Fluctuations in blood pressure measurement: the impact of time of day and ethnicity‐ A HABS‐HD Study

Vascular risks including hypertension are significant factors in the development of Alzheimer’s and related dementias . Multiple blood pressure (BP) measurements are commonly used in clinical and research practice to assess this vascular risk. Anecdotal evidence suggests that the first BP measurement taken is more elevated than the second measurement as a participant may be nervous about the study. This study explores if the first measurement is elevated compared to the second and then explores the differences between morning and afternoon measurements.
