Hypertension is divided into primary hypertension and secondary hypertension. Although primary hypertension increases with age, all people above the age of 3 years suffer from hypertension, only the percentage varies. The survey showed that the prevalence of hypertension in primary and secondary school students was 14.5%, with primary hypertension predominating. The prevalence of hypertension in people aged ≥60 years is 57.0%-60.6%, while the prevalence of hypertension in elderly people aged >70 years can be as high as 80%-90%. Although hypertension is the result of multiple factors and increases with age, people over 45 years of age are more likely to develop hypertension.
