ABSTRACT Recommendations for physical activity in the Guide to Community Preventive Services (the Community Guide) have not been systematically examined or applied in developing countries such as those in Latin America. The aim of this systematic review was to assess the current evidence base concerning interventions to increase physical activity in Latin America using a modified Community Guide process and to develop evidence-based recommendations for physical activity interventions.
In 2006, a literature review of both peer-reviewed and non-peer-reviewed literature in Portuguese, Spanish, and English was carried out to identify physical activity interventions conducted in community settings in Latin America. Intervention studies were identified by searching ten databases using 16 search terms related to physical activity, fitness, health promotion, and community interventions. All intervention studies related to physical activity were summarized into tables. Six reviewers independently classified the intervention studies by the categories used in the Community Guide and screened the studies for inclusion in a systematic abstraction process to assess the strength of the evidence. Five trained researchers conducted the abstractions.
The literature search identified 903 peer-reviewed articles and 142 Brazilian theses related to physical activity, of which 19 were selected for full abstraction. Only for school-based physical education classes was the strength of the evidence from Latin America sufficient to support a practice recommendation.
This systematic review highlights the need for rigorous evaluation of promising interventions to increase physical activity in Latin America. Implementation and maintenance of school physical education programs and policies should be strongly encouraged to promote the health of Latin American children.

    ABSTRACT: The global health burden due to physical inactivity is enormous and growing. There is a need to consider new ways of generating evidence and to identify the role of government in promoting physical activity at the population level. In this paper, we summarize key findings from a large-scale cross-national collaboration to understand physical activity promotion in Brazil. We describe the main aspects of the partnership of Project GUIA (Guide for Useful Interventions for Activity in Brazil and Latin America) that sustained the collaborative effort for eight years and describe how the evidence gathered from the collaboration triggered political action in Brazil to scale up a physical activity intervention at the national level. Project GUIA is a cross-national multidisciplinary research partnership designed to understand and evaluate current efforts for physical activity promotion at the community level in Latin America. This example of scaling up is unprecedented for promoting health in the region and is an example that must be followed and evaluated.

    ABSTRACT: Investigators developed a review system to evaluate the growing literature on policy and environmental strategies to prevent childhood obesity. More than 2000 documents published between January 2000 and May 2009 in the scientific and grey literature were identified (2008-2009) and systematically analyzed (2009-2012). These focused on policy or environmental strategies to reduce obesity/overweight, increase physical activity, and/or improve nutrition/diet among youth (aged 3-18 years). Guided by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework, investigators abstracted studies of 24 intervention strategies and assessed evidence for their effectiveness (i.e., study design, intervention duration, and outcomes) and population impact (i.e., effectiveness and reach-participation or exposure, and representativeness) in 142 evaluation study groupings and 254 associational study groupings (n=396 groupings of 600 peer-reviewed studies). The 24 strategies yielded 25 classifications (school wellness policies yielded nutrition and physical activity classifications): 1st-tier effective (n=5); 2nd-tier effective (n=6); "promising" (n=5); or "emerging" (n=9). Evidence for intervention effectiveness was reported in 56% of the evaluation, and 77% of the associational, study groupings. Among the evaluation study groupings, only 49% reported sufficient data for population impact ratings, and only 22% qualified for a rating of high population impact. Effectiveness and impact ratings were summarized in graphic evidence maps, displaying effects/associations with behavioral and obesity/overweight outcomes. This paper describes the results and products of the review, with recommendations for policy research and practice.

    ABSTRACT: O objetivo deste estudo transversal foi analisar a associação entre a participação nas aulas de Educação Física (EF) e indicadores de violência em estudantes. Um questionário foi usado para coletar dados pessoais, da participação nas aulas de EF e de indicadores de violência em 4.210 adolescentes (14-19 anos) estudantes do ensino médio do estado de Pernambuco, Brasil. A prevalência de “envolvimento em brigas” e de “envolvimento em episódios de violência física como vitima” foi, respectivamente, de 21,2% e 10,7%. Verificou-se que 64,9% dos estudantes relataram não participar das aulas de EF. A prevalência dos indicadores de violência foi maior entre os rapazes, enquanto a não participação nas aulas de EF foi maior entre as moças. Independentemente do sexo e de outras covariáveis, verificou-se que a participação nas aulas de EF foi um fator diretamente associado a envolvimento em brigas. Concluiu-se que a participação nas aulas de EF está associada a envolvimento em brigas em estudantes adolescentes, contrariando, neste caso específico, a hipótese de que a participação nessas aulas está associada a condutas de saúde.
