Final answer:

Step-by-step explanation:
The true statement regarding hypertension in adults is that the etiology of primary hypertension is multifactorial, involving a combination of genetic and lifestyle factors. While smoking is a risk factor, it is not considered the most common cause of hypertension. Hypertension is a persistent elevation of blood pressure in the arteries and is a significant risk factor for various cardiovascular diseases. Obesity, poor nutrition, lack of physical activity, and tobacco use all elevate the risk for hypertension. The condition is known as a 'silent killer' because it usually does not cause symptoms. Strong emphasis should be placed on managing hypertension through lifestyle changes and medication where necessary.
