Compulsive Exercise

Abstract Background Compulsive exercise is a core feature of both eating disorders and muscle dysmorphia. Earlier models of treatment recommended complete abstinence from exercise in eating disorder populations, but recent guidelines advocate for the gradual inclusion of healthier forms of exercise into an overall treatment plan where appropriate. Given the association between problematic exercise behaviour and poorer prognosis, there has been a recent upsurge in the number of treatment interventions for compulsive exercise in eating disorders. However, no systematic review has been published summarising this existing treatment literature. The aim of this review is to determine the efficacy of existing treatments for compulsive exercise in eating disorders and muscle dysmorphia. Methods A systematic review will be conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Five electronic databases (PsycInfo, MEDLINE, Embase, Web of Science, and Scopus) will be searched from database inception until November 2020. We will include studies that: (a) sampled adolescents and/or adults with either an eating disorder or muscle dysmorphia; (b) assessed changes in compulsive exercise from pre- to post-intervention; and (c) used a standardised instrument to measure compulsive exercise or related constructs. We will include studies with a comparison group (e.g., randomised controlled trials) and without a comparison group (e.g., pilot studies and case studies) to provide a comprehensive overview of the literature. One reviewer will screen all titles and abstracts against eligibility criteria, with 20% of excluded articles cross-referenced by another reviewer. Full texts will be obtained for articles deemed relevant or where inclusion was uncertain, and will be screened by both reviewers. We will also evaluate the quality of the included studies using a modified Downs and Black (J Epidemiol Community Health 52:377–384, 1998) assessment checklist. Discussion Results from this review will help to determine the most efficacious treatment components for compulsive exercise in eating disorders and muscle dysmorphia. We hope that our results will help inform clinical practice guidelines in recommending targeted interventions for the treatment of compulsive exercise.

Background: Eating disorders are serious mental disorders and are associated with substantial economic and social burden. The aim of this study is to undertake a systematic review of the cost-effectiveness studies of both preventive and treatment interventions for eating disorder. Method: Electronic databases (including the Cochrane Controlled Trial Register, MEDLINE, PsycINFO, Academic Search Complete, Global Health, CINAHL complete, Health Business Elite, Econlit, Health Policy Reference Center and ERIC) were searched for published cost-effectiveness studies of eating disorder prevention and treatment including papers published up to January 2017. The quality of studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. Results: In all, 13 studies met the review inclusion criteria as full cost-effectiveness studies and 8 were published since 2011. The studies included three modelled and one trial-based study focused on prevention, two trial-based and one modelled study for anorexia nervosa treatment and three trial-based studies for bulimia nervosa treatment. The remaining studies targeted binge-eating disorder or non-specific eating disorder treatment. The average percent of CHEERS checklist items reported was 71% (standard deviation 21%). Eating disorder interventions were mainly cost-saving or more effective and more costly compared to comparators; however, some results did not reach statistical significance. In the two studies that achieved 100% CHEERS checklist, one study reported that a cognitive dissonance intervention might be cost-effective for prevention of anorexia nervosa and bulimia nervosa with a 90% participation rate and the second study supported lisdexamfetamine to be cost-effective in the treatment of binge-eating disorder. Insufficient evidence for long-term cost-effectiveness (e.g. over 2 years) was found. Conclusion: Cost-effectiveness studies in eating disorder appear to be increasing in number over the last 6 years. Findings were inconsistent and no firm conclusion can be drawn with regard to comparative value-for-money conclusions. However, some promising interventions were identified. Further research with improved methodology is required.

Background. Eating problems are highly prevalent among young adults. Universities could be an optimal setting to prevent eating disorders through psychological intervention. As part of the World Mental Health-International College Student initiative, this systematic review and meta-analysis synthesizes data on the efficacy of eating disorder prevention programs targeting university students.Method. A systematic literature search of bibliographical databases (CENTRAL, MEDLINE, PsycINFO) for randomized trials comparing psychological preventive interventions for eating disorders in university students to psychoeducation or inactive controls was performed through October 8th, 2018.Results. Twenty-two studies were included. Eight (36.4%) were rated to have a low risk of bias. The relative risk of developing a subthreshold or full-blown eating disorder was IRR=0.62 (95%CI: 0.44-0.87, n=8; standardized clinical interviews only), indicating a 38% decrease in incidence in the intervention groups compared to controls. Small to moderate between- group effects at post-test were found on self-reported global eating disorder symptoms (g=0.36, 95%CI: 0.25-0.47, n=20), dieting (g=0.47, 95%CI: 0.30- 0.64, n=18), body dissatisfaction (g=0.50, 95%CI: 0.33-0.67, n=14), drive for thinness (g=0.43, 95%CI: 0.27-0.59, n=12), weight concerns (g=0.33, 95%CI: 0.10-0.57, n=13) and affective symptoms (g=0.28, 95%CI: 0.16-0.40, n=14). Effects on bulimia were not significant. Heterogeneity was low to moderate across comparisons.Discussion. Eating disorder prevention on campus can have significant, small-to-moderate effects on eating disorder symptoms and risk factors. Results also suggest that the prevention of subthreshold and full-syndrome eating disorders is feasible using such interventions. More research is needed to identify effects on academic functioning, as well as ways to motivate students to use preventive eating disorder interventions.

Eating disorders are widespread illnesses with significant impact. There is growing concern about how those at risk of eating disorders overuse online resources to their detriment. We conducted a pre-registered systematic review and meta-analysis of studies examining Problematic Usage of the Internet (PUI) and eating disorders. The meta-analysis comprised n=32,295 participants, in which PUI was correlated with significant eating disorder psychopathology Pearson r=0.22 (s.e.=0.04, p<0.001), body dissatisfaction r=0.16 (s.e.=0.02, p<0.001), drive-for-thinness r=0.16 (s.e.=0.04, p<0.001) and dietary restraint r=0.18 (s.e.=0.03). Effects were not moderated by gender, PUI facet or study quality. Results are in support of PUI impacting significantly on vulnerable populations towards the development or maintenance of eating disorder psychopathology; males may be equally vulnerable to these potential effects. Prospective and experimental studies in the field suggest that small but significant effects exist and may have accumulative influence over time and across all age groups. Those findings are important to expand our understanding of PUI as a multifaceted concept and its impact on multiple levels of ascertainment of eating disorder psychopathology.

Background: Patients in the postoperative period following bariatric surgery are at risk of developing eating disorders. This study aims to analyze the relation between bariatric surgery and the development and recurrence of eating disorders. Material and methods: A literature review was carried out on 15 November 2020. Fourteen studies that met the eligibility criteria were included for qualitative synthesis, and 7 studies for meta-analysis. Results: The prevalence of eating disorders in the postoperative period was 7.83%, based on the 7 studies in the meta-analysis. Binge eating disorder alone was 3.81%, which was the most significant factor, and addressed in 6 of these studies. Conclusion: The investigated studies have significant methodological limitations in assessing the relation between bariatric surgery and eating disorders, since they mostly present data on prevalence.

This systematic review analysed published data on the effectiveness of enhanced cognitive behaviour therapy (CBT-E) for adolescents with eating disorders. Of the 28 papers retrieved, eight (6 case series, 1 prospective cohort study, and 1 non-randomized effectiveness trial) met the inclusion criteria and revealed the following five findings. First, outpatient CBT-E is well accepted by adolescent patients with anorexia nervosa; it is completed by about two-thirds of participants, and produces improvements in eating-disorder and general psychopathology. Remission from anorexia nervosa is achieved by about 50% of patients at 12-month follow-up. Second, outpatient CBT-E seems more effective for adolescents than adults. Third, inpatient CBT-E for adolescents with anorexia nervosa seems particularly effective — about 80% of patients achieve normal weight by 12-month follow-up. Fourth, CBT-E also seems promising for adolescents who are not underweight. Fifth, CBT-E appears to yield similar outcomes to FBT in terms of weight regain and eating-disorder and general psychopathology improvements at 6- and 12-month follow-up. The fourth and fifth findings derive from a single study and require confirmation. In conclusion, CBT-E is a viable and promising treatment for adolescents with eating disorders.

Electrophysiological Findings

Binge-purge eating disorders (BP-ED), such as bulimia nervosa and binge eating disorder, may share some neurobiological features. Electroencephalography (EEG) is a non-invasive measurement modality that may aid in research and diagnosis of BP-ED. We conducted a systematic review of the literature on EEG findings in BP-ED, seeking to summarize and analyze the current evidence, as well as identify shortcomings and gaps to inform new perspectives for future studies. Following PRISMA Statement recommendations, the PubMed, Embase, and Web of Science databases were searched using terms related to “electroencephalography” and “binge-purge” eating disorders. Of 555 articles retrieved, 15 met predefined inclusion criteria and were included for full-text analysis. Eleven studies investigated EEG by means of event-related potentials (ERP) in BP-ED individuals: 7 using eating disorder-related stimuli (i.e., food, body image) and 4 using non-eating disorder-related stimuli (i.e., facial expressions or auditory clicks). These studies found significant differences in the N200, P200, P300, and LPP components in BP-ED participants compared to controls, indicating that this population exhibits impairments in selective attention, attentional allocation/processing, and allocation of motivational or emotion-based attention. Five studies investigated EEG using frequency analysis; reporting significant differences in beta activity in fronto-temporal and occipito-temporo-parietal areas in BP-ED individuals compared to controls, revealing a dysfunctional brain network. However, the small number of studies, the heterogeneity of samples, study paradigms, stimulus types, and the lack of an adequate assessment of neuropsychological parameters are some limitations of the current literature. Although some EEG data are promising and consistent with neuroimaging and neuropsychological findings in individuals with BP-ED, future studies need to overcome current methodological shortcomings.
