What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Blood pressure assessment (n=7838). Intervention: Sequential blood pressure measurements. Primary outcome: Mean interarm systolic/diastolic differences.

What does this research mean for the field?

Sequential blood pressure measurements initiated on the right arm artificially elevate right-arm readings and potentially overestimate true interarm blood pressure differences. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the appropriateness of sequential measurements in assessing interarm blood pressure differences.

Key result

Sequential right-arm-first BP measurement potentially overestimates interarm systolic differences by up to ~7 mmHg.

n=7,838

Why the study?

Guidelines recommend initial blood pressure assessment on both arms, but because simultaneous measurement devices are often unavailable, the appropriateness of sequential measurements needed evaluation.

Does sequential blood pressure measurement accurately assess interarm blood pressure differences?

Population

7838 participants in Shanghai

Comparison

Sequential blood pressure measurements starting with right arm followed by left arm

Implication

Hypothesis-generating for bilateral BP assessment; does not yet support changes to clinical practice.

Key Points

To evaluate the appropriateness of sequential measurements in assessing interarm blood pressure differences.
Blood pressure measured in Shanghai using an automated system.
Consecutive readings were taken with 1-min intervals on right and left arms.
Threshold for additional reading if difference exceeded 5 mmHg.
Right arm readings were consistently higher; mean interarm systolic difference 4.59 mmHg, diastolic 1.01 mmHg.
With two readings on one arm, differences increased to 6.24 mmHg systolic and 1.45 mmHg diastolic.
With three readings on each arm, differences were 7.22 mmHg systolic and 1.90 mmHg diastolic.

Does sequential blood pressure measurement accurately assess interarm blood pressure differences?

Population

7,838 participants undergoing sequential blood pressure measurements to assess interarm differences.

Exposure

Sequential blood pressure measurement (right arm followed by left arm with 1-min intervals)

Outcome

Interarm blood pressure differences (systolic and diastolic)surrogate

Sequential blood pressure measurement may overestimate interarm differences and lead to more frequent right arm selection, suggesting simultaneous measurements may be necessary.

Limitations

Lack of simultaneous measurement comparison to confirm findings

Sheng et al. (2026) conducted a cross-sectional in Blood pressure assessment (n=7,838). Sequential blood pressure measurements was evaluated on Mean interarm systolic/diastolic differences. Sequential blood pressure measurements starting with the right arm led to potential overestimation of interarm differences, with mean systolic differences ranging from 4.59 to 7.22 mmHg.
