Relationships among personality traits, metabolic syndrome and metabolic syndrome scores : The Kakegawa cohort study

Objective: Metabolic syndrome and the presence of metabolic syndrome components are risk factors for cardiovascular disease (CVD). However, the association between personality traits and metabolic syndrome remains controversial, and few studies have been conducted in East Asian populations. Methods: We measured personality traits using the Japanese version of the Eysenck Personality Questionnaire (Revised Short Form) and five metabolic syndrome components-elevated waist circumference, elevated triglycerides, reduced high-density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose-in 1,322 participants aged 51.1±12.7 years old from Kakegawa city, Japan. Metabolic syndrome score (MS score) was defined as the number of metabolic syndrome components present, and metabolic syndrome as having an MS score of 3 or higher, in accordance with the American Heart Association/National Heart, Lung, and Blood Institute Scientific Statement. Results: Mean (± standard deviation) personality scores were higher in participants with (N=241) than without metabolic syndrome (N=1,081): 6.1±3.2 vs. 5.6±3.1 for “extraversion”, 3.0±1.6 vs. 2.8±1.6 for “psychoticism”, 6.7±2.5 vs. 6.1±2.7 for “lie”, respectively (all P<0.05). In multiple regression analyses adjusted for age, sex, education, income, smoking status, alcohol use, and family history of CVD and diabetes mellitus, only “extraversion” was associated with MS score (coefficient=0.12, P=0.0003). In multiple logistic regression analysis with the same adjustments, “extraversion” was also positively associated with metabolic syndrome (odds ratio = 1.13, 95% confidence interval = 0.97-1.31; P=0.1). Conclusions: Higher “extraversion” scores tended to be related to a higher prevalence of metabolic syndrome and higher MS scores.
