Abstract

BACKGROUND

Previous research has demonstrated a correlation between hand grip strength (HGS) and muscle strength. This study aims to determine the relationship between HGS and muscle mass in older Asian adults.

METHODS

We retrospectively reviewed the dual-energy X-ray absorptiometry (DXA) records of 907 older adults (239 (26.4%) men and 668 (73.6%) women) at one medical institution in Taipei, Taiwan, from January 2019, to December 2020. Average age was 74.80 ± 9.43 and 72.93 ± 9.09 for the males and females respectively. The inclusion criteria were: 1) aged 60 and older, 2) underwent a full-body DXA scan, and 3) performed hand grip measurements. Patients with duplicate results, incomplete records, stroke history, and other neurological diseases were excluded. Regional skeletal muscle mass was measured using DXA. HGS was measured using a Jamar handheld dynamometer.

RESULTS

Total lean muscle mass (kg) averaged 43.63 ± 5.81 and 33.16 ± 4.32 for the males and females respectively. Average HGS (kg) was 28.81 ± 9.87 and 19.19 ± 6.17 for the males and females respectively. In both sexes, HGS and regional muscle mass consistently declined after 60 years of age. The rates of decline per decade in upper and lower extremity muscle mass and HGS were 7.06, 4.95, and 12.30%, respectively, for the males, and 3.36, 4.44, and 12.48%, respectively, for the females. In men, HGS significantly correlated with upper (r = 0.576, p < 0.001) and lower extremity muscle mass (r = 0.532, p < 0.001). In women, the correlations between HGS and upper extremity muscle mass (r = 0.262, p < 0.001) and lower extremity muscle mass (r = 0.364, p < 0.001) were less strong, though also statistically significant.

CONCLUSION

Muscle mass and HGS decline with advancing age in both sexes, though the correlation is stronger in men. HGS measurements are an accurate proxy for muscle mass in older Asian adults, particularly in males.

摘要

背景

先前的研究表明,握力(HGS)与肌肉力量之间存在相关性。本研究旨在确定握力与老年亚洲成年人肌肉量之间的关系。

方法

我们回顾性分析了 2019 年 1 月至 2020 年 12 月期间,台湾台北一家医疗机构的 907 名年龄在 60 岁以上的成年人(男性 239 人(26.4%),女性 668 人(73.6%))的双能 X 射线吸收法(DXA)记录。男性和女性的平均年龄分别为 74.80 ± 9.43 岁和 72.93 ± 9.09 岁。纳入标准为:1)年龄在 60 岁以上,2)进行全身 DXA 扫描,3)进行握力测量。排除重复结果、记录不完整、有中风史和其他神经系统疾病的患者。使用 DXA 测量身体各部位的骨骼肌质量。使用 Jamar 手持式测力计测量握力。

结果

男性和女性的平均总瘦肌肉量(kg)分别为 43.63 ± 5.81 和 33.16 ± 4.32。男性和女性的平均握力(kg)分别为 28.81 ± 9.87 和 19.19 ± 6.17。在男性和女性中,60 岁以后,HGS 和四肢肌肉量都持续下降。男性上肢和下肢肌肉量以及 HGS 每十年下降率分别为 7.06%、4.95%和 12.30%,女性分别为 3.36%、4.44%和 12.48%。男性的 HGS 与上肢(r = 0.576,p < 0.001)和下肢肌肉量(r = 0.532,p < 0.001)显著相关。在女性中,HGS 与上肢肌肉量(r = 0.262,p < 0.001)和下肢肌肉量(r = 0.364,p < 0.001)之间的相关性虽较弱,但也具有统计学意义。

结论

在男性和女性中,肌肉量和 HGS 随着年龄的增长而下降,但在男性中相关性更强。在老年亚洲成年人中,HGS 测量值是肌肉量的准确指标,尤其是在男性中。
