Lecture 10
April 4th, 2011.
Epidemiology and demography in health research/Epidemiological research
designs
Epidemiology
The study of the distribution and determinants of health related states in specified
populations and the application of this study to control health problems
Basic science of public health
What are the factors that can cause the disease? Where is occurs?
Health related states- measures of health, not just disease and mortality
Focusing on populations
Then it goes on to apply the study to control health problems; this is why its the
basic science of public health
Demography
Study of human populations, including their size, composition, distribution and
growth as well as the causes and socioeconomic consequences of changes in these
factors
Study of patterns in human populations
Birth rates, death rates, immigration, emigration, etc. Anything related to the
patterns of human populations
Role in Health research
Epidemiology: Subfields/Levels
A)Classified on Level upon which the research focuses on
1. Internal, within the body= Clinical Epidemiology (researches focus on an
individual and want measurements for instance biochemical levels in
individual)
2.Behaviour= Social epidemiology (considers determinants on development on
health and disease) i.e. link between societies and tendency to uptake
smoking individual behaviours
3.Contextual/Structural; outside of the individual = Critical epidemiology
(researches count on to get important policies into place; emphasis is on social
and power relationships) contextual factors that would contribute to the
health status of concerned populations
B)Classified based on type of disease
1.Communicable disease epidemiology (focus on infectious diseases)
2.Chronic-disease epidemiology (certain diseases that are chronic)
C)Classified based on environment where study takes place
1.Community epidemiology
2.Occupational epidemiology (classified based on the workplace; or diseases in a
certain workplace)
D)Classified based on tools
1.Quantitative epidemiology

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.
