DESCRIPTION (provided by applicant): One factor that is likely an important contributor to the dramatic rise in overweight and obesity in the U.S. over the past 20 years is the increase in the number of meals and snacks eaten away from home. In recognition of the importance of foods eaten away from home on energy intake and body weight, a number of strategies to promote more healthful food choices while eating out have been proposed, including a number of environmental changes that may have broad public health implications. The overall goal of the proposed study is to examine the potential effectiveness of two promising environmental approaches to encourage lower energy and fat intake while eating away from home. Specifically, the aims of this study are to 1.) Determine whether the provision of nutrition information (energy and fat) on a fast food restaurant menu results in the selection and consumption of lower calorie and lower fat meals; 2.) Compare the calorie and fat content of meals selected from a fast food restaurant menu that includes value size pricing and a menu that does not include value size pricing; 3.) Determine whether the effect of point of purchase nutrition information for fast food restaurant menu items on food selection and consumption is modified by value size pricing; 4.) Examine possible differences in the effect of point of purchase nutrition information and value size pricing on food selection and consumption by age (adolescents versus adults); and 5.) Characterize the food and nutrition-related attitudes, beliefs, and practices of a sample of regular fast food restaurant consumers. To address these aims we propose to conduct a randomized controlled 2x2 factorial experiment in which subjects will select a fast food restaurant meal from one of four menus that will vary with respect to whether nutrition information is provided (yes/no) and whether value size pricing is used (yes/no). Study participants will include adolescents and adults who eat regularly at fast food restaurants. Study staff will record the foods selected, received, and consumed by each participant, thus providing information needed to compare the energy and fat composition of the meals selected and consumed by experimental condition. This study builds on previous intervention research on point of purchase nutrition information and price incentives to provide new unique information that may have broad public health implications.

描述（由申请人提供）：一个因素可能是美国过去20年中超重和肥胖症急剧上升的重要原因的一个因素是，饮食和小吃的数量增加了。为了意识到食物在能量摄入和体重上的食用的重要性，已经提出了许多在外出就餐时促进更健康食品选择的策略，包括许多可能具有广泛公共卫生影响的环境变化。拟议的研究的总体目标是研究两种有希望的环境方法的潜在有效性，以鼓励在外出吃饭时降低能量和脂肪的摄入量。具体而言，这项研究的目的是1.）确定在快餐餐厅菜单上提供营养信息（能量和脂肪）是否会导致选择和消费较低的卡路里和较低的脂肪饮食； 2.）比较从快餐餐厅菜单中选择的餐点的卡路里和脂肪含量，其中包括价值尺寸的价格和不包括价值尺寸定价的菜单； 3.）确定购买点餐厅菜单项的购买营养信息对食物选择和消费的影响是否通过价值尺寸定价来修改； 4.）检查购买营养信息点的影响和价值尺寸定价对食物选择和消费量的可能差异（青少年与成人）；和5.）表征了常规快餐店消费者样本的食物和营养相关态度，信念和做法。为了解决这些目标，我们建议进行随机控制的2x2阶乘实验，其中受试者将从四个菜单之一中选择快餐餐厅用餐，这些菜单将因提供营养信息而有所不同（是/否）以及是否使用了价值尺寸的价格（是/否）。学习参与者将包括在快餐店定期吃饭的青少年和成年人。学习人员将记录每个参与者所选的，接收和消费的食物，从而提供比较通过实验条件选择和消费的餐食的能量和脂肪组成所需的信息。这项研究基于以前关于购买营养信息和价格激励措施的干预研究，以提供可能具有广泛公共健康影响的新独特信息。
