Abstract

BACKGROUND

Sarcopenia is a leading cause of functional decline, loss of independence, premature mortality, and frailty in older adults. Reducing and breaking up sedentary behaviour is associated with positive sarcopenia and frailty outcomes. This study aimed to explore the acceptability, engagement and experiences of a remotely delivered sedentary behaviour intervention to improve sarcopenia and independent living in older adults with frailty.

METHODS

This was a mixed-methods study. In-depth qualitative semi-structed interviews were conducted with a subset (N = 15) of participants with frailty (aged 74 ± 6 years) who had participated in the Frail-LESS (LEss Sitting and Sarcopenia in Frail older adults) intervention aimed at reducing sedentary behaviour. The interviews explored acceptability of the intervention overall and its individual components (a psychoeducation workbook, wrist-worn activity tracker, health coaching, online peer support and tailored feedback on sitting, standing and stepping). Process evaluation questionnaires with closed and scaled questions explored intervention engagement, fidelity and experiences.

RESULTS

Overall acceptability of the intervention was good with most participants perceiving the intervention to have supported them in reducing and/or breaking up their sedentary behaviour. The wrist-worn activity tracker and health coaching appeared to be the most acceptable and useful components, with high levels of engagement. There was attendance at 104 of 150 health coaching sessions offered and 92% of participants reported using the wrist-worn activity tracker. There was a mixed response regarding acceptability of, and engagement with, the psychoeducation workbook, tailored feedback, and online peer support.

CONCLUSIONS

The Frail-LESS intervention had good levels of acceptability and engagement for some components. The findings of the study can inform modifications to the intervention to optimise acceptability and engagement in a future definitive randomised controlled trial.

TRIAL REGISTRATION

The trial was registered with ISRCTN (number ISRCTN17158017).

摘要

背景

肌少症是导致老年人功能下降、丧失独立性、早亡和虚弱的主要原因。减少并打破久坐行为与肌少症和虚弱的积极结果相关。本研究旨在探讨远程提供的久坐行为干预措施在改善虚弱老年人肌少症和独立生活方面的可接受性、参与度和体验。

方法

这是一项混合方法研究。我们对 Frail-LESS（减少虚弱老年人久坐和肌少症）干预试验中参与减少久坐行为的一部分虚弱（年龄 74 ± 6 岁）参与者（n=15）进行了深入的定性半结构式访谈。这些访谈总体上探讨了干预措施的可接受性及其各个组成部分（心理教育手册、腕戴活动追踪器、健康指导、在线同伴支持以及对坐、站和走的个性化反馈）。使用封闭式和量表式问题的过程评估问卷探讨了干预措施的参与度、忠实度和体验。

结果

干预措施的总体可接受性良好，大多数参与者认为干预措施支持他们减少和/或打破久坐行为。腕戴活动追踪器和健康指导似乎是最受欢迎和最有用的组成部分，参与度很高。提供的 150 次健康指导课程中有 104 次有人参加，92%的参与者报告使用腕戴活动追踪器。对于心理教育手册、个性化反馈和在线同伴支持的可接受性和参与度，参与者的反应不一。
