Functional performance indicators associated with hypertension in older people

Abstract

Introduction During aging, changes occur in the human body that increase the probability of arterial hypertension which can potentiate deleterious effects on functional performance. Objective To analyze the association of functional performance indicators with hypertension in older people. Methods An epidemiological, population-based, cross-sectional survey was conducted with 209 older adults (58.40% women). Functional performance was assessed by the following tests: handgrip strength; chair stand test; arm curl test; timed up and go (TUG); sit and reach test; and step in place test (SPT). Diagnosis of arterial hypertension was self-reported. Results The prevalence of hypertension was found to be 58.90% (males: 51.70%; females: 63.90%). It was also observed that the hypertensive individuals of both sexes had worse performance in SPT and TUG (p < 0.05). Furthermore, it was found that each additional second for TUG increased by 11% the probability of hypertension in men (PR:1.11; 95%CI: 1.03-1.20) and by 7% in women (PR: 1.07; 95%CI: 1.04-1.12), while each step performed in the SPT decreased the probability for the outcome by 2% (men and women = PR: 0.98; 95%CI: 0.97-0.99). Conclusion TUG was found to be positively associated with hypertension, while SPT was inversely associated with hypertension.
