This study investigated the association between diabetes status and low grip strength (LGS) among Korean adults aged 40 years and older using data from the 2024 Korea National Health and Nutrition Examination Survey (KNHANES). A total of 3,488 participants were included after excluding individuals with missing data. Diabetes status was classified as normal, pre-diabetes, or diabetes based on fasting plasma glucose, glycated hemoglobin (HbA1c), physician diagnosis, and diabetes treatment status. LGS was defined according to the Asian Working Group for Sarcopenia 2019 criteria (<28 kg for men and <18 kg for women). Sociodemographic factors, health behaviors, and body mass index were considered as covariates. Complex sample multinomial logistic regression analyses were performed to evaluate the association between diabetes status and LGS. The prevalence of LGS increased progressively across diabetes status groups, with rates of 3.9% in the normal group, 4.4% in the pre-diabetes group, and 9.8% in the diabetes group (p<.001). In the crude model, individuals with diabetes had significantly higher odds of LGS compared with the normal group (OR=2.714, 95% CI: 1.847–3.988, p<.001). After adjusting for sociodemographic factors, health behaviors, and body mass index, diabetes remained independently associated with LGS (OR=1.893, 95% CI: 1.226–2.922, p=.004). However, pre-diabetes was not significantly associated with LGS in the fully adjusted model. These findings suggest that diabetes is independently associated with low grip strength among Korean adults aged 40 years and older. Grip strength assessment may serve as a practical functional screening tool for identifying individuals with diabetes who are at increased risk of functional decline and may benefit from early exercise and rehabilitation interventions.
