Table 2 Motor constructs and risk of adverse health outcomesa

From: Combinations of motor measures more strongly predict adverse health outcomes in old age: the rush memory and aging project, a community-based cohort study

Predictor Death, HR (95% CI) ADb, HR (95% CI) Disability, HR (95% CI)
Frailty 1.48 (1.27-1.73) 1.56 (1.27-1.92) 1.44 (1.21-1.71)
PSSc 1.53 (1.36-1.72) 1.35 (1.14-1.59) 2.20 (1.90-2.53)
GMSd 0.51 (0.42-0.60) 0.62 (0.49-0.78) 0.39 (0.32-0.47)
  1. aBased on proportional-hazard models that controlled for age, sex and education for each of the three outcomes. Results show the effect for 1 SD unit higher level of physical frailty (1 SD = 0.6 units), parkinsonian sign score (1 SD = 7 points) and global motor score (1 SD = 0.27 units). Higher baseline values for physical frailty and parkinsonian signs score (that is, poorer performance) were associated with an increased risk of adverse health outcomes (HR >1.00) whereas a higher baseline value for global motor score (that is, better performance) was associated with a decreased risk of adverse health outcomes (HR < 1.0).
