From the Guidelines
Social isolation is primarily caused by a combination of individual, social, and environmental factors, including mental health conditions, physical disabilities, and technological barriers, as well as social and cultural factors, with the most recent evidence suggesting that hearing loss is a significant contributor to social isolation 1.
Individual Factors
- Mental health conditions like depression and anxiety
- Physical disabilities that limit mobility
- Personality traits such as introversion or social anxiety
- Hearing loss, which can lead to social isolation and decreased social participation 1
Social Factors
- Major life transitions like retirement, relocation, or bereavement
- Relationship breakdowns and caregiving responsibilities that restrict social engagement
- Social stigma related to physical or cognitive deficits
Environmental Contributors
- Geographic isolation in rural areas
- Lack of transportation options
- Poverty that limits social participation
- Technological barriers that prevent digital connection
Cultural Factors
- Language barriers
- Discrimination
- Cultural differences
Recent Evidence
- A 2024 study found that hearing loss is a significant risk factor for social isolation, with older adults with hearing loss being more likely to experience social isolation and decreased social participation 1
- Another study found that the use of robotic devices can potentially reduce social isolation in older adults, but can also exacerbate it if not used appropriately 1
- A 2004 study highlighted the importance of addressing social isolation in stroke patients, who are at risk of social withdrawal and isolation due to physical and cognitive limitations 1
Key Takeaways
- Social isolation is a complex issue that requires a multifaceted approach to address
- Individual, social, and environmental factors all contribute to social isolation
- Recent evidence highlights the importance of addressing hearing loss and social isolation in older adults
- Technological interventions can be effective in reducing social isolation, but must be used appropriately to avoid exacerbating the issue.
From the Research
Contributors to Social Isolation
The contributors to social isolation can be understood through various factors and their interrelations. Key points include:
- Having a smaller social network, more functional limitations, and limitations in engaging in meaningful activities is associated with higher levels of loneliness and greater social isolation 2.
- Social isolation is associated with depression and lower self-ratings of health, with the association between social isolation and health mediated by loneliness 2.
- Poor interaction with friends and no social participation show robust associations with a wide range of health and well-being outcomes 3.
- Social isolation affects health through biological, behavioral, and psychological pathways and is associated with physical and psychological/emotional well-being, increases morbidity and mortality rates, and lowers quality of life 4.
- Social disconnectedness predicts higher subsequent perceived isolation, which in turn predicts higher depression symptoms and anxiety symptoms, suggesting bi-directional influences 5.
Factors Influencing Social Isolation
Several factors influence social isolation, including:
- Age, with individuals in older cohorts (80+) reporting less social support 2.
- Gender, with some evidence regarding effect modification by gender in the associations between the components of social isolation and health and well-being 3.
- Functional limitations and limitations in engaging in meaningful activities, which are associated with higher levels of loneliness and greater social isolation 2.
- Social support, with nondirective emotional support and directive instrumental support being important in reducing anxiety and depression among people who are socially isolated 6.
Health and Well-being Outcomes
Social isolation is associated with a range of negative health and well-being outcomes, including:
- Increased risk of mortality 3, 4.
- Higher levels of depression and anxiety symptoms 2, 6, 5.
- Lower self-ratings of health 2.
- Cognitive decline and disruptions in sleep 4.
- Poor oral health 4.
- Decreased physical performance/function and a decline in physical activity 4.
- Decreased overall physical health, poor health behaviors, and self-care, and decreased health-related quality of life 4.
