Comparison of body composition between patients admitted to convalescent rehabilitation and long-term care wards.

[Purpose] This study aimed to assess the differences in body composition, including phase angle, extracellular water-to-total body water ratio, and skeletal muscle index, between patients in convalescent rehabilitation and long-term care wards. Understanding these differences is essential for tailoring patient care and rehabilitation strategies given that body composition plays a key role in recovery and functional outcomes. [Participants and Methods] In total, 160 patients (73 males and 87 females) in convalescent rehabilitation wards and 26 patients (9 males and 17 females) in long-term care wards participated in this study. Body composition, height, and weight were measured using an InBody S10 device, which allows measurements in both seated and lying positions. [Results] Significant differences in phase angle, extracellular water-to-total body water ratio, and skeletal muscle index were observed between patients in the convalescent rehabilitation and long-term care wards, with larger differences noted among female participants. Specifically, the skeletal muscle index was lower in the patients from long-term care wards, suggesting reduced muscle mass in this group. [Conclusion] Body composition differed between patients in the convalescent rehabilitation and long-term care wards. These findings highlight the need for personalized care and rehabilitation based on body composition to improve patient outcomes.
