All of the following are considered ratios except:
Time
Those members of the population who are capable of developing a disease or condition are
known as:
The Population at Risk
On May 1, 2010, the number of residents of Oklahoma who had been diagnosed with
asthma at any time during their life was A.
The population on June 30, 2010, was B.
During the same year, the number of new cases of asthma was C.
Which of the following expressions represents the incidence rate of asthma (per 100,000)?
None of the above.
True or False: Adjusted rates pertain only to mortality rates.
False
What is the main advantage of using an age-adjusted rate as compared to a crude rate?
The advantage of an age-adjusted rate as compared to a crude rate is that it facilitates

Imagine you are planning health services in a community and you want to know how many
services are needed to care for patients with motor neuron disease. The incidence of motor
, neuron disease is relatively low and the mean survival time is three to five years. Which
measure would be most helpful?Why?
Prevalence, Prevalence quantifies all cases of disease at this point in time. This number will tell
us how many people require health services in the community, and we can plan accordingly.
Using incidence would provide an underestimate of the burden of disease, because it would only
count new cases of disease for that year, instead of all existing cases.
