This umbrella review and research update explores experiences of loneliness and social isolation in older immigrants to understand their support needs and the effectiveness of current interventions. Nine quantitative and qualitative studies discussing loneliness and/or social isolation in older immigrants were identified. Six key themes emerged: language and cultural barriers, life-course intersections, family relationships and obligations, meaningful opportunities as a counter-strategy, regaining self-esteem, and effectiveness of peer/community support. Assessment of needs was a central topic in the literature. Peer and community support is an effective intervention targeting loneliness and social isolation in older immigrants as it connects participants and creates meaningful relationships.
Keywords: Loneliness; current interventions; older immigrants; peer and community support; social isolation.
