W6 health and mortality Flashcards
what is life expectancy?
the mean length that one cohort is expected to live assuming the mortality rates of a given year
what is Healthy Life Expectancy?
the combined measure of health and mortality
–> average number of years that a person can expect to live in good health
what does Fries (1983) say?
compression of morbidity
the life expectancy is gonna hit the biological limit and the average onset of morbidity will be postponed (the time for being ill is compressed)
what does Gruenberg (1977) say?
expansion of morbidity
even the life expectancy is getting longer, because the epidemiology is staying the same, years with ill is going to be increasing at the end of life
what does Manton (1985) say?
Dynamic equilibrium
it’s the continuous status quo;
the increase in life expectancy is accompanied with postponent of the onset of morbidity
obesity rate?
gradually increasing from 15% to 25% (1995-2009)
the number of smokers in UK?
decreasing from 46% to below 20% (1974-2013)
what does Omran (1971) say?
epidemic transition:
the disease replacement from infectious ones to chronic ones dues to expanded public health and sanitation
what are the three stages of epidemic transition?
1: The Age of Pestilence and Famine: Mortality is high and fluctuating precluding sustained population growth
- 12000 years before the agricultural revolution
2: Age of Receding Pandemics: Modernisation triggers a decrease in mortality, which accelerates as epidemic become less frequent or disappear. Life expectancy is increasing – sustained population growth
3: Age of Degenerative and Man-Made(Non communicable) Diseases: Mortality continues to decline and eventually approaches stability at a relatively low level. Life expectancy continuous to increase reaching unprecedented levels
- -> started in the first half of 1900s
what is Mc Keown’s thesis?
the increase in life expectancy is happening due to economic growth, rising living standards, public health measures and improved nutrition
what is the germ theory of disease?
theory arguing that diseases are caused by the presence and action by specific micro-organisms
–> critical in terms of changing both individual behaviours and health infrastructure
according to Rosling (2010), what is the historical trend of increase in life expectancy?
in 1948: the gap between countries was biggest
(western countries were top, Japan in catching up, colonized countries are still low)
civil war, WW2–> really decreases life expectancy
what does preston curve (1975) say?
the relationship between income and life expectancy?
what are the three ppl saying that social factors are equally as important as medical system?
Bunker et al (1995), Mcginiss et al (2002)
what is health inequality?
differences in health status or in distribution of the health determints ex) access to proper information, income that allows access to healthy products
