Falls can have catastrophic consequences, especially for older adults. This study examined whether personality traits predict the incidence of falls in older age.
Participants were older adults aged from 65 to 99 years (N = 4,759) drawn from the Health and Retirement Study. Personality traits and demographic factors were assessed at baseline. Falls were tracked for up to 11 years.
Over the follow-up period, 2,811 individuals reported falls. Cox regression analyses that included demographic covariates indicated that lower conscientiousness and higher neuroticism increased the risk of falling. Disease burden, depressive symptoms, and physical inactivity mediated the associations between both traits and falls incidence, whereas smoking status and handgrip strength mediated the neuroticism-falls incidence association.
This study provides new prospective evidence that personality predicts the incidence of falls in older adults and suggest that personality assessment may help identifying individuals at higher risk of falling.
跌倒可能会产生灾难性的后果，尤其是对老年人而言。本研究旨在探讨人格特质是否可以预测老年人跌倒的发生率。
参与者为年龄在 65 至 99 岁的老年人（N=4759），他们来自健康与退休研究。在基线时评估了人格特质和人口统计学因素。对跌倒情况进行了长达 11 年的跟踪。
在随访期间，有 2811 人报告了跌倒。包括人口统计学协变量的 Cox 回归分析表明，较低的尽责性和较高的神经质会增加跌倒的风险。疾病负担、抑郁症状和身体活动不足会调节这两种特质与跌倒发生率之间的关系，而吸烟状况和握力会调节神经质与跌倒发生率之间的关系。
本研究提供了新的前瞻性证据，表明人格可以预测老年人跌倒的发生率，并提示人格评估可能有助于识别跌倒风险较高的个体。
