Introduction Older adults are the fastest growing and most sedentary group in society. With sedentary behaviour associated with negative health outcomes, reducing sedentary time may improve overall wellbeing. This single-arm mixed-method feasibility study explored the acceptability of an intervention to reduce sedentary behaviour in community-dwelling older adults aged ≥75 years. Methods Participants were recruited from the Community Ageing Research 75+ Study (CARE75+) cohort, with factors such as age, frailty status, living arrangements and levels of sedentariness being considered. The intervention consisted of an educational booklet including advice on how to reduce sedentary behaviour, a smartwatch with a sedentary reminder function, educational group sessions and follow up phone calls. The 9-week intervention was conducted from June–August 2023. Reach, uptake, adherence, and adverse events were recorded, and the acceptability of the intervention was explored through semi-structured exit interviews. Results Of the 39 eligible participants, 10 consented (5 M:5F) and had a mean age 84.3 years. The intervention had an uptake and reach of 25.6%, and retention of 100%. No falls, hospitalisations or deaths occurred, and three cases of mild irritation were reported which resolved during the study. 100% adherence was observed for the group sessions and follow-up phone calls, and 65% for self-monitoring. Qualitative data suggests that participants were receptive of the intervention according to the domains of the Theoretical Framework of Acceptability, and suggestions were provided on refining the intervention components. Conclusion Strategies to reduce sedentary behaviour were tested on a diverse sample of community-dwelling older adults in the oldest old age group, with varying levels of sedentary behaviour and frailty status. The presented strategies appear to be acceptable, appropriate, safe, and high levels of adherence were observed. Participant feedback will be used to refine the intervention.

2250 减少 75 ≥社区老年人久坐行为的干预措施的混合方法可行性研究


简介 老年人是社会上增长最快、最久坐不动的群体。由于久坐行为与负面健康结果相关，减少久坐时间可能会改善整体健康状况。这项单臂混合方法可行性研究探讨了减少 75 岁社区老年人久坐行为的干预措施的可接受性≥。方法 参与者是从社区老龄化研究 75+ 研究 （CARE75+） 队列中招募的，考虑了年龄、虚弱状况、生活安排和久坐程度等因素。干预措施包括一本教育小册子，其中包括有关如何减少久坐行为的建议、具有久坐提醒功能的智能手表、教育小组会议和后续电话。为期 9 周的干预于 2023 年 6 月至 8 月进行。记录了覆盖率、摄取、依从性和不良事件，并通过半结构化退出访谈探讨了干预的可接受性。结果 在 39 名符合条件的参与者中，10 名同意 （5 M：5F），平均年龄 84.3 岁。干预的接受率和覆盖率为 25.6%，保留率为 100%。没有发生跌倒、住院或死亡，并且报告了 3 例轻度刺激，这些刺激在研究期间得到解决。观察到小组会议和后续电话的依从性为 100%，自我监测的依从性为 65%。定性数据表明，根据可接受性理论框架的领域，参与者对干预的接受度很高，并提供了关于完善干预组成部分的建议。 结论 在最年长的老年人群中，对社区居住的老年人的不同样本进行了减少久坐行为的策略进行了测试，这些老年人具有不同程度的久坐行为和虚弱状态。所提出的策略似乎是可接受的、适当的、安全的，并且观察到高水平的依从性。参与者的反馈将用于改进干预。
