DESCRIPTION (provided by applicant): Obesity among youth tripled in the United States from 1980 to 2000 despite numerous public health interventions designed to educate youth about the benefits of a healthy diet and physical activity. After witnessing the success of public policy adoption targeting other public health issues (e.g. tobacco, bike helmets, seat belts) obesity researchers and policymakers have promoted policy as an intervention tool. The number of state bills and resolutions targeting youth obesity increased substantially in the past decade; however, very little is known about whether these policies have an effect on diet, activity, or BMI. A recent report from NHANES showed that there was no significant increase in average national prevalence of youth obesity between 1999 and 2006. This absence of change, after decades of consistent increases, suggests that policies implemented in the past decade could be having a positive effect. In this research we will use multi-level modeling to examine trends in BMI and weight-related behaviors in high school students within and across states. We will then examine associations between study state level policies for high schools and BMI and weight-related behaviors. Data for this work will be from the Youth Risk Behavior Surveillance (YRBS) and the School Health Programs and Policies Study (SHPPS). The Aims of the research are: Aim 1: To examine between-state differences in youth BMI time trends from 2001-07 and identify demographic and behavioral variables that contribute to the heterogeneity. Aim 2: To estimate the proportion of within-state changes in youth BMI from 2001-07 that is associated with demographic and behavioral changes. Aim 3: To determine if changes in state-level nutrition and physical activity policies from 2000-06 are associated with youth nutrition and physical activity behaviors in 2007. Aim 4: To determine if changes in state-level nutrition and physical activity related policies from 2000-06 are associated with youth BMI and obesity prevalence in 2007. Given the enormity of the destructive effects of the obesity epidemic on the current and future health of American youth, it is surprising that so little work has been done to evaluate the effects of large scale policies. To our knowledge, this will be the first study to merge data from the YRBS to that from SHPPS to estimate the impact of state-level policies on weight-related behaviors and obesity in youth. PUBLIC HEALTH RELEVANCE: We will study state policies effecting high schools to estimate their effects on adolescent behavior and BMI. This will be the most comprehensive study on this topic to date and will advance the field of obesity policy research; a field that has strong potential to impact the health of our youth, but has only just begun.

描述（由申请人提供）：从 1980 年到 2000 年，尽管美国采取了大量公共卫生干预措施来教育年轻人健康饮食和体育活动的好处，但美国年轻人的肥胖率却增加了两倍。在目睹了针对其他公共卫生问题（例如烟草、自行车头盔、安全带）的公共政策的成功采用后，肥胖研究人员和政策制定者提倡将政策作为干预工具。过去十年，针对青少年肥胖问题的州法案和决议数量大幅增加；然而，人们对这些政策是否会对饮食、活动或体重指数产生影响知之甚少。 NHANES 最近的一份报告显示，1999 年至 2006 年间，全国青少年肥胖的平均患病率没有显着增加。经过数十年的持续增长后，这种没有变化的情况表明，过去十年实施的政策可能会产生积极的影响。 在这项研究中，我们将使用多层次模型来研究各州内和跨州高中生的体重指数和体重相关行为的趋势。然后，我们将研究研究州级高中政策与体重指数和体重相关行为之间的关联。这项工作的数据将来自青少年风险行为监测 (YRBS) 和学校健康计划和政策研究 (SHPPS)。该研究的目标是： 目标 1：检查 2001-07 年青年 BMI 时间趋势的州间差异，并确定导致异质性的人口和行为变量。目标 2：估计 2001-07 年州内青少年 BMI 变化与人口和行为变化相关的比例。目标 3：确定 2000-06 年州级营养和身体活动政策的变化是否与 2007 年青少年营养和身体活动行为相关。目标 4：确定 2000-06 年州级营养和身体活动相关政策的变化是否与 2007 年青少年 BMI 和肥胖流行率相关。鉴于肥胖流行对美国人当前和未来健康的巨大破坏性影响 青年人，令人惊讶的是，评估大规模政策效果的工作却如此之少。据我们所知，这将是第一项将 YRBS 数据与 SHPPS 数据合并的研究，以评估州级政策对青少年体重相关行为和肥胖的影响。 公共卫生相关性：我们将研究影响高中的国家政策，以估计其对青少年行为和体重指数的影响。这将是迄今为止关于该主题的最全面的研究，并将推动肥胖政策研究领域的发展；这个领域有很大潜力影响我们年轻人的健康，但才刚刚开始。
