Death and total number of participants are presented as unweighted number.
DSST, Digit Symbol Substitution Test, a cognitive test of processing speed; CMD, cardiometabolic disease; HR, hazard ratio; CI, confidence interval. Model 1 was adjusted for age, sex, education, poverty income ratio (PIR); Model 2 was additionally adjusted for physical activity, balance, smokers, alcohol use, CRP and history of cancer; Model 3 was further adjusted for the history of cardiovascular and cerebrovascular diseases (CVD) and cardiometabolic disease risk factors (CMDRF).
