  • The Short- and Long-term Effectiveness of the WhyDairy' School-based
           Nutrition Education Intervention: A Randomized Controlled Trial

    • Abstract: Background:Despite the known health benefits of dairy products, their daily consumption continues to decline in many populations, particularly in pre-adolescents and adolescents.Objective:The primary objective of the cluster randomized controlled trial was to assess whether a school-based intervention enhanced with a web-based component, known as WhyDairy' was more effective than a standardized dairy education program at changing: (i) knowledge of dairy products, (ii) intentions to consume dairy products, and (iii) dietary intake of dairy products.Methods:Grade 7 students (n=175) in 10 Southwestern Ontario schools were randomized by the school, into intervention or control. Intervention schools received the WhyDairy' intervention with a website component while control schools received a DFO education program. Intervention schools were further randomized to receive follow-up contact, through monthly emails, or no follow-up contact. A questionnaire, consisting of three surveys (knowledge, FFQ, and intention), was delivered at baseline, post-intervention, and follow-up.Results:All groups significantly increased their knowledge post-intervention but only intervention schools with follow-up email contact maintained this positive change in knowledge. No groups saw significant changes in dietary behaviour. The email campaign was successful in reaching parents but did not result in high engagement or changes in student outcomes.Conclusion:The results of this study demonstrate the effectiveness of a school-based intervention enhanced with a web-based component in changing student knowledge regarding dairy products and the engagement of the website during the intervention period. Future work should consider longer durations to see changes in dietary behaviour and more targeted approaches during follow-up periods.
  • A Questionnaire-based Assessment of Dietary Adherence and Identification
           of Barriers to Healthy Eating

    • Abstract: Background:Adherence to a Mediterranean-style diet is associated with an extensive list of health benefits for people both with and without a disease.Objective: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.Methods: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.Results: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 (=0.003), age (< 0.01) and opinion of the importance of healthy eating (< 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.Conclusion: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.
