Adherence to a Mediterranean-style diet is associated with an extensive list of health benefits for people both with and without a disease.
The objective of this study was to develop/modify a questionnaire to investigate the current adherence to a Mediterranean-style dietary eating pattern amongst the New Zealand male population, and to assess the association between perceived barriers to change and behaviours.
The development of this questionnaire was based upon a modified 14-point validated Mediterranean diet adherence screener (PREDiMED) and included an additional section wherein we explored the reasons behind men’s food choices and barriers to healthy eating. Questionnaires were analysed from 295 men. Descriptive analyses were used to determine major barriers to change.
The modification of the PREDiMED questionnaire resulted in a 23 question questionnaire encompassing adherence, demographics and barriers to change. We found that 90.8% of respondents had either low or intermediate adherence to a Mediterranean style diet. Significant associations also existed between adherence and smoking (p=0.003), age (p< 0.01) and opinion of the importance of healthy eating (p< 0.01). We found participants felt the ‘major’ barrier to consume a healthy diet, to be a busy lifestyle, and the most common influencer of food choices was people.
Through identifying how New Zealand men consume food and how they consider their barriers to change, we can better direct policy to aid changes in behaviour and integrate the Mediterranean style diet to complement the New Zealand food culture.
