Facets of conscientiousness and objective markers of health status

Objective: To examine the association between six facets of conscientiousness (self-control, order, industriousness, traditionalism, virtue, responsibility) and objective markers of health status, including adiposity, blood markers and physical performance. Design: Cross-sectional analysis of participants from the health and retirement study (N = 12,188). Main Outcome Measures: Adiposity (body mass index, waist circumference), blood markers (A1c, HDL cholesterol, total cholesterol, cystatin c, c-reactive protein) and physical performance (lung function, grip strength, walking speed). Results: Four of the six facets of conscientiousness were associated with nearly all of the health markers: Self-control, organisation, industriousness and responsibility were related to lower adiposity, healthier metabolic, cardiovascular and inflammatory markers, and better performance on physical assessments. Traditionalism and virtue had fewer associations with these objective markers. Conclusion: This research took a facet-level approach to the association between conscientiousness and objective markers of health status. This research builds on models of conscientiousness and health to suggest that, in addition to health-risk behaviours, facets of conscientiousness are associated with more favourable biomedical markers of health status. © 2018 Informa UK Limited, trading as Taylor & Francis Group
