Relapse is a substantial problem in eating disorders. Until recently, there have been few investigations into maintenance treatments aimed at helping patients maintain improvements made in treatment. This study compared the outcomes of group-based intensive outpatient versus individual cognitive behavioural therapy (CBT)-based maintenance treatments for eating disorders, following inpatient or day treatment. In this sequential cohort study, patients received the type of maintenance treatment (intensive outpatient group or individual CBT) available at the time. A total of 221 patients with eating disorders were included, and data were examined retrospectively. Cox regression was used to determine whether treatment type predicted rate of return to clinically significant symptoms over the 12 months following inpatient or day treatment. Intensive outpatient group versus individual CBT maintenance treatment did not predict differential rate or trajectory of return to clinically significant symptoms in diagnostic subgroups and the overall sample. Maintenance treatment type did not predict changes in weight/shape concerns between end-of-inpatient or day treatment) and 6- or 12-month follow-up (after controlling for diagnosis). Although the treatments appeared similarly effective in helping patients maintain gains made in intensive treatment, individual CBT may be a more time- and cost-efficient approach to delivering maintenance treatment.

Background: Individuals with eating disorders have a high mortality risk. Few population-based studies have estimated this risk in eating disorders other than anorexia nervosa.Aims: To investigate all-cause mortality in a population-based cohort of individuals who received hospital-based care for an eating disorder (anorexia nervosa, bulimia nervosa or eating disorder not otherwise specified) in Ontario, Canada.Method: We conducted a retrospective cohort study of 19 041 individuals with an eating disorder from 1 January 1990 to 31 December 2013 using administrative healthcare data. The outcome of interest was death. Excess mortality was assessed using standardised mortality ratios (SMRs) and potential years of life lost (PYLL). Cox proportional hazards regression models were used to examine sociodemographic and medical comorbidities associated with greater mortality risk.Results: The cohort had 17 108 females (89.9%) and 1933 males (10.1%). The all-cause mortality for the entire cohort was five times higher than expected compared with the Ontario population (SMR = 5.06; 95% CI 4.82-5.30). SMRs were higher for males (SMR = 7.24; 95% CI 6.58-7.96) relative to females (SMR = 4.59; 95% CI 4.34-4.85) overall, and in all age groups in the cohort. For both genders, the cohort PYLL was more than six times higher than the expected PYLL in the Ontario population.Conclusions: Patients with eating disorders diagnosed in hospital settings experience five to seven times higher mortality rates compared with the overall population. There is an urgent need to understand the mortality risk factors to improve health outcomes among individuals with eating disorders. [ABSTRACT FROM AUTHOR]

Objective: Eating disorders are common and have a high public health burden. However, existing clinically relevant data sources are scarce, limiting the capacity to accurately measure the burden of eating disorders. This study tests the feasibility of generating a large clinically relevant cohort of individuals with eating disorders using health administrative data.Methods: We developed 3 clinically relevant eating disorder prevalence cohorts using health administrative data from Ontario, Canada, between 1990 and 2014. Cohort 1 included patients with a hospitalization where an eating disorder diagnosis was the primary diagnosis, cohort 2 included patients with a hospitalization where an eating disorder diagnosis was any diagnosis, and cohort 3 included cohort 2 plus any patient with an emergency department visit with an eating disorder diagnosis.Results: Cohort 1 had 7268 patients, cohort 2 had 13,197 patients, and cohort 3 had 17,373 patients. As cohort size increased, the proportion of eating disorder patients with diagnoses of bulimia nervosa and eating disorder not otherwise specified increased. Although the cohorts differed according to demographic and clinical characteristics, these differences were small compared to the degree to which they differed from the Ontario population.Discussion: It is feasible to use health administrative data to measure the clinically relevant burden of eating disorders. The cohorts differed significantly in the eating disorder diagnostic composition. Eating disorders have a high burden, but poor data availability has resulted in fewer public health-related eating disorders studies in comparison to other mental disorders. The use of administrative data can address this evidence gap. [ABSTRACT FROM AUTHOR]

The false-hope syndrome suggests that unrealistic expectations about dieting set dieters up for failure and then promote renewed efforts at weight loss. Studies show that restrained eaters had higher expectations for themselves than did unrestrained eaters, and restrained and unrestrained eaters had similar expectations concerning dieting for others.
