This study aimed to assess the association between skeletal muscle mass index and falls in patients with functional impairment.
This retrospective cohort study was implemented at a convalescent rehabilitation ward. Patients with no measurement of skeletal muscle mass index and bed-ridden patients were excluded from this study. Patients were dichotomized into the low skeletal muscle mass index group and the high skeletal muscle mass index group. The occurrence of fall was assessed according to skeletal muscle mass index groups.
Of the 327 included patients, 231 (71%) were assigned to the low skeletal muscle mass index group. In total, 66 patients (20%) experienced at least one fall, and a total of 102 falls occurred. The incidence of falls for the low skeletal muscle mass index group was not significantly greater than that for the high skeletal muscle mass index group (4.9 per 1000 patient-days vs. 4.5 per 1000 patient-days, P = 0.9). Low skeletal muscle mass index was not significantly associated with one or more incidents of falls (odds ratio [95% confidence intervals] = 0.6 [0.3-1.17]).
This study found that skeletal muscle mass index was not significantly associated with falls in patients undergoing convalescent rehabilitation.
本研究旨在评估骨骼肌质量指数与功能障碍患者跌倒之间的关联。
这是一项在康复病房进行的回顾性队列研究。排除了未测量骨骼肌质量指数和卧床不起的患者。将患者分为低骨骼肌质量指数组和高骨骼肌质量指数组。根据骨骼肌质量指数组评估跌倒的发生情况。
在 327 名纳入的患者中，231 名（71%）被分配到低骨骼肌质量指数组。共有 66 名患者（20%）至少发生了一次跌倒，共发生了 102 次跌倒。低骨骼肌质量指数组的跌倒发生率与高骨骼肌质量指数组无显著差异（每 1000 个患者日 4.9 例 vs. 每 1000 个患者日 4.5 例，P=0.9）。低骨骼肌质量指数与一次或多次跌倒事件无显著相关性（优势比[95%置信区间] = 0.6 [0.3-1.17]）。
本研究发现，骨骼肌质量指数与接受康复治疗的患者的跌倒无显著关联。
