Predictors included in the Year 3–7 Model, ranked by their mean Gini importance. Larger Gini values indicate higher relative importance of the predictors to the model's performance. The light red variables relate to the frequency of a physical activity. The orange variables describe the pace, duration, and grade of the physical activity. The yellow variables relate to sun exposure. The green variables describe the type of physical activity, and all other variables describing the location of the activity are in gray
