Social relationships are reliably related to rates of morbidity and mortality. One pathway by which social relationships may influence health is via the impact of relationship quality on cardiovascular reactivity during social interactions.
This study examined the effects of the quality of a friendship on cardiovascular reactivity when speaking about positive or negative life events with an ambivalent or supportive friend. To examine this, 107 healthy male and female adults (and their same-sex friend) were recruited.
Results revealed that participants exhibited the greatest levels of systolic blood pressure reactivity when discussing a negative event with an ambivalent friend compared to a supportive friend. We also found higher resting levels of heart rate and lower respiratory sinus arrhythmia among those who brought in ambivalent friends than those who brought in supportive friends.
Individuals may not be able to fully relax in the presence of ambivalent friends and may not benefit from support during stress. This research may help clarify the health-related consequences of differing types of social relationships.
社会关系与发病率和死亡率密切相关。社会关系影响健康的一种途径是通过关系质量对社交互动中心血管反应性的影响。
本研究考察了在与矛盾型或支持型朋友谈论积极或消极生活事件时，友谊质量对心血管反应性的影响。为了进行此项研究，招募了107名健康的成年男性和女性（以及他们的同性朋友）。
结果显示，与支持型朋友相比，参与者在与矛盾型朋友讨论负面事件时，收缩压反应性水平最高。我们还发现，带来矛盾型朋友的人比带来支持型朋友的人静息心率更高，呼吸性窦性心律不齐更低。
在矛盾型朋友面前，个体可能无法完全放松，在压力期间可能无法从支持中受益。这项研究可能有助于阐明不同类型社会关系对健康的相关影响。
