Identifying and Mapping Canadian Registered Dietitians' Perceptions and Knowledge of and Experiences with...

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.
