AGEING Flashcards
(94 cards)
Define Aging and what are the 3 indicators
- happens before physical signs become obvious
- indicators of ageing:
1. chronological age
2. functional capacity
3. life stage - used to classify people into groups
Define chronological age
- age since birth
- used to determine eligibility for programs (ex. Canada Pension)
- remains the dominant legal definition of when a person becomes “older”
- everyone’s experience is different so you can’t lump them all together (doesn’t capture the heterogeneity of adults)
Define functional age
- observable individual attributes to assign to people to age categories:
1. Physical appearance
2. mobility
3. Strength
4. mental capacity - does not always match chronological age
Define life stages & what are the 3 stages
broad categories loosely based on what ideas of ageing
- middle age, later adulthood and old age
Middle age
when most people first become aware that physical ageing has noticeably changed them
Later adulthood
when declines in physical functioning and energy availability begin
Old age & what age is rates of decline higher?
begins around late 70s to early 80s
- characterized by physical frailty, slower mental processes, activity restrictions
- 85 is when rates of decline are higher
define Life span
the theoretical limit on the length of life (115-120years max)
define Life Expectancy
average number of years members of an age category is expected to live given base-year mortality rates
Life Expectancy, at birth and at age 65, by sex and province - trends and facts
- Canadian life expectancy is 82 years (both sexes)
- at age 65 both sexes are expected to live 20.8 more years
- Ontario and BC have the highest life expectancy (then Quebec, Alberta, PEI and Saskatchewan)
- Nunavut has the lowest life expectancy
Global and Canadian % of younger and older adults
the number of children is declining in both Canada and the global population
(less young and elder)
Number of years for a population age 65+ to increase from 7% to 14% - what are the facts
- 14% of pop. that is an elder is considered to be an OLD population
- France has had 115 years to go from 7%-14% (1865-1980)
- Singapore has had 19 years to fo from 7%-14% (2000-2019)
projected increase in global population between 2005-2030 - what is the fastest growing groups of older adults?
85 and 100+
the increasing burden of chronic noncommunicable diseases: 2002-2030 - what happens to low, middle and high-income countries?
Low/Middle: drop in communicable diseases, increase in non-communicable disease
High - Income countries: increase in non-communicable diseases
This causes a rise in cost in health care
other key global trends in population ageing (3)
- changing the family structure: fewer kids and family supports
- changes in work and retirement: pensions
- social insurance programs
population pyramids (2011 vs 2016)
- The classic pyramid is no longer the shape of a pyramid bc of the age of the population is changing
- In 2011 we were considered an older country
- Now in 2016, we were almost 17% of people are older
Causes of pop. ageing - FERTILITY
- low birth rates and more people are choosing to delay childbirth
- the main force behind pop ageing
- baby boom followed by low fertility rates
why fertility decline in the West??
- Urbanization, declining value and increase the cost of children
- Women are getting more educated and going into the workforce more
- Effective means to control reproduction
Causes of pop. ageing - MORTALITY
- low death rates mean more people are surviving into old age
- women spend more of their remaining life in worse health than men
Mortality: compression of morbidity hypothesis
more people are able to postpone the age of onset chronic disability
- pushing illness longer so compressing the number of years that we aren’t feeling well (healthier longer)
Mortality: gender
older women will spend proportionately more of their remaining years of life (32.4%) in poor health than men (21.1%)
Causes of pop. ageing - MIGRATION
- a small role in pop. ageing
- people moving around
Survival curves: Rectangularization
- more people are surviving
- due to advancements in medicine, improvement in sanitation
Longevity quiz - what is it? and how to calculate?
- quiz that has a series of questions with associated points to determine how long you will live
- add scores together then divide by 5 then add 84
