研究目的：

Project Objectives (a maximum of 800 words in total for the project objectives) [Please list the objectives in point form] 1. To evaluate the efficacy of mindfulness-based training in enhancing gut microbiome diversity and beneficial bacteria in older adults with chronic stress. 2. To explore whether gut microbiota differences between MBOA and HEC are mediated by changes in mindfulness levels and moderated by perceived stress, depressive and anxiety symptoms, diet, sleep, and loneliness. Key issues and/or problems being addressed: Previous studies have shown that chronic stress is an important factor affecting gut microbiota composition and diversity, especially in older adults. Therefore, interventions designed to enhance the gut microbiota is most needed in older adults experiencing chronic stress. Mindfulness-based intervention is one of the candidates. Based on past studies, mindfulness-based interventions can effectively treat common mental health problems, including depression, chronic stress, and anxiety. However, there is limited evidence on its efficacy in enhancing gut microbiota and no randomized controlled studies have explored how it affects gut microbiota when compared to an active control. Therefore, this randomized control trial is designed to provide direct evidence for the impact of mindfulness-based interventions on gut microbiota in older adults. In addition, the moderating effects of perceived stress, depressive and anxiety symptoms, diet, sleep and loneliness will be explored, which will provide insight for the clinical application of mindfulness-based intervention.
