Which of the following is NOT a modifiable risk factor for CHD?

  1. Tobacco use

  2. Hypertension

  3. Age

  4. Diabetes Mellitus

The correct answer is: Age

The correct response identifies age as a non-modifiable risk factor for coronary heart disease (CHD). Non-modifiable risk factors are those that cannot be changed or influenced by lifestyle or medical intervention. Age is one of these factors because the risk of developing CHD increases as individuals grow older, and this is a natural progression of life that cannot be altered. In contrast, tobacco use, hypertension, and diabetes mellitus are all modifiable risk factors. Individuals can choose to quit smoking, manage their blood pressure through lifestyle changes and medication, and control diabetes with dietary modifications and medication, thereby reducing their risk of CHD significantly. Understanding the difference between modifiable and non-modifiable factors is crucial in managing heart disease risk effectively.
