Sedentary time (ST) is an important risk factor for a variety of health outcomes in older adults. Consensus is needed on future research directions so that collaborative and timely efforts can be made globally to address this modifiable risk factor. In this review, we examined current literature to identify gaps and inform future research priorities on ST and healthy ageing. We reviewed three primary topics:(1) the validity/reliability of self-report measurement tools, (2) the consequences of prolonged ST on geriatric-relevant health outcomes (physical function, cognitive function, mental health, incontinence and quality of life) and(3) the effectiveness of interventions to reduce ST in older adults.
A trained librarian created a search strategy that was peer reviewed for completeness.
Self-report assessment of the context and type of ST is important but the tools tend to underestimate total ST. There appears to be an association between ST and geriatric-relevant health outcomes, although there is insufficient longitudinal evidence to determine a dose-response relationship or a threshold for clinically relevant risk. The type of ST may also affect health; some cognitively engaging sedentary behaviours appear to benefit health, while time spent in more passive activities may be detrimental. Short-term feasibility studies of individual-level ST interventions have been conducted; however, few studies have appropriately assessed the impact of these interventions on geriatric-relevant health outcomes, nor have they addressed organisation or environment level changes. Research is specifically needed to inform evidence-based interventions that help maintain functional autonomy among older adults.This consensus statement has been endorsed by the following societies: Academy of Geriatric Physical Therapy, Exercise & Sports Science Australia, Canadian Centre for Activity and Aging, Society of Behavioral Medicine, and the National Centre for Sport and Exercise Medicine.
久坐时间（ST）是老年人多种健康结果的一个重要危险因素。需要就未来的研究方向达成共识，以便在全球范围内共同努力及时应对这一可改变的危险因素。在这篇综述中，我们检查了当前的文献，以确定 ST 和健康老龄化研究的差距和未来研究重点。我们审查了三个主要主题：（1）自我报告测量工具的有效性/可靠性，（2）长时间久坐对老年相关健康结果（身体功能、认知功能、心理健康、尿失禁和生活质量）的影响，以及（3）减少老年人久坐时间的干预措施的有效性。

对 ST 的背景和类型进行自我报告评估很重要，但这些工具往往低估了总 ST。ST 似乎与老年相关的健康结果有关，尽管没有足够的纵向证据来确定剂量反应关系或临床相关风险的阈值。ST 的类型也可能影响健康；一些认知上参与的久坐行为似乎对健康有益，而花在更被动活动上的时间可能有害。已经对个体层面 ST 干预的短期可行性研究进行了研究；然而，很少有研究适当评估这些干预对老年相关健康结果的影响，也没有解决组织或环境层面的变化。需要专门研究为基于证据的干预措施提供信息，以帮助维持老年人的功能自主性。该共识声明得到了以下协会的认可：老年物理治疗学院、澳大利亚运动与运动科学学院、加拿大活动与老龄化中心、行为医学学会和国家运动与运动医学中心。
