项目摘要

DESCRIPTION (provided by applicant): Improving diet quality is a central component in the fight against obesity. One hotly debated topic is the role of prices for healthy foods and nutritionally less desirable foods, but little data is available. Congress has asked USDA to conduct a pilot study that provides discounts on healthy foods, but this project has not started yet and will be limited to selected individuals in a single county in Massachusetts. We propose to analyze data from a much larger program that was started in 2009 by the South African health insurance company Discovery. Discovery's HealthyFood program provides rebate of up to 25% on healthy items through a nationwide supermarket chain and presently enrolls about 200,000 households. Food items eligible for a discount on the HealthyFood benefit were selected in agreement with international and US dietary guidelines and are marked on cash register receipts and on the shelves. We will consider the overall impact of the program on purchases, diets, and health outcomes, and also try to separate out the effects of the financial incentives from the educational component and environmental changes that affect the whole population. Our primary statistical approach is difference-in-difference analysis (pre/post of individuals becoming eligible for benefit with control groups), complemented with additional statistical analyses to address selection biases. Data sources include both individual health surveys, sales data from supermarkets (individual line items and linkable to individuals), and health care claims. PUBLIC HEALTH RELEVANCE: This project will evaluate a program that addresses a central issue to improve diet and prevent obesity: What if healthy foods were cheaper? About 200,000 households are currently enrolled in Discovery's HealthyFoodbenefit, a program that gives them a substantial rebate on their healthy food purchases. By studying changes in purchasing behavior, in self-reported diets, and in other health outcomes among HealthyFoodparticipants and a control group, we will be able to provide the first results on what meaningful price changes for healthier foods could achieve at the population level.

描述（由申请人提供）：提高饮食质量是对抗肥胖症的核心组成部分。一个备受争议的话题是健康食品价格的作用，营养上的食品较少，但很少有数据。国会已要求美国农业部进行一项试点研究，以提供有关健康食品的折扣，但是该项目尚未开始，并且将仅限于马萨诸塞州一个县的选定个人。我们建议分析南非健康保险公司Discovery于2009年启动的一个更大计划的数据。 Discovery的Healthyfood计划通过全国性的超市连锁店可为健康物品提供高达25％的折扣，目前约有200,000户家庭。与国际和美国饮食指南一致，选择了有资格获得Healthyfood福利折扣的食品，并在收银机和货架上标记。我们将考虑该计划对购买，饮食和健康成果的总体影响，并尝试将经济激励措施与影响整个人群的教育组成部分和环境变化分开。我们的主要统计方法是差异差异分析（个体的前/职位，有资格获得对照组的利益），并进行了其他统计分析以解决选择偏见的其他统计分析。数据源包括个人健康调查，超级市场（单个订单项目和与个人链接）的销售数据以及医疗保健索赔。公共卫生相关性：该项目将评估一项针对改善饮食和预防肥胖症的核心问题的计划：如果健康食品更便宜，该怎么办？目前约有200,000户家庭正在加入Discovery的HealthyFoodBenefit，该计划使他们对健康食品的购买有很大的回扣。通过研究购买行为的变化，自我报告的饮食以及在健康食品组成部分和对照组之间的其他健康状况中，我们将能够提供第一个结果，以了解在人群水平上更健康食品的有意义价格变化。
