How Long do Children Play Wii Active Video Games: An Experiment

  1. 1. How Long do Children Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM   Play Wii Active Video Games: An Experiment Tom Baranowski, PhD Professor of Pediatrics (Behavioral Nutrition & PA) USDA/ARS Children’s Nutrition Research Center Baylor College of Medicine Houston, Texas, 77030, USA www.bcm.edu/cnrc/faculty/?PMID=9519 Pediatrics
  2. 2. Substantial interest in Exergames - Active Video Games •  Almost more reviews than there are original articles •  Can they increase PA? •  Do they increase PA at home under naturalistic circumstances? For how long? •  Do they increase PA in unsafe neighborhoods? Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM  
  3. 3. Can they increase PA? (Exercise Physiology) •  The motivated right person under the right circumstances for a sufficient duration can get: -­‐  A moderate work out: •  DDR •  Wii -­‐  A vigorous work out: •  DDR •  Wii Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM  
  4. 4. Do they increase PA at home under naturalistic circumstances? For how long? •  Controversy on this point •  Most studies -­‐  Not experimental -­‐  Did not use objective monitors Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM  
  5. 5. Do they increase PA in unsafe neighborhoods under naturalistic circumstances? (when children are not allowed outside to play) Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM  
  6. 6. Hypotheses •  Children receiving their first active Wii games will have more of an increase in minutes of moderate to vigorous physical activity per day after playing each game and the increase will be cumulative over time (more after one game, and even more after two games) •  During the time playing the games (active games by the active group, inactive games by the inactive group), the group assigned the active games will get more PA during game play than the group playing inactive games •  The effects of these games will be moderated by the perceived safety of neighborhood (unsafe neighborhoods getting more PA) Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM

  9. 9. Sample 2 •  Exclusion Criteria -­‐  Medical problems could prevent playing video games -­‐  Hx of epileptic seizures -­‐  Already have a Wii console -­‐  Not wear accelerometer for 5 of 7 days at baseline -­‐  Live < 12 miles of CNRC Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM  
  10. 10. Measures •  Child accelerometers -­‐  Device that objectively measure PA •  Worn 7 days at each of 5 time intervals •  Child received Wii console if provided all measures Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM

  18. 18. Conclusions •  Children obtaining Wii console and two active Wii video games did not participate in increased PA over those receiving two inactive Wii video games •  Children receiving the active Wii games and living in an unsafe neighborhood did not participate in increased PA over those in safe neighborhoods •  What could be done with active video games to increase the level of PA? And maintain it? Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM  
  19. 19. Strengths of the Study •  Random assignment to condition •  Objective measure of PA for multiple days at 5 time intervals •  High maintenance rage •  High complete data Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM  
  20. 20. Limitations/Weaknesses •  Modest sample •  Only in Houston •  Some cross-game contamination •  (but naturalistic in circumstances) •  Could not link accelerometry data with time of active game play •  Findings do not generalize to other ages •  Findings do not generalize to other AVG systems Pediatrics Games  for  Health  Wednesday,  May  18,  2011   5:30-­‐6:00  PM

  24. 24. The effect of group and time on average minutes per day •  aThere was a significant week effect for sedentary minutes[F=26.31, p<.0001]. The week effect indicates that Week 6 was significantly different from baseline, Week 1, Week 7 and Week 12. Sedentary minutes at Week 6 were higher than at baseline, Week 1, Week 7 and Week 12.
