Question

Of the known modifiable factors for CHD in the US, cigarette smoking is perhaps the most important.

A) TRUE
B) FALSE

Answer 1

True. Smoking is correctly identified as one of the most important modifiable risk factors for CHD. Alongside smoking, other lifestyle changes in diet, exercise, and alcohol consumption can also help reduce CHD risk.

Step-by-step explanation:

Of the known modifiable factors for coronary heart disease (CHD) in the US, cigarette smoking is indeed one of the most important. This statement is TRUE. Smoking can significantly increase the risk of developing cardiovascular diseases, such as CHD, because it contributes to the build-up of plaque in arteries, reduces oxygen in the blood, and increases blood pressure.


Besides smoking, other modifiable risk factors include obesity, lack of physical activity, poor nutrition, and excessive alcohol consumption. However, some risk factors like age, gender, and genetics are non-modifiable. A comprehensive approach to reducing the risk of CHD would include addressing all modifiable lifestyle factors.
