In this study, we first identified some biochemical markers related to sarcopenia among elderly Chinese participants from the WCHAT study and found that participants with sarcopenia had significantly lower FT3, insulin, TP, ALB, PA, A/G ratio, ALT, TG, and VLDL concentrations (P = 0.009 for TP; P = 0.029 for TG; P = 0.030 for VLDL; P < 0.001 for the other biomarkers). The gene discussed is INS; the disease is sarcopenia.
