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 Fun, Food, and Fitness Project (FFFP): the Baylor GEMS pilot study.
OBJECTIVE The Girls health Enrichment Multisite Studies ( GEMS ) Fun , Food , and Fitness Project ( FFFP ) was design ed to prevent obesity among 8-year-old African-American girls . DESIGN Twelve-week , two-arm parallel group r and omized controlled pilot study . SETTING Summer day camp and homes in Houston , Texas . PARTICIPANTS Thirty-five girls and their parents or caregivers were r and omly assigned to treatment ( N=19 ) or control groups ( N=16 ) . INTERVENTION Girls in the intervention group attended a special 4-week summer day camp , followed by a special 8-week home Internet intervention for the girls and their parents . Control group girls attended a different 4-week summer day camp , followed by a monthly home Internet intervention , neither of which components included the GEMS-FFFP enhancements . MAIN OUTCOME MEASURES Body mass index ( BMI ) , consumption of fruit , 100 % fruit juice , and vegetables ( FJV ) , physical activity . RESULTS After adjusting for baseline BMI , there were no significant differences in BMI between treatment and control group girls , either at the end of the 4-week summer day camp , or after the full 12-week intervention . By the end of the summer camp , the subgroup of treatment group girls heavier at baseline exhibited a trend ( P<.08 ) toward lower BMI , compared to their heavier counterparts in the control group . Overall results at the end of the 12-week program demonstrated substantial , although not significant , differences between treatment and control groups in the hypothesized directions . On average , less than half the treatment sample logged onto the Website , which limited intervention dose . CONCLUSIONS Summer day camp appears to offer promise for initiating health behavior change . Effective methods must be developed and tested to enhance log-on rates among healthy children and their parents before Internet programs can achieve their potential
