Linear mixed models to examine the association between meeting physical activity guidelines at baseline on inflammatory markers over phases 3 to 7.

Model 1; adjusted for age, gender.

Model 2; adjusted for age, gender, smoking, employment grade, BMI, chronic illness.

Physical activity (PA) by time interaction term calculated from meeting the PA recommendation (no=0, yes=1) and time (phase 3 corresponds to time 0, phase 7 to time 1).
