Area of Science:

  • Psychiatry and Public Health
  • Epidemiology of Mental Health and Body Weight

Background:

  • Personality disorders (PDs) are persistent psychiatric conditions with early onset, stemming from genetic and environmental factors, leading to significant individual dysfunction.
  • Conceptual links exist between PDs and body weight, though the relationship's direction may vary by PD type.

Purpose of the Study:

  • To investigate the impact of Axis II personality disorders on body weight, specifically body mass index (BMI) and obesity.
  • To differentiate the effects of various PDs on body weight and examine gender-specific associations.

Main Methods:

  • Analysis of data from Wave II of the National Epidemiological Survey of Alcohol and Related Conditions (NESARC).
  • Measurement of body weight using body mass index (BMI) and a dichotomous obesity indicator (BMI≥30).
  • Application of unconditional quantile regressions to explore the gradient of PD effects across the BMI spectrum.

Main Results:

  • Women with PDs exhibited significantly higher BMI and increased likelihood of obesity compared to women without PDs.
  • Statistically significant or economically meaningful effects of PDs on body weight were minimal in men.
  • Paranoid, schizotypal, and avoidant PDs were most strongly associated with adverse effects on women's body weight; dependent PD showed a potential protective effect in men.
  • Quantile regressions revealed a positive gradient, indicating greater effects of PDs on BMI at higher weight levels.

Conclusions:

  • Axis II personality disorders are significantly associated with increased body weight and obesity risk, particularly in women.
  • Specific PDs have differential impacts on body weight, with some potentially offering protection.
  • The findings underscore the importance of considering PDs in the management of obesity and weight-related health issues, especially for women.
