question
select the correct answer.
which is the best definition of a risk factor?
the combination of quality of life and life expectancy
the average rate of hospital births within a country
a behavior or condition that might lead to disease or injury
a hereditary disease that a person is likely to develop later in life

Explanation:

• The first option defines "health - related quality of life and life expectancy" (like Health - Adjusted Life Expectancy), not a risk factor.
• The second option is about a birth - related statistic (like a measure of maternal or neonatal care access), not a risk factor.
• The third option: A risk factor is something (behavior like smoking, condition like high blood pressure) that increases the chance of getting a disease or injury, so this matches the definition of a risk factor.
• The fourth option describes a hereditary disease (a specific disease with genetic predisposition), not a risk factor (a risk factor is more about increasing the likelihood of disease/injury, not the disease itself).

Answer:

C. a behavior or condition that might lead to disease or injury
