ABSTRACT

Background: Heart rate variability (HRV) has been suggested as an indicator of capacity to adapt effectively to physiological or environmental challenges and of physical and psychological health in old age. Aims: The study assessed levels of high-frequency HRV (HF-HRV) among older adults in relation to positive and negative affect and the mediating role of positive and negative affect in the association between coping resources (perceived social support and sense of mastery) and HF-HRV.Method: Participants were 187 men and women in three assisted-living residences who were independent in activities of daily living (93.4% participation rate). The participants completed sense of mastery, multidimensional scale of perceived social support, and positive and negative affect questionnaires. HF-HRV was derived from electrocardiography data measured by a Holter monitoring device for 15 minutes.Results: The empirical model showed good fit indices indicating that higher HF-HRV was associated with lower negative affect, and negative affect mediated the association between perceived social support and HF-HRV. In addition, perceived social support and sense of mastery were associated with higher positive affect and lower negative affect.Conclusions: Although this was a cross-sectional study, it suggests that HF-HRV may be a link between affect and health in old age. It also suggests the importance of identification and intervention with older adults and their support systems to reduce negative affect.

摘要

背景：心率变异性 (HRV) 已被建议作为有效适应生理或环境挑战的能力以及老年人身体和心理健康的指标。目的：该研究评估了老年人的高频 HRV (HF-HRV) 水平与积极和消极情绪的关系，以及积极和消极情绪在应对资源（感知的社会支持和掌控感）之间的关联中的中介作用和 HF-HRV。方法：参与者是三个辅助生活住宅的 187 名男性和女性，他们独立进行日常生活活动（93.4% 的参与率）。参与者完成了掌握感、感知社会支持的多维量表以及积极和消极影响问卷。HF-HRV 来自于由 Holter 监测设备测量 15 分钟的心电图数据。结果：经验模型显示出良好的拟合指数，表明较高的 HF-HRV 与较低的负面情绪相关，而负面情绪介导了感知社会支持之间的关联和 HF-HRV。此外，感知到的社会支持和掌控感与较高的积极情绪和较低的消极情绪相关。结论：虽然这是一项横断面研究，但它表明HF-HRV可能是老年情绪与健康之间的联系。它还表明识别和干预老年人及其支持系统以减少负面影响的重要性。实证模型显示了良好的拟合指数，表明较高的 HF-HRV 与较低的负面情绪相关，而负面情绪介导了感知社会支持与 HF-HRV 之间的关联。此外，感知到的社会支持和掌控感与较高的积极情绪和较低的消极情绪相关。结论：虽然这是一项横断面研究，但它表明HF-HRV可能是老年情绪与健康之间的联系。它还表明识别和干预老年人及其支持系统以减少负面影响的重要性。实证模型显示出良好的拟合指数，表明较高的 HF-HRV 与较低的负面情绪相关，而负面情绪介导了感知社会支持与 HF-HRV 之间的关联。此外，感知到的社会支持和掌控感与较高的积极情绪和较低的消极情绪相关。结论：虽然这是一项横断面研究，但它表明HF-HRV可能是老年情绪与健康之间的联系。它还表明识别和干预老年人及其支持系统以减少负面影响的重要性。尽管这是一项横断面研究，但它表明 HF-HRV 可能是老年人情感与健康之间的联系。它还表明识别和干预老年人及其支持系统以减少负面影响的重要性。尽管这是一项横断面研究，但它表明 HF-HRV 可能是老年人情感与健康之间的联系。它还表明识别和干预老年人及其支持系统以减少负面影响的重要性。
