Poor sleep is common amongst college students and is hypothesized to negatively impact academic performance. However, much of the work on this topic has been cross-sectional and has not accounted for fluid intelligence or baseline mental health, thereby limiting understanding of causal direction. First year college students (N=489, Mage=18.3; 72.2% female; 53.8% BIPOC) were recruited to complete a baseline assessment that included measures of sleep quality, social jetlag, chronotype, daytime sleepiness, mental health, and fluid intelligence. Sleep quality and social jetlag remained predictive of grade point average (GPA) after controlling for all variables (ps<.05). After excluding participants with very low GPAs (< 2.0), sleep quality but not social jetlag continued to predict future GPAs. Social jetlag was predictive of receiving a GPA <2.0, (OR=1.02). Poor sleep and social jetlag early in college are independent risk factors for lower future academic success.","abstract_html":"Sleep health is associated with health and academic outcomes.
