Association of Y0 AmMedDiet score and treadmill duration (analyzed simultaneously) and ORs of pre-diabetes or diabetes at Y25

	Y25 Pre-diabetes	p Value	Y25 diabetes	p Value
Y0 AmMedDiet score and Y0 treadmill duration, unadjusted
Y0 AmMedDiet score (per 1 SD (2.1 point) increment)	0.92 (0.86 to 0.99)	0.03	0.83 (0.74 to 0.93)	0.001
Y0 treadmill duration (per 1 SD (181.0 s) increment)	0.93 (0.86 to 1.00)	0.06	0.61 (0.54 to 0.68)	<0.0001
Y0 AmMedDiet score and Y0 treadmill duration, adjusted*
Y0 AmMedDiet score (per 1 SD (2.1 point) increment)	1.01 (0.93 to 1.09)	0.84	0.92 (0.81 to 1.05)	0.21
Y0 treadmill duration (per 1 SD (181.0 s) increment)	0.85 (0.75 to 0.95)	0.005	0.72 (0.60 to 0.86)	0.0003

*Adjusted for age, sex, race, field center, physical activity, BMI, education, smoking, and caloric intake.

Data are ORs (95% CIs). The model includes AmMedDiet score, treadmill duration, and the interaction between the AmMedDiet score and treadmill duration (p=0.02 for interaction). The interaction between the AmMedDiet score and treadmill duration was not statistically significant in either of the adjusted models, and so was not included.

AmMedDiet, Americanized Mediterranean diet; BMI, body mass index; Y0, year 0; Y25, year 25.
