Whole-grain consumption and its determinants in Malaysian medical students: A cross-sectional study

ABSTRACT

Background: Whole-grain consumption is associated with several health benefits. Little is known, however, about whole-grain consumption patterns in medical students in Malaysia. 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.
