Dynamic relation between physical activity and sleep in old age – the role of self-regulation, stress and dyadic factors

老年人的健康行为，如身体活动和睡眠，对健康做出了重大贡献。这两种健康行为对各种健康结果都有有益的影响，是关键的公共卫生优先事项。然而，身体活动以及睡眠质量和数量随着年龄的增长而下降。有第一个证据表明身体活动和睡眠之间存在相互关系。然而，到目前为止，联系身体活动和睡眠的健康和神经心理机制还没有得到很好的理解。根据Hagger的模型，应该研究自我调节和压力是否介导了睡眠和身体活动之间的关系。 除了这些个人因素外，最近的研究还概述了（婚姻）伴侣对健康行为的重要作用。Hoppmann和Gerstorf的一个概念模型描述了配偶之间的相互关系，如共同的目标或合作解决问题，如何与健康行为相关，并最终影响长期的健康结果。我的目标是将这种二元方法纳入自我调节理论。激励和缓冲效应以及二元因素的潜在不利因素都应该被调查。为了在方法上加强以前的研究，身体活动和睡眠之间的时间联系应使用生态瞬时评估（EMA）进行检查，因为它可以研究详细的日常生活过程。上述研究问题应在Hoppmann教授的关联生活研究中进行检查（我提议的东道主是加拿大温哥华的不列颠哥伦比亚省大学）。这项研究提供了一个独特的机会，分析EMA数据在一个二元设计与双方的婚姻partners.The拟议的研究将进一步了解身体活动和睡眠之间的动态关系。在未来，对身体活动或睡眠的干预可能会受益，同时考虑到其他行为，并解决自我调节，压力和二元因素。

Health behaviors among older adults such as physical activity and sleep make major contribution towards health. Both health behaviors have beneficial effects on various health outcomes and are key public health priorities. However, physical activity as well as sleep quality and quantity decline with age. There is first evidence for a reciprocal relationship between physical activity and sleep. Yet, so far health- and neuro-psychological mechanisms linking physical activity and sleep are not well understood. According to a model by Hagger, it should be investigated if self-regulation and stress mediate the relationship between sleep and physical activity. Beside these individual factors, recent research has outlined the important role of (marital) partners on health behavior. A conceptual model by Hoppmann and Gerstorf describes how spousal interrelations like shared goals or collaborative problem solving are related to health behaviors and ultimately influence long-term health outcomes. My aim is to include this dyadic approach in self-regulation theory. Motivating and buffering effects but also potential downsides of dyadic factors should be investigated.To enhance previous research methodologically, the temporal link between physical activity and sleep should be examined using Ecological Momentary Assessment (EMA) as it allows studying detailed daily-life processes.The research questions described above should be examined within the Linked Lives Study by Prof. Hoppmann (my proposed host at the University of British Columbia at Vancouver, Canada). The study offers the unique opportunity to analyse EMA data in a dyadic design with both marital partners.The proposed research will further the understanding of the dynamic relations between physical activity and sleep. In the future, interventions on either physical activity or sleep might profit taking into account the other behavior as well and address self-regulation, stress and dyadic factors.
