Eating disorders and exercise: a structural equation modelling analysis of a conceptual model

Area of Science:

• Psychology
• Sports Science
• Public Health

Background:

• Physical activity offers numerous health benefits, yet its specific role in eating disorders (ED) remains debated.
• Understanding the mechanisms linking exercise and ED is crucial for effective prevention and treatment strategies.

Purpose of the Study:

• To test a conceptual model proposing that regular, non-compulsive exercise can positively influence eating disorder prevention and treatment.
• To investigate the relationship between exercise, psychological well-being, and eating disorder risk.

Main Methods:

• A sample of 539 university students completed self-report measures.
• Data included quality of life, exercise habits, eating disorder risk, and exercise dependence symptoms.
• Structural equation modeling was used to analyze the proposed relationships within the conceptual model.

Main Results:

• The analysis favored a partially mediated model that excluded physical well-being as a direct factor.
• Mediation analysis indicated that psychological benefits derived from exercise were significantly associated with lower eating disorder risk.
• Physical benefits of exercise did not show a direct association with reduced eating disorder risk in this model.

Conclusions:

• The findings offer preliminary support for the conceptual model, highlighting the importance of psychological factors in the exercise-ED relationship.
• Psychological benefits of exercise, such as improved mood and reduced anxiety, appear more critical than physical benefits in mitigating eating disorder risk.
• Further research is warranted to fully elucidate the complex interplay between exercise, psychological health, and eating disorders.
