Interdisciplinary lifestyle therapy improves binge eating symptoms and body image dissatisfaction in Brazilian obese adults

Abstract

Introduction: Obesity is related to numerous negative consequences for physical and mental health. It is often associated with the presence of binge eating disorder, body image dissatisfaction, and general psychopathology.

Objective: To assess the effects of an interdisciplinary lifestyle therapy on binge eating symptoms, depression, anxiety, body dissatisfaction, and quality of life in obese adults.

Methods: A total of 49 obese adults (body mass index = 37.35±5.82 kg/m²; age = 44.14±10.00 years) participated in a weight-loss program for 6 months. Symptoms suggestive of binge eating, body dissatisfaction, depression, anxiety, and quality of life were measured using self-reported questionnaires. Food intake was assessed using a 3-day dietary record. Data were analyzed using analysis of variance (ANOVA).

Results: ANOVA results showed a reduction in binge eating symptoms and in body dissatisfaction results. Depression and anxiety symptoms also decreased, and an increase was observed in quality of life scores. After therapy, a significant improvement was observed in dietary patterns, as well as significant weight loss. A positive correlation was found between variation of anxiety symptoms and lipid intake. Binge eating symptoms were associated with anxiety symptoms and body image dissatisfaction, and body image dissatisfaction correlated positively with anxiety symptoms in males only. In females, a positive correlation was observed between depression and binge eating symptoms.

Conclusion: The interdisciplinary therapy was effective in promoting positive physical and psychological changes and in improving the quality of life of obese adults.
