1.5 Age and Sex Differences in the Association of Brachial and Central Blood Pressure Variability with Arterial Stiffness

Both blood pressure variability (BPV) and arterial stiffness (AS) are significantly influenced by age and sex. However, whether the association between BPV and AS differs with age and sex remains unclear. We examined age and sex differences in the association between brachial and central BPV and AS in a cohort of healthy individuals, covering a wide age-span. 24-hour brachial and central blood pressures (Mobil-O-Graph) and aortic pulse wave velocity (aPWV) (SphygmoCor) were measured in 957 healthy individuals (age range: 18–88 yrs; mean age: 46 ± 18 yrs; 45
