Identifying and Mapping Canadian Registered Dietitians’ Perceptions and Knowledge of and Experiences with Weight-Related Evidence: A Scoping Review

Publication: Canadian Journal of Dietetic Practice and Research
7 January 2025

Abstract

In this scoping review, “weight-related evidence” is an umbrella for various terms, phrases, and ways in which weight, body size, fatness, and/or obesity present in research and dietetic practice. Canadian Registered Dietitians’ perceptions of, experiences with, and/or knowledge of weight-related evidence in nutrition care was identified and mapped. Implementing JBI scoping review methodology, four databases were searched: (i) CINAHL (EBSCO); (ii) Medline (Ovid); (iii) Embase (Elsevier); and (iv) Scopus (Elsevier). Google and Bing were searched for grey literature. Three JBI-trained independent reviewers completed screening to extraction. Community consultation was conducted using the Delphi Method. Of 2217 results, 67 were included in the review (29 peer-reviewed; 38 grey). Identified frequencies were 67 examples of perception, 54 of experience, and 51 of knowledge. This review identified diverse definitions/perspectives of weight-related evidence, highlighting the benefits of continuing to discuss and explore this topic within and beyond dietetics. Weight-related evidence was identified in nutrition care in various settings, representing nutrition assessment, diagnoses, interventions, monitoring, and evaluation. Focused on dietetic research and practice, this work provides a foundation for future evaluation of dietitian-led intervention fidelity, utility, and effectiveness, using systematic review or other research designs. These Canadian findings can serve as a foundation for a global/international review.

Résumé

Dans cette étude de la portée, « données probantes liées au poids » désigne divers termes, formulations et façons de décrire le poids, la taille du corps, l’adiposité et/ou l’obésité qui sont utilisés dans la recherche ou la pratique de la diététique. Les perceptions, expériences et/ou connaissances des diététistes au Canada concernant les données probantes liées au poids dans le contexte des soins nutritionnels ont été identifiées et cartographiées. Quatre bases de données ont été consultées en appliquant la méthodologie de l’étude de la portée JBI : (i) CINAHL (EBSCO); (ii) MEDLINE (Ovid); (iii) Embase (Elsevier); et (iv) Scopus (Elsevier). Des recherches de littérature grise ont aussi été effectuées sur Google et Bing. Trois réviseurs indépendants formés par le JBI ont fait la sélection et l’extraction. Une consultation de la communauté a été menée à l’aide de la méthode Delphi. Sur 2217 résultats, 67 ont été inclus dans l’étude (29 révisés par les pairs; 38 gris). Les fréquences identifiées étaient les suivantes : 67 exemples de perceptions, 54 d’expériences et 51 de connaissances. Cette étude a permis d’identifier diverses définitions/perspectives des données probantes liées au poids, soulignant les avantages de poursuivre la discussion et l’exploration à ce sujet dans le contexte de la diététique et au-delà. Des données probantes liées au poids ont été identifiées dans divers contextes des soins nutritionnels, notamment l’évaluation nutritionnelle, les diagnostics, les interventions, la surveillance et l’évaluation. Ce travail axé sur la recherche et la pratique en diététique jette les bases d’une évaluation future de la fidélité, de l’utilité et de l’efficacité des interventions menées par des diététistes au moyen d’une revue systématique ou d’autres plans de recherche. Ces résultats canadiens peuvent servir de fondement à une étude mondiale.
