Which of the following is a risk factor for cardiovascular disease?

Obesity is indeed a significant risk factor for cardiovascular disease. It is associated with various metabolic issues, such as hypertension, dyslipidemia (abnormal lipid levels), and insulin resistance, all of which contribute to the development of cardiovascular conditions. Excess body fat, particularly around the abdomen, leads to increased levels of inflammation in the body, higher blood pressure, and changes in the way the body processes fats and sugars, all of which can result in a higher risk of heart disease.

When evaluating the other options, low cholesterol levels are typically associated with a lower risk of cardiovascular disease, as high levels of LDL (low-density lipoprotein) cholesterol are a known risk factor. Regular physical activity is protective against cardiovascular disease, promoting heart health and contributing to weight management. A strong family history of longevity does not necessarily increase the risk of cardiovascular disease; in fact, it can suggest a genetic predisposition to better overall health and longevity.
