英文文献摘要：
In this research, we examine if and how altering the scale at which access is defined changes the estimated impact of access on diet quality and health outcomes. We also examine the extent to which there is a gradient between distance to the nearest supermarket and diet-related outcomes and whether availability of less healthy food outlets, such as convenience stores, alter any possible relationship between access and diet and health outcomes.
