Abstract

Aims: Cognitive frailty refers to the coexistence of physical frailty and cognitive impairment in older adults, without a concurrent diagnosis of Alzheimer's disease or other dementias. This review aims to evaluate the prevalence of CF subtypes and identify influencing factors among Chinese older adults.

Methods: The following databases were searched: PubMed/Medline, Embase, Cochrane Library, WOS, PsycINFO and CNKI et al (1 January 2001 to 20 October 2022). The risk of bias was assessed using the Agency for Healthcare Research and Quality Evidence-based Practice Center Methods Guide. Stata 17.0 software was used to pool the prevalence of cognitive frailty, and the pooled odds ratio and 95% CI of the influencing factors were calculated.

Results: The meta-analysis (56 studies and 80,320 participants) revealed the following prevalence rates: CF (18.9%), reversible CF (19.5%), potentially reversible CF (17.5%), CF in community-dwelling older adults (14.3%), CF in nursing homes (22.7%) and CF in older inpatients (25.2%). Influential factors identified included age, gender, education, nutrition, depression, exercise, sleep and comorbidity.

Conclusions: The prevalence of CF among Chinese older adults is notably high, and it probably underestimates the prevalence of reversible cognitive frailty. It is crucial to encourage adherence to healthy behaviours, as it can effectively reduce and delay the onset of cognitive frailty.

中国老年人认知虚弱的患病率和影响因素：系统回顾与荟萃分析。

目的：认知功能虚弱是指老年人在未同时确诊阿尔茨海默病或其他痴呆症的情况下，同时存在身体虚弱和认知功能障碍。本综述旨在评估中国老年人认知虚弱亚型的患病率，并确定其影响因素：方法：检索了以下数据库：方法：检索了以下数据库：PubMed/Medline、Embase、Cochrane Library、WOS、PsycINFO 和 CNKI et al（2001 年 1 月 1 日至 2022 年 10 月 20 日）。采用美国医疗保健研究与质量机构循证实践中心方法指南对偏倚风险进行了评估。使用Stata 17.0软件汇总认知虚弱的发生率，并计算影响因素的汇总几率比和95% CI：荟萃分析（56 项研究和 80,320 名参与者）显示了以下患病率：CF（18.9%）、可逆性CF（19.5%）、潜在可逆性CF（17.5%）、社区老年人CF（14.3%）、疗养院老年人CF（22.7%）和老年住院病人CF（25.2%）。影响因素包括年龄、性别、教育、营养、抑郁、运动、睡眠和合并症：结论：中国老年人的 CF 患病率明显偏高，而且可能低估了可逆性认知虚弱的患病率。鼓励老年人坚持健康行为至关重要，因为这可以有效减少和延缓认知功能衰弱的发生。
