Social Isolation Causes Far-reaching Health Effects for Seniors

Social isolation and loneliness are common problems among older adults, and are linked to several health conditions, such as depression and heart disease. According to the Centers for Disease Control and Prevention (CDC), social isolation is a lack of social connection, and loneliness is the feeling of being alone, regardless of the amount of social contact.1

A report from the National Academies of Sciences, Engineering, and Medicine (NASEM) found that more than one-third of adults age 45 and older feel lonely, and almost one-fourth of those age 65 and older are considered to be socially isolated.2

What Effect Does Social Isolation Have on Health?

The NASEM study found that social isolation or loneliness in the elderly was associated with:

  • 50% increased risk of developing dementia
  • 29% increased risk of coronary disease
  • 32% increased risk of stroke
  • 68% increased risk of hospitalization
  • Nearly 4 times increased risk of death

Statistics on Senior Isolation and Loneliness

Studies show that social isolation and loneliness are common problems among older adults. Here are some key statistics about senior isolation:

  • Around 8 million seniors in the United States, or 24 percent of adults age 65 and older, are socially isolated.
  • 44 percent of women age 75 and older live alone.
  • The biggest risk factors for social isolation and loneliness in seniors are contributed to being divorced, widowed, never married, having a disability, living below poverty, limited mobility, and living alone.

Social Isolation and Loneliness are Linked to Illness

Loneliness in seniors has been linked to a number of chronic health conditions. According to The Centers for Disease Control and Prevention (CDC), social isolation & loneliness was associated with a 29 percent increased risk of heart disease and a risk of stroke increased by 32%.

Research has shown that prolonged loneliness is associated with increased risk of premature death, similar to smoking, alcohol consumption, and obesity.

How Lonely Are You?

To assess a loved one’s potential risk of loneliness, consider taking the UCLA Loneliness Scale test. The test is free and only contains 20 questions. According to a study in Sage Journal’s Research on Aging, the following three questions might also be used to gauge a person’s feelings of loneliness quickly.

  1. How often do you feel that you lack companionship?
  2. How often do you feel left out?
  3. How often do you feel isolated from others?

Each question should be answered with “hardly ever,” “some of the time,” or “often.”4
