The purpose of the present study was to assess the daily protein uptake and its relationship with sarcopenia, as defined by the Asian Working Group for Sarcopenia (AWGS), among elderly patients with hip fractures.
Forty-seven elderly patients with hip fractures were enrolled in this retrospective observational study. The main outcome measures included protein uptake, muscle mass, and grip strength for sarcopenia in elderly patients. Sarcopenia was diagnosed according to AWGS. Wholebody densitometry was used to measure skeletal muscle mass, and muscle strength was evaluated using handgrip testing.
Of 47 patients with hip fractures (12 men and 35 women), 37 (79%) patients exhibited insufficient protein intake (range, 0.01-0.588 g/kg/day), and 10 (21%) patients exhibited excessive protein intake (range, 1.215-2.121 g/kg/day). The mean daily protein intake was 56.5 g (range, 7.2-136.0 g). Prevalence of low muscle strength (handgrip strength <18 kg in women and <26 kg in men) was detected in 13 (37%) women and 8 (67%) men (P=0.076). Sarcopenia (lower muscle mass and lower muscle strength) was detected in 9 (26%) women and 6 (50%) men (P=0.119). Although lower protein intake was marginally associated with sarcopenia (P=0.189), it was significantly associated with lower grip strength (P=0.042).
The present study demonstrated that insufficient protein intake in elderly patients with hip fractures was common, and lower protein intake was significantly associated with lower muscle strength.
本研究旨在评估髋部骨折老年患者的每日蛋白质摄入量及其与亚洲肌少症工作组（AWGS）定义的肌少症之间的关系。
47例髋部骨折老年患者纳入本回顾性观察研究。主要观察指标包括老年患者肌少症的蛋白质摄入量、肌肉质量和握力。根据AWGS诊断肌少症。采用全身密度测定法测量骨骼肌质量，通过握力测试评估肌肉力量。
47例髋部骨折患者（12例男性和35例女性）中，37例（79%）患者蛋白质摄入不足（范围为0.01 - 0.588 g/kg/天），10例（21%）患者蛋白质摄入过量（范围为1.215 - 2.121 g/kg/天）。每日平均蛋白质摄入量为56.5 g（范围为7.2 - 136.0 g）。13例（37%）女性和8例（67%）男性检测到低肌肉力量（女性握力<18 kg，男性握力<26 kg）（P = 0.076）。9例（26%）女性和6例（50%）男性检测到肌少症（较低的肌肉质量和较低的肌肉力量）（P = 0.119）。虽然较低的蛋白质摄入量与肌少症有轻微关联（P = 0.189），但它与较低的握力显著相关（P = 0.042）。
本研究表明，髋部骨折老年患者蛋白质摄入不足很常见，较低的蛋白质摄入量与较低的肌肉力量显著相关。
