Risk factors are characteristics or conditions that increase the likelihood of a negative outcome or event occurring. In research, risk factors are often studied in relation to various health conditions, behaviors, or outcomes to better understand what contributes to their development or impact. Researchers may investigate how different risk factors interact, the strength of their influence, and how they can be modified or managed to reduce the likelihood of negative outcomes. Overall, studying risk factors can help identify potential interventions or strategies for prevention and mitigation.
