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 .
Physical activity, bodyweight, health and fear of negative evaluation in primary school children.
Fear of negative evaluation ( FNE ) is regarded as being the core feature of social anxiety . The present study examined how FNE is associated with  physical activity ( PA ) , body mass index ( BMI ) and perceived physical health ( PPH )  in children . Data were collected in a sample of 502 primary school children in first and fifth grade s taking part in a r and omized-controlled trial ( " Kinder-Sportstudie KISS " ) aim ed at increasing PA and health . PA was assessed by accelerometry over 7 days , PPH by the Child Health Question naire and FNE by the  Social Anxiety Scale for Children -- Revised . BMI z-scores were calculated based on Swiss norms . Cross-sectional analyses indicated that children high in FNE exercised less , reported lower levels of PPH and had higher BMI z-scores ( P<0.01 ) . Using mixed linear models , the school-based PA intervention did not manage to reduce FNE scores . Overweight children demonstrated a greater increase in FNE ( P<0.05 ) indicating that enhanced weight may be a risk factor for FNE . In conclusion , the associations among high FNE , low PA and increased BMI should be considered when promoting an active lifestyle in children
