Multivariable Predictors of MVPA in Sport, All Episodes.

1) Binary: 1 if better-educated parent entered college, 0 if not.
2) Activity levels as described in [24]. MVPA is moderate or vigorous physical activity and refers to non-sporting days only. Participants with sport every day (9, 1.4%) are missing.
3) Team sport defined as any requiring interaction with other participants, in line with [21]
N/A = P ≥0.05 so predictor was removed from the model.,— = not included in initial model
Predictors above the double line (age, study center, parental education, and gender; episode length when predicting zero MVPA, but not when predicting nonzero MVPA) left in model regardless of statistical significance. Nonzero MVPA modeled with negative binomial regression with log of total sporting time as offset, zeroes with logistic regression, both with child as a repeated measure.
