Background: Poor nutritional practices and heightened levels of stress, two common attributes of university life, are strongly linked with weight gain and decreased health. Little research has examined the relationships between university students' lifestyle factors and campus eating behaviours; therefore, this study aimed to examine relationships between lifestyle and campus eating behaviour. Methods: Both lifestyle and eating behaviour questionnaires were developed and administered to male and female undergraduate students at a Canadian university (n=132). Participants were asked to complete the questionnaire during allotted class time or return the completed questionnaire at the following lecture. Data was analysed with a combination of correlation and difference testing. Results: Students whose living arrangements had not changed since high school consumed less alcohol than individuals who moved away from their previous dwellings. Fast food consumption was also significantly related to lower physical activity levels and higher expenditures for food on campus. Males also consumed more alcohol than females and spent more money for food on campus. Conclusion: Relationships do exist between lifestyle and campus eating behaviour. These results may be used as a foundation for future research on the effect of lifestyle on eating behaviours and nutritional status in university age students. (Contains 3 tables.)
