US postsecondary students' health and academic outcomes: A comprehensive scoping review

Objective: The relationship between postsecondary students' health and academic outcomes may have important implications for their collegiate experience and their future prospects. Yet a comprehensive summary of the evidence examining this potential connection does not presently exist. Seeking to fill this gap, this study reviewed the extant literature on postsecondary students' academic outcomes and health across multiple domains. Methods: Using an established methodological framework, a scoping review was conducted to identify and summarize the attributes of all peer-reviewed research performed in the U.S. and published between 2008 and 2019 that examined the relationship between postsecondary students' health and academic outcomes. Results: The search strategy resulted in 12,488 articles. After deduplication, initial screening, and full review of relevant articles to determine eligibility, 264 articles were included in the final review. The most frequently examined health domains were mental health and substance use. Grade point average (GPA) was the most common academic measure investigated. Most studies took place at single institutions among undergraduate students, and several studies focused on specific student sub-populations. Almost all study results indicated that healthier behavior or optimal health status was associated with better academic outcomes or did not negatively impact academic success. Conclusions: This study serves as a first step in understanding the scope of existing research examining the connection between postsecondary students' health and academic outcomes. A substantial literature base was found; however, several gaps were identified including the need for more cohort studies, national studies, examination of graduate students, and a focus on academic outcomes beyond GPA.
