The Effect Food Insecurity Has on Mental and Physical Health, and Sleep Quality Among College Students
Undergraduate students often face significant lifestyle shifts during their transition to university, including newfound autonomy and increased social and academic demands, which can lead to poor mental and physical health (Hagedorn et al., 2021). This period is frequently marked by high rates of sleep disruption and the emergence of food insecurity, defined as limited or uncertain access to safe and nutritious food, both of which are linked to decreased academic success and retention. Hagedorn and colleagues (2021) explored the associations between food insecurity, sleep quality, and the frequency of poor mental and physical health days among college students. The study, which used a cross-sectional design, analyzed data from a large sample of 17,686 students across twenty-two higher education institutions in the United States, finding that food-insecure students were significantly more likely to experience poor sleep quality and higher levels of psychological and physical distress than students who ate more nutritious foods.
To assess student well-being, researchers administered an online survey to 17,686 college students across twenty-two higher education institutions in the United States. Food security status was measured using the USDA's ten-item Adult Food Security Survey, modified to capture the timeframe since the students began college. Sleep quality was evaluated using the nineteen-item Pittsburgh Sleep Quality Index (PSQI), while mental and physical health were assessed through the Healthy Days Core Module, which tracks the number of days in the past month that health issues interfered with daily activities. Multivariate logistic regression was then used to determine the relationship between food security and these health outcomes, expressed as an Adjusted Odds Ratio (AOR).

Results indicated that 43.4% of participants were food insecure, and these students had significantly higher odds of experiencing poor sleep quality (AOR: 1.13), as well as more frequent days of poor physical and mental health (AOR: 1.01 and 1.03, respectively). Food-insecure students were also more likely to report that their health prevented them from completing daily tasks. Based on these findings, Hagedorn et al. (2021) concluded that food insecurity is a critical public health issue on campuses that requires multi-level policy changes and integrated wellness programming to improve student health and academic success.
These results are significant because they highlight how basic physiological needs, like nutrition and sleep, serve as the foundation for a student's mental and physical health. In the modern campus environment, the prevalence of convenient "fast-food" style dining plays a real role here. As a current student at Emory, I've seen this firsthand — a dining hall like Cox Hall can lead students to prioritize speed over substance, because grabbing quick fuel wins out over quality of food. These locations make it easy to get a meal during a hectic schedule, but they often lack the diverse nutrients students need for high-level cognitive function and restorative sleep.
This is part of what drives the so-called "freshman 15": once students stop paying attention to what they're eating and start grabbing whatever is in front of them just to keep moving through a long day, weight gain often follows. And when students rely on processed, nutrient-poor options, they may unintentionally worsen the very symptoms of food insecurity and poor sleep quality that this study describes.
Implementing university-wide wellness initiatives that go beyond simple food access — and focus on nutritional quality and sleep hygiene — is essential for student well-being. At a campus like Emory, this could look like integrating more "farm-to-table" options into central dining hubs that are still quick and always available, or offering subsidies for fresh produce at campus markets so they can compete with the convenience of fast food.
Students can also find their own ways to bridge these gaps: booking a nutritionist consultation at the campus health center to learn how to navigate dining halls more healthily, organizing meal-prep socials to split the cost and labor of cooking nutrient-dense meals, or using budget-tracking and wellness apps to find affordable groceries nearby. Ultimately, if universities prioritize the quality of students' "fuel" and environment, academic performance and overall life satisfaction are likely to follow — students who feel physically and mentally nourished are simply better equipped to handle the stresses of university life.
