This thesis aimed to assess the feasibility of peer support (PS) for encouraging adoption and maintenance of a Mediterranean diet (MD) in a Northern European population at high CVD risk. It consists of (i) a systematic review of the effect of PS in encouraging dietary change in adults; (ii) qualitative analysis of barriers to a MD in a Northern European population; (iii) validation of a Mediterranean diet score (MDS) to assess MD adherence in a Northern European population and (iv) development and interim-analysis of a pilot RCT to assess the effectiveness of PS for encouraging MD adoption and maintenance in a Northern European population at high CVD risk (TEAM-MED study). The systematic review found that more studies reported a positive effect of PS or mixed results, than studies that did not find an effect of PS for achieving dietary change. However, as evidence was mixed, the effect of PS in encouraging dietary change in adults is not clear and further information is needed. Individuals at high risk of CVD from a Northern European population showed preference towards a group based PS model which was developed for assessment in the TEAM-MED study. Qualitative research among this population indicated a limited knowledge of, and a number of barriers towards consuming a MD which were addressed in the development of the TEAM-MED study. Validation of the TEAM-MED study MDS deemed this to be a reliable tool for assessing MD adherence among Northern European populations. The TEAM-MED study interim-analysis demonstrated that there was no significant difference in MD adherence between the PS, minimal and proven intensive intervention groups. Full analysis of the TEAM-MED study will confirm these results. While evidence is not yet clear, PS has the potential to encourage dietary change towards a MD in Northern European populations.
