[Effects of age and sex on orthostatic change of blood pressure in normal persons].
Orthostatic change of systolic blood pressure was consecutively recorded using oscillometric method in 140 normal persons aged twenties to eighties and analyzed by age and sex. Systolic blood pressure generally increased after standing. The men, especially over the age of 50, failed to increase blood pressure immediately after standing (initial 1-3 minutes), and then increased. In the women, on the other hand, blood pressure generally increased after standing. The mean ratio of the blood pressure elevation for 10 minutes was higher in the women than in the men over 50 years old. Systolic blood pressure tended to fall immediately after the second supine from standing in both sexes. In conclusion, age and sex may influence orthostatic change of blood pressure.
