Effect of blood pressure on the mortality of the elderly population with (pre)frailty: Results from NHANES 1999-2004.

ABSTRACT:

Backgrounds

The optimal blood pressure of elderly people with frailty or prefrailty is still unclear. We aimed to explore the relationship between blood pressure and mortality in the elderly with (pre)frailty.

Methods

A total of 528 participants aged 60 years and older were exacted for analyses of the association between blood pressure and mortality from the database of the National Health and Nutrition Examination Survey (NHANES) (1999-2004). Kaplan-Meier curves and log-rank tests were used to investigate the differences in survival between groups. Multivariable Cox regression and restricted cubic spline (RCS) analyses were applied to explore the relationship between blood pressure and mortality.

Results

During the median follow-up time of 116.5 [interquartile range
