Quantitative evaluation of taste in childhood populations: a systematic review

Abstract

IntroductionTaste is of great importance for the feeding process. Seen in this light, it is essential to investigate this sense in children as developing human beings. However, despite little variation in the use of tests that measure the gustatory capacity, there are still questions about the applicability and effective use of tools for quantitative assessment in children. ObjectiveTo search the literature on quantitative instruments used for the evaluation of taste used in studies with children. MethodsA search was conducted in the PUBMED and Web of Science platforms, and subsequently, the identified articles were selected and reviewed. The descriptors and terms used were “taste,” “child,” “assessment,” “diagnosis,” and “dysgeusia”. Original articles related to the theme in English, restricted to children and with no year limitation, were selected. Studies conducted in other stages of human development, exclusively or concurrently with the pediatric population; animal studies; literature review articles; dissertations and book chapters; and case studies and editorials were excluded. The data analysis was performed through a cataloging protocol created for this study, including the following points: author, research department, year, location, population/sample, age, purpose of the study, methods, and primary results. Results5613 items were found. 5307 were excluded based on title, 248 by abstract analysis, and 43 by full text evaluation. Fifteen articles were selected for analysis; of these, six were repeated articles, and thus nine articles were selected for review. ConclusionThe tests aiming at evaluation of taste were judiciously used, ensuring reliability for future research, which may employ methods similar to previous studies.
