Key result
The clinic-daytime ambulatory systolic blood pressure difference was 14 mmHg in young elderly females versus 1 mmHg in old elderly females (P=0.04).
Why the study?
How do clinic and 24-h ambulatory blood pressure levels compare between young elderly (65-79 years) and old elderly (≥80 years) subjects?
Population
108 ambulant subjects aged 65-95 years with no known history of hypertension, recruited from the community…

Larger white-coat effect in young elderly females may influence clinic BP interpretation; leaves open whether ambulatory thresholds require age- and sex-specific adjustment.
Cross-Sectional (n=108)
How do clinic and 24-h ambulatory blood pressure levels compare between young elderly (65-79 years) and old elderly (≥80 years) subjects?
Absolute Event Rate: 14% vs 1%
p-value: p=0.04
The white-coat effect and nocturnal blood pressure dipping decline with advanced age, particularly in females, highlighting age- and sex-specific differences in ambulatory blood pressure profiles.
Fotherby et al. (1995) conducted a cross-sectional in No known history of hypertension (n=108). Young elderly age (65-79 years) vs. Old elderly age (≥80 years) was evaluated on Clinic-daytime ambulatory systolic blood pressure difference in females (p=0.04). The clinic-daytime ambulatory systolic blood pressure difference was 14 mmHg in young elderly females versus 1 mmHg in old elderly females (P=0.04).
