DESCRIPTION (provided by applicant): There is a worldwide pandemic of obesity with far-reaching consequences for the health of our nation. Obesity is the second leading cause of preventable death in the United States. Prevention of obesity, especially in children, has been deemed by public health policy makers to be one of the most important objectives for our country. Obesity disproportionately affects citizens of minority and low socioeconomic status. A consensus of opinion has formed that the recently observed increased prevalence of obesity is caused by environmental and behavioral factors that favor easy access to high calorie foods and sedentary behavior. This prevention project, called LA Health, will test whether modification of these environmental and behavioral factors can prevent inappropriate weight gain in children who are enrolled in the fourth to sixth grades during Year 1. The primary aims of the LA Health project are to test the efficacy of two school-based approaches for obesity prevention. The two approaches are derived from two NIH-funded pilot studies called the HIPTeens project (a secondary prevention program) and the Wise Mind project (a primary prevention program). The study will test the efficacy of primary prevention alone and a combination of primary and secondary prevention in comparison to a no-intervention control group using a cluster randomization research design, with 18 school clusters randomly assigned to the three treatment arms. The project will collaborate with a USDE funded project, LA GEAR UP, to test the relative efficacy of obesity prevention programs for children who come from economically disadvantaged environments. The LA GEAR UP program is designed to enhance educational achievement. Since LA GEAR UP will be implemented in all 18 schools, all of the intervention arms, including no-intervention, will be combined with an academic enhancement program. The study will span three years and will provide critical tests of strategies that modify the child's environment as a primary prevention strategy and provide health behavior modification via classroom instruction and internet counseling as a secondary prevention strategy. The study will also recruit a similar (but smaller) sample of students to measure changes in body weight relative to height, gender, and age over the same three-year period. This observation only control group will be studied to evaluate secular trends in changes in body weight so that body weight changes observed in the randomized trial can be interpreted within the context of stable versus unstable population changes in body weight. The results of this investigation will significantly impact public health policy related to obesity prevention in rural communities, minority communities, and in children from families that are economically disadvantaged.

描述（由申请人提供）：肥胖的全球大流行对我们国家的健康有深远的影响。肥胖是美国可预防死亡的第二大原因。公共卫生政策制定者认为预防肥胖症，尤其是在儿童中，是我们国家最重要的目标之一。肥胖不成比例地影响少数民族和社会经济地位低下的公民。一定的意见已经形成了，最近观察到的肥胖症患病率增加是由环境和行为因素引起的，这些因素有利于轻松获得高卡路里食品和久坐的行为。该预防项目称为LA Health，将测试对这些环境和行为因素的修改是否可以防止在1年级入学四年级至六年级的儿童体重增加不当。LA Health Project的主要目的是测试两种基于学校的预防肥胖方法的方法的功效。这两种方法源自两项名为Hipteens Project（二级预防计划）和Wise Mind Project（主要的预防计划）的两项名为Hipteens Project的试点研究。与使用簇随机研究设计相比，这项研究将仅测试单独预防的疗效，并结合原发性和次要预防的效果，并结合使用簇随机研究设计，并将18个学校簇随机分配给三个治疗臂。该项目将与一个由USDE资助的项目La Gear UP合作，以测试来自经济不利环境的儿童肥胖预防计划的相对效果。 LA Gear UP计划旨在提高教育成就。由于La Gear UP将在所有18所学校中实施，因此所有干预组（包括无干预）将与学术增强计划相结合。该研究将跨三年，并将提供对修改儿童环境作为主要预防策略的策略的重要测试，并通过课堂教学和互联网咨询作为二级预防策略提供健康行为修改。这项研究还将招募一个相似（但较小的）学生样本，以衡量相对于身高，性别和年龄在同一三年期间的体重变化。仅研究该观察结果，以评估体重变化的世俗趋势，以便在随机试验中观察到的体重变化可以在稳定的体重稳定与不稳定的人群变化的背景下解释。这项调查的结果将极大地影响与农村社区，少数民族社区以及来自经济不利的家庭的儿童相关的公共卫生政策。
