As society has changed, so has the way in which parents spend time with their children. Parents' ability and willingness to take their children outdoors can influence children's opportunities for play and physical activity. This study aimed (1) to quantify preschool-aged children's parent-supervised outdoor play frequency and (2) characterize children who are most at risk for less frequent parent-supervised outdoor time. The authors recommend improving efforts to increase active outdoor play particularly for children who are girls and nonwhite.
