Abstract
Objectives
Tertiary education students have been found to experience a higher prevalence of food insecurity than the general population. This systematic review aims to examine the existing evidence on the association between food insecurity and dietary outcomes among higher education students.
Methods
Nine electronic databases and gray literature were searched. Studies that reported dietary outcomes (e.g., nutritional intake and meal patterns) in students of differing food security status in tertiary education settings in any country were included. All primary study designs were eligible for inclusion, except for qualitative studies. Two reviewers completed the title/abstract and full-text screening, data extraction, and quality assessment independently.
Results
A total of 14 studies were included in the final qualitative synthesis of this review. The prevalence of food insecurity among higher education students ranged from 21% to 82% across the included studies from the United States, Canada, Australia and Greece. Lower intakes of healthy foods (e.g., fruits, vegetables, and whole grains) and higher intakes of unhealthy foods (e.g., fast foods, added sugars, and sugar-sweetened beverages) were observed in food-insecure students. Some students also consumed less breakfast and evening meal than food-secure students but the evidence was limited. The overall diet quality was not consistently measured in students with different food security status by using validated dietary assessment tools.
Conclusions
Poorer dietary outcomes were found in higher education students with food insecurity compared with food-secure students. More policy interventions, effective nutrition education, and food assistance programs should be provided by tertiary education institutions and governments to target the nutritional needs of food-insecure students.
