Relationship between alcohol consumption, body weight, family history of hypertension and blood pressure in young adults.

It is not clear why blood pressure rises with age in civilized countries. We examined the relationship between alcohol consumption, obesity, family history of hypertension and blood pressures at medical checkups in 534 male office workers, aged 20 to 40. The results in two age groups, 20-30 and 31-40, are as follows. Those who drank heavily (greater than 60 ml of ethanol) the previous night and/or habitual heavy drinkers (greater than 60 ml/day) had the highest blood pressure. Obese workers had higher blood pressure. Subjects with a family history of hypertension had higher blood pressure. The frequencies of heavy drinkers and obesity were higher in the group aged 31 to 40 than in the other group. These factors might contribute to the blood pressure elevation with age. 5) A histogram of the first readings of systolic blood pressure showed a bimodal distribution only in persons with a family history of hypertension.
