CDC: Loneliness, Social Isolation in Older Adults Linked to Serious Health Issues
Loneliness and social isolation in older adults are serious public health risks affecting a significant number of people in the United States and putting them at risk for dementia and other serious medical conditions.
A new report external icon from the National Academies of Sciences, Engineering, and Medicine (NASEM) points out that more than one-third of adults aged 45 and older feel lonely, and nearly one-fourth of adults aged 65 and older are considered to be socially isolated.
Older adults are at increased risk for loneliness and social isolation because they are more likely to face factors such as living alone, the loss of family or friends, chronic illness, and hearing loss.
Loneliness is the feeling of being alone, regardless of the amount of social contact. Social isolation is a lack of social connections.
Social isolation can lead to loneliness in some people, while others can feel lonely without being socially isolated.
Health Risks of Loneliness Although it’s hard to measure social isolation and loneliness precisely, there is strong evidence that many adults aged 50 and older are socially isolated or lonely in ways that put their health at risk. Recent studies found that:
Social isolation significantly increased a person’s risk of premature death from all causes, a risk that may rival those of smoking, obesity, and physical inactivity.
Social isolation was associated with about a 50% percent increased risk of dementia.
Poor social relationships (characterized by social isolation or loneliness) was associated with a 29% increased risk of heart disease and a 32% increased risk of stroke.
Loneliness was associated with higher rates of depression, anxiety, and suicide.
Loneliness among heart failure patients was associated with a nearly 4 times increased risk of death, 68% increased risk of hospitalization, and 57% increased risk of emergency department visits.
