Note. RR = Relative Risk; AOR = Adjusted Odds Ratio; Gender (0 = Male, 1 = Female); Race (0 = White, 1 = Non-White); BMI = Body Mass Index.

Pseudo r-square (1 − (Residual Deviance/Null Deviance)); ΔR²_MF = Change in R² between Model 1 and Model 2; ΔΧ² = Chi-Square.

Difference test for comparison of model fit for Model 2 compared to Model 1.

^!= corresponds to a 10-year increase in age.

^&= corresponds to a 5 unit increase in BMI; R2MF = McFadden’s.

^*p < .05.

^**p < .01.

^***p < .001.
