目的：心理社会应激与高发病率和死亡率相关。因此，对指示个体是否表现出适应性（即，压力缓冲和健康促进）或适应不良（即，压力升级和损害健康）的社会背景下的压力反应。由于心率变异性（HRV）已被认为是一个生物标志物的适应性行为在社会encountering.Methods的社会domains. To测试这一假设，静息状态的HRV和心理社会压力进行了评估，在83个健康的社区居住的个人（年龄：18-35岁），这可能是可能的，在HRV的个体间差异与个体间差异有关的压力在不同的社会domains.Methods。HRV来自自主呼吸和指令呼吸期间的心率记录，以评估HRV个体间差异与心理社会压力个体间差异之间可能相关性的稳健性。心理社会压力的确定与自我报告问卷评估压力在不同的社会domains.Results：一系列的分类和维度分析揭示了个体间差异的HRV和个体间差异的心理社会压力之间的关联：个体与高HRV报告较少的压力在社会生活中，但不是在家庭生活，工作生活或日常生活中，比个体与低HRV。基于这些发现，可以假设具有高HRV的个体比具有低HRV的个体经历更少的心理社会压力。虽然这种假设需要进一步的研究结果来证实，但它似乎与先前的研究结果一致，即高HRV的个体比低HRV的个体遭受更少的压力和压力相关疾病。
Objective: Psychosocial stress is associated with substantial morbidity and mortality. Accordingly, there is a growing interest in biomarkers that indicate whether individuals show adaptive (i.e., stress-buffering and health promoting) or maladaptive (i.e., stress-escalating and health-impairing) stress reactions in social contexts. As heart rate variability (HRV) has been suggested to be a biomarker of adaptive behavior during social encounters, it may be possible that inter-individual differences in HRV are associated with inter-individual differences regarding stress in distinct social domains.Methods: To test this hypothesis, resting state HRV and psychosocial stress was assessed in 83 healthy community-dwelling individuals (age: 18-35 years). HRV was derived from heart rate recordings during spontaneous and instructed breathing to assess the robustness of possible associations between inter-individual differences in HRV and inter-individual differences in psychosocial stress. Psychosocial stress was determined with a self-report questionnaire assessing stress in distinct social domains.Results: A series of categorical and dimensional analyses revealed an association between inter-individual differences in HRV and inter-individual differences in psychosocial stress: Individuals with high HRV reported less stress in social life, but not in family life, work life or everyday life, than individuals with low HRV.Conclusions: On basis of these findings, it may be assumed that individuals with high HRV experience less psychosocial stress than individuals with low HRV. Although such an assumption needs to be corroborated by further findings, it seems to be consistent with previous findings showing that individuals with high HRV suffer less from stress and stress-related disorders than individuals with low HRV.
