Relationships between obesity, bipolar spectrum features, and personality traits: a case-control study

Area of Science:

• Psychiatry
• Clinical Psychology
• Obesity Research

Background:

• Growing research links obesity with mental health disorders.
• Individuals with obesity often exhibit distinct personality traits.
• Obesity may increase susceptibility to bipolar spectrum disorders.

Purpose of the Study:

• To investigate the association between obesity, bipolarity features, and personality traits.
• To identify specific personality profiles in obese individuals with bipolarity.
• To understand the interplay between obesity, mood disorders, and personality.

Main Methods:

• A nested case-control study design was employed.
• 90 obese patients and 70 healthy controls participated.
• Bipolarity assessed using the Mood Disorder Questionnaire (MDQ); personality traits via NEO-Five Factor Inventory (NEO-FFI).

Main Results:

• Obese patients showed higher prevalence of bipolarity features (MDQ scores).
• Obese individuals scored lower on openness to experience (NEO-FFI).
• In obese patients, bipolarity correlated positively with neuroticism and negatively with agreeableness and conscientiousness.

Conclusions:

• Obesity is associated with a unique profile of bipolarity and personality traits (high neuroticism, low conscientiousness, low agreeableness).
• These findings suggest specific considerations for managing obese patients with bipolarity.
• Understanding these links can inform tailored pharmacological and psychological interventions.
