considering the repercussions of diet on the general state of health and the incidence of disease, researchers have sought to develop indices to evaluate quality of diet in a global and synthetic form 7 . The Healthy Eating Index -(HEI), which represents such an index, was developed by the Department of Agriculture of the United States, with the aim of evaluating nutritional care needs and the recommendations of dietary guidelines 8 .…”

Aspectos metodológicos da avaliação da qualidade da dieta no Brasil: revisão sistemática

“…The IQD also considers protein intake rather than simply foods containing protein; it evalu- ates the intake of fruits and vegetables as a single item, as well as the intake of cereals and legumes; it does not consider alcohol intake and it assigns a higher score to a lower quality diet [57][58][59][60] . Another important consideration is that the revised IQD, which was proposed by Haines et al 58 , contained different characteristics from the HEI, such as proportionality between food groups, the evaluation of the intake of specific micronutrients (calcium and iron) and the absence of the food components of milk its derivatives, and protein foods 59,60 . Therefore, naming dietary quality instruments that were adapted from the HEI as IQD or revised-IQD is inappropriate since these instruments contain different items and recommendations.…”

“…28 Other authors describe how, although limitations exist, the indexes manage to assess overall diet, characterizing dietary patterns, in contrast to the analysis of nutrients in isolation. 4,7,17,18 Another limitation of the study was using the FFQ as an assessment method of dietary consumption, as it contains a limited number of foods in comparison with dietary history. 28 Moreover, as it is a semi-quantitative questionnaire, the FFQ used may have contributed to overestimating the quantities of each of the investigated food items consumed.…”
