Objectives: This systematic review and meta‐analysis aimed to determine the prevalence of loneliness and social isolation among informal carers of individuals with dementia and to identify potential influencing factors. Methods: We conducted a comprehensive search across 10 electronic databases, including PubMed, Cochrane, Embase, Web of Science, PsycINFO, CINAHL, Scopus, Chinese Biomedical, China National Knowledge Internet, and WANFANG. Our search strategy covered the inception of the databases up to September 16, 2023, with an updated search conducted on March 8, 2024. Prevalence estimates of loneliness and social isolation, presented with 95% confidence intervals, were synthesized through meta‐analysis. Subgroup analyses and meta‐regression were employed to explore potential moderating variables and heterogeneity. Results: The study encompassed 27 research papers involving 11,134 informal carers from 17 different countries. The pooled prevalence of loneliness among informal carers of individuals with dementia was 50.8% (95% CI: 41.8%–59.8%), while the pooled prevalence of social isolation was 37.1% (95% CI: 26.7%–47.6%). Subgroup analyses and meta‐regression indicated that various factors significantly influenced the prevalence of loneliness and social isolation. These factors included the caregiving setting, study design, the intensity of loneliness, geographical location (continent), data collection time, and the choice of assessment tools. Conclusions: This study underscores the substantial prevalence of loneliness and social isolation among informal carers of individuals with dementia. It suggests that policymakers and healthcare providers should prioritize the development of targeted interventions and support systems to alleviate loneliness and social isolation within this vulnerable population. Key points: Informal carers of people with dementia contend with unique circumstances that render them susceptible to both loneliness and social isolation.There is a significant prevalence of loneliness and social isolation in informal carers of individuals with dementia.Several significant moderators influence the prevalence of loneliness and social isolation among informal carers of individuals with dementia.Moderator analysis can guide targeted interventions and support systems for at‐risk informal carers of people with dementia to alleviate loneliness and social isolation.

Loneliness is a serious problem for older people, which can be alleviated by social support. The dramatic population ageing together with social and economic change in China increases the likelihood of loneliness and the availability of different sources of social support of older people. The aim of this review was to identify the prevalence of loneliness and its related factors and sources of social support of older people in China. Electronic literature searches were conducted in September 2011 using Web of Science, PsycINFO, MEDLINE, PubMed, CINAHL, China Academic Journal and VIP Database for Chinese Technical Periodicals. Twenty-six papers were identified and reviewed. The prevalence of loneliness varied across the studies, reflecting the different measurements and samples. Marital status, gender, age, educational level, economic level, living arrangements, health status and social support were significant factors related to loneliness. The family was the most important source of social support followed by friends. The receipt of family support improved subjective well-being and mental health, but the effects of support from friends were inconsistent. Chinese older people received relatively little support from neighbours, governmental or other social organisations. Further well-designed studies are needed to identify additional factors related to loneliness and to understand the support from friends, neighbours, formal organisations and other sources.

Aims and objective: To synthesise current international empirical evidence on loneliness and social isolation in Chinese late‐life immigrants. Background: Loneliness causes adverse health consequences in Chinese late‐life immigrants leading to increased utilisation of often increasingly limited healthcare resources. However, little is known about how Chinese late‐life immigrants perceive and experience loneliness and social isolation in their host countries. Design: An integrative review methodology. Methods: Using a systematic search strategy, Google scholar and databases, such as Scopus, Web of Science, PubMed, CHNAHL, Medline and open access Theses were searched. No limitation was placed on publication date. Peer‐reviewed studies published from the database inception to May 6, 2021 in the English language were included. The review process is reported according to PRISMA. Results: Eight articles met the criteria and were included in this review. Two themes resulting from the data synthesis process were identified. Firstly, 'disrupted social relations after late‐life immigration' and secondly 'moving away from filial expectations'. Conclusion: Loneliness and social isolation are commonly experienced by Chinese late‐life immigrants when residing in host countries. Understanding and identification of the sources of loneliness and social isolation among late‐life immigrants are essential prompts for healthcare professionals, particularly nurses, to engage sensitively with Chinese late‐life immigrants. Nurses culturally relevant care delivery in a variety of settings may best serve recipients' social and health related needs. Relevance to clinical practice: This integrated review informs the planning of health and social services for addressing Chinese late‐life immigrants' experiences of loneliness and social isolation. Focused attention on cultural responsiveness is an important component of providing quality and safe nursing care. This review of the recent evidence on socially‐rooted health concerns affected by both immigration and ageing will help advance nursing practice in providing culturally responsive care interventions.
