The SUN cohort 1999-2010.

Vitality: vitality and energy feelings against tiredness or exhaustion

Social Functioning: grade in which mental health problems can interfere with habitual social life

Role Emotional: grade in which mental health problems can interfere with work activity or with other daily activities

Mental Health: general mental health including depression, anxiety, emotional and behaviour control and general positive effect

(1): Model adjusted for age, sex, smoking (non smoker, current, ex-smoker and missing value), leisure time physical activity (in quintiles of METs-h/wk score), total energy intake (Kcal/day), and baseline BMI (Kg/m2), MUFA, PUFA and, additionally, SFA (TFA intake) or TFA (SFA model).

(2): Model 1 additionally adjusted for adherence to the Mediterranean Diet score (0-8) (excluding SFA/MUFA ratio).
