DESCRIPTION (provided by applicant): Low access to healthy food is associated with poor diet and increased obesity. The scarcity of healthy food outlets in disadvantaged communities has led to local and national initiatives to increase healthy food access. It is unknown if locatin supermarkets or other outlets for healthy foods in these areas, called "food deserts," will improve diet quality. One such food outlet is the food hub, an outlet for locally produced food that typically have healthy food access, local food security, economic development and community education and training as goals. They are an alternative to supermarket chains that are often unwilling to locate in areas of high poverty. The goal of this research is to evaluate th impact of a food hub in a food desert community in South Carolina. The food hub will include a farmers' market, urban farm, mobile market, cafe and classrooms for community nutrition education and culinary arts job training. It will employ 23 local people and seeks to increase access to local produce and other food products produced on-site. The study will enroll 280 primary food shoppers from the surrounding community and 280 from a control group from a distant community matched on characteristics such as poverty, racial composition and access to healthy food. In-person interviews will be conducted with the 560 participants before the food hub's opening and again at 12 and 24 months to assess dietary intake, body weight, perceptions of the community food environment and food shopping habits, as well as a number of other social and attitudinal measures related to dietary choices. Global Positioning System and Geographic Information Systems technology will be use to assess the two communities' food environment and to calculate measures such as distance from participants' residences to various types of food outlets (for example, grocery store, convenience store, farmers' market , and fast food restaurant). Additional analyses of sales figures and questionnaires from shoppers present on randomly selected days at the food hub's farmers' market will indicate if residents of the surrounding food desert represent an increasing proportion of customers. Community leaders will provide their impressions of the food hub's impact on the community and its successes and challenges through focus groups and interviews.

描述(由申请人提供)：健康食品获取机会少与不良饮食和肥胖增加有关。由于弱势社区缺乏健康食品销售点，地方和国家采取了增加健康食品供应的举措。目前尚不清楚，在这些地区，定位超市或其他健康食品销售点，即“食品沙漠”，是否会改善饮食质量。一个这样的食品渠道是食品中心，这是一个当地生产的食品的渠道，通常以健康食品获取、当地食品安全、经济发展以及社区教育和培训为目标。它们是超市连锁店的替代方案，这些超市连锁店往往不愿在高度贫困的地区落户。这项研究的目的是评估在南卡罗来纳州的食物沙漠社区建立食物中心的影响。食品中心将包括农贸市场、城市农场、流动市场、咖啡馆和教室，用于社区营养教育和烹饪艺术职业培训。它将雇用23名当地人，并寻求增加获得当地农产品和其他现场生产的食品的机会。这项研究将从周围社区招募280名主食购买者，并从遥远社区的280名控制组招募，这些购物者在贫困、种族构成和获得健康食品等特征上匹配。在食品中心开业前，以及在12个月和24个月时，将与560名参与者进行面对面访谈，以评估饮食摄入量、体重、对社区食品环境和食品购物习惯的看法，以及与饮食选择有关的其他一些社会和态度衡量标准。全球定位系统和地理信息系统技术将用于评估两个社区的食物环境，并计算参与者住所到各种食品店(例如杂货店、便利店、农贸市场和快餐店)的距离。对销售数据的额外分析，以及随机选择几天出现在食品中心农贸市场的购物者的问卷调查，将表明周围食品沙漠的居民是否代表着越来越多的顾客。社区领导人将通过焦点小组和采访，提供他们对食品中心对社区的影响以及它的成功和挑战的印象。
