The SUN cohort 1999-2010.

Physical Functioning: grade in which health problems can interfere with physical activities such as walking, self-care or weight lifting

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

Bodily Pain: pain intensity and its effect on work inside and outside home

General Health: personal belief regarding current health and future perspectives regarding health

(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).
