DESCRIPTION (provided by applicant): The development of school-based obesity screening has been recommended by many public health groups but little is known about the effectiveness of this policy-based obesity prevention strategy. The proposed research will utilize a naturalistic, longitudinal design to study the effectiveness of different BMI screening practices and different feedback/education approaches on preventing obesity among elementary age children. The project capitalizes on an existing infrastructure for BMI tracking and obesity prevention within the state of Pennsylvania. Pennsylvania is one of four states that provide BMI screening results to parents of all K-12 students annually. The Pennsylvania Advocates for Nutrition and Activity (PANA), administered by Pennsylvania State University (PSU) has partnered with the Pennsylvania Department of Health (PDH) to coordinate training, parent communication and education efforts. This infrastructure will make it possible to evaluate the effectiveness of different BMI screening approaches as well as to evaluate the additive benefits of supplemental behaviorally-based screening and family-based education for the prevention of overweight and obesity. The goal of Aim 1 is to evaluate the impact of different BMI reporting practices on school-level BMI outcomes. Longitudinal (3 year) trends in BMI will be related to the type of BMI reporting to determine the relative effectiveness of different approaches. The goal of Aim 2 is to evaluate the potential of employing a validated, behaviorally-based screening tool (Family Nutrition and Physical Activity Screening Tool) in conjunction with standard BMI reports to promote awareness and changes in home environments. Schools will be randomized to receive the standard or supplemental report and effects will be evaluated with surveys and BMI trends. The goal of Aim 3 is to evaluate the effectiveness of an Extension-based family education program (Family Fitness) when implemented as an extension of normal BMI screening programming. The proposed initiative takes advantage of the natural experiment taking place within the state of Pennsylvania to answer important questions about how to enhance the effectiveness of BMI screening, a widely recommended public health strategy. The long-term goal is to develop an evidence-base to facilitate the adoption of primary prevention strategies to reduce risks for overweight and obesity before body changes and behaviors have become entrenched. PUBLIC HEALTH RELEVANCE: The proposed study will evaluate BMI trajectories from an ongoing school-based BMI screening initiative in the state of Pennsylvania to determine best practices for use in coordinated obesity prevention programming. Outcomes from standard BMI report cards will be compared to outcomes from the supplemental use of a behaviorally-based screening tool and an extension- based parent education program to evaluate strategies to establish home environments and practices that can help prevent children from becoming overweight. The study will provide key insights about how to enhance the effectiveness of school-based BMI screening programs, a widely recommended public health strategy.

描述（由申请人提供）：许多公共卫生小组推荐了基于学校的肥胖症筛查的开发，但对这种基于政策的肥胖预防策略的有效性知之甚少。拟议的研究将利用自然主义的纵向设计来研究不同BMI筛查实践的有效性，以及针对预防基本年龄儿童肥胖的不同反馈/教育方法。 The project capitalizes on an existing infrastructure for BMI tracking and obesity prevention within the state of Pennsylvania. Pennsylvania is one of four states that provide BMI screening results to parents of all K-12 students annually.宾夕法尼亚州立大学（PSU）管理的宾夕法尼亚州营养与活动倡导者（PANA）已与宾夕法尼亚州卫生部（PDH）合作，协调培训，家长交流和教育工作。这种基础设施将使您可以评估不同BMI筛选方法的有效性，并评估基于行为基于行为的筛查和基于家庭的教育的累加益处，以防止超重和肥胖。 The goal of Aim 1 is to evaluate the impact of different BMI reporting practices on school-level BMI outcomes. BMI的纵向（3年）趋势将与BMI报告的类型有关，以确定不同方法的相对有效性。 AIM 2的目的是评估采用经过验证的基于行为的筛查工具（家庭营养和体育活动筛查工具）以及标准BMI报告的潜力，以促进家庭环境的认识和变化。 Schools will be randomized to receive the standard or supplemental report and effects will be evaluated with surveys and BMI trends. AIM 3的目标是评估基于扩展的家庭教育计划（家庭健身）的有效性，以作为正常BMI筛选程序的扩展。拟议的倡议利用了宾夕法尼亚州内发生的自然实验，回答了有关如何增强BMI筛查有效性的重要问题，BMI筛查的有效性是广泛推荐的公共卫生策略。长期的目标是开发一种证据基础，以促进采用主要的预防策略，以减少身体变化和行为的超重和肥胖风险。 公共卫生相关性：拟议的研究将评估宾夕法尼亚州正在进行的基于学校的BMI筛查计划的BMI轨迹，以确定用于协调肥胖预防计划的最佳实践。将标准BMI成绩单的结果与补充使用基于行为的筛查工具和基于扩展的父母教育计划的结果进行比较，以评估建立家庭环境和实践的策略，以帮助防止孩子超重。该研究将提供有关如何提高学校基于学校BMI筛查计划的有效性的关键见解，BMI筛查计划是一种广泛建议的公共卫生战略。
