Epidemiological study on hypertension in northern Japan

Aging for 5 years, from 50 to 55 years of age, influenced the various markers in a normotensive group but a similar correlation could not be seen in a hypertensive group. This suggests an impaired control of physiological homeostasis in hypertensive subjects. An increase in body mass index (BMI) is an important predictor in understanding the pathogenesis of hypertension, although the mechanism is uncertain. A reduction in BMI may reduce the risk of high blood pressure.
