Increasing fruit and vegetable intake has the potential to prevent chronic disease risk but substantial inequalities in intake exist between advantaged and disadvantaged communities. Access and availability of fruit and vegetables have been shown to be important determinants of intake. The current study aimed to evaluate the effectiveness of a Mobile Food Store intervention to improve access to fruit and vegetables by making cost-price produce available to targeted communities. Postcode mapping identified communities with low fruit and vegetable intake and high chronic disease risk. The Mobile Food Store travelled to these communities each week. Evaluation of self-reported fruit and vegetable intake was collected by validated questionnaire for 255 users (62% response rate). Store use resulted in a significant increase in intake (1.2 portions per day, 95%CI 0.83-1.48; p<0.001) which was greater than all but one previous intervention in the UK. The targeted model of improving access to fruit and vegetables was effective in increasing intake; however future controlled trials are required to objectively examine potential effects on fruit and vegetable intake and health outcomes.
增加水果和蔬菜的摄入量有可能预防慢性病风险，但在优势和劣势社区之间，摄入量存在着巨大的不平等。水果和蔬菜的获取和可得性已被证明是摄入量的重要决定因素。本研究旨在评估移动食品商店干预措施的有效性，该措施通过以成本价向目标社区提供农产品来增加水果和蔬菜的获取机会。邮政编码映射确定了水果和蔬菜摄入量低且慢性病风险高的社区。移动食品商店每周都会前往这些社区。通过经过验证的问卷，对 255 名用户（62%的回应率）的自我报告的水果和蔬菜摄入量进行了评估。商店的使用导致摄入量显著增加（每天 1.2 份，95%CI 0.83-1.48；p<0.001），这比英国以前的所有干预措施都要大。改善水果和蔬菜获取机会的目标模式在增加摄入量方面是有效的；然而，需要进行未来的对照试验，以客观地检查对水果和蔬菜摄入量和健康结果的潜在影响。
