Investigate the relationship between intensities of physical activity and severity of drunkorexia behaviors. First-year college students living in residence halls ( = 127) completed an online survey comprising drinking, drunkorexia, and physical activity. Multiple hierarchical linear regressions were implemented to examine if physical activity intensity correlates to drunkorexia severity. Vigorous physical activity was the only physical activity intensity significantly associated with severity of drunkorexia behaviors. First-year college students' duration of vigorous physical activity in relation to severity of drunkorexia behaviors may vary contingently on the motivation for vigorous physical activity. Practitioners need to consider physical activity can be a co-occurring risk behavior in combination with alcohol misuse.
