Associations between body image, eating behavior, and diet quality

Area of Science:

• Nutrition Science
• Behavioral Psychology

Background:

• Weight-neutral interventions promoting adaptive eating behaviors are gaining traction.
• Understanding the link between adaptive eating and diet quality is crucial.
• Body image may influence the relationship between eating behaviors and diet quality.

Purpose of the Study:

• To explore the connections between body image (positive and negative), eating behaviors (adaptive and maladaptive), and diet quality.
• To investigate the mediating role of eating behaviors in the relationship between body image and diet quality.

Main Methods:

• 288 US adults completed an online survey assessing body image, eating behaviors, and diet quality via a dietary screener questionnaire (DSQ).
• Hierarchical linear regression was employed to analyze the data.
• Mediation analyses were conducted to test the role of eating behaviors.

Main Results:

• Maladaptive eating behaviors and general body image were not significantly associated with diet quality.
• Body-food choice congruence (B-FCC), an adaptive eating behavior, showed a positive association with diet quality.
• B-FCC mediated the influence of both positive and negative body image on diet quality.

Conclusions:

• Findings support weight-neutral or adaptive eating interventions as effective strategies for enhancing diet quality.
• Further research should examine indirect effects of body image on diet, explore qualitative data on eating behavior and diet quality, and compare weight-neutral interventions with traditional approaches.
