Loneliness in later life is influenced by both social relationships and real-world constraints, and it can show up even when someone has support nearby. Evidence links loneliness with poorer mental health, including higher depression risk, and with worse physical outcomes such as frailty, mortality, and greater health care use. This page explores who is most affected (including people who live alone, face housing constraints, or have limited digital access) and reviews interventions, from group programs to supportive phone calls.
Key Takeaways
- Approximately 1 in 4 older adults (65+) experience loneliness in the European Union (EU) (European Commission estimate based on survey evidence).
- 6.7% of adults aged 50+ in the United States were classified as 'lonely' in the HRS/HRS-based analysis summarized in a peer-reviewed paper (2016–2018 data; percentage refers to sample classification used in the study).
- Loneliness and social isolation are associated with a 68% increased risk of depression (meta-analysis referenced in WHO evidence).
- Social isolation has been associated with a 2.0x increased risk of mortality (meta-analysis reported in an evidence review).
- Loneliness has been associated with a 1.45x increased risk of mortality (meta-analysis in peer-reviewed literature).
- A peer-reviewed econometric study estimated that loneliness in older adults increases total health care costs by about 25% compared with non-lonely peers (cost modeling in health system setting).
- In England, social isolation and loneliness interventions can reduce costs; a JAMA published cost-effectiveness analysis modeled health care utilization reductions of 7% for targeted outreach (modeling results).
- A systematic review found social isolation and loneliness are associated with increased health care utilization, with a pooled increase in utilization of about 14% (meta-analysis of utilization outcomes).
- Loneliness interventions have been associated with a 30% improvement in social support outcomes in randomized or quasi-experimental studies (meta-analysis of social connectedness interventions).
- In a systematic review, group-based social interventions for older adults reduced loneliness by an average standardized mean difference of about -0.33 (meta-analysis).
- In a large randomized trial of supportive telephone calls for older adults, adherence and contact were achieved in 80%+ of scheduled sessions (trial reported intervention fidelity of high contact).
- In 2021, the European Commission announced €4 million for projects addressing loneliness and social isolation (funding call information).
- In the UK, the 'Marmot' approach includes that social isolation is recognized as a determinant of health; NHS England documents social prescribing as a national program (quantified implementation described).
- In the US, the Older Americans Act programs in 2023 supported community living, including services for socialization; ACL reports supporting over 7.3 million older adults (Administration for Community Living annual report).
