S1L1 - Population Science Flashcards
What is demography?

What is epidemiology?
Study of the diseases in populations
Study of the distribution and determinants of health related states or events and the application of this study to the control of diseases and other health problems.
What are statistics?
Study of data in numerical form

What is a study?
The collection, analysis and interpretation of data in an unbiased and systematic approach.
What factors affect population health?
Demographic shape
Economic composition
Behavioural and lifestyle factors
What does the burden of disease, ageing and disability rely on?
Population size
Population shape
Age-sex specific rates
What are global determinants of health?
Global warming
Socio-demographic factors
Population factors.
What are the implications for health due to global warming?
Extreme heat Sea level rising displacing people. Air pollution and increasing allergens Severe weather Environmental degradation Degraded living conditions & social inequities Changes in vector ecology. Water and food supply impacts Water quality impacts.
What are the characteristics of an expansive population pyramid?
Developing country, high birth rates, high mortality of infants, low life expectancy
What are the characteristics of a constrictive population pyramid?
Graphs are tapered at the bottom. Long life expectancy, low birth rate, typical of countries of higher levels of social and economic development. Will struggle to support older generation.
What do stationary population pyramids tell us about the population?
Populations not growing, rectangular shape, developed nations, high life expectancy, low birth rates/
What are the consequences of an ageing population?
Higher number bed days in older people and therefore greater stress on health system.
A greater number of people living with one or more chronic conditions. These patients will cost more. The longer people live, the more the NHS spends.
