There was some evidence that school-based physical activity interventions had a positive impact on four of the nine outcome measures .
Specifically positive effects were observed for duration of physical activity , television viewing , VO2 max , and blood cholesterol .
Generally , school-based interventions had little effect on physical activity rates , systolic and diastolic blood pressure , BMI , and pulse rate .
At a minimum , a combination of printed educational material s and changes to the school curriculum that promote physical activity result ed in positive effects .
Few changes in outcomes were observed in this up date with the exception of blood cholesterol and physical activity rates .
For example blood cholesterol was no longer positively impacted upon by school-based physical activity interventions .
The evidence suggests the ongoing implementation of school-based physical activity interventions at this time , given the positive effects on behavior and one physical health status measure .
BACKGROUND The World Health Organization ( WHO ) estimates that 1.9 million deaths worldwide are attributable to physical inactivity and at least 2.6 million deaths are a result of being overweight or obese .
In addition , WHO estimates that physical inactivity causes 10 % to 16 % of cases each of breast cancer , colon , and rectal cancers as well as type 2 diabetes , and 22 % of coronary heart disease and the burden of these and other chronic diseases has rapidly increased in recent decades .
OBJECTIVES The purpose of this systematic review was to summarize the evidence of the effectiveness of school-based interventions in promoting physical activity and fitness in children and adolescents .
The effect of feedback and information on children's pedometer step counts at school.
This study examined whether feedback or feedback plus physical activity information could increase the number of pedometer steps taken during 1 school week . One hundred seventy-seven students ( mean age 9.124 + /- 1.11 years ) in three elementary schools participated . Schools were r and omly assigned to control ( CON ) , feedback ( FB ) , or feedback plus information ( FB+I ) groups . Children wore pedometers during school time for 5 consecutive weekdays . The total steps of the groups were recorded at the end of each school day , with students in the FB and FB+I groups free to view their step counts . In addition , the FB+I group received information and ideas about how they could increase their daily steps . The CON group received no step-count feedback or information . Students in the FB+I group achieved significantly more steps per minute ( 17.17 + /- 4.87 ) than those in the FB ( 13.77 + /- 4.06 , p = 0.003 ) and CON ( 12.41 + /- 3.12 , p = 0.0001 ) groups . Information , as well as step-count feedback , increased elementary students ' school-based physical activity ( number of steps ) in the short term . A longer intervention period is necessary to assess the sustained impact of this type of approach
