Objective: Little data are available on the association between obesity and high blood pressure in elderly individuals, particularly in subjects over 80 years of age. The aim of the present study was to determine the association between body mass index (BMI) and blood pressure in 80-year-old subjects. Methods: This study was part of the 8020 Data Bank Survey, which was designed to collect the baseline data of systemic and dental health conditions in 80-year-old subjects. We studied the cross-sectional association of BMI with blood pressures in 645 Japanese (258 men and 387 women), who were 80 years old. Results: Mean systolic blood pressure rose from 146.6 mmHg in the first quintile of BMI to 147.5 mmHg in the second, 150.3 mmHg in the third, 151.6 mmHg in the fourth, and 156.4 mmHg in the fifth quintiles (test for trend, P=0.006). Mean diastolic blood pressure rose from 75.8 mmHg in the lowest quintile of BMI to 81.8 mmHg in the highest (test for trend, P=0.002). We performed multiple regression analysis, controlling for factors known to influence blood pressure values, such as sex, alcohol intake, current smoking status and serum glucose, total cholesterol and creatinine concentrations. The association between BMI and systolic and diastolic blood pressure, respectively, was highly statistically significant in all analyses. Conclusion: These results show that a close relationship is present between obesity and high blood pressure, even in very old subjects.
