Linear Regression Analyses for Effect of BMI on Relation of Self-report and Performance-based Measures

	Model 1		Model 2
	Beta coefficient	p-value	Beta coefficient	p-value
Dependent Variable – Gait Speed
Self-Report Measure of Physical Function	.621	<.001	.367	.026
Body Mass Index	—	—	−.348	.034

Model 1: adjusted R²= .373, F= 30.17, p < .001, Gait Speed = .01 (LLFDI) + .53

Model 2: adjusted R² = .419, F = 18.66, p< .001, Gait Speed = .006 (LLFDI) – .01 (BMI) + 1.1
