SES indicates socioeconomic status; SE, standard error PE, physical education; MVPA, moderate to vigorous physical activity.

^†Adjusted for city.

^‡The five physical activity practices were having a PE teacher, providing ≥100 min/wk of PE, having recess supervised by non-classroom teacher, providing ≥20 min/period of recess, and having ≥75 students/supervisor in recess; recess ratio was reverse coded because it was negatively related to MVPA.
