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 effects of a school-based intervention programme on dietary intakes and physical activity among primary-school children in Trinidad and Tobago.
OBJECTIVE Childhood obesity is increasingly being recognized as a major public health problem in the Caribbean . The objective of the present study was to evaluate the effectiveness of a short-term , school-based , multi-component education intervention on improving the knowledge , attitudes and behaviour of primary -school children towards better dietary and activity habits . DESIGN The study was a r and omized , controlled , school-based nutrition education and physical activity intervention . Participating schools were r and omly assigned to the intervention ( IVG ) and non-intervention ( NIVG ) groups . SETTING All primary schools in Sangre Gr and e , north-east Trinidad . SUBJECTS Five hundred and seventy-nine pupils in their sixth year of primary -school education were enrolled from twelve schools in Sangre Gr and e , north-east Trinidad . RESULTS Approximately 23 % of participants had BMI > or= 85th percentile of the Centers for Disease Control and Prevention age- and gender-specific cut-off values . In multivariate regression equations controlling for age , gender , BMI and baseline value , intervention was associated with lower intake levels of fried foods , snack foods high in fat , sugar and salt ( HFSS ) and sodas ( P < 0.05 ) . In similar analyses , intervention was associated with higher knowledge scores ( P < 0.01 ) . Intervention was not significantly associated with physical activity and Children 's Eating Attitude Test-26 ( ChEAT26 ) scores after controlling for age , gender , BMI and the relevant baseline values . CONCLUSIONS The intervention was associated with lower intake levels of fried foods , HFSS foods , sodas and higher knowledge scores independent of age , gender , BMI , ethnicity and the appropriate baseline value . Finally , the intervention was not associated with changes in physical activity behaviours in multivariate analyses
