BACKGROUND The examination of opposite-sex and same-sex dizygotic twins allows us to explore the sex-specific comorbidity of psychiatric disorders. To date, this question has not been explored in eating disorders. OBJECTIVE To determine whether sex influences shared risk factors between bulimia nervosa (BN) and other forms of psychopathology. DESIGN The study examines associations between BN and other forms of psychopathology in twin pairs using interview and survey reports. SETTING Twins…

Prevalence and early risk factors for bulimia nervosa symptoms in inner-city youth: gender and ethnicity perspectives

This longitudinal study evaluated the prevalence of bulimia nervosa symptoms in US inner-city predominantly ethnic minority youth and explored the associations between early risk factors and probable BN one year later.

Psychiatric comorbidity as a risk factor for the mortality of people with bulimia nervosa

Increased mortality in patients with BN is highlighted and the importance of recognising and treating PDs in patientsWith BN, the influence of psychiatric comorbidities with demographic and socioeconomic factors considered as confounders over an observation period is investigated.

Parental disorders, childhood abuse, and binge eating in a large community sample.

Results emphasize the value of models that incorporate nature and nurture to understand risk for psychopathology in offspring, with childhood abuse being one mediator of how parental psychopathology may reflect genetic risk and influence environmental risk.

A behavioral-genetic investigation of bulimia nervosa and its relationship with alcohol use disorder

Prevalence and long-term course of lifetime eating disorders in an adult Australian twin cohort.

The lifetime prevalence and long-term course of anorexia nervosa, bulimia nervosa and eating disorder not otherwise specified (EDNOS) in an adult female twin population is examined and the DSM-IV diagnosis EDNOS needs to be considered in studies of the prevalence and course of eating disorders.

Genetic determinants of eating disorders

The heritability of disordered eating behavior and attitudes in relation with body mass index (BMI) was evaluated in a large adolescent twin-family sample ascertained through the Netherlands Twin Registry and the observed association between the Tryptophan Hydroxylase 2 (TPH2) gene and eating disorders was investigated.

Perceived non-shared environment, personality traits, family factors and developmental experiences in bulimia nervosa.

In the final logistic regression, insecure paternal attachment predicted the risk for BN, while trends were apparent for narcissism and developmental teasing after controlling for psychopathology.

Co-occurrence of eating disorders and alcohol use disorders in women: a meta analysis

The magnitude of the association between BN and AUD was the most divergent across studies and those between each of BED and dietary restriction and AUD were the most consistent across studies.

Eating disorders, substance use disorders, and impulsiveness among disordered gamblers in a community sample.

It is suggested that impulsiveness might constitute a common personality characteristic that underlies disordered gambling and EDs and is associated with increased impulsiveness.



Comorbidity of bulimia nervosa and alcohol use disorders: results from the National Women's Study.

Evaluation of MDD and PTSD in women presenting for treatment of BN and/or alcohol use disorders (AUDs) is recommended, and analyses indicated that the relationship between Bn and AA/AD may be indirect and influenced by associations with MDd and PTSD.

The genetic epidemiology of bulimia nervosa.

The liability to fully syndromal bulimia nervosa, which affects around one in 25 women at some point in their lives, is substantially influenced by both epidemiologic and genetic risk factors.

The structure of the genetic and environmental risk factors for six major psychiatric disorders in women. Phobia, generalized anxiety disorder, panic disorder, bulimia, major depression, and alcoholism.

These results support the following hypotheses: each major risk factor domain influences comorbidity between these disorders in a distinct manner, and most of the genetic factors that influence vulnerability to alcoholism in women do not alter the risk for development of other common psychiatric disorders.

A controlled family study of anorexia nervosa and bulimia nervosa: psychiatric disorders in first-degree relatives and effects of proband comorbidity.

Relatives of anorexic and bulimic probands had increased risk of clinically subthreshold forms of an eating disorder, major depressive disorder, and obsessive-compulsive disorder and obsessional personality traits may be a specific familial risk factor for anorexia nervosa.

Genetic and environmental risk factors for the weight and shape concerns characteristic of bulimia nervosa

Model fitting indicated that there is a powerful role of the environment in shaping women's attitude towards weight, shape, eating and food, and it seems likely that environmental manipulation can be effective in the prevention of bulimia nervosa.

A population-based twin study of lifetime major depression in men and women.

Major depression is equally heritable in men and women, and most genetic risk factors influence liability to MD similarly in the 2 sexes, however, genes may exist that act differently on the risk for MD in men vs women.

Anorexia nervosa and bulimia nervosa in alcohol-dependent men and women and their relatives.

While the rate of anorexia was not elevated in alcoholics after controlling for other disorders, bulimia did occur at a greater than expected rate, and much of the association with alcoholism occurred in the context of additional preexisting or secondary psychiatric disorders.

Bulimia nervosa in a Canadian community sample: prevalence and comparison of subgroups.

This study confirms other prevalence estimates of bulimia nervosa and its comorbid diagnoses from studies that were based on sound methodologies and points to the arbitrary aspects of the frequency of binge eating as a diagnostic threshold criterion for the disorder.
