Personality was measured with the Big Five Inventory-Short, and behaviors were assessed via seven-day electronic dietary records, plus data on BMI, physical activity, and smoking. Exploratory factor analysis identified two patterns of food consumption. Higher conscientiousness was significantly associated with a healthier lifestyle, indicated by higher consumption of vegetables, wholegrain products, fruits, and nuts (adjusted beta 0.16, 95%CI 0.06 to 0.26, p = 0.0015) and lower cigarette smoking (adjusted odds ratio 0.84, 95%CI 0.75 to 0.94, p = 0.0020). Associations with physical activity and BMI were insignificant. The study is limited by its secondary analysis of a database, a relatively small sample size for detecting weak associations, and the use of a shortened personality questionnaire. Results suggest that conscientiousness predisposes to healthier habits even under severe stress, indicating potential targets for lifestyle interventions.
