Final: Lecture 10 Flashcards
Attack Rate
Same as incidence
Incidence
# new cases of disease/# persons at risk of the disease *Always subtract out those that are immune or already have the disease
Incidence Rate
# new cases of disease/person-time at risk of the disease *Always subtract out those who are immune or already have the disease
Incidence Density
# new cases of disease/person-time people were "at risk" for the disease *Cumulative rate EX: Tendonitis...count first occurrence for an individual only
Cumulative Incidence
new cases of disease/# of persons at risk of disease
- Always subtract out those who are immune or already have disease
- Not precise for dynamic populations
Prevalence
existing cases of disease/# of persons in population
Point Prevalence
Prevalence at any given point in time
EX: January 28
Period Prevalence
Prevalence over a certain length of time
EX: During 1988
Person-Time
Total time people were “at risk” for the disease
Attributable Risk
Difference in rate of condition between an exposed population and an unexposed population
Indirect Rate Adjustment
Use standard rates and apply them to our comparison populations
Direct Rate Adjustment
Using standard population and specific rates from the comparison population
Case Fatality
of cause specific deaths/# of cases of disease
Fertility Rate
of live births/1,000 women of childbearing age (15-44)
Live Birth Rate
live births/1,000 population
