Purpose: The purpose of this study is to analyze the usefulness of the muscle mass-waist circumference ratio (MWR) index as an indicator for diagnosing and predictin gmetabolic syndrome (MetS), with a focus on Korean adults. Method: The study utilized data from the Korea National Health and Ntruition Examination Survey conducted between 2008 and 2011. A total of 9,293 adults were included, and diagnostic criteria for MetS were based on the NCEP ATP Ⅲ guidelines. The MWR index was calculadte by dividing each subject’s muscle mass by their waist circumference. Additionally, demographic factors, health behavior factors, and blood variables were collected. The study performed ROC analysis to calculate the Area Under the Curve (AUC), cut-off value, sensitivity, and specificity for the MWR index in males and females using the MedCalc 19.4. 1 version program. Furthermore, the subjects were categorized inot two groups: the normal MWR (NMWR) group and the abnormal MWR (AMWR) group, based on the cut-off value. Chi-square tests and independent sample t-tests were conducted using the SPSS 25.0 programto assess the differences between each variable between the groups. Additionally, logistic regression analysis was performed to evaluate the risk of MetS based on the MWR group. All statistical significance levels in this study were set at .05. Results: The results of this study are as follows: 1) ROC analysis revaled that the area under the curve (AUC) for the MWR index was 0.627 for males and 0.679 for femeasl. The optimal cut-off value for males was 0.476, and for females, it was 0.491. 2) Comparative analyiss between the NMWR and AMWR groups revealed significant differences in various factors for both mlae and female AMWR groups. These factors included BMI, WC, body fat percentage, levels of TG, TC, LDL-C, fasting blood glucose, insulin, SBP, DBP, and HOMA-IR. 3) The multiple logistic regression analysis, adjusted for various control variables as covariates, showed that the AMWR group had a significantly higher rkis of MetS compared to the NMWR group. Specifically, in men, the AMWR group had a 1.568 times higher risk of metabolic syndrome, while in women, the AMWR group had a 2.167 times higher risk. Conclusion: In conclusion, the MWR index can be a valuable and effectivein dicator for predicting MetS in Korean adults. Consequently, incorporating the MWR index into daily life could prove beneficial in preventing and managing MetS. Additionally, to effectively prevent abdominal obesity and muscle mass loss and maintain the MWR index above the standard value, regular rsetngth training and aerobic exercises are recommended.
