Abstract Background Effects of fatigue on health in older age are well studied, yet little is known about the clinical relevance energy perception. Aims To explore cross-sectional associations self-reported with physical and mental metrics Health, Aging, Body Composition Study. Methods Participants rated their from 0 to 10; outcome was dichotomized at median (≥ 7 = higher energy). Four domains were assessed: depressive symptoms (Center for Epidemiologic Studies Depression Scale); performance (function: usual rapid gait speed; fitness: 400-m walk time); activity (casual walking, walking exercise, intense exercise); cognitive function (Modified Mini-Mental State Examination Digit Symbol Substitution Test). Covariates bivariately associated entered a multivariable logistic regression model, adjusted demographics, chronic conditions, strength. Results Depressive symptoms, activity, but not cognition, ( p < 0.0005). Younger age, male sex, greater strength, absence conditions predicted 0.001). In [adjusted odds ratio (aOR) 95% CI 0.69 (0.62, 0.76)] times [aOR 0.81 (0.72, 0.91)] inversely energy; speed 1.3 (1.2, 1.4); aOR 1.2 (1.1–1.4)], time spent exercise 1.4 (1.1–1.7)] positively energy. Discussion this cohort range fatigue, perceiving levels may reflect better emotional health. Conclusion Energy should be considered multidimensional assessments age.
