• Healthy aging is now an achievable goal for many.
• Aging and disease are separate entities.
• Aging is an individual process that affects each
... [Show More] person differently.
• The chronologic age of 65 is the standard in the United States for
being considered an older adult (elderly).
• By 2050, one in five Americans will be over the age of 65.
• The concept of aging is further defined as young-old (65 to 74),
middle-old (75 to 84), old-old (over 85), elite-old (over 90), centenarian
(over 100), and super-centenarian (110 and over).
• Eighty percent of people over the age of 70 have at least one chronic
condition, and 50% have multiple health problems.
Theories of Aging
1. Psychosocial Theories:
a. Disengagement Theory: Progressive social disengagement occurs
naturally with aging and is accepted by the older adult. Variation in
disengagement across older populations is related to cultural style and
behaviors in different geographic regions.
b. Activity Theory: Successful again requires a high level of activity and
involvement to maintain life satisfaction and positive self – esteem.
2. Biologic Theories:
a. Pacemaker Theory: A programmed decline or cessation of many
concepts occurs in the nervous and endocrine systems.
b. Immunity Theory: A programmed accumulation of damage and
decline of the immune systems’ function (immunosenescence) takes place
due to oxidative stress.
c. Wear-and-Tear Theory: After repeated use, damaged cells in the
body structures wear out from the harmful effects of internal and external
stressors, now known as free radicals.
3. Developmental Theories:
a. Erik Erikson’s Theory: Theory identifies 8 stages of developmental
tasks throughout the life span; 8th stage is integrity versus despair
b. Maslow’s Theory: Maslow’s hierarchy of needs ranks an individual’s
needs from the most basic to the most complex. Maslow uses the terms
physiologic, safety and security, belonging, self-esteem, and self-actualization
needs to describe the process that generally motivates
individuals to move through life.
HINT: The concept of aging is shifting from viewing older adults as frail
and dependent to being able to engage in healthy living. The majority of
those aged 65 and older regard their health as good or excellent. The ability
to perform activities of daily living (ADLs) is a more accurate measure of
an older person’s age than chronologic age.
Physiologic Changes
• Aging effects every cell in every organ of the body, but not at the
same rate
• Three physiologic changes are clinically significant in making older
adults vulnerable to injury & disease:
o Loss in compensatory reserve (making up for a loss in physiological
compensation; vital signs)
o Progressive loss in efficiency of the body to repair damaged tissue
o Decreased functioning of the immune system processes
• Diseases in older adults do not always present with classic signs and
symptoms
• Physiologic changes increase more rapidly with increasing age
• Aging changes are influenced by genetic makeup & environment
HINT: Questions may ask about teaching and designing rehabilitation
programs for older adults. The answers should contain information about
exercise and nutrition. [Show Less]
