Aim: To assess the role of breakfast, BMI and English Language Proficiency on academic performance of undergraduate students. Objective: To investigate the trend of skipping breakfast among students, to calculate the BMI of undergraduate students and to assess the level of proficiency of English Language through English test and to relate all these parameters to academic performance.

Methodology: The sample population was chosen from the undergraduate students in PIDC which involved 68 undergraduate students. All respondents chosen were willing to complete survey questions including a test given and were of Year Three and Year Four dental students who had have completed their respective final year exams and obtained their CGPA. For data collection, these students were given the questionnaire and an English test in the morning which were completed within an hour. The questionnaire was to assess their breakfast habits and BMI while the English test was to assess their English language proficiency. The questionnaire had two parts and after the chosen respondents had answered the questions, they then took the English Proficiency test. Data collected were analysed with SPSS for Pearson correlation and p-values.

Results: 61.76% of students were non-breakfast skippers with 38.24% being breakfast skippers, 51.47% of students scored excellent in English test, 19.12% scored very good, 17.65% scored good and remaining 11.76% scored satisfactory. According to the BMI scale, 70.59% of students belonged to normal BMI category, 17.65% belonged to obese category, 8.82% belonged to underweight category and the remaining 2.94% belonged to the severely underweight category. According to Pearson Correlation test, it was found that there were significant correlations between breakfast habit and English language proficiency to academic performance. However, for BMI there was a weak correlation to academic performance. Conclusion: There were significant correlations between breakfast habit and English language proficiency to academic performance of undergraduates in PIDC. However, the study showed a non-significant correlation between BMI to academic performance. Since the p-value is less than our chosen signification alpha value= 0.05, we rejected the null hypothesis and concluded that academic performance is dependent on breakfast habit and English Language proficiency in undergraduates of Penang International Dental College. We would like to emphasize on the importance of promoting and implementing strategies that focus on breakfast intake and English language proficiency in students including primary and secondary school youths as academic performance should be enhanced since young age. Nutritional health programs and English book fairs can be carried out in those schools in order to achieve this.
