Experiencing social isolation

For older adults, social isolation can result from a significant event, such as the loss of a loved one or retirement, or a combination of several smaller events. In general, the more risk factors a person has, the greater likelihood that they’ll experience social isolation. However, the presence of risk factors doesn’t necessarily mean a person will experience social isolation. Whether a person experiences it or not, or to what degree it’s experienced, depends on their coping skills and the support available from family, friends, and the community.

Risk factors

The risk factors for social isolation are many and varied. They include:

  • living alone
  • being age 80 or older
  • having multiple chronic health conditions that may impact your mobility, such as diabetes, dementia or osteoarthritis
  • size of your 'social network'
  • frequency of contact with the members of your social network
  • living with low income
  • challenges in using technology
  • where you live
  • lack of access to transportation
  • changes in family structures, such as younger people moving for work and leaving older adults behind
  • critical life changes such as retirement, death of a spouse or losing a driver's license, and
  • age-related disorders such as hearing loss, loss of speech, fear of falling and incontinence.

Groups at increased risk

There are also specific groups of older adults who are at greater risk of social isolation, including:

  • caregivers
  • Indigenous peoples
  • newcomers to Canada, and
  • lesbian, gay, bisexual and transgender people.

What can you do?

Fortunately, there are many proactive steps that you can take to reduce the risk of social isolation, including:

  • managing chronic conditions and promoting brain health to optimize your function and mobility
  • regularly engaging in both physical and social activities
  • using technology to expand your social network and to increase the frequency of contact (especially between different generations)
  • being open to alternate transportation options
  • volunteering, and
  • addressing age-related health conditions.
