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.
