Loneliness among Older Adults in Contemporary Sociological Literature: Trends, Controversies and Research Agendas
Loneliness among Older Adults in Contemporary Sociological Literature: Trends, Controversies and Research Agendas

Summary/Abstract: Loneliness in later life has emerged as a central concern in contemporary sociology because it concentrates broader transformations in demographic ageing, social inequality, institutional arrangements of care, and changing cultural expectations surrounding relationships, autonomy, and belonging. This article provides a synthetic analysis of the 20 mostcited peer-reviewed articles published between 2023 and 2025 that explicitly focus on loneliness among older adults, with emphasis on sociological and social-gerontological contributions. Rather than treating loneliness primarily as an individual psychological state, the reviewed literature increasingly conceptualizes it as a socially produced and institutionally patterned condition shaped by care environments, migration and minority status, stigma, and normative relational expectations. At the same time, the field has become more reflexive about measurement, demonstrating that prevalence estimates and trend claims are contingent on instruments, modes of data collection, and cultural context. Intervention research has similarly shifted from generic activity-based solutions toward a sociological understanding of interventions as embedded within social infrastructures, organizational routines, and local ecosystems of care. Building on convergences and tensions within this influential corpus, the article identifies key controversies concerning conceptual boundaries between loneliness and social isolation, causal directionality and feedback loops with health, cross-cultural comparability, and the political implications of framing loneliness as an epidemic. From this synthesis, the article articulates a forward-looking research agenda centered on life-course and chronicity-sensitive models, culturally grounded yet comparative measurement strategies, meso level institutional analysis of care and community settings, intersectional approaches to inequality, and theory-driven evaluation of interventions. Taken together, the analysis positions loneliness in later life not as an individual deficit but as a social outcome reflecting how contemporary societies organize belonging, recognition, and access to meaningful participation in older age.
