  Hypertension is a global health concern with an increasing prevalence,
underscoring the need for effective monitoring and analysis of blood pressure
(BP) dynamics. We analyzed a substantial BP dataset comprising 75,636,128
records from 2,054,462 unique patients collected between 2000 and 2022 at Emory
Healthcare in Georgia, USA, representing a demographically diverse population.
We examined and compared population-wide statistics of bivariate changes in
systolic BP (SBP) and diastolic BP (DBP) across sex, age, and race/ethnicity.
The analysis revealed that males have higher BP levels than females and exhibit
a distinct BP profile with age. Notably, average SBP consistently rises with
age, whereas average DBP peaks in the forties age group. Among the ethnic
groups studied, Blacks have marginally higher BPs and a greater standard
deviation. We also discovered a significant correlation between SBP and DBP at
the population level, a phenomenon not previously researched. These results
emphasize the importance of demography-specific BP analysis for clinical
diagnosis and provide valuable insights for developing personalized,
demography-specific healthcare interventions.
