DESCRIPTION (provided by applicant): In this pilot study, we propose a two-arm primary prevention trial to test the efficacy of an environmental approach for the prevention of obesity in children who are in the second through sixth grades. An attention-placebo control group will receive an environmental approach for the prevention of alcohol drug tobacco use and abuse. This test of an environmental approach targets a school system for change. Four schools with a total of approximately 1,040 students will be the participants in the study. The four schools will be randomly assigned to one of the two treatment arms. The prevention study will be conducted across two consecutive academic years. The primary endpoint will be body mass index. The primary aim of the study is to test the efficacy of the obesity program for the prevention of weight gain in children. Changes in dietary intake and physical activity will be tested as mediators of changes in body mass index. Also, age of the child, initial body mass index, and gender will be tested as factors that are associated with differential outcomes related to the prevention of weight gain. Secondary endpoints include: body composition, waist circumference, physical activity, dietary intake, body image, mood, and self-esteem. The environmental program for the prevention of obesity will have multiple components that are designed to alter automatic/habitual decision making by students. The results of this pilot study will guide the development of full-scale investigations in a larger set of schools. The findings of the study will have significant impact upon public health policy regarding prevention of obesity. Several innovations are utilized in the study, including novel applications of the internet to provide environmental prompts to parents and families, and the use of a new method, called digital photography of foods, for measurement of the food selections and food intake of individual students, in school cafeterias.

描述（由申请人提供）： 在这项试点研究中，我们提出了一项两臂初级预防试验，以测试环境方法在二年级至六年级的儿童中预防肥胖症的疗效。一个注意地位对照组将获得一种环境方法，以预防酒精烟草使用和滥用。这种环境方法的测试目标是学校系统进行变革。这项研究的参与者将是四所拥有约1,040名学生的学校。这四所学校将被随机分配到两个治疗臂之一。预防研究将在连续两个学年进行。主要终点是体重指数。该研究的主要目的是测试肥胖计划预防儿童体重增加的功效。饮食摄入和体育锻炼的变化将作为体重指数变化的介体进行测试。同样，儿童的年龄，初始体重指数和性别将被测试为与与预防体重增加有关的差异结果相关的因素。次要终点包括：身体成分，腰围，体育锻炼，饮食摄入，身体形象，情绪和自尊。预防肥胖的环境计划将具有多个旨在改变学生自动/习惯决策的组件。这项试点研究的结果将指导在较大的学校中进行全面调查的发展。该研究的发现将对预防肥胖症的公共卫生政策产生重大影响。该研究中利用了几项创新，包括互联网的新应用以向家长和家庭提供环境提示，以及使用一种称为食品数字摄影的新方法，用于测量学校自助餐厅的食物选择和食物摄入量。
