Epidemiology Final exam review
questions with correct answers
mortality rate - CORRECT ANSWER✔✔-Total no of deaths from all
| | | | | | | | | |
causes in year/No of persons in the population at midyear
| | | | | | | | |
*time must be specified*
| | |
cause specific mortality rate - CORRECT ANSWER✔✔-- limiting the rate
| | | | | | | | | |
of death to a certain disease
| | | | |
- No of deaths from lung cancer in one year/ No of persons in the
| | | | | | | | | | | | | | |
population at midyear | |
case-fatality rate - CORRECT ANSWER✔✔-- % of people who have a
| | | | | | | | | | |
certain disease die within a certain time after diagnosis
| | | | | | | |
- measure severity of the disease
| | | | |
- No of individuals dying during a
| | | | | |
specified period of time after disease
| | | | |
onset or diagnosis/No. of individuals with the specified disease
| | | | | | | |
morbidity - CORRECT ANSWER✔✔-usually refers to the incidence of
| | | | | | | | |
disease in the population
| | |
, absolute risk - CORRECT ANSWER✔✔-- incidence of a disease in a
| | | | | | | | | | |
population
- indicate the magnitude of the risk in a group of people with a certain
| | | | | | | | | | | | | | |
exposure, but because it does not take into
| | | | | | |
consideration the risk of disease in nonexposed | | | | | |
individuals
relative risk formula - CORRECT ANSWER✔✔-(risk in exposed)/(risk in
| | | | | | | | |
nonexposed)
relative risk - CORRECT ANSWER✔✔-probability
| | | |
of developing a disease in exposed people compared to the probability
| | | | | | | | | | |
of
developing a disease in nonexposed people, - ratio of the two
| | | | | | | | | | |
probabilities.
- used in COHORT studies
| | | |
how to interpret relative risk - CORRECT ANSWER✔✔-- RR= 1: no
| | | | | | | | | | |
association
- RR>1: positive association, possibly causal
| | | | |
-RR<1: negative association, possibly protective
