Summary

Anorexia nervosa disproportionately affects higher social classes, with earlier onset in these groups. Sociocultural factors, not referral bias, likely explain this social class distribution in patients.

Area of Science:

  • Psychiatry
  • Sociology
  • Public Health

Background:

  • Anorexia nervosa (AN) is a complex eating disorder with potential links to socioeconomic factors.
  • Understanding the social class distribution of AN is crucial for targeted prevention and intervention strategies.

Purpose of the Study:

  • To analyze the social class status of female patients with anorexia nervosa over 33 years.
  • To investigate potential differences in clinical features across social classes.

Main Methods:

  • Retrospective survey of a national specialist center's anorexia nervosa patient database.
  • Social class determined by father's occupation (UK Registrar General's classification).
  • Statistical analysis included univariate and ordinal logistic regression.

Main Results:

  • Consistently higher representation of patients from social classes 1 and 2.
  • Similar clinical features (low body weight, binge eating, purging) across social classes.
  • Earlier onset of dieting and disorder in higher social classes.
  • Slight increase in lower social class representation over time, challenging referral bias claims.

Conclusions:

  • The social class bias in anorexia nervosa likely stems from sociocultural influences.
  • AN may arise as an avoidant response to conflicts between family values and adolescent development within specific social classes.
