Abstract

Background
The prevalence of impaired fasting glucose (IFG) in Korea is increasing. Few studies have investigated the relationship between handgrip strength (HGS) and type 2 diabetes among Koreans; however, no study has investigated the relationship between IFG and HGS among Koreans. Therefore, we examined the relationship between relative IFG and HGS to evaluate HGS as a marker of prediabetes.
Methods
This cross-sectional study analyzed data from participants aged 20 years or older (n=9,190) who did not have diabetes and had had their body mass index, fasting plasma glucose (FPG), and HGS measured in the 2016–2017 Korea National Health and Nutrition Examination Survey. The association between relative HGS and IFG was analyzed using complex sample logistic regression analyses after adjusting for age, education, strengthening exercise, aerobic exercise, smoking, excessive drinking, and chronic diseases.
Results
The prevalence of IFG was 31.5 (0.9)% and 19.6 (0.7)% for men and women, respectively. According to the increase in quartile of relative HGS, FPG and HbA1c significantly decreased in both men and women (Ptrend<0.001). In multivariate logistic regression, the odds of IFG significantly decreased with the increase in quartile of relative HGS in both men and women (Ptrend=0.001 for men, Ptrend=0.002 for women).
Conclusion
This population-based, nationally representative study suggests that higher relative HGS is associated with a decreased risk of IFG for both men and women.
