Key result
In a Korean population, personality traits were significantly associated with BMI, with lower neuroticism predicting overweight in women (OR 0.912) and lower openness to experience predicting obesity.

Specific personality traits, including extraversion in men and neuroticism, openness, and agreeableness in women, are significantly associated with BMI and waist circumference in a Korean population.
Should not guide BMI screening or counseling; extends personality-BMI associations to Koreans but leaves causality and clinical utility open.
BACKGROUND: Overweight and obesity is a serious problem worldwide related to cardiovascular and other diseases. Personality traits are associated with the abnormal body mass indices (BMIs) indicative of overweight and obesity. However, the links between personality traits and BMI have been little studied in Korea. METHODS: We evaluated the association between personality traits and BMI in men and women using the rural Ansung and urban Ansan cohort from the Korean Genome Epidemiology Study, and the Kangbuk Samsung Hospital Cohort Study datasets. A shorter version of the original Revised Neuroticism-Extroversion-Openness Personality Inventory (NEO-PI-R) was used to measure the five-factor model of personality (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness). RESULTS: Data from a total of 1,495 men (mean age 60.0 ± 9.8 years; mean BMI 24.3 ± 3.0 kg/m2) and 2,547 women (mean age 47.0 ± 15.5 years; mean BMI 22.8 ± 3.4 kg/m2) were included in the analysis. Compared with the normal weight groups, overweight and obese men scored higher on openness to experience and lower on conscientiousness. Overweight and obese women scored lower on neuroticism and openness to experience and higher on agreeableness. Extraversion was positively associated with BMI in men (β=0.032, P<0.05). BMI and waist circumference were significantly increased in individuals who were less dutiful. In women, neuroticism was inversely associated with BMI (β=-0.026, P<0.05). Openness to experience was negatively, and agreeableness was positively, associated with BMI (openness to experience: β=-0.072, agreeableness β=0.068) and waist circumference (openness to experience: β=-0.202, agreeableness: β=0.227) (P<0.05). CONCLUSION: Personality traits were associated with underweight, overweight, and obesity in men and women. Increased understanding of the underlying factors contributing to this association will aid in the prevention and treatment of abnormal BMI.

Shim et al. (2014) conducted a cross-sectional in Overweight and obesity (n=4,042). Five-factor model personality traits vs. Normal weight was evaluated on Overweight in women (predicted by neuroticism) (OR 0.912, 95% CI 0.834-0.996, p=0.041). In a Korean population, personality traits were significantly associated with BMI, with lower neuroticism predicting overweight in women (OR 0.912) and lower openness to experience predicting obesity.
