Trajectories of depressive symptoms, ADLs limitations, IADLs limitations, and multimorbidity status from 2002–2010. A Depressive symptoms: class 1 (black line, maintaining low CES-D score) and class 2 (red line, low starting CES-D scores that steadily increased throughout follow-up). B ADLs limitations: class 1 (black line, maintaining low ADLs score) and class 2 (red line, low starting ADLs scores that steadily increased throughout follow-up). C IADLs limitations: class 1 (black line, maintaining low IADLs score) and class 2 (red line, low starting IADLs scores that steadily increased throughout follow-up). D Multimorbidity status: class 1 (black line, maintaining low multimorbidity status), class 2 (red line, maintaining high multimorbidity status throughout follow-up), class 3 (green line, low starting multimorbidity status that increased early), and class 4 (blue line, low starting multimorbidity status that increased late). ADLs, activities of daily living; CES-D, Centers for Epidemiologic Research Depression; IADLs, instrumental activities of daily living
