Price Effect on Diet and Obesity Risk of Food Assistance Program Recipients

描述(由申请者提供)：食品价格影响个人的食物消费、饮食摄入量和体重状况。这种价格效应在使用粮食援助计划(FAP)的低收入人口中最为显著，该计划的年度预算超过500亿美元。以前的研究表明，参与FAP直接影响个人的营养状况和体重状况。然而，关于食品价格如何影响FAP参与者的食品消费和健康结果，人们的理解有限。该应用程序的长期目标是确定促进低收入美国人体重增加的经济机制。此应用程序的目的是检查食品价格对FAP参与者、参与者的饮食和肥胖风险的影响。这项拟议的研究支持了美国国立卫生研究院的使命，即鼓励采用多学科方法来研究导致肥胖的因素。这项研究的结果将用于设计和实施FAP，以应对美国日益增长的肥胖症流行。这一目标将通过三个具体目标来实现： 具体目标1：研究当地食品价格和生活成本对FAP参与的影响。这一目标将通过对全国青年纵向调查(NLSY)与美国商会研究人员协会(阿克拉)价格数据集的纵向分析来实现。FAP的参与将是主要的结果衡量标准。约200个大都市的生活成本指数和食品杂货指数将成为解释变量。 具体目标2：考察当地食品价格对FAP参与者饮食摄入量的影响。低成本的不健康食品导致了低收入人群中肥胖的流行。然而，低食品价格对防止营养不良很重要。因此，了解食品价格如何影响FAP参与者的营养状况是很重要的。这一目标将通过将国家健康和营养检查调查(NHANES)数据集与阿克拉价格数据集联系起来实现。 具体目标3：衡量当地食品价格对FAP参与者的BMI和肥胖风险的影响。参与FAP可以对成人和儿童的体重增加做出积极贡献。但人们对当地食品价格与FAP参与者的体重状况和肥胖风险之间的关系知之甚少。这项拟议的研究意义重大，因为它将有助于确定当地食品价格与FAP参与者的体重状况和肥胖风险之间的关系。确定价格对FAP参与者的饮食和健康结果的影响将具有重要的政策意义。

DESCRIPTION (provided by applicant): Food prices affect an individual's food consumption, dietary intake, and body weight status. This price effect is most significant among the low-income population that uses food assistance programs (FAP), the annual budget of which is over $50 billion dollars. Previous studies suggest that FAP participation directly affects an individual's nutritional status and body weight status. However, there is a limited understanding regarding how food prices affect FAP participants' food consumption and health outcomes. This application's long term goal is to identify the economic mechanisms that promote weight gain among low-income Americans. The objective of this application is to examine the effects of food prices on FAP participation, participants' diet, and risk of obesity. The proposed study supports the National Institutes of Health's mission that encourages a multidisciplinary approach for studying factors that contribute to obesity. Results of the study will build to design and implement FAPs that will confront the growing obesity epidemic in the U.S. The objective will be pursued through three specific aims: Specific Aim #1: To study the effect of local food prices and cost of living on FAP participation. This aim will be accomplished through longitudinal analysis of the linked National Longitudinal Survey of Youth (NLSY) with the American Chamber of Commerce Researchers' Association (ACCRA) price dataset. FAP participation will be the primary outcome measures. Cost of living indices and grocery indices around 200 metropolitan areas will be the explanatory variables. Specific Aim #2: To examine the effect of local food prices on FAP participants' dietary intakes. Low cost of unhealthy food has contributed to the obesity epidemic among the low-income population. However, low food prices are important to prevent malnutrition. Therefore, it is important to understand how food prices affect FAP participants' nutritional status. This aim will be accomplished by linking data from the National Health and Nutritional Examination Survey (NHANES) dataset with the ACCRA price dataset. Specific Aim #3: To measure the effects of local food prices on FAP participants' BMI and risk of obesity. FAP participation can positively contribute to weight gain among adults and children. But little is known about the relationship between local food prices and FAP participants' body weight status and risk of obesity. The proposed research is significant because it will facilitate the determination of the relationship between local food prices and FAP participants' body weight status and risk of obesity. Identification of price effect on FAP participants' diet and health outcomes will have important policy implications.
