OBJECTIVES To assess (i) understanding, acceptability and preference for two graphical displays of the Mediterranean diet (MD); and (ii) feasibility of a brief MD intervention and cost of adherence to this diet among British older adults. DESIGN Two studies undertaken at the Human Nutrition Research Centre, Newcastle University are reported. In study-1, preference and understanding of the MD guidelines and two graphical displays, a plate and a pyramid, were evaluated in an educational group session (EGS). In study-2, we evaluated the feasibility of a three-week brief MD intervention with two levels of dietary advice: Group-1 (level 1) attended an EGS on the MD, and Group-2 (level 2) attended an EGS and received additional support. MD adherence using a 9-point score, and the cost of food intake during intervention, were assessed. RESULTS STUDY-1: No differences in preference for a MD plate or pyramid were observed. Both graphic displays were rated as acceptable and conveyed clearly these guidelines. STUDY-2: The intervention was rated as acceptable. No significant differences were observed between groups 1 and 2. Analysis of the combined sample showed significant increases from baseline in fish intake (P=0.01) and MD score (P=0.05). The cost of food intake during intervention was not significantly different from baseline. CONCLUSION British older adults rated a MD as an acceptable model of healthy eating, and a plate and a pyramid as comprehensible graphic displays of these guidelines. A brief dietary intervention was also acceptable and revealed that greater adherence to the MD could be achieved without incurring significantly greater costs.

英国老年人的地中海饮食：具有两个饮食建议水平的随机简短干预的理解、可接受性和可行性

目标 评估 (i) 对地中海饮食 (MD) 的两个图形显示的理解、可接受性和偏好；(ii) 在英国老年人中进行简短 MD 干预的可行性和坚持这种饮食的成本。设计报告了在纽卡斯尔大学人类营养研究中心进行的两项研究。在研究 1 中，在一个教育小组会议 (EGS) 中评估了对 MD 指南和两个图形显示（一个盘子和一个金字塔）的偏好和理解。在研究 2 中，我们评估了为期三周的简短 MD 干预和两个级别的饮食建议的可行性：第 1 组（第 1 级）参加了关于 MD 的 EGS，第 2 组（第 2 级）参加了 EGS 和获得了额外的支持。使用 9 分评分对 MD 依从性和干预期间的食物摄入成本进行了评估。结果研究-1：没有观察到对 MD 板或金字塔的偏好差异。两种图形显示都被评为可接受并清楚地传达了这些指导方针。研究 2：干预被评为可接受。第 1 组和第 2 组之间未观察到显着差异。对组合样本的分析显示，鱼类摄入量（P=0.01）和 MD 评分（P=0.05）较基线显着增加。干预期间的食物摄入成本与基线没有显着差异。结论 英国老年人将 MD 评为可接受的健康饮食模式，将盘子和金字塔视为这些指南的可理解图形显示。简短的饮食干预也是可以接受的，并表明可以在不产生显着增加成本的情况下实现对 MD 的更大依从性。
