10 Binge Eating Disorder DSM-IV Recurrent episodes of binge eating Binge eating episode: Eating in a discrete period of time an amount of food that is definitely larger than most people would eat in a similar period of time in similar circumstances A sense of lack of control over eating during the episode The binge eating episodes are associated with at least three of the following: Eating more rapidly than normal Eating until feeling uncomfortably full Eating large amounts of food when not physically hungry Eating alone because of being embarrassed by how much one is eating Feeling disgusted with oneself, depressed, or guilty after overeating. Marked distress regarding binge eating The binge eating occurs, on average at least 2 days a week for six months. The binge eating is not associated with regular use of inappropriate compensatory behaviours and does not occur exclusively during the course of anorexia nervosa or

11 Binge Eating Disorder Frequent weight fluctuations Childhood weight gain Higher levels of psychological co-morbidity compared to those without BED Female BMI>40 Kg/m 2 Yanovski, 1993, Friedman & Brownell, 2002 A healthier weight through lasting lifestyle changes

12 Prevalence of BED General population: 3% (Hudson et al 2007) Obese population: 10% Treatment seeking obese population: 30% (Blaine & Rodman, 2007) Half of outpatient diagnoses (Fairburn et al, 2009)

13 Clinical Experience Other individuals present with sub-clinical disordered eating requiring psychological intervention: compulsive eating using food as an emotional coping strategy dysfunctional eating patterns

14 Weight Loss Interventions & BED Matched study meta-analysis, obese patients with BED lost 2% of body weight compared with 11% in non-bed participants (Blaine and Rodman, 2007) Presence of disordered eating may reduce motivation and adherence to treatment (Hainer et al., 2005) A healthier weight through lasting lifestyle changes

15 BED Interventions and Weight Loss Systematic review of 7 RCTs comparing individual and group interventions in patients with BED, found CBT was effective in reducing binge eating and improving abstinence, but does not lead to weight loss. (Brownley, 2007, Wilson, 2010) The effectiveness of CBT in reducing binge frequency but without influencing weight loss was also confirmed in an RCT with two years follow up. (Devlin et al., 2005) Glasgow & Clyde Weight Management Service

16 BED and Mood Increased levels of depression are seen in adults with severe obesity (BMI>40kg/m 2 ) and obese adults with BED. (Onyike et al, 2003) Increased rates of anxiety and lower levels of self esteem are also observed in obese adults with BED compared to non bingeing obese adults. (Jirik-Bibb and Geliebter, 2003) In addition to the above BED is also associated with guilt and shame. (APA, 2000)

17 Predictors of Outcome Baseline high level of negative affect lead to less weight loss. Increased severity of disordered eating is observed in people with higher negative affect and increased psychiatric co morbidities. Lifetime history of depression predicted less remission from binge eating behaviours. (Wilson et al, 2010) Glasgow & Clyde Weight Management Service
