【Background and purpose】Personality traits, unique to individual behaviors, have been linked to chronic diseases, including diabetes. This study investigates the relationship between personality traits and diabetes among working-age Japanese adults.
【Methods】In this cross-sectional study, we assessed the personality traits (conscientiousness, neuroticism, extraversion, openness, and agreeableness) using the Japanese version of the Ten Item Personality Inventory (TIPI-J) in a cohort of working-age Japanese adults with diabetes. Multiple logistic regression analysis was performed to estimate the effects. The primary outcome was blood glucose control status, determined by HbA1c levels, with poor control defined as an HbA1c level of 7.0% or higher. Age, gender, body mass index (BMI), and step count were adjusted as covariates, with personality traits as independent variables in diabetes management status.
【Results】Among the 1,568 participants included, conscientiousness was a significant predictor of blood glucose management status (odds ratio = 0.92, 95% CI: 0.85–0.99), after adjusting for age, sex, step counts, and BMI. No other personality trait variables significantly impacted blood glucose management.
【Conclusions】Conscientiousness emerged as a crucial personality trait for blood glucose management in working-age Japanese adults with diabetes.
