Adoption and eating disorders: a high-risk group?
1Department of Psychiatry, University of Nottingham Medical School, Mapperley Hospital.
Summary
Adoptees were referred for eating disorders, including anorexia and bulimia, at a higher rate than the general population. These adoptees also experienced more behavioral issues and lower academic achievement.
Area of Science:
- Psychiatry
- Psychology
- Genetics
Background:
- Eating disorders, such as anorexia nervosa and bulimia nervosa, are complex conditions with multifactorial etiologies.
- Adoption is a unique life experience that may interact with genetic and environmental factors in the development of psychopathology.
Purpose of the Study:
- To investigate the prevalence of eating disorders among adoptees referred to a specialist eating disorder service.
- To compare behavioral and academic characteristics of adoptees with eating disorders to non-adoptee controls.
Main Methods:
- Retrospective case-note review of patients referred to the Maudsley Hospital between 1975 and 1985.
- Comparison of adoptee patients (n=18) with matched non-adoptee controls (n=18) based on year of birth.
- Analysis of demographic, clinical, and academic data.
Main Results:
- Adoptees constituted 3.8% of eating disorder referrals, significantly higher than the 1.5% adoption rate in the general population.
- Adoptees with eating disorders exhibited significantly greater behavioral disturbances and lower academic achievement compared to controls.
- Distinct precipitating factors were identified between the adoptee and non-adoptee groups.
Conclusions:
- Adoption may represent a risk factor for the development of eating disorders.
- Adoptees with eating disorders may present with a more complex clinical profile, including comorbid behavioral issues and academic difficulties.
- Further research is warranted to explore the interplay of genetic, environmental, and psychosocial factors in adoptees with eating disorders.
