Abstract
Gait speed (GS) can predict adverse health outcomes. However, an understanding of its associated factors is still limited and with some controversy. The objective of this study was to identify adverse health outcomes related to the decline in gait speed in community-dwelling older adults. This is a cross-sectional study that evaluated records of chronic diseases and hospitalization in the last year, polypharmacy, and gait speed. Logistic regression analysis was used to estimate the effects of each independent variable on the chance of older adults presenting a decline in gait speed (GS<0.8 m/s) (α=5%). In total, 5,501 older adults participated. Brazilian older adults with heart diseases (OR=2.06; 1.67-2.54 CI), respiratory diseases (OR=3.25; 2.02-5.29 CI), rheumatic (OR=2.16; 1.79-2.52 CI) and/ or depression diseases (OR=2.51; 2.10-3.14 CI); hospitalized in the last year (OR=1.51; 1.21-1.85 CI) and under polypharmacy (OR=2.14; 1.80-2.54 CI) were associated with lower gait speed. Thus, the results showed that those with gait speed lower than 0.8 m/s are at higher risk of some adverse health events. Therefore, it is suggested that gait speed should not be neglected in the evaluation in community-dwelling older adults, including basic health care.
