Abstract

fetched live from OpenAlex

Abstract Background/Objectives Assessment of energy requirements and intake is central to the nutrition care process, yet current practices among registered dietitians (RDs) are not well characterized. This study examined how RDs assess energy requirements and intake, including perceived accuracy and resources, and differences by setting and experience. Methods A cross-sectional bilingual online survey was administered to RDs in Canada. The survey collected information on practice setting and experience, access to variables influencing energy requirements/intake, tool use, and opinions on accuracy and resource needs. Descriptive statistics and comparisons were made by practice setting (clinical, community, other) and years in practice (<5, 5–10, >10 years). Results 212 RDs completed the survey (62% clinical, 16% community, 22% other settings; 36% <5 years, 23% 5–10 years, 42% >10 years of practice). Participants rated importance of assessing energy requirements and energy intake as moderately high (6.8□±□2.2, 7.1□±□2.3 out of 10, respectively) and had regular access to variables needed to calculate energy requirements and intake (e.g., age, sex, weight, disease), although access to body composition, sleep, and stress was limited. Commonly-used tools included body weight-based equations and 24-hour recalls. Confidence was highest for delivering interventions and lowest for assessing intake (p < 0.001), especially among less experienced RDs (p = 0.002). Most respondents expressed interest in improved tools for assessing energy requirements (76%) and intake (74%). Conclusion Current RD practices vary, and access to key data is limited, underscoring the need for validated, accessible tools and training to support accurate energy assessment in dietetic care.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
