Background: Hand grip strength (HGS) is a tool for diagnosing sarcopenia. In this study, we examined some anthropometric and body circumference measurements as determinants for HGS.
Methods: This cross-sectional study was conducted with participants (Mongolians, = 1080, aged 18-70, mean age of 41.2 ± 13.9 years, 33.7% of men) from the "Mon-Timeline" cohort study. To measure HGS, a digital grip strength dynamometer was used.
Results: Mean HGS in men was 40.1 ± 10.4 kg and in women was 24.5 ± 5.6 kg. Correlation analysis showed that the strongest correlation with HGS was height ( = 0.712, < 0.001). Moreover, HGS was inversely correlated with age ( = -0.239, < 0.001) and thigh circumference ( = -0.070, < 0.01), while it was positively correlated with body weight ( = 0.309, < 0.001), neck circumference ( = 0.427, < 0.001), upper arm circumference ( = 0.108, < 0.0001), lower arm circumference ( = 0.413, < 0.0001), and calf circumference ( = 0.117, < 0.0001). In the multivariate linear regression analysis (unstandardized B coefficient, 95% CI), age (-0.159, -0.188; -0.129), sex (-9.262, -10.459; -8.064), height (0.417, 0.357; 0.478), lower arm circumference (1.003, 0.736; 1.270), and calf circumference (-0.162, -0.309; -0.015) were significantly associated with HGS.
Conclusions: When detecting sarcopenia using HGS, it is important to take into account variables such as body height and body circumference.
