Associations between pre-stroke physical activity levels and health-related quality of life 3 months after stroke: A registry-based study (part of PAPSIGOT).

Abstract

Whether pre-stroke physical activity is associated with health-related quality of life after stroke has been sparsely investigated. To explore associations between pre-stroke physical activity and health-related quality of life 3 months after stroke onset. A consecutively collected cohort study with data from registries. Included were adult patients with first stroke in the period 2014-2018 who were hospitalized at any one of the three stroke units in Gothenburg, Sweden. Pre-stroke physical activity was assessed with the Saltin-Grimby Physical Activity Level Scale (SGPALS) after hospital admission for acute stroke. Health-related quality of life was assessed with the EuroQoL 5 Dimensions 5 Level Version (EQ-5D-5L) 3 months after stroke. Data were analyzed with the Kruskal-Wallis test and binary logistic regression. Data were included from 2044 patients; 91% had ischemic stroke, 46% were female, and mean age was 73 years, with mild stroke severity median National Institute of Health Stroke Scale (NIHSS) of 2. Patients who were pre-stroke physically active reported better overall health-related quality of life by the EQ-5D-5L index value, all the domains in EQ-5D-5L, and the EuroQoL-Visual Analogue Scale (EQ-VAS) compared with pre-stroke physically inactive patients (all p < 0.001). Better health-related quality of life 3 months after stroke was associated with pre-stroke light and moderate physical activity: adjusted odds ratio (95% confidence interval), 1.9 (1.5-2.3) and 2.3 (1.5-3.4), respectively. Pre-stroke physical activity is associated with better health-related quality of life 3 months after stroke. For the domains of mobility, self-care, and pain/discomfort, physical activity with higher intensity is even more beneficial.
