Anthropometric Variables as Mediators of the Association of Changes in Diet and Physical Activity With Inflammatory Profile.

Background: Mechanisms underlying the associations of high levels of physical activity (PA) and adherence to the Mediterranean diet (MedDiet) with a better inflammatory profile remain unclear. Our objective was to assess the mediating role of changes in body mass index (BMI) and waist circumference (WC), as markers of body fat in the association of changes in PA and adherence to the MedDiet, with changes in the inflammatory profile.

Method: This study included 489 adults, aged 55-75 years, from the PREDIMED-Plus multicenter lifestyle intervention trial.
