Abstract

Objective: To examine associations between lifestyle choices and academic performance, considering differences by gender and the potential influence of psychopathology. Participants: 1,447 first-year Canadian undergraduates. Methods: Exposures from the Fall 2021 U-Flourish survey included substance...
