[Relation of the difference between blood pressure before and after 5 minutes' rest to blood pressure status one year later in an epidemiological setting].
The relationship of the difference between blood pressures before and after 5 minutes' rest (before minus after) to resting blood pressures one year later was studied on 439 subjects, aged 35 to 44 years, not being treated for hypertension, in an epidemiological setting. Multiple regression analysis was applied to systolic (SBP) and diastolic blood pressure (DBP) separately. Both the resting SBP level and the SBP difference were significant predictors of the resting SBP one year later in both sexes. For resting DBP one year later, the resting DBP level and DBP difference were found to be significant in females. Multiple logistic analysis was used to identify the factors which predict development from normotension to above borderline hypertension one year later. The SBP difference as well as the resting DBP level were significant predictors in males. These findings suggest that BP difference between before and after 5 minutes' rest may be an important indicator of subsequent BP status, and therefore there would be value in measuring blood pressure before as well as after rest with particular attention to BP difference.
