SFP, Spanish Food Pyramid; EPIC, European Prospective Investigation into Cancer and Nutrition; ref., reference category; WC, waist circumference.
Model 1: adjusted for age (years), energy intake (kJ/d (kcal/d)) and sex (in models combining men and women).
Model 2: further adjusted for smoking status (never, former, current smoker), educational level (none, primary, secondary, professional school, university degree, missing), misreporting of energy intake (under-reporters, acceptable reporters and over-reporters) and sex (in models combining men and women).
Model 3: further adjusted for WC (cm).
