This study aimed to assess overweight and obesity and associated factors in school-going adolescents in Brunei Darussalam. The sample included 2599 school-going adolescents that responded to the Global School-based Student Health Survey (mean age 14.7 years, SD = 1.4). Body weight status was assessed based on self-reported height and weight and the international child body mass index standards. The relationship between lifestyle factors, including physical activity and dietary behaviour, and overweight or obesity were assessed using logistic regression analyses. Results indicate a prevalence of overweight or obesity of 35.1% and obesity of 17.3%. In multivariable regression analysis, bullying victimisation was positively and frequent fast food consumption, having experienced hunger and meeting physical activity recommendations were negatively associated with overweight or obesity. High prevalence rates of overweight or obesity were found and several risk factors identified, which can assist in guiding interventions.Mahidol UniversityMedicineSCOPUS10.1515/ijamh-2018-0019
