BackgroundDespite the well-established health benefits of physical activity (PA) for young people (aged 4–19 years), most do not meet PA guidelines. Policies that support PA in schools may be promising, but their impact on PA behavior is poorly understood. The aim of this systematic review was to ascertain the level and type of evidence reported in the international scientific literature for policies within the school setting that contribute directly or indirectly to increasing PA.MethodsThis systematic review is compliant with Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Six databases were searched using key concepts of policy, school, evaluation, and PA. Following title and abstract screening of 2323 studies, 25 progressed to data synthesis. Methodological quality was assessed using standardized tools, and the strength of the evidence of policy impact was described based on pre-determined codes: positive, negative, inconclusive, or untested statistically.ResultsEvidence emerged for 9 policy areas that had a direct or indirect effect on PA within the school setting. These were whole school PA policy, physical education, sport/extracurricular PA, classroom-based PA, active breaks/recess, physical environment, shared use agreements, active school transport, and surveillance. The bulk of the evidence was significantly positive (54%), 27% was inconclusive, 9% was significantly negative, and 11% was untested (due to rounding, some numbers add to 99% or 101%). Frequency of evidence was highest in the primary setting (41%), 34% in the secondary setting, and 24% in primary/secondary combined school settings. By policy area, frequency of evidence was highest for sport/extracurricular PA (35%), 17% for physical education, and 12% for whole school PA policy, with evidence for shared use agreements between schools and local communities rarely reported (2%). Comparing relative strength of evidence, the evidence for shared use agreements, though sparse, was 100% positive, while 60% of the evidence for whole school PA policy, 59% of the evidence for sport/extracurricular PA, 57% of the evidence for physical education, 50% of the evidence for PA in classroom, and 50% of the evidence for active breaks/recess were positive.ConclusionThe current evidence base supports the effectiveness of PA policy actions within the school setting but cautions against a “one-size-fits-all” approach and emphasizes the need to examine policy implementation to maximize translation into practice. Greater clarity regarding terminology, measurement, and methods for evaluation of policy interventions is needed.  相似文献

Montem, a triennial customary march by Eton scholars, consolidated into a public expression of patrician social identity under the patronage of the monarchy in the late eighteenth century. This analysis of Montem’s history traces its development from a boy-led pageant of misrule to a public performance of elite patriotism. The custom, which attracted national attention, sheds new light on boy governance and self-fashioning in the period’s elite schools. This article argues that a study of Montem disrupts the standard historiographical narrative of anarchy and violence in the great schools and suggests that boy culture was more complex than previously acknowledged.  相似文献

Background:Farmworker-serving community health workers have limited access to farmworker health research findings, training, and education resources. With funding from the National Library of Medicine, we are working to improve the health information literacy of both community health workers and farmworkers. We conducted focus group discussions with community health workers to explore their experiences providing health education and information to farmworkers, their information-seeking behaviors, and their technology and information needs. Data from the focus groups provided insights into the main areas in which community health workers would like to receive professional development.Case Presentation:Our team, which includes health sciences librarians, developed a resource list of educational materials for farmworker health, videos to increase community health workers'' skills finding health information online, and webinars to introduce these resources to community health workers. Videos, available in Spanish and English, included instruction on finding and evaluating online health information, accessing reputable online consumer health information sources, and advanced searching tips for Google and PubMed. Through three webinars, we introduced the resource list, videos, and design software for creating handouts and infographics to community health workers.Conclusions:Community health workers have a critical role in providing health education and information to farmworkers, and our efforts represent a first step in addressing community health workers'' limited access to professional development. Health sciences librarians are well positioned to partner with interdisciplinary teams working to reduce health disparities and provide resources and training to community health workers, farmworkers, and other underserved communities.  相似文献

The socialist People’s Democratic Republic of Laos (Lao PDR) has some of the largest intact forests in Southeast Asia, yet these are being quickly depleted by illegal logging, slash-and-burn farming, increasing population pressures, monocrop plantations, mining and dam building. Foreign government and nongovernmental organizations stage “infotainment” theatre plays to educate and inform the Lao public of its role in protecting the forests even though government projects and concessions are the primary causes of forest destruction. Because all the nationally subsidized performing arts troupes are government mouthpieces they cannot critique the government’s role. Foreign aid agencies funding the dramas are also made complicit in the hypocrisy of promoting forest protection to those with the least power to do so, while both performers and spectators know who is profiting the most from the sale of forest products. This article examines theatrical performances regarding forest protection presented in this context of performativity in which the state manipulates socialist rhetoric to conceal its actions that enrich its officials and capitalist partners at the expense of the rest of the Lao public.  相似文献
