Objective: To examine the relative contribution of psychologic factors
and physical symptoms to the variance in fatigue in older women with
heart failure. Methods: Eighty women who had been hospitalized in the
previous 12 months for heart failure were interviewed, Fifty-seven wom
en completed second interviews 18 months after the first interview. Re
sults: Fatigue was the most frequently occurring physical symptom at b
oth measurement times, and it significantly increased with time. Other
physical symptoms contributed uniquely to the variance in fatigue at
both measurement times, but psychologic factors did not, At time 1, sl
eep difficulties, chest pain, and weakness each explained unique varia
nce in fatigue. At time 2, dyspnea was the only variable that explaine
d unique variance in fatigue (9%), Dyspnea also explained a significan
t portion of the variance (7%) in time 2 fatigue, when time 1 fatigue
was controlled. Conclusions: Fatigue in older women with heart failure
is related more to other physical symptoms than psychologic factors.
