Personality Traits and Cancer Risk and Survival Based on Finnish and Swedish Registry Data

摘要: Personality traits have been studied extensively as risk and prognostic factors for cancer; however, the association remains unclear. This prospective, population-based cohort study comprised 59,548 Swedish (1974-1999) Finnish (1976-2004) participants who completed a questionnaire eliciting information Eysenck Inventory on health behavior at baseline. To analyze of personality extraversion neuroticism with cancer, authors identified 4,631 cancer cases maximum 30 years follow-up. assess survival among participants, they 2,733 and, later, 1,548 deaths 29 Hazard ratios were estimated by treating scales continuous variables are presented per one increase in score each scale. In multivariate analyses, not significantly associated cancers all sites (extraversion: hazard ratio = 0.99, 95% confidence interval: 0.98, 1.01; neuroticism: 1.00, 1.02). Results showed no significant between these death after sites, do support hypothesis that direct or cancer.
