背景资料：风险厌恶与年轻人和中年人的许多重要决定有关，但风险厌恶与决策之间的联系尚未得到很好的研究，老年人面临着他们生活中一些最重要的决定。方法：使用来自拉什记忆和衰老项目（一项正在进行的老龄化纵向流行病学研究）的606名社区居住老年人的数据，我们研究了风险规避与决策的关系。风险厌恶是用标准的行为经济学问题来衡量的，参与者被要求在一定的金钱支付（15美元）与赌博之间做出选择，在赌博中他们可以获得超过15美元或一无所获;潜在的赌博收益范围从20美元到300美元不等，收益金额随问题随机变化。决策是衡量使用12个项目版本的决策能力评估工具。调查结果：在一个调整了年龄、性别、教育和收入的线性回归模型中，更大的风险厌恶与更差的决策相关[估计值=-1.03，标准误（SE）= 0.35，p = 0.003]。随后的分析表明，在调整了整体认知功能以及执行和非执行认知能力之后，风险厌恶与决策的关联仍然存在。结论：与对年轻人的研究结果类似，风险规避与老年人面临无数复杂和有影响力的决定的决策能力较差有关。
Background: Risk aversion is associated with many important decisions among younger and middle aged persons, but the association of risk aversion with decision making has not been well studied among older persons who face some of the most significant decisions of their lives. Method: Using data from 606 community-dwelling older persons without dementia from the Rush Memory and Aging Project, an ongoing longitudinal epidemiologic study of aging, we examined the association of risk aversion with decision making. Risk aversion was measured using standard behavioral economics questions in which participants were asked to choose between a certain monetary payment ($15) versus a gamble in which they could gain more than $15 or gain nothing; potential gamble gains ranged from $20 to $300 with the gain amounts varied randomly over questions. Decision making was measured using a 12 item version of the Decision Making Competence Assessment Tool. Findings: In a linear regression model adjusted for age, sex, education, and income, greater risk aversion was associated with poorer decision making [estimate = −1.03, standard error (SE) = 0.35, p = 0.003]. Subsequent analyses showed that the association of risk aversion with decision making persisted after adjustment for global cognitive function as well as executive and non-executive cognitive abilities. Conclusion: Similar to findings from studies of younger persons, risk aversion is associated with poorer decision making among older persons who face a myriad of complex and influential decisions.
