Note. All models adjusted for age, gender, marital status, ethnicity, living situation (community dwelling vs. retirement living), educational attainment, study site (Seattle vs. Baltimore), years in current location, number of key medical conditions, and lower-extremity functions. All models also included block group number as a random effect. CI = confidence interval; OR = odds ratio.

^aBased on multi-level linear models.
