title: Parent-Adolescent Patterns of Physical Activity, Sedentary Behaviors and Sleep Among a Sample of Overweight and Obese Adolescents.
abstract: BACKGROUND
  The purpose of this study was to examine the association between parent and adolescent levels of physical activity, sedentary behaviors, and sleep among a group of overweight and obese adolescents.
  
  
  METHODS
  Baseline data of parent-adolescent pairs who enrolled in a lifestyle modification intervention were analyzed for this study (n = 176). Participants completed questionnaires about their screen time (TV, video game, and computer time), wore an accelerometer for 8 days, and completed a sleep diary for 1 week. In total, 98 parent-adolescent dyads provided valid data for the analyses. Multivariable regression analyses were conducted to assess the relationship between parent and adolescent's moderate-to-vigorous activity (MVPA), step counts, sedentary behaviors, and sleep duration. Analyses were split by weekday, weekday evening and weekend.
  
  
  RESULTS
  Parent-adolescent MVPA was significantly associated on weekdays (b = 0.18; SE = 0.08; β = 0.26), weekday evenings (b = 0.21; SE = 0.08; β = 0.28), and weekends (b = 0.29; SE = 0.12; β = 0.27). This study found associations between parent-child video game time on weekends (b = 1.10; SE = 0.49; β = 0.24) and computer time on weekdays (b = 0.42; SE = 0.19; β = 0.23). Adolescent sleep was associated with parental sleep on weekdays only (b = 0.38; SE = 0.09; β = 0.46).
  
  
  CONCLUSIONS
  The findings warrant further investigation into the direction and mechanism of the relationship between parent and adolescent weight related behaviors.
