PH approach steps
Surveillance (What is the problem?)
Risk factor identification (What is the cause?)
Intervention eval (What works?)
Implementation (How do you do it?)
What does epidemiology enable us to do?
Enables us to determine where dzs originate, how or why they move through pops, and how we can prevent them
What is PH surveillance used for?
To monitor a PH situation
What is the purpose of PH laboratories?
Support PH by performing tests to confirm dz diagnoses, conducting research, and training.
What is the purpose of PH informatics?
Deals with the methods for collecting, compiling, and presenting health info (particularly electronic data)
What does prevention effectiveness do?
Provides important economic info for decision and policy makers to help them choose the best prevention option available
What are the core sciences of public health?
Prevention effectiveness
Surveillance
Epidemiology
Informatics
Laboratory
What is the definition of epidemiology?
The study of the distribution and determinants of dz frequency in human pops and the application of this study to control health problems
Definition of study
Applies sound methods of scientific inquiry
Definition of distribution
Who, when where
Frequency and pattern of health events in a pop
Rate or risk of dz in pop (to allow valid comparisons across pops)
Definition of determinants
Characteristics that influence whether or not dz occurs (causal or preventive)
Help generate hypotheses
Can be risk factors or protective factors
Definition of dz
May refer to a broad range of health-related events/outcomes
Infectious, chronic dzs, genetic conditions, overall health and well-being
