Abstract

Background: A systematic review/meta-analysis synthesising the existing evidence regarding the prevalence of loneliness and social isolation among individuals with mild cognitive impairment (MCI) or dementia is lacking.

Aims: A systematic review and meta-analysis was conducted to investigate the prevalence and factors associated with loneliness and social isolation among individuals with MCI or dementia.

Method: A search was conducted in five established electronic databases. Observational studies reporting prevalence and, where available, factors associated with loneliness/isolation among individuals with MCI and individuals with dementia, were included. Important characteristics of the studies were extracted.

Results: Out of 7427 records, ten studies were included. The estimated prevalence of loneliness was 38.6% (95% CI 3.7-73.5%, I2 = 99.6, P < 0.001) among individuals with MCI. Moreover, the estimated prevalence of loneliness was 42.7% (95% CI 33.8-51.5%, I² = 90.4, P < 0.001) among individuals with dementia. The estimated prevalence of social isolation was 64.3% (95% CI 39.1-89.6%, I² = 99.6, P < 0.001) among individuals with cognitive impairment. Study quality was reasonably high. It has been found that living alone and more depressive symptoms are associated with a higher risk of loneliness among individuals with dementia.

Conclusions: Social isolation, and in particular loneliness, are significant challenges for individuals with MCI and dementia. This knowledge can contribute to supporting successful ageing among such individuals. Future research in regions beyond Asia and Europe are clearly required. In addition, challenges such as chronic loneliness and chronic social isolation should be examined among individuals with MCI or dementia.

轻度认知障碍或痴呆患者中孤独感和社会隔离的患病率:系统回顾和荟萃分析
背景:缺乏一项综合现有证据的系统综述/荟萃分析,以综合轻度认知障碍(MCI)或痴呆患者中孤独感和社会隔离的患病率。目的:通过系统回顾和荟萃分析,调查轻度认知障碍或痴呆患者中孤独感和社会隔离的患病率及其相关因素。方法:对已建立的5个电子数据库进行检索。观察性研究报告了轻度认知障碍患者和痴呆患者的患病率以及与孤独/孤立相关的因素(如果有的话)。提取了研究的重要特征。结果:在7427份记录中,纳入了10项研究。MCI患者的孤独感患病率为38.6% (95% CI 3.7-73.5%, I2 = 99.6, P < 0.001)。此外,痴呆患者中孤独感的估计患病率为42.7% (95% CI 33.8-51.5%, I²= 90.4,P < 0.001)。在认知障碍个体中,社会隔离的估计患病率为64.3% (95% CI 39.1-89.6%, I²= 99.6,P < 0.001)。研究质量相当高。研究发现,独居和更多的抑郁症状与痴呆症患者孤独感更高的风险有关。结论:社会孤立,尤其是孤独感,是MCI和痴呆患者面临的重大挑战。这方面的知识有助于支持这些人成功地步入老年。未来显然需要在亚洲和欧洲以外的地区进行研究。此外,应在轻度认知障碍患者或痴呆症患者中检查慢性孤独和慢性社会孤立等挑战。
