Genetic and environmental factors contribute to the etiology of anorexia nervosa (AN). The co-twin control design is one of the most powerful methods available to evaluate environmental factors that could contribute to differences between monozygotic (MZ) twins who are discordant for AN. Using available data from a unique and rare sample of 22 Swedish female MZ pairs discordant for AN, we compared personality, life events, comorbidity, and health factors. Twins with AN had significantly higher… Expand
Study protocol of comprehensive risk evaluation for anorexia nervosa in twins (CREAT): a study of discordant monozygotic twins with anorexia nervosa
The multimodal longitudinal twin assessment of the CREAT study will help to disambiguate state, trait, and “scar” effects, and enable a deeper understanding of the contribution of genetics, epigenetics, cognitive functions, brain structure and function, metabolism, endocrinology, microbiology, and immunology to the etiology and maintenance of AN. Expand
Different clusters of perfectionism in inpatients with anorexia nervosa and healthy controls.
In AN, anxiety and depression severity varied across clusters according to perfectionism, but patients' baseline perfectionism was unrelated to hospitalization outcome, and hospitalization outcomes were unrelated to inpatients' baselineperfectism. Expand
Development and validation of the Premorbid Childhood Traits Questionnaire (PCT-Q) in eating disorders.
Findings support the possibility that premorbid traits contribute to a risk to develop an ED in some individuals. Expand
Epigenetics in eating disorders: a systematic review
A systematic review of the current body of evidence on epigenetic factors in eating disorders to inform future directions in this area and encourages the scientific community to apply methodologically sound approaches using genome-wide designs including epigenome-wide association studies (EWAS), to increase sample sizes, and to broaden the focus to include all eating disorder types. Expand
A longitudinal study of eating behaviours in childhood and later eating disorder behaviours and diagnoses
The results suggest continuities of eating behaviours into eating disorders from early life to adolescence remain to be determined whether childhood eating behaviours are an early manifestation of a specific phenotype or whether the mechanisms underlying this continuity are more complex. Expand
The Western diet: a blind spot of eating disorder research?—a narrative review and recommendations for treatment and research
A paradigm shift is needed in the conceptual framework by which the vulnerability to, and maintenance of, different eating disorders may be understood, by integrating recent knowledge of the individual metabolic responses to modern highly processed foods into existing psychological models. Expand
Which Symptoms, Complaints and Complications of the Gastrointestinal Tract Occur in Patients With Eating Disorders? A Systematic Review and Quantitative Analysis
GI symptoms and impaired gastric transit times were frequent features of EDs with specific differences found for the ED types, including a variety of serious complications such as gastric dilatation. Expand
Salivary opiorphin levels in anorexia nervosa: A case–control study
Measurement of salivary opiorphin levels cannot be used as a marker of AN but may allow new perspectives in monitoring AN in its early stages. Expand


Monozygotic twin pairs discordant for lifetime anorexia nervosa: An exploratory investigation
Although there is an increasing understanding of the impact of genetic factors on the development of anorexia nervosa (AN), clear identification of environmental risk factors remains unclear. UsingExpand
Shared Temperament Risk Factors for Anorexia Nervosa: A Twin Study
The evidence overall supports the suggestion that anorexia nervosa may represent the expression of a common underlying familial liability to a temperament style that reflects a striving for perfectionism, a need for order, and a sensitivity to praise and reward. Expand
A comparison of early family life events amongst monozygotic twin women with lifetime anorexia nervosa, bulimia nervosa, or major depression.
While some overlap among early life events was indicated, there was evidence to support some degree of nonoverlap among life events associated with Anorexia nervosa, BN, and MD. Expand
Twin studies of adult psychiatric and substance dependence disorders: are they biased by differences in the environmental experiences of monozygotic and dizygotic twins in childhood and adolescence?
Differential environmental experiences of MZ and DZ twins in childhood and adolescence are unlikely to represent a substantial bias in twin studies of most major psychiatric and substance dependence disorders but may influence twin similarity for the initiation of substance use. Expand
Rethinking twins and environments: possible social sources for assumed genetic influences in twin research.
Findings suggest that past twin studies could overstate the strength of genetic influences because some similarities in behavior among monozygotic compared to dizygotic twins stem from social influences. Expand
The Structure of Perfectionism: A Twin Study
These multivariate twin modeling results support conceptualizations of perfectionism as a multidimensional construct and suggest CM is the core feature of Perfectionism with DA and PS serving as indicators of CM. Expand
Does intra‐uterine growth discordance predict differential risk for adult psychiatric disorder in a population‐based sample of monozygotic twins?
Whether intra‐pair differences in birth weight predicts discordance for adult psychiatric disorders in 527 female monozygotic twin pairs from a population‐based twin registry is examined. Expand
Twin studies of eating disorders: a review.
It is not possible to draw firm conclusions regarding the precise contribution of genetic and environmental factors to anorexia nervosa, but twin studies confirm that bulimia nervosa is familial and reveal significant contributions of additive genetic effects and of unique environmental factors in liability to bulimic nervosa. Expand
Twin studies and the etiology of eating disorders.
The findings of the major twin studies of eating disorders are inconsistent and difficult to interpret, with estimates for the heritability of liability to bulimia nervosa ranging from 0% to 83%, and from0% to 70% for anorexia nervosa. Expand
Differential heritability of eating attitudes and behaviors in prepubertal versus pubertal twins.
Findings suggest that a portion of the genetic influence on eating pathology may become activated during puberty, similar to the 17-year-old twins' influence. Expand
