Key result
Standing for 1 versus 3 minutes resulted in significant differences in postural blood pressure changes (P<0.001), with large coefficients of reproducibility between visits (9.8 to 29.3 mmHg).

Does the duration of standing (1 vs 3 minutes) affect the measurement of postural blood pressure changes in healthy elderly subjects?
p-value: p=<0.001
Postural blood pressure changes in the healthy elderly vary significantly between 1 and 3 minutes of standing, highlighting the need to standardize standing duration when assessing orthostatic hypotension.
Youde et al. (1999) conducted an observational in Healthy elderly (n=22). Standing for 1 and 3 minutes vs. Supine position was evaluated on Differences in postural changes for systolic and diastolic blood pressure between 1 and 3 min of standing (p=<0.001). Standing for 1 versus 3 minutes resulted in significant differences in postural blood pressure changes (P<0.001), with large coefficients of reproducibility between visits (9.8 to 29.3 mmHg).
