Abstract：
We examined whether Central Texans shop at their nearest supermarket, how far they travel for groceries, and explored differences by race/ethnicity, urbanicity, motivations for store selection and other demographic characteristics. Using cross-sectional data and GIS, continuous network distances from participants\' homes to nearest and usual supermarkets were calculated and multivariate linear regression assessed differences. <19% shopped at their nearest supermarket. Regression models found that urbanicity played a large role in distance traveled to preferred supermarket, but other factors varied by race/ethnicity. Our findings demonstrate racial/ethnic and urbanicity disparities in food access and multiple domains of food access need greater consideration.
摘要：
我们检查了中部德克萨斯人是否在最近的超市购物，他们去买杂货多远，并探索种族/族裔的差异，城市化，选择商店的动机和其他人口特征。利用横截面数据和GIS，我们计算了从参与者家庭到最近和通常超市的连续网络距离,并采用多元线性回归评估了差异.<19％的人在最近的超市购物。回归模型发现，城市化在前往首选超市的距离中起着重要作用，但其他因素因种族/民族而异。我们的发现表明，食物获取方面的种族/族裔和城市差异以及食物获取的多个领域需要更多地考虑。
