Objectives: The study was conducted to assess whole-grain intake pattern and factors influencing intake among Malaysian medical students.
Methods: A cross-sectional study investigating whole-grain intake among 151 medical students in a private medical university in Malaysia was conducted from January to June 2018. A self-administered questionnaire was used to assess sociodemographic variables, the whole-grain intake pattern and the knowledge and attitudes toward whole-grain intake. Data were analyzed using IBM SPSS software. Chi-square test and multivariable logistic regression were used.
Results: The prevalence of reported whole-grain intake in the past 3 months was 51%. Chinese ethnicity, readiness to adhere to Malaysian food pyramid, and self-preparation of food, and eating at home were significantly associated with whole-grain consumption. However, the primary determinants of food choice such as education, knowledge, and affordability did not seem to influence whole-grain consumption. Whole-grain consumption is relatively low among Malaysian medical students. Cultural background and self-belief influence this practice despite being from the medical fraternity.
Conclusions: Efforts are needed to bridge the knowledge-practice gap by assessing the barriers to whole-grain consumption to design effective initiatives to promote an increase in whole-grain consumption.
MATERIALS AND METHODS: A systematic search for existing guidelines on TDI was performed on PubMed, EMBASE, CINAHL, Cochrane Library, ProQuest, National Institute for Health Care Excellence, BMJ Best Practice, Trip database, Guideline International Network, Scottish Intercollegiate Guidelines Network, World Health Organisation, Web of Science and 'Ministry of Health worldwide' databases. Four appraisers independently appraised the included CPGs. The AGREE II tool was applied to assess the methodological quality, while AGREE REX assessed the quality of recommendations of the included guidelines.
RESULTS: Of the 7736 titles screened, three guidelines, namely the International Association of Dental Traumatology Guidelines (IADT), and the Italian and Malaysian guidelines, were included for the final analysis. These guidelines were published between 2019 and 2020. The AGREE II analysis demonstrated scores above 80% for the IADT and Italian guidelines for the scope and purpose domain. Overall, the Malaysian guidelines achieved the highest score for all domains. The AGREE REX analysis indicated variability in implementation across the nine items, with five that scored above the midpoint of 4.0 on the response scale. Both the Italian and the IADT guidelines had a similar score for the values and preference domains (36.36%).
CONCLUSIONS: Several deficiencies exist in the methodological quality of existing CPGs on TDI. Future guidelines should consider improvements for domains such as 'rigour of development', 'stakeholder involvement' and 'applicability' to overcome the existing limitations.
