背景和目的老年人经历较少的负面互动，并报告较少的压力，以应对人际关系紧张。然而，人们对日常社会交往对生物应激反应的影响知之甚少。我们评估了日常积极和消极的相互作用和下丘脑-垂体-肾上腺轴的2个关键生物指标：唾液皮质醇和硫酸脱氢表雄酮（DHEA-S）之间的联系。我们还考虑了年龄的调节作用。Research Design and MethodsParticipants包括一个随机样本的93个人年龄在40-95谁完成了14天的日常日记采访，并提供唾液样本在4的那些days.ResultsThree-level分段模型显示，个人有更高的持续DHEA-S水平的天后，报告更积极的互动。年轻的老年人（60-79岁）在他们有更多负面相互作用的日子里比最年长的老年人（80岁及以上）有更低的整体DHEA-S。与中年人（40-59岁）相比，年龄最大的老年人在报告更多负面相互作用后的几天内表现出DHEA-S的平稳下降。日常社会交往没有显着相关cortisol.Discussion和implicationsStrategies，以增加积极的互动可能有助于建立生理弹性的压力，特别是在中年和中老年成年人。
Background and ObjectivesOlder people experience fewer negative interactions and report less stress in response to interpersonal tensions. Less is known, however, about the implications of daily social interactions for biological stress responses. We evaluated links between daily positive and negative interactions and 2 key biomeasures of the hypothalamic–pituitary–adrenal axis: salivary cortisol and dehydroepiandrosterone sulfate (DHEA-S). We also considered the moderating effects of age.Research Design and MethodsParticipants included a random sample of 93 individuals aged 40–95 who completed 14 days of daily diary interviews and provided saliva samples during 4 of those days.ResultsThree-level piecewise models showed that individuals had higher sustained DHEA-S levels on days after reporting more positive interactions. Young-old adults (60–79) had lower overall DHEA-S on days when they had more negative interactions than oldest-old adults (80 and older). Oldest-old adults showed a flatter decline in DHEA-S on days after they reported more negative interactions compared to midlife adults (40–59). Daily social interactions were not significantly associated with cortisol.Discussion and ImplicationsStrategies to increase positive interactions may help to build physiological resilience to stress, particularly among midlife and young-old adults.
