Brief Summary:
Randomized controlled trial to test the efficacy of reducing television videotape and video game use to prevent obesity increase physical activity improve physical fitness and decrease dietary fat and calorie intake among third grade children in twelve ethnically-diverse elementary schools
Detailed Description:
The United States has experienced dramatic increases in obesity among both children and adults Population-based primary prevention may hold the greatest promise Unfortunately obesity prevention programs that have specifically attempted to reduce fat and calorie intake and increase physical activity have been relatively ineffective at reducing body fatness As a result there is a pressing need for innovative interventions to prevent obesity
Children spend more time watching television and videotapes and playing video games than in any other activity except sleeping As a result there has been widespread speculation that television viewing might be one of the most easily modifiable causes of obesity among children This hypothesis has broad appeal but has been difficult to validate Epidemiological studies have consistently found weak associations between media use and childhood obesity and additional epidemiological studies are unlikely to help clarify these relationships
We propose an innovative experimental model In the current environment in which television viewing is already so prevalent the question of greatest clinical practical and policy importance is Will reducing television videotape and video game use prevent childhood obesity As a foundation for this proposal we have completed two pilot studies that demonstrate 1 it is possible to significantly reduce childrens television videotape and video game use and 2 that a school-based intervention to reduce childrens television videotape and video game use may result in clinically significant decreases in adiposity
We propose a school-based randomized controlled trial involving 12 ethnically- and socioeconomically-diverse elementary schools and approximately 900 third graders Six schools will be randomly assigned to receive an intervention to reduce television videotape and video game use and the other six schools will receive an attention-placebo control intervention to minimize the potential for compensatory rivalry or resentful demoralization Our proposed intervention model is derived directly from principles of Banduras social cognitive theory and includes a classroom curriculum and parent newsletters The primary intervention will be delivered throughout the third grade school year
Survey and physical assessments of all children will occur at baseline at the end of 3rd grade post-test and at the beginning and end of 4th grade 4 month and one year follow-ups respectively A subsample of children will participate in 4 days of activity monitoring and three 24-hour dietary recalls at baseline post-test and one-year follow-up Parents will be interviewed by phone
PRIMARY HYPOTHESIS Compared to controls third grade children exposed to a school-based intervention to reduce time spent watching television and videotapes and playing video games will significantly reduce their body mass index BMI kgm2 In addition triceps skinfold thickness and waist and hip ratio will be measured to further characterize changes in obesity resulting from the intervention
SECONDARY HYPOTHESES Children attending intervention schools will significantly decrease the amount of time they spend watching television watching videotapes and playing video games Children attending intervention schools will significantly increase their levels of moderate to vigorous physical activity and total physical activity Children attending intervention schools will significantly improve their physical fitness Children attending intervention schools will significantly reduce their fat intakes and total calorie intakes Children attending intervention schools will significantly reduce the number of meals and snacks they eat while watching television and videotapes or playing video games
