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 .
Quality of life in Mexican-American children following a weight management program.
OBJECTIVE The objective was to evaluate quality of life ( QOL ) in at-risk-for-overweight and overweight Mexican-American children after participating in 6 months of intensive weight management or self-help . RESEARCH METHODS AND PROCEDURES Eighty sixth- and seventh- grade at-risk-for-overweight ( BMI > or=85th to < 95th percentile ) and overweight ( BMI > or=95th percentile ) Mexican-American children were r and omly assigned to either intensive instructor-led intervention ( ILI ) or self-help ( SH ) . The ILI condition included daily participation for 12 weeks in a school-based program comprised of nutrition education , physical activity , and behavior modification , followed by ongoing monthly maintenance .  QOL was assessed at baseline and 6 months via child self-report PedsQL . QOL outcomes were compared across treatment groups , and the impact of change in z BMI on change in QOL was evaluated . RESULTS Children in the ILI condition not only achieved significantly greater weight loss ( z BMI , -0.13 + /- 0.14 ; p < 0.001 ) but also significantly greater physical QOL improvements than those in the SH condition at 6 months ( p < 0.05 ) . Furthermore , physical QOL increases were associated with z BMI reduction ( p < 0.05 ) . However , neither psychosocial nor total QOL was significantly impacted by intervention or z BMI change . DISCUSSION These findings show that even modest decreases in z BMI after weight management result in improved physical QOL in Mexican-American children . These results illustrate the clear need to include evaluation of QOL in the process of identifying effective weight management programs
