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 effect of adult participation in a school-based family intervention to improve Children's diet and physical activity: the Child and Adolescent Trial for Cardiovascular Health.
UNLABELLED BACKGROUND . There are strong theoretical reasons for including a family component with a school-based intervention aim ed at eating , activity , and smoking behaviors , but the empirical findings to date are limited and show mixed results . The overall CATCH family intervention added only knowledge and attitudinal effects , but no additional behavioral outcomes . This study provides a dose analysis of the family component of the CATCH study by assessing the effect of the level of adult participation . METHOD This secondary analysis included students who attended a CATCH family intervention school during all 3 years of the study . The extent of the adult-child interaction , the key aspect of the CATCH family intervention , was measured by the number of activity packets that an adult household member completed with the child . Multiple regression analysis was used to assess the association of adult participation with the child 's knowledge , attitudes , and behaviors related to diet and physical activity . RESULTS Statistically significant results suggested that dose effects were found for knowledge and attitudes related to diet and physical activity . These effects were more pronounced for minority and male students . CONCLUSIONS These results suggest that dose response of a family intervention has been shown in the acquisition of positive knowledge and attitudes toward health habit changes . The methodology of dose response can be applied to other health promotion projects
