Abstract

Studies have shown that higher levels of neuroticism are associated with greater risk of mortality. Yet what accounts for this association? One major theoretical position holds that persons higher in neuroticism engage in poorer health behaviors, such as smoking and excessive drinking, thus leading to earlier death. We tested this hypothesis using 30-year mortality in 1,788 men from the VA Normative Aging Study. Using proportional hazards (Cox) models we found that one health behavior, smoking, attenuated the effect of neuroticism on mortality by 40%. However, 60% remained unexplained, suggesting that the effects of other pathways (e.g., biological) also influence the relationship between neuroticism and mortality.

摘要

研究表明,神经质水平较高与更高的死亡风险相关。然而,这种关联的原因是什么呢?一个主要的理论观点认为,神经质水平较高的人健康行为较差,比如吸烟和过度饮酒,从而导致过早死亡。我们利用退伍军人规范老化研究中1788名男性的30年死亡率数据对这一假设进行了检验。使用比例风险(Cox)模型,我们发现一种健康行为,即吸烟,使神经质对死亡率的影响减弱了40%。然而,仍有60%无法解释,这表明其他途径(如生物学途径)的影响也在神经质与死亡率的关系中发挥作用。
