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 .
Effects of a classroom-based weight-control intervention on cardiovascular disease in elementary-school obese children.
BACKGROUND Childhood obesity has become a growing public health issue in Taiwan . Obese children have risk factors for type 2 diabetes and cardiovascular disease . In this prospect i ve study , we investigated the effect of a twelve-week heart health education and physical activity program on body weight and risk factors for type 2 diabetes and cardiovascular disease . METHODS Subjects were 120 obese fifth grade rs ( 65 boys and 55 girls , aged 10 - 13 years ( mean 10.6 yrs ) , body mass index ( BMI ) at the 95th percentile or more ) and were r and omly assigned to an intervention group ( n=60 ) or control group ( n=60 ) . The intervention group received a twelve-week heart health education and physical activity program , while the control group did not . In both groups , a series of examinations were done at baseline and post-test , including height , weight , BMI , body fat , blood pressure ( BP ) , physical fitness ( 800-meter running test ) , heart health knowledge , and serum biochemistry . Differences for baseline and post-test data were compared between both groups . RESULTS Mean changes in the intervention group versus control group were significant for weight ( P = 0.024 ) , BMI ( P = 0.047 ) , percentage body fat ( P = 0.008 ) , physical fitness ( 800-meter running test ) ( P = 0.025 ) , heart health knowledge ( P = 0.006 ) , total cholesterol ( P = 0.027 ) , triglycerides ( P = 0.018 ) , high-density lipoprotein cholesterol ( HDL-C ) ( P = 0.009 ) , low-density lipoprotein cholesterol ( LDL-C ) ( P = 0.041 ) , sugar ( P = 0.035 ) , insulin ( P = 0.007 ) , and insulin resistance ( HOMA-IR ) ( P = 0.028 ) . At post-test , weight , BMI , body fat , total cholesterol , triglycerides , LDL-C , sugar , insulin and HOMA-IR had decreased , but HDL-C had increased in the intervention group . CONCLUSIONS A classroom-based weight-control intervention provides educational programs to promote cardiovascular health in children . This intervention is simple , practical , and beneficial for elementary school children
