'': exploring experiences and perspectives of registered dietitians from Canada about their interactions with commercial actors using semi-structured interviews.

Objective: To gain insight into the experiences and perspectives of registered dietitians (RD) in Canada regarding their interactions with commercial actors and actions undertaken to manage these interactions.

Design: Qualitative study using semi-structured interviews combined with a document analysis.

Setting: Quebec, Canada.

Participants: RD aged ≥ 18 years ( 18).

Results: All participants reported interacting with commercial actors during their careers, such as receiving continuing education provided or sponsored by food companies. RD in Quebec perceive these interactions as either trivial or acceptable, depending on the commercial actor or interaction type. Participants discussed how certain interactions could represent a threat to the credibility and public trust in dietitians, among other risks. They also discussed the benefits of these interactions, such as the possibility for professionals to improve the food supply and public health by sharing their knowledge and expertise. Participants reported ten mechanisms used to manage interactions with commercial actors, such as following a code of ethics (individual level) and policies such as partnerships policy (institutional level). Finally, RD also stressed the need for training and more explicit and specific tools for managing interactions with commercial actors.

Conclusions: RD in Quebec, Canada, may engage with commercial actors in their profession and hold nuanced perspectives on this matter. While some measures are in place to regulate these interactions, they are neither standardised nor evaluated for their effectiveness. To maintain the public's trust in RD, promoting awareness and developing training on this issue is essential.
