Key Points

  • To examine how changes in body mass index (BMI) post-stroke relate to physical functioning over time.
  • Analyzed multiple cohorts of stroke survivors
  • Monitored changes in BMI post-stroke
  • Assessed daily living activities and physical functioning trajectories
  • Decreased BMI early post-stroke is linked to negative physical functioning outcomes
  • Increased BMI also correlates with adverse trajectories, though to a lesser extent
  • Indicates a need for nutritional and activity management strategies post-stroke

Abstract

Early decreased BMI, and to a lesser extent increased BMI, following stroke could be a marker of long-term adverse trajectories of physical functioning, underlying the importance of nutritional and physical activity management after a stroke.
