In bold variables with % CIE equal or higher than 10% compared with the crude model (forward selection process).

OR: Odds ratio. 95%CI: 95% Confidence Intervas. BMI:Body Mass Index. T2D: Type 2 Diabetes. CIE: Change-in-estimate.

^∗International Diabetes Federation classification (>90 cm in male: High risk- >80 cm in female: High risk).

^∗∗World Health Organization classification (>94 cm in male: High risk - >90 cm in female: High risk).

^∗∗∗World Health Organization classification Normal (IMC ≥18.5–24.9 kg/m²) – Overweight (IMC ≥25 kg/m²) - Obesity (IMC ≥30 kg/m²)

^⨍Forward selection process: Note that the crude ORs are unadjusted for the main effect only of the Risk of T2D on the setting.

^⨎It includes only variables from forward and backward selection processes.
