midterm 1 Flashcards
what is gerontology?
the scientific study of old age and the process of growing old
why has the aging population increased?
longer life expectancy; lower fertility rates; immigration
what are three important population trends of recent years? how would a 2031 population pyramid show this?
the dramatic growth in the size of the older age cohorts (aged 40+)
a continued higher proportion of women compared with men in the oldest cohorts
the movement of the baby boom cohorts into old age
the 2031 pyramid is top-heavy, with small younger groups below a large older population.
which “states” of Canada are expected to experience the most growth by 2031?
Nunavut and Northwest Territories
what is intergenerational equity?
balanced support of older and younger people through public policy and public expenditures
by 2030, almost ____ of Canada’s population will be over the age of 65?
25%
as the population ages, what are the changes in social structure?
Family structure
- Three and more generations may live simultaneously and/or in the same household
Education and job market
- Healthier older adults active in the society
Health and social policies
as the population ages, what are the changes in population health?

More cost?
- ‘Aging’ is responsible for only 1% of yearly increase in health care costs
describe mental health in adults
Levels of ‘happiness’ and ‘life satisfaction’ are higher in older adults compared to 25-64y group
describe mental health in older adults
Almost 70% of older adults perceive their mental health ‘excellent’ or ‘good’
- Relates to economic and environmental efficiency (not economic growth)
differentiate between stereotyping, prejudice, and discrimination
stereotype: Beliefs not well supported by evidence
prejudice: We decide based on our beliefs
discrimination: We act based on our beliefs
what does stereotyping, prejudice, and discrimination result in?
ageism!!
ageism is caused by…?
The young and the middle-aged feel distaste for aging
They see old age as a time of weakness, sickness, and dying
People know little about old age and what they do know is based on myth and fear
what is the best way to fight ageism?
Demystifying the myths
By education
as people grow old, is deterioration in physical health inevitable?
yes due to wear and tear. but a healthy diet can modify the “aging” process
what two aspects of aging form the focus of gerontology?
how aging affects the individual, and how an aging population affects society

NOPE!!
Frequency of participation in social activities appears equal for all adult age groups
Community centers for older people are quite popular
define life expectancy
the average number of years a person is projected to live; given no dramatic change in causes for death happens
what has caused an increase in life expectancy?
Better medical treatment

Better public health, effective health promotion
- Seat belts, smoking cessation
Epidemiological transition
- A more influential reason
define epidemiological transition
The replacement of infectious diseases by chronic degenerative diseases over time due to
- expanded public health and sanitation

Happens when in the process of economic development, the vast majority of the population gains reliable access to the basic material necessities of life
Demographic results
- People live longer
what are the two major trends that still affect the aging structure?
Baby boom (1946-1964)

differentiate between fertility rates and birth rates
fertility is how many babies a woman is expected to have in her lifetime (not measuring pregnancy but births)
birth rate is how many births per 1000 woman
describe the 4 stages of demographic transition
Stage I: High fertility and high mortality. Small population. Slow and varied population growth. High proportion of young people, small proportion of older people.
Stage II: High fertility; mortality begins to decline. Population begins to grow as more children survive. Population explosion may occur, and society may get younger. Small proportion of elderly people.
Stage III: Fertility declines and mortality declines further. Population growth begins to level off at larger size. This is stage of the transition from a young high-growth to an older low-growth population.
Stage IV: Low fertility, low mortality. Low population growth and large proportion of older people in the population.
what’re demographic transitions?
from high birth & high death rate to low birth & low death rate
how do you calculate dependency ratio?
((age 0-19)+(age 65+))/(age 20-64)
how do you calculate old age dependency ratio?
the number of people age 65 and over divided by the population age 20 to 64
how do you calculate young age dependency ratio?
the number of people age 0 to 19 divided by the population age 20 to 64
what are the extreme views on increase in older age dependency ratio?
Demographic determinism

what are the three stages of later life when people may choose to move?
retirement stage
- when freedom from the need to live near work allows people to move to a more pleasant climate and to have a more relaxed lifestyle
disability stage

what is crude dependency rate?
are based solely on the number of people in each age group
does not address the economic burden of an older population
demographic determinism assumes…?
that population dynamics determine the future of social relations and social institutions
has the overall dependency ratio decreased in the last decades of the 20th century? why?
yes. also consider the younger population which has decreased
What are the cons of using the crude dependency ratio?
It does not address the economic burden of an older population. For example, seniors rely on income security and healthcare programs that cost more for seniors than for the non-elderly population
It only tells “part of the story” because it is based solely on the number of people in each group
It does not account for the face that children are mainly covered through transfers from their parents
Why do some economists urge caution in using dependency ratios to predict future costs?
because they are only considered to be rough indicators of the extent to which one group in a population is dependent on another

increase in the rate of chronic illnesses
also known as EPIDEMIOLOGICAL TRANSITION
how common are chronic conditions in those of older age?
84.4 percent of senior women and 82.2 percent of senior men have at least one chronic health problem.
pretty common!
what are three reasons for the increased death rate among seniors?
immune cells in the body decrease with age, chronic low-grade inflammation increases with age, and some medications (such as corticosteroids) may inhibit the immune system. In addition, lifestyle conditions such as obesity undermine immune function.
what is health deficit accumulation?
The accumulation of medical condition; disabilities and chronic illnesses over time as a person ages
How do technology aids and devices positively impact older people?

Improved well-being and quality of life
Improved independence
what are the 3 things for aids to be useful?

what are the 3 signs of successful aging according to the rowe and kahn model?
(1) low chance of disease and disability;
(2) high mental and physical functioning;
(3) active engagement in social relations and productive activity
explain the SOC model of successful aging
selectactivities that optimize their ability. When they can no longer engage in an activity, they compensate for losses by setting new priorities
why does the canadian government provide support foe healthy aging?
the people of Canada want to have programs that improve the lives of older people
health promotion can delay and in some cases decrease the use of expensive healthcare services.
describe the information-processing model used by most researchers
sensory -> short-term -> long-term
what is working memory?
recently acquired info is manipulated and processed at the same time as its being stored temporarily
what is a cognitive reserve?
exceptional mental performance, especially when one has to work at max mental capacity
what are the four findings from research the describe mental growth and development in later life?
