Methods The total of 195 healthy Japanese aged ≥65 years participated (average age, 72.4 ± 4.3y; male, n = 72). The skeletal muscle mass index (SMI) was measured using the bioelectrical impedance analysis (BIA) and the gastrocnemius thickness and collected echo intensity (CEI) were measured using ultrasonography. The low SMI was defined as less then 7.0 kg/m2 in men and less then 5.7 kg/m2 in women, and participants were classified into the low SMI and the normal group. Association of the gastrocnemius thickness with the low SMI was analyzed by the logistic regression analysis after adjusting age, gender, body mass index (BMI), physical performances and CEI. The cut-off value of gastrocnemius thickness to indicate the low SMI was calculated by a receiver operating characteristic curve analysis. Results The low SMI rate was 16.9％ (n = 33). BMI was significantly lower (19.9 vs 22.5 kg/m2; p less then 0.01), the gastrocnemius thickness lower (11.0 vs 13.3 mm; p less then 0.01), and CEI higher (97.5 vs 87.0; p = 0.02) in the low SMI group than those in the normal group. The gastrocnemius thickness was independently associated with the low SMI (OR, 0.584; 95% CI, 0.416-0.818; p less then 0.01). The cut-off value of gastrocnemius thickness was less then 11.6 mm (AUC, 0.83; sensitivity, 0.83; specificity, 0.73; p less then 0.01). Conclusion Gastrocnemius thickness by ultrasonography was associated with low skeletal muscle mass, and the cut-off value to indicate the low skeletal muscle mass was revealed.Background The World Health Organization's active ageing model is based on the opti
