This report presents key findings on physical, mental, and social aspects of aging using data collected from 50,000 Canadians aged 45-85. It highlights insights related to: physical and psychological health, loneliness and social isolation, caregiving and care receiving, transportation and mobility, work and retirement, physical function, disability and falls, lesbian, gay and bisexual aging, and lifestyle and behaviour, among others. 210 pages.

Chronic kidney disease (CKD) is a decreased level of kidney functioning for a period of three months or more (1). Severity of CKD can vary, but most cases develop slowly without symptoms, are mild or moderate, and do not result in kidney failure (especially if discovered early) (1). People with CKD have an increased risk of developing heart disease or having a stroke (2).

While CKD can develop at any age, it is more common in older adults (2). About half of people aged 75 and older have some degree of CKD, although most of these cases are due to the normal aging process (2).

A routine blood test is commonly done to detect CKD and monitor people with conditions that can affect the kidneys such as diabetes or high blood pressure. Treatment can slow down the progression of CKD and reduce the risk of developing heart disease or having a stroke (2).

There is an age-related decline in kidney function; however, not all individuals will develop chronic kidney disease (CKD) with advancing age.  Those who are genetically predisposed and exposed to lifetime cardiovascular risk factors are likely to develop systemic atherosclerosis and CKD. (1)

Why is it Important?

  • 70.9% of people with CKD have hypertension compared with 20.1% of people without CKD (1)
  • About 1 in 10 people have some degree of CKD and it is more common in women (2)
  • CKD contributes to poor health through its association with inflammation and oxidative stress (1)
  • Malnutrition, weight loss and sarcopenia are common in CKD patients, leading to poor outcomes, such as physical and cognitive dysfunction, manifesting as major geriatric syndromes (1)
  • Frailty is likely to be one of the underlying processes that leads to the clinical manifestations of geriatric syndromes in patients with CKD (1)
  • Functional outcomes, such as cognition and physical functioning, are more relevant outcomes to older patients with CKD (1)
  • Renal function declines physiologically with advancing age and pathologically as a result of associated diabetes mellitus and hypertension (1)
  • Although about half of people aged 75 or more have some degree of CKD, most of these people do not actually have diseases of their kidneys; they have normal ageing of their kidneys  (2)

Key Considerations

  • Interventions should be developed and assessed in terms of maintaining quality rather than quantity of life in order to prevent disability (1)
  • Investigations to exclude treatable kidney disease (e.g. urinary tract infection or obstruction) (2)
  • Reduce progression of kidney disease (by controlling BP to recommended levels with ACEI or ARB therapy) (2)
  • Reduce cardiovascular risk, avoidance of nephrotoxic medications and volume depletion, Lipid-lowering treatment, glycemic control (2)
  • Early detection and management of CKD complications by: avoid renally-excreted medications; adjust medication doses for kidney function and appropriate referral to a nephrologist where indicated (2)
