Risk factors are characteristics or conditions that increase the likelihood of developing a disease or health issue. These can include lifestyle choices, such as smoking or poor diet, as well as genetic predispositions, age, and environmental influences. Understanding these factors helps in identifying individuals who may be at higher risk for certain conditions. In public health, risk factors are crucial for prevention strategies. For example, cardiovascular disease can be linked to factors like high blood pressure, obesity, and lack of exercise. By addressing these risk factors, individuals and healthcare providers can work together to reduce the chances of developing serious health problems.
