In which population is the incidence of hypertension highest?

The incidence of hypertension is highest in older adults due to several interconnected factors that affect blood pressure regulation and cardiovascular health as people age. As individuals grow older, there are physiological changes in the vascular system, including arterial stiffness and increased peripheral vascular resistance. Additionally, age-related changes in kidney function can impact the body’s ability to regulate fluid balance and blood pressure effectively.

The prevalence of comorbidities also increases with age, such as obesity, diabetes, and chronic kidney disease, which can contribute to the risk of developing hypertension. Lifestyle factors, including reduced physical activity, dietary changes, and increased stress levels, may also play a role in this population.

Although hypertension can occur in adolescents and younger adults, it is significantly less prevalent in these groups compared to older adults. Middle-aged adults have a higher incidence than younger adults, yet they do not surpass the rates seen in older demographics. Therefore, the highest incidence of hypertension is observed in older adults, making this the correct answer.
