城市农业（UA），即在城市和城市周边地区种植水果和蔬菜，可以在广泛和个人范围内改善粮食安全和获取，公共卫生和饮食质量。然而，关于尿酸与饮食关系的研究很少，潜在的介导因素也不清楚。这项研究旨在调查是否接近和参与UA与更好的饮食质量有关，以及这种关系的原因是什么。英国的成年人（N = 583，69%女性）在一项在线调查中完成了对UA的接近度和参与度、对水果和蔬菜的感知、健康和道德食品选择动机、与自然的联系、心理困扰和饮食质量的测量。参与者是从普遍获得相关团体和公众中招募的。建议的关系进行了分析，使用结构方程模型。更接近和参与UA与更多的水果和蔬菜，更多的健康相关的食物选择动机，更多的道德相关的食物选择，感觉与自然的联系更紧密，令人惊讶的是，更大的心理困扰。此外，通过健康和道德相关的食物选择动机，接近和参与UA与更好的饮食质量间接相关。虽然接近和参与UA与饮食质量之间的直接途径并不显着，但UA与更好的饮食质量相关，部分原因是通过更健康和道德的食物选择动机。通过这些因素，提高UA可能对饮食质量有益，需要更多的研究来测试因果关系并了解这些复杂的相互作用。
Urban agriculture (UA), the growing of fruits and vegetables in urban and peri-urban areas, may improve food security and access, public health and dietary quality on both a broad and personal scale. However, there is little research on the relationship between UA and diet, and potential mediating factors are also unclear. This study aimed to investigate if proximity to and engagement with UA is associated with better diet quality, and what accounts for this relationship. UK-based adults (N = 583, 69% Female) completed measures of proximity to and engagement with UA, perceived access to fruits and vegetables, health and ethical food choice motivations, connection with nature, psychological distress and dietary quality in an online survey. Participants were recruited from UA-related groups and the general public. Proposed relationships were analysed using a structural equation model. Greater proximity to and engagement with UA was associated with greater perceived access to fruits and vegetables, more health-related food choice motivations, more ethical-related food choice, feeling more connected with nature, and, surprisingly greater psychological distress. Furthermore, proximity to and engagement with UA was indirectly associated with better diet quality via health-, and ethical-related, food choice motivations. While the direct pathway between proximity to and engagement with UA and diet quality was not significant, UA is associated with better diet quality, partly via healthier and ethical food choice motivations. Upscaling UA may have benefits for dietary quality via these factors, and more research is needed to test causal relationships and understand these complex interactions.
