Obesity and quality of life

The focus of this review is the impact of obesity and weight loss on quality of life. A focus on quality of life broadens the scope of treatment efficacy beyond weight loss and provides a patient-centered perspective. The concept of quality of life is defined, and both general and obesity-specific measures are reviewed. It is clear that obesity confers negative consequences on both the physical and psychosocial aspects of quality of life, especially among the severely obese. The effects of weight loss appear to be favorable, although few studies have examined non-surgical interventions. Future studies would be enhanced by assessing a variety of approaches to weight loss by using both general and obesity-specific measures of quality of life and conducting follow-up studies to assess the effects of weight regain on quality of life.
