0165/2015 - Metodologias De Identificação De Padrões Alimentares A Posteriori Em Crianças Brasileiras: Revisão Sistemática Methods of identification of food patterns a posteriori in brazilian children: systematic review
O objetivo deste estudo é fornecer orientações para identificação de padrões alimentares por abordagem a posteriori, bem como analisar os aspectos metodológicos dos estudos realizados no Brasil que identificaram padrões alimentares de crianças.Os artigos foram selecionados nas bases de dados da Literatura Latino-Americana e do Caribe em Ciências da Saúde, Scientific pattern; Principal component analysis; Factor analysis; Cluster analysis; Reduced rank regression. Incluíram-se pesquisas que identificaram padrões alimentares de crianças por meio da abordagem a posteriori. Selecionou-se 7 estudos, sendo 6 transversais e 1 de coorte, publicados entre 2007 e 2014. Cinco usaram como inquérito alimentar o questionário de frequência alimentar, um o recordatório de 24h e outro uma lista de alimentos. O método de abordagem exploratória mais utilizado nas publicações foi a análise fatorial por componentes principais, seguida da análise de agrupamento. O tamanho amostral dos estudos variou de 232 a 4231, os valores do teste Kaiser-Meyer-Olkin de 0,524 a 0,873, e o alfa de Cronbach de 0,51 a 0,69. Poucos estudos brasileiros identificaram padrões alimentares de crianças utilizando abordagem a posteriori, e a análise fatorial por componentes principais foi a técnica mais usada.

Abstract:
The objective of this study is to provide guidance for identifying dietary patterns by a posteriori approach, and analyze the methodological aspects of the studies conducted in Brazil that assessed dietary patterns of children. Articles were selected in the databases of the Latin American and Caribbean Literature on Health Sciences, Scientific Electronic Library Online and Pubmed. The descriptors were: Dietary pattern; Food pattern; Principal Component Analysis; Factor analysis; Cluster analysis; Reduced rank regression. We included studies who identified dietary patterns of children through a posteriori approach. We selected seven studies, with six cross-sectional and one of cohort, published between 2007 and 2014. Five used as methods dietary assessment the food frequency questionnaire, one a 24-hour dietary recalls and other a list of foods. The method of exploratory approach used in most publications was the principal component factor analysis (6 studies), followed by cluster analysis (1 study). Few brazilian studies identified dietary patterns of children using a posteriori approach and factor analysis of principal components was the most used technique.
