Relationship between pre-stroke physical activity and symptoms of post-stroke anxiety and depression: An observational study.

Objectives: To explore mechanisms affecting mental health in patients with stroke. The aims were to investigate the association between pre-stroke physical activity and symptoms of anxiety and depression 3 months after stroke, and to investigate how self-reported physical activity changed from before to 3 months after the stroke. Design: Secondary analyses of a prospective observational multicentre study. Patients: Stroke patients from 11 Norwegian stroke units. Methods: Symptoms of anxiety and depression were measured using the Hospital Anxiety and Depression Scale, and physical activity was assessed by self-report. Negative binomial regression was used to analyse associations. Results: The analysed sample consisted of 205 patients; mean age was 74 years (standard deviation (SD) 11.5); 46% were women. Higher activity levels before stroke were associated with fewer symptoms of depression in multivariable analyses with regression coefficient of 0.84 (95% confidence interval 0.73-0.97), p= 0.015. Eighty-five (41.5%) patients reported similar activity levels before and after stroke. Conclusion: In this group of patients with mild symptoms of emotional distress, it seems that pre-stroke physical activity might be protective against post-stroke depression, but not anxiety. Many patients with mild-to-moderate stroke report being equally active before and after the stroke.
