Impact of Non-Commercialism Policy in Seattle Schools

描述(由申请人提供)： 这项关于西雅图学校非商业主义政策影响的试点研究将评估和评估西雅图学校董事会最近投票通过的一项现实生活中的政策决定与肥胖相关的健康结果。这项政策是应家长和公民团体几年来的倡导而制定的，旨在通过减少学生暴露在广告和其他营销压力下，减少西雅图公立学校的商业性，包括来自商业食品供应商的压力。政策实施的时间表和细节由学校校长决定。为了这项试点研究的目的，西雅图学区同意在一所高中加快该政策的实施(干预)，并在另一所高中推迟一年(对照)。这两所学校在规模和学生特征上是匹配的，少数民族入学率达到90%。在第一年，干预高中将获得资金和人员配备，以促进与加快采用学区政策相关的环境变化。控制学校将在第二年获得相同的资金和人员配备。我们的主要研究假设是，将学校环境从商业压力中解放出来，将影响学生对营养和体育活动的态度、意图和行为。由疾病预防控制中心开发的学校健康指数将是衡量两所学校在基线和干预后的环境的主要指标。对学生态度和行为的调查问题将基于西雅图学校实施的青少年健康调查。出于隐私和保密的原因，西雅图学校的学生不会定期称重，也无法获得测量的BMI数据。学生在基线和研究结束时的体重将在校本健康中心的合作下获得。这项研究还将记录每所学校的政策制定和执行过程。学区感兴趣的是开发监测工具，这些工具可用作改善学校环境和确定变革障碍的进展指标。研究结果将使西雅图公立学校能够评估决策决策对健康的影响，为更大规模的随机对照试验做准备。这一合作试点代表了一种完全不同的学校卫生干预方法，其中许多从未被学区或个别学校作为可持续的政策采用。帮助实施和评估现实生活中的政策对可持续性和在研究人员、公共卫生机构和公立学校之间建立联盟具有更大的希望。

DESCRIPTION (provided by applicant): This pilot study on the Impact of a Non-commercialism Policy in Seattle Schools will assess and evaluate obesity-related health outcomes of a real-life policy decision, recently voted on and adopted by the Seattle School Board. The policy, developed in response to several years' advocacy by parents and citizen groups, is intended to decrease commercialism in Seattle Public Schools by reducing the students' exposure to advertising and other marketing pressures, including those from commercial food vendors. The timetable and details of policy implementation are left to school principals. For purposes of this pilot study, the Seattle School District has agreed to accelerate the implementation of the policy in one high-school (intervention) and to delay it by a year in another (control). The two schools are matched for size and student characteristics and have 90% minority enrollment. In the first year, the intervention high school will receive funds and staffing to promote an environmental change related to an accelerated adoption of the District policy. The same funds and staffing will be available during the second year to the control school. Our primary research hypothesis is that freeing the school environment from commercial pressures will affect the students' attitudes, intentions, and behaviors related to nutrition and physical activity. The School Health Index, developed by the CDC, will be the main measure of the two schools' environment at baseline and following the intervention. Survey questions of students' attitudes and behaviors will be based on the Teen Health Survey that is administered in Seattle schools. For reasons of privacy and confidentiality, students in Seattle schools are not routinely weighed, and measured BMI data are not available. The students' weights at baseline and at the end of the study will be obtained with the cooperation of the school-based health centers. The study will also document the process of policy development and implementation at each school. The School District is interested in developing monitoring tools that can be used as indicators of progress toward improving the school environment and in identifying barriers to change. Study results will allow Seattle Public Schools to evaluate the health impact of policymaking decisions, preparatory to a larger randomized controlled trial. This collaborative pilot represents a radically different approach to school-based health interventions, many of which are never adopted as a sustainable policy by the district or by individual schools. Helping to implement and evaluate a real-life policy holds greater promise for sustainability and for building coalitions between researchers, public health agencies and public schools .
