This study aimed to evaluate the relative validity of FFQs, in comparison with other methods, in assessing dietary intake of children and adolescents, through a systematic review. Four electronic databases (Embase, PubMed, Scopus and Web of Science) found 67 articles, which met the inclusion criteria (healthy children and adolescents from 3 to 18 years; journal articles written in English, Spanish and Portuguese between 1988 and March 2019; results showing the comparison between the FFQ with other methods of assessment of dietary intake). The articles were analyzed by two independent reviewers. A meta-analysis was conducted using correlation coefficients as estimate effects between the FFQ and the reference standard method. Subgroup analysis and meta-regression were performed to identify the probable source of heterogeneity. In 55 of the 67 studies, a single dietary assessment method was used to evaluate the FFQ; 9 combined the two methods and 3 used three reference methods. The most widely used reference method was the 24-Hour Recall, followed by the Food Record. The overall relative validity of the FFQ to estimate energy, macronutrient, certain micronutrient, and certain food item intakes in children and adolescents may be considered weak.
