Aging and Health/Medical Problems: Impact of Disability and Chronic Illness on Daily
Living, and the Role of the Healthcare System
-defining health:
-a state of complete physical, mental and social wellbeing and not merely the absence of
disease or infirmity (WHO, 1946)
-free of disability, disease, etc
-a narrow focus of health
-the extend to which an individual or a group is able to realize aspirations and satisfy needs,
and to change or cope with the environment; health is resource for everyday life, not the
objective of living; it is a positive concept, emphasizing social and personal resources as
well as physical capabilities (WHO, 1984)
-need for support
-looks at the spiritual sense
-are you able to meet certain goals? do they see themselves as having a sense of
purpose?
-sense of control; linked to the human rights concept of health
-promotes internal focus of control
-defining illnesses is usually based on the germ theory perspective or biomedical
perspective of disease
-goal is to attack invaders and restore body back to healthy state
-western perspective
-sees illness or disease as an unnatural or abnormal invasion into a healthy body
-treat it with surgery, medication, X rays, etc
-acute illness: a disease with an abrupt or rapid onset and usually a short duration
-treated fairly easily
-ear infection, common cold, flu, etc
-to completely cure the individual is the goal
-chronic illness: a health condition that is long lasting (6 months or longer) and needs to be
managed on a longer term basis (arthritis, diabetes)
-exacerbation of certain symptoms (an acute phase of a chronic illness)
-individuals notice down the line once they notice symptoms getting worse (not noticed
immediately until major deficits become apparent)
-often long term management is the goal, and not necessarily cure (there may not be one,
etc)
-terminal illness: an active and progressive disease with no reasonable chance of cure
(advanced cancer, ALS, etc)
-move from an intent to cure and shift to palliative care (helping to address certain
symptoms that make people’s lives extremely uncomfortable)
-hospice care is palliative care that is specifically delivered to people at the end of life to
make things comfortable for them
-sociological perspective on disease, illness, sickness:
-theories are operated separately
-but can also be interconnected and fold into one another
-disease: based on the medical diagnosis which locates a problem in specific organs or body
systems, and is treated through biomedical treatments
-illness: the subject/personal experience of a disease state or a person who acknowledge s/
he does not feel well

tasks of could only do them with a lot of difficult

reach 65 years of age

-prevalence of most type of disabilities increases with age (mobility, agility, hearing, seeing,
pain, memory and speech)
-most common combination of multiple disabilities in older persons is pain, inflexibility and
immobility disabilities
-older women tend to report higher disability rates then men and have higher rates of chronic
conditions
-whereas for children under the age of 14; boys are diagnosed with more disability
-cardiovascular conditions: coronary artery disease, congestive heart failure, peripheral
vascular disease
-heart attack is one of the leading causes of death and disability in older adults
-mortality rates for persons older than 70 is 2x the rate of younger individuals
-many persons older than 65 experience hypertension
-may lead to edema (swelling) in feet and legs
-risk factors include smoking, obesity, hypertension, etc
-encourage people to engage in exercise, energy conservation techniques (having a chair in
the bathtub, sit on the bed while getting dressed, etc), and maintain an adequate diet
-Stats Canada 2011:
-cardiovascular diseases are defined as diseases and injuries of the cardiovascular system
(heart, blood vessels, veins and arteries, etc throughout the brain)
-considered a form of cardiovascular disease
-since 1952, the cardiovascular death rate in Canada has declined by more then 75% (and
nearly 40% in the last decade) due to advanced research in surgical procedures, drug
therapies, and prevention efforts
-end up saving more people but the individuals deal with more disabilities after surviving
these things
-Canada; every 7 min someone dies from heart disease or stroke
-2008: cardiovascular disease accounted for 29% of all deaths
-neurological conditions (cerebrovascular accident, Parkinson’s disease, sensory losses)
-stoke is one of the leading causes of death and disability in older adults
