社会的孤立
Social isolation and loneliness in older adults is associated with an increased risk for poor mental and physical health and increased mortality. There is an increased risk for early mortality in individuals experiencing social isolation compared to those who are not socially isolated. Studies have found social isolation is associated with increased risk in physical health conditions including high blood pressure, high cholesterol, elevated stress hormones, and weakened immune systems. Research also suggests that social isolation and mortality in the elderly share a common link to chronic inflammation with some differences between men and women. Social isolation has also been found to be associated with poor mental health including increased risk for depression, cognitive decline, anxiety, and substance use. Social isolation in elderly individuals is also associated with an increased risk for dementia.
