Abstract
OBJECTIVE To investigate whether stressful life events (SLEs) can predict post-stroke fatigue (PSF) in patients with acute ischemic stroke (AIS). METHODS This prospective cohort study included data from patients with AIS who were followed up to 2-year interview. PSF was assessed at admission and at 6 (n = 916), 12 (n = 880), and 24 (n = 857) months with the fatigue severity scale (FSS). SLEs were measured with the Social Readjustment Rating Scale questionnaire at 6, 12 and 24 months' interview. RESULTS A significant dose-response association was found between SLEs and FSS score across all examined time-points: compared with those did not experience SLEs, FSS score was higher for those experiencing SLEs ≥3 at 6 months (β 0.53, 95% CI 0.28-0.78), 12 months (β 0.54, 95% CI 0.30-0.78) and 24 months (β 0.48, 95% CI 0.29-0.68). Longitudinal analyses indicated a significantly positive relationship between the number of SLEs and FSS score (SLEs: ≥3 vs. 0, β 0.14, 95% CI 0.09-0.19). Moreover, a distinct interaction of follow-up time and SLE numbers on FSS score was observed (p < 0.05), which means elevated exposure to SLEs during follow-up was associated with a lower rate of fatigue decline. A similar association was found in SLE load analysis. CONCLUSION Patients with severe fatigue were more likely to report increased number of SLEs in the previous 6 months, which could suggest that a non-specific stressful event leads to an extra burden to an already vulnerable psychological system.
