Note: Values represented are hazard ratios (95% confidence intervals) in adults aged 60 y and older. Model 1: no adjustment; Model 2: Model 1 adjusted for age, sex, race, poverty income ratio, and smoking; Model 3: Model 2 adjusted for diabetes mellitus, congestive heart failure, non-skin cancer, coronary artery disease, arthritis, physical activity, and smoking status. ALM = appendicular lean mass; BF = body fat.
