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 .
Preventing childhood obesity: two year follow-up results from the Christchurch obesity prevention programme in schools (CHOPPS)
Objective To assess the long term effects of an obesity prevention programme in schools . Design Longitudinal results after a cluster r and omised controlled trial . Setting Schools in southwest Engl and . Participants Of the original sample of 644 children aged 7 - 11 , 511 children were tracked and measurements were obtained from 434 children three years after baseline . Intervention The intervention was conducted over one school year , with four sessions of focused education promoting a healthy diet and discouraging the consumption of carbonated drinks . Main outcome measures Anthropometric measures of height , weight , and waist circumference . Body mass index ( BMI ) converted to z scores ( SD scores ) and to centile values with growth reference curves . Waist circumference was also converted to z scores ( SD scores ) . Results At three years after baseline the age and sex specific BMI z scores ( SD scores ) had increased in the control group by 0.10 ( SD 0.53 ) but decreased in the intervention group by −0.01 ( SD 0.58 ) , with a mean difference of 0.10 ( 95 % confidence interval −0.00 to 0.21 , P=0.06 ) . The prevalence of overweight increased in both the intervention and control group at three years and the significant difference between the groups seen at 12 months was no longer evident . The BMI increased in the control group by 2.14 ( SD 1.64 ) and the intervention group by 1.88 ( SD 1.71 ) , with mean difference of 0.26 ( −0.07 to 0.58 , P= 0.12 ) . The waist circumference increased in both groups after three years with a mean difference of 0.09 ( −0.06 to 0.26 , P=0.25 ) . Conclusions These longitudinal results show that after a simple year long intervention the difference in prevalence of overweight in children seen at 12 months was not sustained at three years
