Trajectories of objectively measured physical activity and childhood overweight: longitudinal analysis of the IDEFICS/I.Family cohort

Table 4 Association between combination of different weight status according to BMI percentiles at baseline and follow-up and sufficient engagement in MVPA according to different cutoffs at 2-year (N = 3393) and 6-year follow-up (N = 1899) in terms of prevalences of children reaching at least the cutoffs, odds ratios, and 95%-confidence intervals
