Usage tips
Word composition
The word is made up of 'Risiko' (risk) and 'Faktor' (factor). So it literally describes a factor that represents or increases a risk.
EXAMPLE
Ein hoher Cholesterinspiegel ist ein bekannter Risikofaktor.
A high cholesterol level is a known risk factor.
Correct preposition
To express what something poses a risk for, the preposition 'für' (for) is used with the accusative. A 'Risikofaktor' (risk factor) is always a risk factor 'für' (for) something.
EXAMPLE
Bewegungsmangel ist ein Risikofaktor für Herz-Kreislauf-Erkrankungen.
Lack of exercise is a risk factor for cardiovascular diseases.
Typical collocations
'Risikofaktor' (risk factor) is often combined with certain adjectives to describe its strength or importance. Common combinations are 'ein großer/hoher Risikofaktor' (a major/high risk factor), 'ein wesentlicher Risikofaktor' (a significant risk factor), or 'ein zusätzlicher Risikofaktor' (an additional risk factor).

Risikofaktor vs Gefahr
danger
'die Gefahr' and 'der Risikofaktor' are related, but they are not the same thing. 'die Gefahr' is the threatening situation itself or the possibility of harm. 'der Risikofaktor' is an individual circumstance that makes a danger more likely. In medicine, for example, smoking can be a risk factor for a disease; the disease or harm is then the danger. Learners may confuse the words because both have to do with risk. Remember: the Risikofaktor increases the Gefahr; it is not automatically the whole danger.
Risikofaktor
Zu wenig Bewegung ist ein Risikofaktor für viele Gesundheitsprobleme.

Gefahr
