Table 4 Multiple regression coefficients for OPQOL score among robust and frail participants.

From: Dimensions and correlates of quality of life according to frailty status: a cross-sectional study on community-dwelling older adults referred to an outpatient geriatric service in Italy

Variables Unstandardized Coefficient
(95% CI)
Collinearity
Tolerance
Robust participants ( n = 72)   
BADL score 1.90 (-0.90 to 4.69) 0.48
IADL score 0.64 (-1.13 to 2.40) 0.31
MMSE score 0.34 (-0.52 to 1.19) 0.45
Body Mass Index (Kg/m2) 0.89 (0.17 - 1.60) 0.95
Frail participants ( n = 78)   
Model without GDS score ( n = 78)   
Age (years) 0.49 (0.01 - 0.99) 0.97
Depression -0.84 (-6.76 to 5.09) 0.97
Model with GDS score ( n = 65)   
Age (years) 0.55 (0.02 - 1.08) 0.96
GDS score -0.50 (-0.91 to -0.09) 0.96
  1. Notes: Bold values are significant at p < 0.05; Models are adjusted for age; "Robust participants" model adjusted R squared = 0.22; "Frail participants" model (with GDS score) adjusted R squared = 0.15.
