Risk Factor

Explanation:

Risk factor for some disease are the predictors of that disease which does not necessarily cause the disease but may increase the chances of getting it. Hence, risk factors increase the chances of disease occurrence or it may be said that it elevates the frequency of getting the disease in some locality making that a high-risk community. For example, Obesity is a risk factor for getting cardiovascular disease but it is not directly associated with causing the disease. However, those communities in which people are more Obese are considered as high-risk community for cardiovascular disease.

The answer is risk factor: A condition associated with an elevated frequency of disease but not proved to be casual is called a risk factor.

Explanation:

A risk factor is a characteristic or behaviour that creates a higher probability of getting an injury or disease. Although risk factors are presented as separate characteristics, they do not exist or occur alone. They exist hand in hand, and influence each other.
