Summary of Baseline Characteristics by Falls Trajectory Profiles Derived From Group-Based Trajectory Modeling (The MOBILIZE Boston Study, No. = 765^a).

aForty four of the 809 older adults were missing data and therefore excluded from the analysis; bEstimated from Group-Based Trajectory Modeling (GBTM) [18]. cGlobal test: χ2 or Fisher's exact test for binary variables; analysis of variance for continuous variables. dBody mass index is calculated as weight in kilograms divided by height in meters squared. eMini-Mental State Examination (MMSE) cut off point for cognitive impairment [11], [12]. fPhysical activity tertiles measured using the Physical Activity Scale for the Elderly [15]. gBalance score was based on 4 progressively difficult stands: feet side by side, semi-tandem, tandem, and 1-leg stand [17]. hSlow gait speed (m/s) is the lowest 25% based on time of lowest of 2 usual-paced 4-meter walks [17]. iHighest quartile (slowest performance) of time to complete 5 repeated chair stands [17].
