Summary
Individuals with personality disorders (PDs) face a higher risk of obesity. These patients also experience less success in traditional weight-loss programs, highlighting the need for tailored interventions.
Area of Science:
- Psychiatry
- Obesity Research
- Clinical Psychology
Background:
- Personality traits are linked to obesity and weight management.
- Research on the association between personality disorders (PDs) and obesity is limited.
Purpose of the Study:
- To review and critically evaluate studies on PDs and obesity.
- To assess the predictive value of PDs for obesity development.
- To examine the effectiveness of weight reduction treatments in patients with PDs.
Main Methods:
- Comprehensive literature search of PubMed and PsycINFO databases.
- Inclusion of 68 studies published over the last 35 years.
- Critical evaluation of study results.
Main Results:
- Adults with any PD have an increased risk of obesity.
- Specific PDs (avoidant, antisocial, paranoid, schizotypal) are associated with higher obesity risk in women.
- PDs, particularly borderline and avoidant PD, frequently co-occur with binge-eating disorder.
- Patients with PDs demonstrate poorer outcomes in conservative weight-loss programs compared to those without PDs.
Conclusions:
- Individuals with PDs have a greater susceptibility to obesity.
- Comorbid PDs in obesity treatment necessitate specialized care approaches.
- Prevention and treatment strategies should be adapted for patients with co-occurring PDs.
