Association of Systolic and Diastolic Blood Pressure With All-Cause Mortality Among Community-Dwelling Older Adults: A Prospective Observational Study.
Journal Article (Journal Article)
ObjectivesTo assess the association of systolic blood pressure (SBP) and diastolic blood pressure (DBP) with mortality among older adults in Singapore.
MethodsAssociation of SBP and DBP measured in 2009 for 4443 older adults (69.5±7.4 years; 60-97 years) participating in a nationally representative study with mortality risk through end-December 2015 was assessed using Cox regression.
ResultsHigher mortality risk was observed at the lower and upper extremes of SBP and DBP. With SBP of 100-119 mmHg as the reference, multivariable mortality hazard ratios [HRs (95% confidence interval)] were SBP <100 mmHg: 2.41 (1.23-4.72); SBP 160-179 mmHg: 1.51 (1.02-2.22); and SBP ≥180 mmHg: 1.78 (1.12-2.81). With DBP of 70-79 mmHg as the reference, HRs were DBP <50 mmHg: 2.41 (1.28-4.54) and DBP ≥110 mmHg: 2.16 (1.09-4.31).
DiscussionManagement of high blood pressure among older adults will likely reduce their mortality risk. However, the association of excessively low SBP and DBP values with mortality risk needs further evaluation.
