Breakfast consumption is correlated with a range of positive outcomes, namely good academic performance, appropriate nutrient intake and body mass index (BMI). However, many university students have the habits of skipping breakfast and consume insufficient amount of nutrients. The aim of this study was to determine the relationship between the behaviour of skipping breakfast and dietary intake with BMI among students of a private university in Shah Alam, Malaysia. A cross sectional study was performed among 200 students, using a self-administered questionnaire. The questionnaire consisted of socio-demographics, dietary habits and 24-hour recall food intake. The data was analysed using SPSS and Nutritionist pro software. A total of 58% students (60% male and 56% female) had the habit of breakfast skipping. The common reason of student skipping breakfast is do not have time (n = 146; 73%). Most of the respondents taking more than 2500kcal daily were overweight. The results showed no significant association (p = 0.831) between breakfast skipping and BMI. There was no significant association (p > 0.05) between covariates (socio-demography, anthropometry, intakes of protein, carbohydrate, sodium, iron and vitamin C) with BMI of students. There was significant association (p = 0.001) between dietary intake (calorie) and BMI. In conclusion, it is evidenced that the dietary intake of these students influences their BMI status, instead of the behaviour of skipping breakfast. The importance of having breakfast should be emphasised among the university students, the students should prioritise their daily nutrient intake by taking regular breakfast.
