Legend: Walking dysfunction was defined as having “some difficulty,” “much difficulty,” or “unable to do” when “walking for a quarter mile (that isabout 2 or 3 blocks],” “walking up 10 steps without resting,” or “walking from one room to another on the same level.” The sample size here was limited to all persons age 60 and older.

Model 1 is adjusted for age, sex, and race/ethnicity. Model 2 isadjusted for all variables in Model 1 plus history of coronary heart disease, diabetes status, smoking status, hypertension, and hypercholesterolemia. Model 3 isadjusted for all variables in Model 2plus self-rated general health status.
