Question

What is a risk factor?

A. a variable associated with getting a noninfectious disease
B. a variable that cannot be controlled
C. a variable that a person is born with
D. a variable that causes infectious disease

Answer 1

I would say A. is a variable associated with getting a noninfectious disease.

Step-by-step explanation:

A risk factor is any attribute, characteristic, or exposure of an individual that increases the likelihood of developing a disease or injury. A risk factor does not cause infectious diseases. If the wording said "associated" then perhaps D. could be correct. B and C do not make sense.

Answer 2

Answer: A. variable associated with getting a noninfectious disease. Non-infectious diseases are not caused by pathogens and therefore cannot be spread from one person to another. Instead, non-infectious diseases are caused by factors such as genetics, malnutrition, environment and lifestyle. Examples of non-infectious diseases include cancer, Alzheimer's disease and epilepsy.
