: There is limited longitudinal evidence supporting a link between food outlet locations and dietary outcomes to inform policy and urban planning. This study examined how longitudinal changes in the local food environment within new residential developments influenced changes in adult dietary intake. : Adult participant data (n = 3223 person-observations) were sourced from the RESIDential Environments (RESIDE) project across three time points between 2004 to 2012 in Perth, Western Australia. Fixed effects regression estimated the relationship between change in spatial exposure to the local food environment, individual behaviours and perceptions of the local food environment with dietary outcome variables (healthy diet score, unhealthy diet score, diet quality score and fruit/vegetable intake). : An increase over time in the percentage of healthy food outlets around the home was significantly ( ≤ 0.05) associated with an increase in healthy diet scores and an increase in the distance from home to the nearest café restaurant was significantly ( ≤ 0.05) associated with an increase in diet quality scores. : Modifying the local food environment by increasing the relative proportion of healthy food outlets around the home may support healthier dietary intake.
：目前，能够为政策和城市规划提供依据的、有关食品店位置与饮食结果之间关系的纵向证据十分有限。本研究旨在探究新住宅开发项目内部的当地食品环境的纵向变化，对成年人饮食摄入的变化会产生怎样的影响。：从澳大利亚珀斯的 RESIDential Environments（RESIDE）项目中，获取了 2004 年至 2012 年三个时间点的成年参与者数据（n = 3223 人-观测）。固定效应回归估计了当地食品环境的空间暴露变化、个体行为以及对当地食品环境的感知与饮食结果变量（健康饮食评分、不健康饮食评分、饮食质量评分和水果/蔬菜摄入量）之间的关系。：随着时间的推移，家庭周围健康食品店的比例增加，与健康饮食评分的增加显著相关（≤0.05）；而离家最近的咖啡馆/餐馆的距离增加，则与饮食质量评分的增加显著相关（≤0.05）。：通过增加家庭周围健康食品店的相对比例来改善当地食品环境，可能有助于促进更健康的饮食摄入。
