22. Racial/Ethnic Differences and Health Disparities Objective: The relationship between diet and disease is well established. The elderly population is the fastest growing sub population in the United States. The ability to prevent diet related acute and chronic diseases such as diabetes, hypertension, coronary heart disease and cancer, is particularly important for this group of Americans. Unfortunately efforts to modify individuals' diets by education have been largely unsucessful. Derminants of food purchasing patterns suggest people's dietary choices are affected by their local environments. However the relationship between the local food environment and senior's diets has not been studied. The purpose of this study is to investigate the relationship between the availability and consumption of fruits and vegetables by elderly residents of New York City. Other reseach suggests the elderly are particularly reliant on their local environment for goods and services due to increasing prevalence of disability and decreasing income. Therefore seniors may be a sensitive subpopulation at risk for poor dietary intake when living in a restricted food environment. Methods: A cross sectional study is proposed where eligible elderly participants will be selected from predominately white, predominately black, low and high weath neighborhoods. A sampling scheme has been developed to measure the joint effect of racial segregation and wealth on the location of places that sell fruits and vegetables. Participants will be interviewed over the phone regarding their (a) usual consumption of fruits and vegetables, (b) shopping patterns and (c) access to transportation. In addition, the location of places that sell food in these neighborhoods will be gained from regulatory agencies and food stores will be surveyed for the price and quality of fruits and vegetables sold. We will use a multi-level approach to our statistical analysis to investigate the assocation between the availabilty of fruits and vegetables and comsumption by residents. Conclusions: The results of this reseach will provide more effective intervention strategies for modifying dietary consumption as well as generate hypotheses for future research.

22.种族/民族差异和健康差异 目的：饮食与疾病之间的关系已经很好地建立起来。老年人口是美国增长最快的亚人口。预防与饮食有关的急性和慢性疾病，如糖尿病、高血压、冠心病和癌症的能力，对这一群体的美国人特别重要。不幸的是，通过教育改变个人饮食的努力基本上没有成功。食品购买模式的本质表明，人们的饮食选择受到当地环境的影响。然而，当地的饮食环境与老年人饮食之间的关系尚未得到研究。本研究的目的是调查纽约市老年居民水果和蔬菜的可获得性和消费量之间的关系。其他研究表明， 由于残疾人越来越多，收入越来越少，老年人特别依赖当地环境提供商品和服务。因此，老年人可能是一个敏感的亚群，生活在一个受限制的食物环境中时，饮食摄入量不足的风险。 研究方法：一项横断面研究提出，符合条件的老年人参与者将从主要是白色，主要是黑人，低收入和高收入的社区。已经制定了一个抽样计划，以衡量种族隔离和财富对水果和蔬菜销售地点的共同影响。参与者将通过电话接受采访，了解他们的（a）水果和蔬菜的日常消费，（B）购物模式和（c）交通工具。此外，将从监管机构获得这些社区出售食品的地点，并对食品商店进行调查，以了解所售水果和蔬菜的价格和质量。我们将使用多层次的方法来进行统计分析，以调查水果和蔬菜的可获得性之间的关联， 居民消费。结论：本研究的结果将为改善膳食消费提供更有效的干预策略，并为未来的研究提供假设。
