A risk factor is a condition that increases the likelihood of a negative event occurring. Synonyms for risk factors include vulnerability, susceptibility, predisposition, and hazard. These terms all describe the likelihood or potential for a negative outcome to occur. Vulnerability refers to the possibility of exposure to harm or damage. Susceptibility implies a greater likelihood of being affected by a particular risk. Predisposition implies an inclination or tendency towards a particular negative outcome. Hazard refers to anything that has the potential to cause harm. Identifying risk factors is an important step in understanding potential dangers and developing strategies to mitigate them.
