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 .
Promoting healthy lifestyles among adolescent boys: the Fitness Improvement and Lifestyle Awareness Program RCT.
OBJECTIVE To assess the feasibility , acceptability , and potential efficacy of a school-based obesity prevention program among adolescent boys with sub-optimal cardiorespiratory fitness . METHODS In 2007 , a 6-month , 2-arm parallel group , r and omized controlled pilot trial was conducted in a single school setting ( Sydney , Australia ) . Thirty-three 7th Grade boys ( mean age=12.5+/-0.4 years ) were r and omly assigned to intervention ( n=16 ) or active comparison group ( n=17 ) . The intervention consisted of one 60-minute curriculum session and two 20-minute lunchtime physical activity sessions per week . The active comparison group continued with their usual physical activity curriculum sessions ( Friday afternoons 2 - 3 pm ) . The pilot trial 's curriculum sessions were additional to Physical Education ( PE ) lessons . The primary outcome was BMI , and secondary outcomes included waist circumference , percentage body fat , cardiorespiratory fitness , objective ly measured physical activity and small screen recreation time . RESULTS Screening , recruitment and retention goals were exceeded . The majority of data were collected as planned . Implementation and attendance rates were acceptable . At follow-up , compared with boys in the active comparison group , boys in the intervention group displayed a smaller increase in BMI ( adjust diff.=-0.2 , 95 % confidence interval [ CI ] -0.78 , 0.39 ; Cohen 's d=0.05 ) ; greater reductions in waist circumference ( -1.65 cm [ -4.67 , 1.36 ] ; d=0.15 ) ; percentage body fat ( -1.69 % [ -4.98 , 1.60 ] ; d=0.22 ) and time spent in small screen recreation on weekends ( -1.13 h [ -5.06 , 2.80 ] ; d=0.19 ) ; and a greater increase in cardiorespiratory fitness ( 2.13 laps [ 6.22 , 10.48 ] ; d=0.16 ) ; and participation in total weekday physical activity ( 140.74 counts/min [ -159.44 , 440.92 ] ; d=0.36 ) . CONCLUSIONS This study verified the feasibility , acceptability and potential efficacy of a multifaceted school-based intervention to prevent unhealthy weight gain among adolescent boys
