Abstract: A system for assessing risks of T2DM complications includes: a data acquisition module obtaining and inputting assessment parameters of a patient with T2DM into a risk assessment module; and the risk assessment module inputting the assessment parameters into a number of risk equations and using it to calculate risk values of the complication occurring after a period of time. The risk equation for all diabetic complications (i,j) is: ra(t,i,j)=1?exp{[H(t0)?H(t1)]Ca(t,i,j)} ra(t, i, j) is the risk value for the patient to develop the complication j from the current disease i at age t. t0 is an age of one patient at a state of the disease i. t1 is an age of the patient after the period of time. t is an age between t0 and t1. H(t0) and H(t1) are hazards of the complication occurring at the age t0 and the age t1, respectively.
