1% of women were classified as having sarcopenia. The participant characteristics by the sarcopenia status in each sex are shown in Table?1. Those with sarcopenia were older and had smaller body size compared with those without sarcopenia in each sex (all P? http://www.selleckchem.com/products/BI6727-Volasertib.html were physically less active in each sex. Chronic medical conditions were in general more prevalent in those with sarcopenia, and a statistically significant difference was observed for hypertension in women, stroke in men and osteoporosis in both sexes. Serum albumin was significantly lower in those with sarcopenia in each sex. Table?2 shows the correlation between each component of sarcopenia and the candidate variables. SMI was correlated with all the variables, with the highest correlation coefficient observed with calf circumference in each sex. Usual gait speed was most highly correlated with age, followed by grip strength and calf circumference in the order of the magnitude of correlation, and this finding was consistent in both sexes. Visual inspection of the restricted cubic spline plots and the Wald test for linearity suggested that the variables were linearly associated with the logit of sarcopenia probability, except for grip strength in both sexes and upper arm circumference in women (data not shown). However, neither dichotomization nor transformation improved the model fit, and we decided to use linear terms of these variables in the development of statistical models. Table?3 shows the unadjusted and adjusted associations between sarcopenia and the variables. In bivariate analysis, all the variables http://www.selleckchem.com/products/cb-839.html were significantly associated with sarcopenia. In multiple logistic regression with all the variables (full model), age was positively, and grip strength and calf circumference were inversely associated with sarcopenia, whereas BMI, thigh circumference and upper arm circumference were not significantly associated. Variable selection resulted in the selection of age, grip strength and calf circumference, and the three selected variables were significantly associated with sarcopenia http://www.selleck.cn/products/wnt-c59-c59.html in multiple logistic regression (restricted model). These findings were consistent in both sexes. The area under the ROC curve of the full model was 0.940 (95% confidence interval [CI] 0.920�C0.959) for men and 0.910 (95% CI 0.888�C0.932) for women, showing excellent discriminative ability. The area under the ROC curve of the restricted model (0.939 with 95% CI 0.918�C0.958 for men and 0.909 with 95% CI 0.887�C0.931 for women) was not significantly different from that of the full model in both sexes (P?=?0.71 for men, 0.43 for women). Assessment of internal validity showed that discriminative ability of the restricted model is expected to be good in similar populations (area 0.937 for men, 0.907 for women). 1.21 (1.17�C1.26) 1.07 (1.02, 1.12) 1.07 (1.02, 1.12) 1.16 (1.13, 1.20) 1.10 (1.05, 1.14) 1.09 (1.04, 1.13) 0.68 (0.63�C0.74) 0.96 (0.78, 1.18) 0.82 (0.78, 0.87) 0.
