Epidemiology
-Public Health- informs policy and health practices
-Describe the extent of disease in a population and the natural history
-Disease Preven
-Resource allocation
Uses of epidemiology
- Describe both healthy and unhealthy populations
- Establish risk factors
-Determine the health of a community

Study of
study of the distribution and determinants of health-related states or events in human populations and the
application of this study to the prevention and control
of health problems.
Epidemiology
is conducted using an appropriate study design to
test the hypothesis.
research study
is designed to describe the health
status of a population to explain the etiology, and to serve as a basis
to develop prevention and control program
science of epidemiology
Rigorous set of rules to conduct epidemiologic research
SCIENTIFIC METHOD
statement based on sound biological theory that can be tested
HYPOTHESIS
it is stated as if there will be NO relationship
between the study factors and the outcome
Null HYPOTHESIS
characterization of the distribution of
health-related states or events
Descriptive Epidemiology
Investigates causes and associations,
testing hypotheses, and identifying causes of health- related states
or events.
Analytical Epidemiology
Types of Epidemiology
Descriptive and Analytical
Steps to conduct and epidemiologics Research
Determine the Primary Agent
Understand the causation
Determine the characteristic of agent
Determine the mode of transmission
Determine the Cotributing factors
Asses Geographic Factors
Define Natural History
Determine Control measure
Determine prevention measure
Public health Serrvices
Determine Hypothesis
Investigate the population demographically
Describe both healthy and unhealthy populations
Nonmodifiable - age or sex
Modifiable - behavior or lifestyle
Establish risk factors
By counting the number of people with specific diseases or
poor health habits in an area
ex. poor health community due to poverty
Determine the health of a community
guides healthcare resources and
interventions
Resource Allocation
identifies risk factors and preventive
measures
Disease prevention
Describe disease occurrence
Identifies the cause of disease
Describe the extent of disease in a population and the natural
history
De
plays an important role in meeting public health objectives
aimed at promoting physical, mental, and social well-being in
the populatio
