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 .
Obesity prevention in low socioeconomic status urban African-American adolescents: study design and preliminary findings of the HEALTH-KIDS Study
Objectives : Obesity prevention among children and adolescents is a public health priority ; however , limited school-based intervention trials targeting obesity have been conducted . This article provides an overview of the study design and baseline preliminary findings of our ongoing school-based intervention study . Design : R and omized intervention trial to test a school-based , environmental obesity prevention program in urban low socioeconomic status ( SES ) African-American adolescents . The intervention program was developed based on several behavioral theories and was guided by preliminary findings based on focus group discussion and baseline data . Setting : Four Chicago public schools in the US.Subjects : Over 450 5–7th grade rs and their families and schools were involved . Results : Our baseline data indicate a high prevalence of overweight ( 43 % in boys and 41 % in girls ) and a number of problems in these children 's physical activity and eating patterns . Only 26 % reported spending ⩾20 min engaged in vigorous-moderate exercise  in ⩾5 days over the past 7 days ; 29 % reported spending ⩾5 h each day watching TV , playing video games , or using computer . They also consumed too many fried foods and soft drinks . On average , 55 % consumed fried foods ⩾2 times/day over the past 7 days ; regarding soft drinks , 70 % reported consuming ⩾2 times/day . Conclusion : School-based obesity prevention programs are urgently needed in the target US urban , low SES , minority communities . These data can be used to inform intervention activities
