In the in-hospitalization health examination section of one of the Tokyo metropolitan hospitals, 356 adult males, who showed normal results were studied, divided into two groups, the alcohol drinking group and non-drinking group, by occupation, physique, age, family history, hemoglobin content, white and red blood cell count, total serum cholesterol, fasting blood sugar level, Kunkel value, value of GPT, and systolic and diastolic blood pressure. The following results were obtained: 1) Systolic and diastolic blood pressure is significantly high in the group which habitually drink alcohol. 2) Other examinations such as diet habit, family history of cerebral hemorrhage show that those in the group drinking alcohol and with high salt intake, family history of apoplexy and overweight have a significantly high blood pressure. 3) Comparing the blood pressure of the examinees who had health examinations two times (there being 2 to 11-year time interval between the first and second examination), a rise in the blood pressure is shown in the group which has four possible causes of hypertension, that is high salt intake, drinking alcohol habitually, overweight and family history of cerebral hemorrhage. The same tendency is found in the group which has three of the four items (alcohol drinking, high salt intake and family history, or alcohol drinking, high salt intake and ove1·weigh t), and in the group having two items (alcohol drinking habit and high salt intake). Therefore, it is very important to give careful directions to those who habitually drink alcohol, high salt intake, overweight and family history of cerebral hemorrhage, and in whom a rise of blood pressure in the future can be anticipated. This will help control the hypertension and show the way of making good use of the results of health examination.
