Multiple Linear Regression Analysis Summary to Predict Elevated A1C Levels Controlling for Activity Level, Race, Education, and Financial Difficulty

Final Model*	b	SE(b)	Beta	P-value
Age	−0.03	0.01	−0.20	.002
Diabetes Duration	−0.94	0.23	−0.26	<.001
PAID	0.02	0.01	0.20	.001
Steps	0.00	0.00	0.11	0.08
Smoking Status	0.64	0.28	0.13	0.03

Note: The dependent variable was A1C; P <.001; F (5,253) = 10.77; age = continuous variable; diabetes duration = dichotomous variable, 0 = ≥10 years or 1 = <10 years; PAID = diabetes distress, continuous variable; steps = number of steps per day, continuous variable; smoking status = dichotomous variable, 0= never/former smoker or 1 = current smoker.

^*Backward-selection method was used; variables with P >.10 removed from models

Model 1: age, education, race, financial difficulty, diabetes duration, PAID, steps, and smoking status.

Model 2: Model 1 (-) financial difficulty.

Model 3: Model 2 (-) education.

Final Model: Model 3 (-) race. (Final Model includes age, diabetes duration, PAID, steps, and smoking status)
