Shaky Income, Rising Angst? Income Volatility, Psychological Health, and Biological Aging

社会经济地位低的美国人比社会经济地位高的人健康状况差。了解 造成这些健康差距的原因是当今社会科学家面临的最重要的研究问题之一。 我建议调查造成这种健康差距的一个未被充分研究的原因：经济不确定性。收入 美国的波动性一直在上升，使其成为经济不确定性的一个日益重要的来源。92岁 %的美国人认为，拥有稳定的财务状况比收入阶梯上的提升更重要。收入 波动通常是不可预测的，这使得家庭无法预测并做好相应的准备。什么时候 收入下降，通常缺乏储蓄缓冲的低社会保障家庭可能难以维持收支平衡。 这种财务困境的前景可能会引起焦虑、担忧和压力。期待和期待 对令人厌恶和不确定的事件的担忧会引起焦虑和担忧，而不确定如何 如果事件发生可能造成压力，一个人可能会处理。根据非平衡加载框架，应力 增加心血管疾病和与年龄相关的代谢性疾病的风险，促进认知能力下降 和痴呆症，并加速细胞衰老。 我建议分析收入波动、心理健康和生理衰老之间的关系。 这个项目是跨学科的。我是一名经济学家，能够分析和衡量收入波动性。然而，我 缺乏对焦虑、担忧和压力进行概念化和测量的技能；缺乏理解生物过程的技能 通过这些不确定性和压力可能加速衰老；并知道如何使用生物标志物来测量 生理性衰老。K01将在两名杰出的导师和一名专家的指导下提供培训 顾问委员会--这会给我带来这样的技能。我的导师，教授。亚瑟·斯通和艾琳·克里明斯 在我需要培训的领域中有领先的专家，并有指导K01获奖者的经验。获奖名单 将为我制定这一议程提供有保障的时间。这项建议的具体目的是： 1)衡量收入波动的程度，并记录其在人口中的分布情况。 2)研究收入波动与心理健康的关系。 3)考察收入波动与生理老龄化之间的关系。 4)研究面临风险的人群，例如那些没有储蓄缓冲的人群。 我的长期职业目标是成为一名研究经济不确定性如何影响健康和老龄化的专家。我 我相信，这段持续的职业发展和培训将使我能够 独立的研究生涯，并成为该领域的领先研究人员。

Americans of low socioeconomic status (SES) are less healthy than those of high SES. Understanding the causes of these health disparities is one of the most important research questions social scientists face today. I propose to investigate an understudied cause of such health disparities: economic uncertainty. Income volatility has been rising in the US, making it an increasingly important source of economic uncertainty. For 92 percent of Americans, having financial stability is more important than moving up the income ladder. The income swings are often unpredictable, making them impossible for families to anticipate and prepare accordingly. When income dips, low-SES families, who often lack a cushion of savings, may struggle to make ends meet. The prospect of this scenario of financial distress may cause anxiety, worry, and stress. The anticipation and concern about an aversive and uncertain event can cause anxiety and worry while the uncertainty about how one might cope if the event occurs may cause stress. According to the allostatic load framework, the stress increases the risks of cardiovascular disease and of age-related metabolic diseases, promotes cognitive decline and dementia, and accelerates cellular aging. I propose to analyze the relationship between income volatility, psychological health, and physiological aging. This project is interdisciplinary. I am an economist and can analyse and measure income volatility. However, I lack the skills to conceptualize and measure anxiety, worry, and stress; to understand the biological processes through which uncertainty and stress may accelerate aging; and to know how to use biomarkers to measure physiological aging. The K01 will provide training – under the guidance of two outstanding mentors and an expert advisory committee – that will give me such skills. My mentors, Profs. Arthur Stone and Eileen Crimmins, are leading experts in the areas where I need training and have experience in mentoring K01 awardees. The award will provide protected time for me to develop this agenda. The specific aims of this proposal are to: 1) Measure the extent of income volatility and document how it is distributed in the population. 2) Investigate the relationship between income volatility and psychological health. 3) Examine the relationship between income volatility and physiological aging. 4) Study populations at risk, such as those without a buffer of savings. My long-term career goal is to become an expert on how economic uncertainty affects health and aging. I am confident that this sustained period of career development and training will enable me to launch an independent research career and emerge as a leading researcher in this area.
