Concept of RiskAbsolute Risk
A person's chance of developing a specific disease
over a specified time period.
Example
Observe 100,000 women between the ages of 20 & 29
for one year, ~ 4 would develop breast cancer during
this period
WHAT IS the ONE YEAR ABSOLUTE RISK?
4 per 100,000 or 1 per 25,000

condition.

Example: Risks of Disease
Absolute risk of developing a disease is:
4 in 100 in non-smokers
Relative risk of the disease in increased by:
50% in smokers
What is the absolute risk of smokers
developing this disease?
Absolute increase in risk is 2 (50% of 4)
Absolute risk of smokers developing this
disease is 6 in 100
