title: Factors associated with communication-based sedentary behaviors among youth: are talking on the phone, texting, and instant messaging new sedentary behaviors to be concerned about?
abstract: OBJECTIVE
  Sedentary behavior research typically only examines screen time activities and not communication time activities, such as talking on the phone, texting, or instant messaging.
  
  
  METHODS
  Data from 2,449 grade 5 to 8 students were used to examine factors associated with the time youth spent in communication-based sedentary behaviors.
  
  
  RESULTS
  Screen time, physical activity, grade, and gender were associated with moderate and high communication time.
  
  
  CONCLUSIONS
  Future research on sedentary behavior should include measures of communication time.
