Abstract

Background: Dieting is proven to be ineffective for weight management. Research shows that non-diet approaches, such as intuitive eating (IE), improve weight status and health outcomes. Cognitive factors may influence Registered Dietitian Nutritionists’ (RD/Ns) dietary and IE attitudes and practices. RD/Ns play an important role in communicating diet and non-diet approaches in practice with clients. IE can only be communicated to clients by RD/Ns as strongly as RD/Ns practice IE.

Objective: The primary goal of this research was to assess and evaluate Registered Dietitians intuitive eating attitudes and dietary behaviors and practices. RD/Ns IE scores were compared to their body mass index (BMI) and dietary quality. RD/Ns IE philosophies were qualitatively analyzed and compared to their IE scores. A final objective of this research was to validate a current instrument intended to measure RD/Ns IE attitudes, knowledge and practices.

Methods: A cross-sectional study design was used. Participants without the RD/N title were excluded. The survey consisted of five sections:1. Demographics; 2. 24-hour recall; 3. Eating philosophy; 4. Intuitive Eating Scale-2 (IES-2); 5. Validation instrument. IES-2 scores were calculated; the sample was divided into high, moderate and low IES-2 score groups. Twenty four-hour recalls were analyzed and Healthy Eating Index (HEI) scores were computed. Eating philosophies were analyzed for emerging IE and non-IE themes. Themes were totaled into IE and Non-IE theme scores. Validation scores were calculated and examined for the entire sample and a subsample of RD/Ns who practiced weight management counseling.

Results: Mean IES-2 score was 3.73 ± 0.47. BMI was negatively correlated to IES-2 scores (n=83, r= -.354, p=.001). No relationship was observed between IES-2 and HEI scores. A variety of non-IE themes emerged (e.g. restriction) from the qualitative analysis. There was a positive correlation between IES-2 and IE theme scores (r=.294, p=.007, n=84). Validation tool: Attitude was positively correlated to IES-2 scores (n=82, r=.242, p<.028). Subsample: Total validation score and all validation tool sub scores were positively correlated to IES-2 scores [Total (n=53, r=.413, p=.002), practices (n=55, r=.439, p=.001), knowledge (n=55, r=.282, p=.037) and attitudes (n=57, r=.291, p=.028)]. An Independent t-test confirmed significant differences between RD/Ns that practiced weight management counseling and those that did not for IE theme scores (2.03 ± 1.17 vs 1.35 ± 1.29, p=.025), attitudes (10.58 ± 2.36 vs 8.71 ± 3.39, p=.010) and knowledge (25.12 ± 3.37 vs 23.24 ± 2.74, P=.019).

Conclusion: RD/Ns reported conflicting dietary practices that were both consistent and not consistent with the IE principles. RD/Ns who practiced weight management counseling had more positive attitudes towards and knowledge of IE than those who did not. RD/Ns who practiced weight management counseling also reported IE themes more frequently. RD/Ns who practice weight management counseling may be more knowledgeable of IE related to more frequent exposure of IE. Non-IE themes were still well represented in the entire sample suggesting that RD/Ns’ may have conflicting IE attitudes and behaviors. This research can be used to assess and determine future dietetic training needs to benefit dietetic students, Registered Dietitians, clients and patients.
