Food Frequency Questionnaires Validated in Brazil: A Scoping Review.
Article in Journal of human nutrition and dietetics : the official journal of the British Dietetic Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo map food frequency questionnaires (FFQs) validated for the Brazilian population.
methodsThis review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping (PRISMA-ScR) guidelines and the Joanna Briggs Institute (JBI). Studies that validated FFQs specifically for the Brazilian population were included. These instruments assessed the intake of energy, nutrients, foods and food groups. Review articles and studies that did not focus on FFQ validation for Brazil or its populations were excluded. A search of articles published up to June 2025 was conducted in the PubMed/MEDLINE, LILACS, Embase, Web of Science (ISI), Scopus and Google Scholar databases.
resultsA total of 69 articles were identified, dating back to the late 1990s: Southeast (n = 35), South (n = 12), Northeast (n = 10), Central-West (n = 4), North (n = 1) and studies covering two or more regions or populations (n = 7). The FFQs were validated in populations of children and adolescents (n = 18), adults and older adults (n = 36) and women (n = 15). These studies differed in terms of food list size, portion size and the number of frequency categories.
conclusionCompiling and disseminating FFQs validated in Brazil will improve their use in clinical practice and provide a valuable resource for designing future research on food consumption.
