目的：为了研究家庭和零售食品环境和水果和蔬菜（FV）的摄入量在城市和农村的环境context.Design：采用横断面设计的措施之间的关系。通过调查仪器收集FV摄入量和其他特征的数据，并根据地面真实数据对客观食物环境进行地理编码。（挡风玻璃审计）调查的零售食品环境。设置：一个城市和6个相邻的农村县。参与者：这项研究涉及2,556名居民的布拉索斯谷，得克萨斯州，谁是通过随机数字拨号选择。主要结果测量：FV摄入量的两项量表。分析：数据采用卡方分析、双样本t检验和线性回归进行分析。结果：距离超市或购物中心在城市模型中不显著，但在农村模型中显著（β = -.014，P < .010，置信区间= -.024，-.003）。结论和启示：零售食品环境对城市和农村的FV摄入有不同的影响。干预措施，以提高FV摄入量在这些设置应占的重要性，距离零售食品环境在农村设置。
Objective: To examine the relationship between measures of the household and retail food environments and fruit and vegetable (FV) intake in both urban and rural environmental contexts.Design: A cross-sectional design was used. Data for FV intake and other characteristics were collected via survey instrument and geocoded to the objective food environment based on a ground-truthed (windshield audit) survey of the retail food environment.Setting: One urban and 6 contiguous rural counties.Participants: This study involved 2,556 residents of the Brazos Valley, Texas, who were selected through random-digit dialing.Main Outcome Measure: Two-item scale of FV intake.Analysis: Data were analyzed using chi-square analysis, 2-sample t tests, and linear regression.Results: Distance to supermarket or supercenter was insignificant in the urban model, but significant in the rural model (beta = -.014, P < .010, confidence interval = -.024, -.003).Conclusions and Implications: Retail food environments have different impacts on FV intake in urban and rural settings. Interventions to improve FV intake in these settings should account for the importance of distance to the retail food environment in rural settings.
