Navigating Hidden Hunger: An Exploratory Analysis of the Lived Experience of Food Insecurity among College Students

Translational science approaches for food insecurity research

Food insecurity is a pervasive problem that impacts health and well-being across the lifespan. The human research linking food insecurity to poor metabolic and behavioral health outcomes is inherently correlational and suffers from a high degree of variability both between households and even within the same household over time. Further, food insecurity is impacted by societal and political factors that are largely out of the control of individuals, which narrows the range of intervention strategies. Animal models of food insecurity are being developed to address some of the barriers to mechanistic research. However, animal models are limited in their ability to consider some of the more complex societal elements of the human condition. We believe that understanding the role that food insecurity plays in ingestive behavior and chronic disease requires a truly translational approach, and that understanding the health impacts of this complex social phenomenon requires understanding both its psychological and physiological dimensions. This brief review will outline some key features of food insecurity, highlighting those that are amenable to investigation with controlled animal models and identifying areas where integrating animal and human studies can improve our understanding of the psychological burden and health impacts of food insecurity. In the interest of brevity, this review will largely focus on food insecurity in the United States, as the factors that contribute to food insecurity vary considerably across the globe.

Associations Between Food Insecurity and Diet Quality Among Graduate Students and Postdoctoral Trainees in the Health Sciences at a Private University in Boston: A Cross-Sectional Study

Background

Food insecurity is a pivotal determinant of health outcomes. Little evidence exists on the association between food insecurity and health behaviors and outcomes, including diet quality, among graduate students or postdoctoral trainees.

Objectives

This study aimed to examine the association between food insecurity and diet quality among graduate students and postdoctoral trainees at 3 health-focused graduate schools (public health, medical, and dental medicine) within Harvard University.

Methods

Between April and June 2023, 1287 graduate students and 458 postdoctoral trainees at the health-focused schools within Harvard University completed a web-based survey. The primary exposure was food security status, assessed using the United States Household Food Security Survey Module. The primary outcome was diet quality, measured using the 30-day Prime Diet Quality Score screener (ranges from 0 to 126, with higher scores indicating healthier diets). The associations between food insecurity and diet quality were examined using multivariable regression models, adjusting for sociodemographic covariates.

Results

Among graduate students, compared with those with high food security, diet quality was significantly lower among those experiencing marginal food security [β: -4.7; 95% confidence interval (CI): -6.5, -2.9], low food security (β: -5.4; 95% CI: -7.6, -3.3), and very low food security (β: -4.4; 95% CI: -7.4, -1.4). Poor diet quality included lower intake frequencies of vegetables, fruits, beans/peas/soy products, nuts/seeds, poultry, fish, low-fat dairy, and liquid oils, and higher intake frequencies of refined grains/baked products, sugar-sweetened beverages, and fried foods. Among postdoctoral trainees, compared with those with high food security, diet quality was significantly lower among those experiencing low food security (β: -5.1; 95% CI: -8.8, -1.4), and very low food security (β: -5.2; 95% CI: -10.2, -0.2). Poor diet quality included lower intake frequencies of dark green leafy vegetables, other fruits, and whole grains.

Conclusions

Graduate students and postdoctoral trainees who experienced degrees of food insecurity reported lower diet quality. These observations underscore the need for policies and interventions to simultaneously reduce food insecurity and improve diet quality.

Associations between health issues and food consumption with overweight and obesity in three university students minorities

Objective: To determine the presence of overweight and obesity among minorities, and the factors contributing to this weight disparity. Participants: The study comprises 3405 students including nonwhite, international, and first-generation college students. Methods: An online cross-sectional survey collected data on demographics, height, weight, self-health perception, overall sleep quality, progress in school, and food consumption. Three logistic regressions tested abnormal weight associations with health issues and food consumption. Results: Being 31 years-old or older, perception of health and consumption of ultra-processed food was significant with abnormal weight (BMI > 25). Only nonwhite and international students were correlated with ultra-processed and fast-food consumption respectively. Conclusion: Each minority presented vulnerabilities to high percentages of weights exceeding the appropriate rates of BMI. The high consumption of fast and ultra-processed foods makes it important to consider factors related to health perception in each minority group.

Food Insecurity in Higher Education: A Contemporary Review of Impacts and Explorations of Solutions

Food insecurity is a global phenomenon which impacts a variety of social, economic, and life-stage groups. One such group affected by food insecurity is college students, who tend to experience food insecurity at a prevalence which exceeds the average of their local communities. The impacts of food insecurity in this population are multifaceted and have implications for their college experience and beyond. Food insecurity has been observed to have negative effects on college student academic performance, physical health, and mental health. This review explores the impacts of and solutions for food insecurity in this population globally, with particular emphasis on the United States, and specifically California.
