QUESTION: Can a school based intervention aimed at reducing television and videotape viewing and use of video games decrease adiposity in children in grades 3 and 4 (approximate age 9 y)?
7 month, randomised (allocation concealed*), blinded (outcome assessors and statisticians*), controlled trial.
2 public elementary schools in a single school district in San Jose, California, USA.
198 of 227 eligible children in grades 3 and 4 had parental consent to participate. 192 children (97%) (mean age 9 y) completed both the baseline and post-intervention assessments.
The 2 schools were matched on sociodemographic and scholastic variables. One school (106 eligible children) was allocated to implement an intervention to reduce television use by limiting access to television sets, budgeting watching or playing time, and more selective use. 18 lessons of 30-50 minutes each were incorporated into the standard curriculum and taught by regular classroom teachers who received special training. The second school (n=121 eligible children) received the usual curriculum (control group).
Main outcome was adiposity (body mass index [BMI]) measured at baseline (September 1996) and after the intervention (April 1997).
