Abstract

Purpose: To assess dietitians’ perspectives on the importance and applicability of interventions to enhance adherence to dietary advice for preventing and managing chronic diseases in adults in the Canadian context.
Methods: Based on a Cochrane systematic review, we identified 8 promising interventions for enhancing adherence to dietary advice: behavioural contracts, exchange lists, feedback based on self-monitoring, individualized menu suggestions, multiple interventions, portion size awareness, telephone follow-up, and videos. Thirty-two dietitians then completed a 3-round Delphi study by responding to an electronic questionnaire asking them to rate the importance and applicability in their practice of the 8 interventions on a 7-point Likert scale.
Results: Using a ≥75% level of agreement, 4 interventions showed strong consensus: multiple interventions, feedback based on self-monitoring, portion size awareness, and videos. Among these, the most significant were (means ± SD for importance and applicability, respectively) feedback based on self-monitoring (6.97 ± 0.18 and 6.72 ± 0.46), portion size awareness (6.69 ± 0.54 and 6.75 ± 0.51), and multiple interventions (6.94 ± 0.25 and 6.81 ± 0.40).
Conclusions: These findings can guide the development of educational training sessions for dietitians to help them provide practice-relevant interventions that will increase the likelihood that patients adhere to their advice regarding prevention and management of chronic diseases.

Résumé

Objectif. Évaluer les perspectives des diététistes quant à l'importance et à l'applicabilité des interventions destinées à améliorer l'adhésion aux conseils nutritionnels visant la prévention et la gestion des maladies chroniques chez les adultes en contexte canadien.
Méthodes. À l'aide d'une revue systématique Cochrane, nous avons identifié 8 interventions prometteuses pour améliorer l'adhésion aux conseils nutritionnels : contrats comportementaux, listes d’échanges, rétroaction basée sur l'autosurveillance, suggestions de menus personnalisés, interventions multiples, sensibilisation à la taille des portions, suivi téléphonique et vidéos. Trente-deux diététistes ont ensuite participé à une étude Delphi en 3 phases en répondant à un questionnaire électronique où ils devaient évaluer l'importance et l'applicabilité des 8 interventions dans leur pratique sur une échelle de Likert en 7 points.
Résultats. En fonction d'un niveau d'accord ≥ 75 %, 4 interventions ont montré un fort consensus : les interventions multiples, la rétroaction basée sur l'autosurveillance, la sensibilisation à la taille des portions et les vidéos. Les plus significatifs (moyennes ± écarts-types pour l'importance et l'applicabilité, respectivement) étaient la rétroaction basée sur l'autosurveillance (6,97 ± 0,18 et 6,72 ± 0,46), la sensibilisation à la taille des portions (6,69 ± 0,54 et 6,75 ± 0,51) et les interventions multiples (6,94 ± 0,25 et 6,81 ± 0,40).
Conclusions. Ces conclusions peuvent orienter le développement de séances de formation pour les diététistes en vue de les aider à faire des interventions pertinentes sur le plan de la pratique qui augmenteront la probabilité que les patients suivent leurs conseils sur la prévention et la gestion des maladies chroniques.
