Study population: Children and adolescents aged 6 to 18 years of age included in the school environment, regardless of their ethnicity, social condition and weight range.

Brief summary: The aim of this study focuses on obtaining accurate information on the effectiveness of interventions involving physical activity and/or nutrition education developed in the school environment. This study is intended to assist in future assembly and development of effective school practices related to preventing and reducing levels of overweight in children and adolescents.

Detailed description: The inordinate increase in the prevalence of overweight and obesity at the international level today is one of the targets of concern the department of public health, and gradually has been the focus of many studies and interventions which emphasize the need for more evidence to clear and effective its prevention and reduction. Obesity can affect the short or long term health of individuals, through problems such as left ventricular hypertrophy in young-adult and atherosclerosis, which is due to the formation of plaques of fat in the arterial wall and may lead to coronary artery disease , cerebrovascular disease and peripheral vascular disease.

The promotion of regular practice of physical activity through physical education school can be an effective way to prevent obesity among children, especially girls. There is an inverse relationship between physical activity and incidence of hypertension. The earlier the entrance to the practice of physical activities, there will be more effective in combating the increase in body mass index (BMI).

Nutrition Education is to extend the knowledge on nutrition and the ability to understand the practices and eating behavior, improving the relationship of the individual in the environment which is introduced, allowing the taking of decisions under the situation presented.

Eligibility criteria: Inclusion Criteria:

* Randomized clinical / community trials whose main objective is the focus on control and / or reduction of body weight of the participants, conducted by a program developed in the scholar environment that promotes the practice of physical activity and healthy eating through nutrition education.
* Studies that include participants aged 6 to 18 years of age, regardless of the range of weight.
* There is no restriction ethnic, social, gender, nutritional status and physical fitness.
* There is no limitation of language for critical evaluation of studies.

Exclusion Criteria:

* Studies making use of pharmacological agents
* Studies with participants who suffer from diseases, or specific clinical conditions, except obesity
* Studies not conducted in the school environment
* The duplicated data will be excluded.

Primary outcomes:
measure: Body Mass Index (BMI)
timeFrame: Assessments results should at least monitor the execution time of the intervention studies, with a minimum of two assessments: pre-and post-intervention. This requirement depends directly on the studies to be extracted in the systematic search.
Secondary outcomes:
measure: Body Weight
timeFrame: requirement for pre and post-intervention assessments
measure: Blood Pressure
timeFrame: requirement for pre and post-intervention assessments
