BACKGROUND Older adults spend up to 23 h daily sitting or lying while in hospital. Sedentary behaviour (SB) within a hospital setting is often associated with poor health outcomes including physical and cognitive decline, reduced quality of life and death as well as hospital readmissions. Conversely, replacing SB with mild to moderate levels of physical activity such as walking can significantly reduce hospital readmission risk by 30 days. Given the potentially harmful effects of SB in hospitalised older adults, it is vital to identify current literature by broadly exploring different aspects of SB among older people in hospital. The overall aim of this scoping review is to produce a literature map of current evidence on key domains of sedentary behaviour in hospitalised older people. METHOD A search for relevant publications will be undertaken in Pedro, MEDLINE Ovid, Cochrane, Scopus, Cumulative Index to Nursing and Allied Health Literature, PsychInfo, Embase, Ageline, Joanna Briggs Institute (JBI) and clinical trials registries. Publications in English and those where the author can provide the full text in English will be included. Studies conducted in hospitals (including in-patient rehabilitation facilities) or acute and subacute care settings and in people aged ≥ 65 will be included. A three-stage method will be used to identify relevant articles, consisting of database search using keywords, keywords and index words across all databases, and reference searching. Articles will be selected following screening of titles/abstracts succeeded by a full-text appraisal utilising a standardised selection form. Two independent reviewers will extract data using the standardised form that will be tested on two articles. A narrative summary will accompany results presented in tables and figures.

住院老年人的久坐行为：范围界定审查方案。

背景技术老年人在住院期间每天花费多达23小时的坐卧时间或躺卧时间。医院环境中的久坐行为（SB）通常与健康状况不佳相关，包括身体和认知能力下降，生活和死亡质量下降以及住院再入院。相反，用轻度至中度的体育活动（例如步行）代替SB可以显着减少30天的医院再次入院风险。鉴于SB对住院老年人的潜在有害影响，至关重要的是，通过广泛探索医院老年人中SB的不同方面来识别当前文献。范围界定审查的总体目标是为住院老年人的久坐行为关键领域提供一份最新证据的文献图。方法将在Pedro，MEDLINE Ovid，Cochrane，Scopus，护理和相关健康文献累积索引，PsychInfo，Embase，Ageline，Joanna Briggs Institute（JBI）和临床试验注册中心中搜索相关出版物。将包括英文出版物以及作者可以提供英文全文的出版物。将包括在医院（包括住院康复设施）或急性和亚急性护理场所以及65岁以上的人群中进行的研究。将采用一种三阶段方法来识别相关文章，包括使用关键字，所有数据库中的关键字和索引词进行数据库搜索以及参考搜索。在筛选标题/摘要之后，将使用标准的选择表对全文进行鉴定，从而选择文章。两名独立的审阅者将使用将在两篇文章上进行测试的标准化表格来提取数据。叙述摘要将随表格和数字一起提供。
