Daily stressor reactivity and profiles of physical health across adulthood

 描述(由申请人提供)：当前建议的目标是检查对日常应激源的情感(即情绪)反应是否与异位LOA相关，LOA是一种与发病率和死亡率增加相关的多系统生理功能指标。该项目还将确定老年人--由于他们的生理系统弹性较差--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的历史如何影响对日常应激源的情感反应性、年龄和变态负荷之间的关系。从拟议的研究中获得的知识可能会揭示使人们面临更大风险的身体健康问题的因素，可能会确定一条在以后的生活中出现健康差距的重要途径。

 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.
