Prospective epidemiological studies of blood pressure in a high-salt population in northeastern Japan were investigated along with dietary habits such as miso soup, rice, apple, fish, milk and sake consumption as well as smoking habits.
Blood pressures of the populations in 3 villages were determined once or twice a year by mass surveys from 1954, 1957 or 1958 through 1975. The means and transitions of the personal blood pressure were calculated by regression analysis of the data obtained during each entire period.
The number of persons was 1127 males and 1369 females and the response rate was 98.7 percent. The average number of times of determination of blood pressure for a person was 12.9.
Stepwise multiple regression analyses were run with the means and transitions of systolic and diastolic blood pressure as the dependent variables and the life styles of the population in 1958 as an independent variable based on data of persons whose blood pressures were determined 5 or more times during the entire period. According to the backward stepwise method this study confirmed the positive relationship of age and sake drinking and the negative relationship of apple eating habits to blood pressure.
