The association of post-stroke changes in body mass index with activity of daily living and instrumental activity of daily living trajectories: A multi-cohort analysis

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
