Eating disorders and obesity are independent public health concerns in both developed and developing countries. Nonetheless, there is a significant occurrence of eating disorders, especially binge eating disorder, in individuals with obesity. This is concerning because eating disorders can contribute to obesity and vice-versa. Additionally, individuals with eating disorders as well as comorbid obesity are at higher risk of health complications than individuals with either condition alone. A new treatment designed to simultaneously reduce eating disorder behaviors and assist with weight management - the HAPIFED Program - has been developed. This program - as originally developed in Australia - includes 30 sessions of therapy, nonetheless this extended treatment duration is not suitable for Brazil where resources in the public health system are scarce and private health care is not affordable for a significant proportion of the population. Thus, it is important to develop and test a short-version of the HAPIFED Program because shortened treatment duration can reduce the burden on public health systems and also reduce cost of private treatment. This study compares a short-version of the HAPIFED Program (i.e. 12 sessions of therapy) versus the usual care, cognitive behavior therapy - enhanced (CBT-E) in simultaneously treating binge eating disorder and overweight/obesity. A hundred participants with binge eating disorder and comorbid overweight/obesity will be randomized to group treatment with the short-version of the HAPIFED Program or CBT-E. Eating disorders, body mass index, mental health and quality of life will be assessed at baseline, 12 weeks and 24 weeks after treatment commencement. The outcomes of this study will inform on the effectiveness of a new integrated and time-efficient therapy for individuals with binge eating disorder and comorbid overweight/obesity. (AU)
