Key result
Supine position linked to ~3 mmHg higher SBP vs sitting.
Why the study?
The impact of patient posture on blood pressure readings in hypertensive patients was not well characterized.
Does supine position compared to sitting position alter blood pressure readings in hypertensive patients?

Does supine position compared to sitting position alter blood pressure readings in hypertensive patients?
Blood pressure readings are significantly higher in the supine position compared to the sitting position in hypertensive patients, with age and sex being independent predictors of this difference.
OBJECTIVE: The objective of this study was to investigate the impact of postures on blood pressure (BP) readings in patients with hypertension. METHODS AND RESULTS: BP was measured in 1,487 hypertensive patients in sitting and supine positions. The systolic (SBP) and diastolic (DBP) BP in supine position was 2.9 +/- 7.8mmHg and 0.9 +/- 5.4 mmHg higher, respectively, than in the sitting position (P <0.001). The greatest difference between supine and sitting SBP was found in those aged between 30 and 39 years (3.6 +/- 6.8 mmHg), and in those who were older than 80 years (5.3 +/- 7.9 mmHg).A greater difference between the supine and sitting DBP was identified in the groups > 60-years of age. Multivariate regression analysis showed that age and sex were independent predictors for the increment of BP in the supine position. CONCLUSION: There is a significant difference between supine and sitting SBP and DBP, with age and sex being the most important predicting factors.

Lu et al. (2008) conducted a cross-sectional in Hypertension (n=1,487). Supine position vs. Sitting position was evaluated on Systolic and diastolic blood pressure (MD 2.9 mmHg (SBP) and 0.9 mmHg (DBP), p=<0.001). Supine position was associated with significantly higher systolic and diastolic blood pressure compared to sitting position (mean difference 2.9 mmHg and 0.9 mmHg higher, respectively; P<0.001).
