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 Nutrition and Enjoyable Activity for Teen Girls (NEAT girls) randomized controlled trial for adolescent girls from disadvantaged secondary schools: rationale, study protocol, and baseline results
Background Child and adolescent obesity predisposes individuals to an increased risk of morbidity and mortality from a range of lifestyle diseases . Although there is some evidence to suggest that rates of pediatric obesity have leveled off in recent years , this has not been the case among youth from low socioeconomic background s. The purpose of this paper is to report the rationale , study design and baseline findings of a school-based obesity prevention program for low-active adolescent girls from disadvantaged secondary schools . Methods / Design The Nutrition and Enjoyable Activity for Teen Girls ( NEAT Girls ) intervention will be evaluated using a group r and omized controlled trial . NEAT Girls is a 12-month multi-component school-based intervention developed in reference to Social Cognitive Theory and includes enhanced school sport sessions , interactive seminars , nutrition workshops , lunch-time physical activity ( PA ) sessions , PA and nutrition h and books , parent newsletters , pedometers for self-monitoring and text messaging for social support . The following variables were assessed at baseline and will be completed again at 12- and 24-months : adiposity , objective ly measured PA , muscular fitness , time spent in sedentary behaviors , dietary intake , PA and nutrition social-cognitive mediators , physical self-perception and global self-esteem . Statistical analyses will follow intention-to-treat principles and hypothesized mediators of PA and nutrition behavior change will be explored . Discussion NEAT Girls is an innovative intervention targeting low-active girls using evidence -based behavior change strategies and nutrition and PA messages and has the potential to prevent unhealthy weight gain and reduce the decline in physical activity and poor dietary habits associated with low socio-economic status . Few studies have reported the long-term effects of school-based obesity prevention programs and the current study has the potential to make an important contribution to the field .
