Physical and mental health were correlated with each other during the acute phase, but not at follow-up. Physical health in the acute phase was associated with physical health at 18 months; likewise, mental health in the acute phase was associated with mental health at follow-up.
Hierarchical multiple regression analyses were conducted to evaluate the extent to which acute phase fatigue predicts HRQoL at 18 months after stroke while controlling for relevant covariates. Each model included age, sex, cohabitation status, and acute phase depressive symptoms.
The model predicting physical health at 18 months also included acute phase physical health to account for baseline functioning, while the model predicting mental health at 18 months included acute phase mental health. As shown in table 4 , acute phase fatigue was a significant predictor of physical health at 18 months, even when accounting for baseline physical health and other relevant variables.
In contrast, acute phase fatigue was not a significant predictor of mental health at 18 months after accounting for baseline mental health table 5. Given the conceptual overlap between mental health and depressive symptoms, the analysis in table 5 was repeated without depressive symptoms as a covariate, but the role of fatigue remained insignificant. The temporal relationships between fatigue and physical and mental health were also examined in the reverse direction to determine whether physical or mental health in the acute phase was predictive of fatigue 18 months later.
Like the models presented in tables 4 and 5 , the reverse models controlled for age, sex, cohabitation status, and depressive symptoms in the acute phase. However, the dependent variable was changed to fatigue at 18 months and the remaining independent variables were changed to acute phase fatigue and either physical or mental health.
This study describes the longitudinal relationship between fatigue in the acute phase after stroke and patients' perceived health 18 months later. In this study, acute phase fatigue did not predict mental health, but was directly related to and predicted lower physical health at month follow-up, even after controlling for sociodemographic variables and the patients' physical health and depressive symptoms in the acute phase.
By controlling for acute phase physical health, the role of acute phase fatigue is distinguished from other characteristics known to predict later physical health, such as prestroke health, comorbidity, stroke severity, and degree of functional impairment. By also controlling for depressive symptoms, which often co-occur with fatigue, these findings indicate that acute phase fatigue is an independent risk factor for poor long-term physical health following stroke and is not only a manifestation of depression.
Moreover, it does not seem that fatigue and physical health are merely changing together over time, since physical health during the acute phase did not predict later fatigue. These findings of acute phase fatigue are generally consistent with those of correlational studies of fatigue later in the recovery period ranging from 3 months to 2 years after stroke.
Thus, our results suggest a stronger connection between fatigue and physical health, in contrast with other findings, 7 which indicate a stronger relationship with mental health. The findings of this study are also consistent with other longitudinal studies that have found fatigue to be associated with subsequent health outcomes.
Two studies have shown that fatigue after stroke either within 6 months or 2 years after stroke predicts death in the following year, even when accounting for other background variables.
Although it is often assumed that factors correlated with fatigue are involved in its development, the results of this study suggest that acute phase fatigue is involved in the development of physical health over time. It may be that fatigue in the acute phase limits patients' participation during a critical, early phase of rehabilitation and thus interferes with long-term recovery.
Our finding indicates that fatigue management ought to be included in clinical guidelines for stroke treatment and rehabilitation. From a clinical perspective, it would be desirable to know whether treatment of acute phase fatigue contributes to better rehabilitation outcomes. It should be noted that the physical health ratings during the acute phase were approximately 1 SD below the norm for the general population. Lower scores on measures of physical health relative to measures of mental health is consistent with previous findings 32 among individuals following stroke.
The results of this study should be considered in light of its strengths and limitations. Use of a validated and established HRQoL measure in both the acute phase and at month follow-up made it possible to control for the patients' physical and mental health in the acute phase when examining acute phase fatigue as a predictor of subsequent outcome. Furthermore, this longitudinal study evaluated the temporal relationships between acute phase fatigue and HRQoL 18 months later, which cannot be examined in cross-sectional studies.
The measure of fatigue FSS-7 used in this study emphasized how a person's level of fatigue interferes with daily life. Other aspects, such as perceptions of fatigue and performance fatigability, 33 also need to be explored in future studies.
This study utilized a systematic sampling approach, and had high participation and retention rates over the course of the study, thereby reducing the risk of sampling or retention bias and increasing generalizability of the findings. Nonetheless, severely depressed patients may have been less likely to participate and thus may be underrepresented in the study sample. Furthermore, patients with recurrent stroke and patients with insufficient cognitive or communication skills were excluded from the study, and thus, the findings cannot be generalized to these patient groups.
Norway also offers comprehensive rehabilitation services as part of the national health care system, and thus findings on health outcomes might not generalize to patients with more limited health care services. A small number of participants did not meet the objective criteria for cognitive status i. However, given the small number and their ability to complete the consent process and questionnaires, it is not expected that their inclusion had an undue influence on the study, and in fact, may have somewhat increased its generalizability.
This study did not include a cognitive assessment at the month follow-up, and thus, the role of this potentially confounding variable could not be evaluated. Finally, data on stroke characteristics were limited to type and general location and the small number of hemorrhagic strokes limited our ability to effectively evaluate the role of stroke type. However, most studies that have included more detailed information on stroke characteristics have not found them to be significant predictors of poststroke fatigue.
This study extends the findings of prior studies showing that poststroke fatigue is likely to persist over time 12 , 30 and to affect later physical HRQoL. This is true not only for patients who experience fatigue later in the recovery period, but also for patients who experience fatigue in the first few weeks following stroke. Thus, future research might focus on developing interventions that target fatigue early in the recovery period, rather than waiting until fatigue has noticeable, and possibly irreversible, effects on physical health.
