Sommaire de l'article

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.

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.

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.
