What is Epidemiology?
A field of science which is concerned with the factors and conditions that determine the occurrence and distribution of health, disease, defect, disability, and death among groups of individuals
-
What's involved in epidemiology?
- Identify deviations: Is there more than expected?
- Provide data:
- Prevention and control:
-
Why epidemiology?
Study the patterns and trends in human populations relative to time, place, and persons for the purpose of preventing disease, and maintaining & promoting health.
-
Definition of terms:
- Host: one who gets the disease and displays symptoms
- know age, sex, and other demographics.
- know diseases nutrition, genetics, etc.
- know risks for aquiring disease
- know hosts' health habits, ie hygien, nutrition, occupation, etc.
- Agent: the pathogen that causes disease
-
Measures of morbidity/mortality
- Rate: # of events/population size and dimension of time
- Proportion: # deaths from one event/total # deaths
-
What is the difference between incidence vs prevalence?
- Incidence Proportion: reflects the cumulative effect of the incidence over time: also called the cumulative incidence rate (risk = incidence rate + length of time population is at risk). Measure of NEW cases. Is a snapshot of the current situation.
- Prevalence Proportion: Measure of existing disease in a population at a particular time: # existing cases/current population.
- --Includes both NEW AND OLD.
- Epidemic: rate of event exceeds the usual level.
-
Mortality terms
- Crude Mortality rate: Proportion of a population that die from any cause/#population
- Age-specific rate: # deaths of an age group/#population
- Case Fatality rate: Cause-specific rate
- Infant Mortality rate: # infant deaths before 1 yr of age in a year/number of live births in the same year. First indicator of health risks for a population.
- Neonatal mortality rate: # infant deaths from birth to 28 days in a year/#live births
