Systematic Review Up to Nov. 2007 Primary and Secondary Schools 18 Studies USA-Europe |
Policy assessed More efficacy in: - Implementation of recommendations and price interventions - Regulation of access to foods and beverages |
Some policies have been effective in improving food environment and dietary intake Little evaluation of impact on IMC |
More long term studies are necessary |
|
2009- Effectiveness of school nutrition policies. |
Khambalia, A |
Systematic Review 1990-2010 8 studies:, 3 meta-analysis and 5 systematic reviews All in English |
School-based Reviews that considered individual studies which examined behavioural interventions for preventing or controlling overweight or obesity (PA, diet or both). |
The meta-analyses concluded that school-based obesity interventions had a significant, albeit modest, effect in achieving weight reduction in school settings |
Little evidence. More high quality Studies are needed |

2012- Effectiveness of School based obesity interventions |
Lobelo, F |
Systematic review 1965-2010 10 studies Latin America |
School-based Evaluated an obesity related outcome (body mass index [BMI], weight, %body fat, waist circumference, BMI z -score), - Comparative (exposed vs not exposed) |
Most successful interventions were focused on: Prevention Longer follow-ups Multidisciplinary team, Fewer limitations in execution 5/10 Positive outcomes |
Sufficient evidence to recommend school-based interventions to prevent obesity among youth in Latin America. |

Lavelle, H |
Systematic review & meta-analysis 1991-2010 43 studies Population =<18 y. Europe-US-Brazil |
Stratified analysis 26% studies PA only 7% education alone 69% combined PA interventions with nutrition |
PA alone and or PA plus nutrition, was associated with significant improvements in BMI |
School-based interventions that contain a physical activity component may be to reduce BMI |
|
2012- Effectiveness of school-based interventions to reduce BMI |
Metcalf |
Systematic review & Meta-analysis 2003-2011 30 Studies 16 years or younger |
Randomized controlled trials or controlled clinical trials Studies designed to increase the physical activity of children/adolescents. At least four week. |
Physical activity Interventions do not affect the overall activity levels of children |
Strong evidence that physical activity interventions have had only a small effect (approximately 4 minutes more walking or running per day) on children's overall activity levels |
|
2012-2013 Effectiveness of intervention on physical activity of children |
Brown, T |
Systematic Review 38 RCT 13 from NICE 7 NE and PA |
School-based Only includes studies that reported a weight outcome. Studies with a lifestyle intervention (diet, PA, diet plus PA) |
Physical activity interventions may help children maintain a healthy weight The results are inconsistent and short-term. Physical activity interventions may be more successful in younger children and in girls. |
Use qualititave and quantitative outcomes Combination of both PA and diet intervention tend to be more effective |
|
2009 Interventions that focus on changing dietary intake and physical activity levels to prevent childhood obesity |
Waters, E
|
Review & Meta-analysis Case-Control Studies (Randomized or not) At least 12 weeks 55 Studies (37 meta-analysis) 6-12 years old |
Studies were included if they evaluated interventions, policies or programs in place for twelve weeks or more |
Programs were effective at reducing adiposity, although not all individual interventions were effective |
Strong evidence to support beneficial effects of child obesity prevention programs on BMI, Include recommendations and strategies |

2011 Cochrane Review |
Guerra, PH
|
Meta-analysis Published after 2000 33 articles 6-18 years old |
School based RCT on PA and NE Performed PA and NE interventions for children and adolescents Described the BMI outcome in both intervention and control groups |
Showed no statistically significant mean reduction on children's and adolescents' BMI in normal population. Little positive effect was observed when including OW and OB |
More studies are needed in order to provide an effective framework to be implemented in the school setting. |
