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 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 |

*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.
