Daily stressor reactivity and profiles of physical health across adulthood

 描述（由申请人提供）：当前提案的目标是检查情感（即，情绪）对日常紧张性刺激的反应性与非稳态LOA相关，非稳态LOA是与发病率和死亡率增加相关的生理功能的多系统指数。这个项目还将确定老年人由于他们的生理系统弹性较低是否比年轻人更容易受到日常压力的不利影响。最后，我们将确定慢性应激源暴露史如何影响日常应激源的情感反应、年龄和非稳态负荷之间的关联。从拟议的研究中获得的知识可以揭示使人们面临身体健康问题风险增加的因素，可能会确定一个重要的途径，通过这个途径，健康差异在以后的生活中出现。

 DESCRIPTION (provided by applicant): The goal of the current proposal is to examine whether affective (i.e., emotional) reactivity to daily stressors is associated with allostatic loa, a multi-system index of physiological function that is associated with increased morbidity and mortality. This project will also determine whether older adults-by virtue of their less resilient physiological systems-are more adversely affected by daily stressors than are their younger counterparts. Finally, we will determine how history of chronic stressor exposure may influence the associations between affective reactivity to daily stressors, age, and allostatic load. Knowledge gained from the proposed research could reveal factors that place people at increased risk for debilitating physical health problems, potentially identifying an important pathway through which health disparities emerge in later life.
