is the unstandardized regression coefficient, and is the standardized regression coefficient. † cm for men and cm for women served as the reference group; kg/m2 served as the reference group. Abbreviations: BMI: body mass index; WC: waist circumference; HRV: heart rate variability; HF: high frequency; LF: low frequency; LF/HF: low- to high-frequency power ratio; VLF: very low frequency; TP: total power; SDNN: standard deviation of normal-to-normal interval.
