Long-term stability of eating disorder diagnoses
About this resource
OBJECTIVE: To estimate the familiality and heritability of binge eating disorder (BED). METHOD: We used a new ACE structural equation model to estimate heritability from a case-control family study of BED conducted in the Boston area. The sample consisted of 150 overweight/obese probands with lifetime BED by DSM-IV criteria, 150 overweight/obese probands without lifetime BED, and 888 of their first-degree relatives. We compared our findings with those from a study of binge eating (in the absence of compensatory behaviors) among 7,831 Norwegian twins. RESULTS: The prevalence of BED differed by sex and by age. In the case-control family study, BED was found to aggregate in families, and heritability was estimated as 57 % (CI: 30-77 % ). Including shared environment did not substantially improve the model's fit, nor did allowing sex-specific heritability. Findings from the twin study were similar. CONCLUSION: BED appears to aggregate in families and have a significant genetic component.
Is family therapy the most effective treatment for anorexia nervosa?
Introduction: Anorexia nervosa is a mental health disorder characterised by deliberate weight loss (through restrictive eating, excessive exercise and/or purging), disordered body image, and intrusive overvalued fears of gaining weight.Read more
Facets of negative affect prior to and following binge-only, purge-only, and binge/purge events in women with bulimia nervosa
Ecological momentary assessment (EMA) data suggest that global negative affect (NA) increases prior to and decreases following episodes of binge eating and purging, providing support for the affect regulation model of BN.Read more
Differentiating purging and nonpurging bulimia nervosa and binge eating disorder
To explore similarities and differences in clinical and personality variables across three groups: binge eating disorder (BED), bulimia nervosa-purging type (BN-P), and bulimia nervosa-non purging type (BN-NP).Read more
Suicide attempts in women with eating disorders
We evaluated whether the prevalence of lifetime suicide attempts/completions was higher in women with a lifetime history of an eating disorder than in women with no eating disorder and assessed whether eating disorder features, comorbid psychopathology, and personality characteristics were associated with suicide attempts in women with anorexia nervosa, restricting subtype (ANR), anorexia nervosa, binge-purge subtype (ANBP), lifetime history of both anorexia nervosa and bulimia nervosa (ANBN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD).Read more
