Table 2 Descriptive Statistics of Physical Activity, Sedentary Behavior and Contextual Variables

From: Places where preschoolers are (in)active: an observational study on Latino preschoolers and their parents using objective measures

  1. Notes: a% time refers to % of valid accelerometry time. b% time refers to % of valid accelerometry/GPS unit time. cNumber of children who visited specific locations within the study period varied and is reported in square brackets [n]; d In children whose parents reported they were enrolled in child-care/school/daycare.
