Abstract
Background and Purpose—Although
persistent and significant fatigue affects the daily life of stroke
survivors, there are no population-based studies
examining the prevalence of fatigue in
6-month survivors of ischemic stroke and few studies of predictors of
poststroke fatigue.
Methods—This
article examined data from the Auckland Regional Community Stroke study
conducted in Auckland, New Zealand, in 2002 to
2003. Presence of fatigue was evaluated at 6
months in 613 patients with ischemic stroke using a Short Form 36
Vitality Score
(energy and fatigue) of ≤47. Multivariate
logistic regression analysis was used to determine predictors of fatigue
development
6 months poststroke.
Results—The
prevalence of fatigue was 30% (28% in men and 33% in women). There was a
clear association between increased prevalence
of fatigue and advancing age. The only
baseline variables independently associated with an increased risk of
developing fatigue
at 6 months poststroke were prestroke
incontinence and being of New Zealand European ethnicity. Being
independent and living
alone at baseline were associated with
significant reduction in the risk of being fatigued at 6 months
poststroke. Severe
depression at 6 months was significantly and
independently associated with being fatigued.
Conclusions—The
prevalence of fatigue found in our study is at the lower level of range
reported in other studies. The prevalence of fatigue
increased with advancing age, as found in
most previous studies. Because fatigue can have a negative impact on
stroke recovery,
particular attention needs to be paid to
those who are older, incontinent before stroke, and those who report
severe symptoms
of depression at 6 months after stroke.
