To examine the association between marital interaction quality during daily life and subclinical cardiovascular disease (CVD). Studies have shown that marital status and quality of marriage are associated with cardiovascular health. However, little is known about the role of marital interaction quality during daily life in contributing to these effects.
The sample consisted of 281 healthy, employed middle-aged adults who were married or living with a partner in a marital-like relationship (mean age = 42.0 years, 88% white, 52% men). Marital interaction quality was assessed using hourly real-time ecological momentary assessments for 4 days, with participants rating their current or recent partner interactions on positive and negative characteristics (e.g., agreeableness and conflict). Carotid artery intima-medial thickness (IMT) was assessed using ultrasound imaging.
Adjusting for demographics, positive marital interaction was inversely associated with IMT (b = -0.02, F(1,275) = 9.18, p = .002), and negative marital interaction was positively associated with IMT (b = 0.02 F(1,275) = 10.29, p = .001). These associations were not accounted for by behavioral and biological CVD risk factors and were consistent across age, sex, race, and education. The associations were also independent of marital interaction frequency, nonmarital social interaction quality, and personality factors. Global reports of marital quality, in contrast, were not associated with IMT.
Marital quality as measured during real-time interactions between partners was associated with subclinical CVD in healthy middle-aged adults. This study supports the use of real-time social interaction assessment for characterizing links between social relationships and cardiovascular health.
探讨日常生活中的婚姻互动质量与亚临床心血管疾病（CVD）之间的关联。研究表明，婚姻状况和婚姻质量与心血管健康有关。然而，对于日常生活中的婚姻互动质量在这些影响中所起的作用知之甚少。
样本包括281名健康、有工作的中年成年人，他们已婚或与伴侣以类似婚姻的关系生活在一起（平均年龄 = 42.0岁，88%为白人，52%为男性）。婚姻互动质量通过连续4天每小时进行的实时生态瞬时评估来衡量，参与者对他们当前或最近与伴侣的互动在积极和消极特征（如随和性和冲突）方面进行评分。使用超声成像评估颈动脉内膜中层厚度（IMT）。
在对人口统计学因素进行调整后，积极的婚姻互动与IMT呈负相关（b = -0.02，F(1,275) = 9.18，p = .002），消极的婚姻互动与IMT呈正相关（b = 0.02，F(1,275) = 10.29，p = .001）。这些关联不能由行为和生物学的CVD危险因素来解释，并且在年龄、性别、种族和教育程度方面是一致的。这些关联也独立于婚姻互动频率、非婚姻社会互动质量和人格因素。相比之下，婚姻质量的总体报告与IMT无关。
伴侣之间实时互动中所衡量的婚姻质量与健康中年成年人的亚临床CVD有关。本研究支持使用实时社会互动评估来描述社会关系与心血管健康之间的联系。
