The aim of this study was to investigate the relationship between personality traits, tobacco consumption, physical inactivity, obesity markers and metabolic components as cardiovascular risk factors (CVRFs). A total of 2543 participants from the general population (CoLaus|PsyCoLaus) had provided complete information on physical health and unhealthy behaviors and completed the Revised NEO Five-Factor Inventory. Our results show a strong cross-correlation between obesity markers and metabolic components suggesting that their combination could represent an important CVRF. Moreover, socio-demographic characteristics, tobacco consumption, and physical inactivity were associated with both obesity markers and metabolic components latent traits. The conscientiousness personality trait was significantly associated with obesity markers, but played a modest role. Indeed, higher conscientiousness was associated with lower level of obesity indicators. However, no link between personality and metabolic components were found. In sum, our data suggest that health related behaviours have more effect on the development of cardiovascular diseases than personality traits.
