Prevalence and Predictors of Poststroke Anxiety

Objective：This study aimed to investigate the prevalence and predictors of poststroke anxiety (PSA) at acute and chronic stage. Methods：PSA was defined as 7 or higher score on Hospital Anxiety and Depression Scale-anxiety subscale within 2 weeks (n=286) and at 1 year (n=222) after the index stroke. Following variables were examined at baseline: sociodemographic characteristics (age, sex, education years, marital status, living alone, and unemployment), risk factor of vascular disease, stroke location on brain imaging, severity of stroke (National Institute of Health Stroke Scale), physical impairment (Barthel Index), etc. These variables were compared by PSA initially using t-test or χ2 test. Those variables shown significant associations (p＜0.05) entered simultaneously to logistic regression analysis for evaluating independent predictive factors. Results：PSA was observed in 27 patients (9.4%) at acute stage, and in 35 patients (15.8%) at chronic stage. Acute PSA was associated with younger age and higher Hamilton Depression Rating Scale (HAM-D) score, and chronic PSA was associated with hypertension and higher HAM-D score. Conclusion：PSA was prevalent and was associated with those variables on poor prognosis of stroke outcome. Therefore, early screening of PSA and referral to proper treatment may reduce stroke burden.
