Background: The coronavirus disease discovered in 2019 (COVID-19) has impacted the health behaviour of university students in a range of western nations and had a number of detrimental effects on their mental wellbeing. However, little is known about the impact on university students in Southeast Asia, particularly in Brunei. This study aims to estimate the prevalence and factors related to poor mental wellbeing and engaging in health-risk behaviors among university students in Brunei during the COVID-19 pandemic. Methods: A cross-sectional online survey of students in all public universities was conducted from March to June 2021. Warwick-Edinburgh Mental Well-being Scale, Global Physical Activity Questionnaire, and WHO STEPs questionnaires were used to measure mental wellbeing, physical activity, and health behaviors, respectively. Logistic regressions were applied. Results: A total of 1020 university students participated in this study (57% response rate). Prevalence of poor mental wellbeing and physical inactivity were 30% and 42.8%, respectively. Excessive snacking (89.7%), sugar intake (81.7%), and salt intake (53.8%) were the most prevalent health-risk behaviors. Body mass index and participating in sports activities were the most common factors related to mental wellbeing and health-risk behaviors. Conclusions: Participating in certain sports activities appears to have protective effects against study outcomes. However, a high prevalence of physical inactivity and unhealthy diet among university students is a concern, as it could be indicative of future non-communicable disease trends.
