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 .
Impact of the Bienestar school-based diabetes mellitus prevention program on fasting capillary glucose levels: a randomized controlled trial.
OBJECTIVE To evaluate the impact of a school-based diabetes mellitus prevention program on low-income fourth- grade Mexican American children . DESIGN A r and omized controlled trial with 13 intervention and 14 control schools . SETTING Elementary schools in inner-city neighborhoods in San Antonio , Tex . PARTICIPANTS Eighty percent of participants were Mexican American and 94 % were from economically disadvantaged households . Baseline and follow-up measures were collected from 1419 ( 713 intervention and 706 control ) and 1221 ( 619 intervention and 602 control ) fourth- grade children , respectively . INTERVENTION The Bienestar Health Program consists of a health class and physical education curriculum , a family program , a school cafeteria program , and an after-school health club . The objectives are to decrease dietary saturated fat intake , increase dietary fiber intake , and increase physical activity . MAIN OUTCOME MEASURES The primary end point was fasting capillary glucose level , and the secondary end points were percentage of body fat , physical fitness level , dietary fiber intake , and dietary saturated fat intake . Fasting capillary glucose level , bioelectric impedance , modified Harvard step test , three 24-hour dietary recalls , weight , and height were collected at baseline and 8 months later . RESULTS Children in the intervention arm attended an average of 32 Bienestar sessions . Mean fasting capillary glucose levels decreased in intervention schools and increased in control schools after adjusting for covariates ( -2.24 mg/dL [ 0.12 mmol/L ] ; 95 % confidence interval , -6.53 to 2.05 [ -0.36 to 0.11 mmol/L ] ; P = .03 ) . Fitness scores ( P = .04 ) and dietary fiber intake ( P = .009 ) significantly increased in intervention children and decreased in control children . Percentage of body fat ( P = .56 ) and dietary saturated fat intake ( P = .52 ) did not differ significantly between intervention and control children . CONCLUSION This intervention showed some positive results , but additional research is needed to examine long-term benefits , translation , and cost-effectiveness
