Data are means ± standard deviation. Analyses were performed using mixed models adjusted for baseline PA, BMI, race, age, and education.

^¶Full models were performed, and interaction terms from full models are displayed above. Interaction terms were removed and main effects models were rerun; time and group effects displayed above represent those from main effects models.
