Bold indicates p < .01; italics indicates p < .05; AUCi = area under the curve with respect to increase; MR = maximum response; AUCg = area under the curve with respect to ground; TD exercise = test day exercise; urbanicity was measured at the neighborhood level. Estimates are as reported in the model predicting behavioral problems.
