title: Physical activity of preschool-aged Latino children in farmworker families.
abstract: OBJECTIVE
  To describe time spent in sedentary and moderate-to-vigorous physical activity (MVPA) by children in Latino farmworker families and delineate sources of variation in sedentary and MVPA.
  
  
  METHODS
  Data were from mother-child dyads (N = 248) in Latino farmworker households in North Carolina. Physical activity was assessed using accelerometers; mothers described their children's characteristics and their physical and social environments.
  
  
  RESULTS
  Children spent 6.2 hours/day sedentary (Median=369 minutes), and 6.0 minutes/day in MVPA. Children in Head Start spent more time sedentary, whereas children living where dogs roam freely were less sedentary. Children whose mothers limited screen time spent 2 more minutes in MVPA.
  
  
  CONCLUSIONS
  Preschool-aged Latino children in farmworker families are sedentary, engaging in little MVPA.
