Abstract	Background: There is a strong association between perfectionism and eating disorders. In a cognitive-behavioural model of compulsive exercise it has been suggested there are reciprocal associations between perfectionism, eating disorder pathology, and compulsive exercise. No study has examined if there is an indirect association between perfectionism and compulsive exercise through eating disorder pathology, which would inform a preliminary understanding of the cognitive-behavioural model of compulsive exercise. Methods: The sample included 301 adolescent females diagnosed with eating disorders (age M = 14.89, SD = 0.85, range 13-17). We tested models of direct and indirect associations of compulsive exercise in the relationship between perfectionism and eating disorder pathology, and direct and indirect associations of eating disorder pathology in the relationship between compulsive exercise and perfectionism. Results: Perfectionism was directly associated with eating disorder pathology and compulsive exercise. Perfectionism was indirectly associated with eating disorder pathology through compulsive exercise. Perfectionism also had an indirect association with compulsive exercise through eating disorder pathology. Discussion: The findings suggest it would be useful for future prospective research to examine the cognitive-behavioural model of compulsive exercise in adolescents with eating disorders. Compulsive exercise and perfectionism may be useful targets for future research to improve eating disorder treatment. Level of evidence Level V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Abstract	Background: Living in a food-insecure or food insufficient household may increase risk for binge eating and obesity. Because racial disparities in food access, obesity, and access to treatment for disordered eating exist, it is important to examine these relationships in Black populations. Methods: We conducted a secondary analysis of data from the National Survey of American Life (N = 4553), a nationally-representative sample of Black Americans, including African Americans and Afro-Caribbeans. Logistic regression was used to explore the association of food insufficiency with obesity and binge eating. Results: In the total sample of Black Americans, the prevalence of food insufficiency was 10.9% (95% CI 10.0-11.8%). Food insufficiency was not significantly associated with obesity in Black Americans, but when associations were explored in analyses stratified by ethnicity and sex, food insufficiency significantly predicted an increased odds of obesity in Afro-Caribbeans (odds ratio [OR] = 1.47, 95% CI 1.01, 2.13). Individuals experiencing food insufficiency were more likely to report recurrent binge eating in the last 12 months (3% v 2%, P = 0.02) and a lifetime history of binge eating (6% v 3%, P = 0.004) compared to those who were food sufficient. After adjusting for socio-demographic factors, food insufficiency was not significantly associated with recurrent binge eating in Black Americans or in sex- and ethnicity-stratified analyses. Conclusion: The present study reveals a more complex relation between food insufficiency and binge eating than previously thought-although an association existed, it was attenuated by an array of sociodemographic factors. Our results also underscore the importance of considering ethnicity as different patterns emerged between African American and Afro-Caribbean participants.

Abstract	Perfectionism has a strong association with eating disorders. Research in non-clinical adults has suggested that perfectionism has both direct and indirect effects on eating disorder symptoms, and that compulsive exercise is a potential mediator. The aim of this study was to understand whether perfectionism is associated with eating disorder symptoms, both directly and indirectly through compulsive exercise in underweight adolescents with eating disorders. Participants were 149 female adolescents (M = 14.90 years, age range 13-17) with eating disorders from the Helping to Outline Paediatric Eating Disorders (HOPE) Project, an ongoing, registry study of individuals consecutively referred individuals to a statewide eating disorder service. The majority had a diagnosis of anorexia nervosa restricting type (66 %), followed by unspecified feeding or eating disorder (21 %), and anorexia nervosa binge-eating purging type (13 %). To test the model, path analyses with bootstrapping were conducted. All paths were statistically significant, including the indirect effect from perfectionism to eating disorder pathology via the mediator of compulsive exercise, and the direct effect of perfectionism on eating disorder pathology. Overall, this research provides further evidence that compulsive exercise may be one factor that can explain the relationship between perfectionism and eating disorder symptoms. Future research should seek to determine the relative efficacy of approaches for the treatment of eating disorders in adolescents which target perfectionism and compulsive exercise.

Abstract	Enabled by advances in high throughput genomic sequencing and an unprecedented level of global data sharing, molecular genetic research is beginning to unlock the biological basis of eating disorders. This invited review provides an overview of genetic discoveries in eating disorders in the genome-wide era. To date, five genome-wide association studies on eating disorders have been conducted - all on anorexia nervosa (AN). For AN, several risk loci have been detected, and ~11-17% of the heritability has been accounted for by common genetic variants. There is extensive genetic overlap between AN and psychological traits, especially obsessive-compulsive disorder, and intriguingly, with metabolic phenotypes even after adjusting for body mass index (BMI) risk variants. Furthermore, genetic risk variants predisposing to lower BMI may be causal risk factors for AN. Causal genes and biological pathways of eating disorders have yet to be elucidated and will require greater sample sizes and statistical power, and functional follow-up studies. Several studies are underway to recruit individuals with bulimia nervosa and binge-eating disorder to enable further genome-wide studies. Data collections and research labs focused on the genetics of eating disorders have joined together in a global effort with the Psychiatric Genomics Consortium. Molecular genetics research in the genome-wide era is improving knowledge about the biology behind the established heritability of eating disorders. This has the potential to offer new hope for understanding eating disorder etiology and for overcoming the therapeutic challenges that confront the eating disorder field.

Abstract	Latinos/as are underrepresented in eating disorders clinical trials. This study compared results of a culturally adapted individual cognitive-behavioral treatment (CBT) for binge-spectrum eating disorders that included or excluded a family enhanced module (CBT + FE), in a proof-of-principle pilot study with a sample of Latina adults and one family member per patient. Twenty-five patients (Mₐgₑ = 37 yrs) and 25 family members (Mₐgₑ = 40 yrs) were randomized to CBT (n = 13) or CBT+ FE (n = 12). DSM-IV eating disorder diagnoses were: 48% (n = 12) bulimia nervosa, 28% (n = 7) binge-eating disorder, and 24% (n = 6) eating disorder not otherwise specified. Effect sizes favored CBT + FE on adherence and retention, and scores on treatment satisfaction and therapeutic alliance were high, indicating treatment acceptability. In spite of the hypothesis that family outcomes such as support, familism, cohesion, pride, family cultural conflict, burden, and marital satisfaction (in couples) would be superior in CBT + FE, the preliminary data were inconclusive and results were mixed. The hypothesis that eating disorder outcomes including global eating psychopathology, binge eating, and purging would improve in CBT + FE was not supported. There was some evidence that patients in CBT improved more particularly on binge eating, otherwise the groups had no differences. In conclusion, the results suggest that CBT + FE could enhance treatment adherence and retention, although this did not automatically translate to better family and symptom outcomes.

Abstract	Eating disorders (anorexia nervosa, bulimia nervosa and binge-eating disorder) are a heterogeneous class of complex illnesses marked by weight and appetite dysregulation coupled with distinctive behavioral and psychological features. Our understanding of their genetics and neurobiology is evolving thanks to global cooperation on genome-wide association studies, neuroimaging, and animal models. Until now, however, these approaches have advanced the field in parallel, with inadequate cross-talk. This review covers overlapping advances in these key domains and encourages greater integration of hypotheses and findings to create a more unified science of eating disorders. We highlight ongoing and future work designed to identify implicated biological pathways that will inform staging models based on biology as well as targeted prevention and tailored intervention, and will galvanize interest in the development of pharmacologic agents that target the core biology of the illnesses, for which we currently have few effective pharmacotherapeutics.

Abstract	Background and objectives: Guided and unguided self-help prevention and treatment interventions for eating disorders delivered via traditional book format or internet delivery have been widely researched, but no reviews have focused specifically on young people. The aim of this systematic review and meta-analysis was to examine the efficacy of randomised controlled trials of self-help interventions for eating disorders in young people with a mean age between 13 and 24 years. Methods: A total of 8 intervention groups across 7 publications of self-help interventions which were prevention and treatment trials for eating disorders, were identified (N = 985 participants; mean pooled age = ∼19 years). Results: There was a significant very small effect (pooled g = -0.17) of self-help interventions at post-treatment which was non-significant at follow-up (pooled g = -0.14). No evidence of publication bias was found. Limitations: There were limitations of the review, including a lack of active treatment comparisons, a small number of trials included, and few studies included an age range. Conclusions: Results from this preliminary meta-analysis suggest very small but significant effects, however further studies are required to determine whether self-help approaches are effective for prevention and treatment of eating disorder symptoms in young people. Future meta-analyses should include a larger number of trials, and younger age range of children to examine the efficacy of self-help interventions for eating disorders in young people.
