Age factors and hypertension

Hypertension in all ages may appear, but older people with hypertension are the most. Beijing city ever had made investigation, 65 to 74 years old, the incidence of hypertension was above 40%, and the population of hypertensive incidence is around 10%, of which 20 persons under the age of prevalence rate of 3.11%; 20 to 29 years of age to 3.91%; 30 to 39 years of age to 4.95%; 40 to 49 years old for 8.60%; 50 to 59 years of age to 11.38%; 60 to 69 years old for 17.23%. In view of this, along with the growth of the age, risk of suffering from high blood pressure.

Why older people predisposed to hypertension? Its pathogenesis: arterial blood pressure by vascular resistance and elastic effects, and the middle-aged man had, the blood vessels in the body begin to decline, vascular sclerosis, the lumen becomes narrow, arterial elasticity. In addition the age with the growth, the function of the heart is on the decline, the body metabolism is slow, the vascular resistance increased significantly, resulting in elevated blood pressure. Medical research found that, in older adults even without the risk of hypertension, blood pressure measured value also increases with age, from the age of 40, an increase of 10 per year, systolic blood pressure was elevated to 10 mm hg. Therefore, age and hypertension are closely related.

Therefore, in the country of hypertension epidemiology investigation, always put the age as the primary investigation of the factors. For daily health and age over 40 years old people, I advise you to take care of the body, and proper attention to their blood pressure, to prevent the occurrence of hypertension.
