2型糖尿病患者におけるパーソナリティと肥満の関係

抄録

Objective: This study aimed to assess the relationship between personality and obesity in patients with type 2 diabetes.

Research Design and Methods: Patients with type 2 diabetes (n=62) completed the Maudsley's Personality Inventory (MPI) questionnaire to assess their tendency for extraversion (E) and neuroticism (N) and their tendency to lie (L). Patients were categorized into three groups per measure and their clinical characteristics were compared.

Results: Half of the patients demonstrated a combination of high E scores and low N scores. An inverse correlation between body mass index (BMI) and E and N scores was observed, but was not significant. Patients in the highest BMI quartile (BMI ≥34.3 kg/m²) had the highest N scores compared to those in the lowest BMI quartile (BMI ≤22.7 kg/m²) (p<0.05). The same correlation was observed for leptin levels and N scores, which was significant. There were no differences in E, N and L scores across the adiponectin or alanine transaminase quartiles.

Conclusion: Obese Japanese patients with type 2 diabetes may be more introverted and neurotic than those with lower BMIs. Greater attention should be paid to treatment individualization for these diabetic patients.
