Background Vigorous physical activity (VPA) may be beneficial for mental health. The aim of the study was to investigate cross-sectional associations between VPA, perceived stress, sleep quality and quantity and mental health among university students. Methods In a cross-sectional study, using anonymous questionnaires, data was collected from 15122 (42.1% male and 57.9% female) university students [mean age 20.6, standard deviation (SD) = 2.0] from 23 countries in the Americas, Africa and Asia. They were assessed using the International Physical Activity Questionnaire (short version), and measures of sociodemographic, health status, health behaviour and anthropometrics. Results Students who met VPA recommendations were less likely to report perceived stress, more likely to report subjective good health and depression than students without VPA. There was no association between VPA and sleep quality and quantity and PTSD symptoms. Conclusion This study only found partial benefits of VPA in relation to well-being of university students.
