The prevalence of metabolic syndrome (MetS) is rapidly increasing with advanced age. Since aging affects sarcopenia and muscle strength, which could, in turns, affect MetS, it is critical to examine the association between MetS and muscle strength in this population. Handgrip strength (HGS) has been introduced as a simple assessment tool for muscular strength. Several studies investigating the association between HGS and the risk of MetS have yield conflicting results. Therefore, this study aimed to investigate the association of MetS and relative handgrip strength (RHGS) in elderly Koreans.


A total of 1,244 (male, 589; female, 655) elderly subjects (age ≥65 years), who participated in the Seventh Korea National Health and Nutrition Examination Survey VII-1 (2016) were analyzed. Participant's HGS, body mass index (BMI), MetS, and its five criteria were measured. Subjects were categorized into four groups based on their RHGS, which was defined as absolute HGS divided by BMI.


The highest quartile RHGS group has a significantly lower prevalence of MetS in both men and women (F=35.16, P<0.001 vs. F=31.78, P<0.001, respectively). Moreover, the odds ratio of MetS was 0.52 times lower (0.52; 95% confidence interval [CI], 0.31–0.85) in the third quartile RHGS than that of the lowest RHGS, and 0.28 times lower (0.28; 95% CI, 0.17–0.47) in the highest RHGS group in women than that of the lowest RHGS group.


Maintaining a high level of HGS may reduce the incidence rate of MetS in elderly Koreans.
