To examine the effect of food insecurity during college on graduation and degree attainment.

Secondary analysis of longitudinal panel data. We measured food insecurity concurrent with college enrolment using the 18-question United States Department of Agriculture Household Food Security Survey Module. Educational attainment was measured in 2015–2017 via two questions about college completion and highest degree attained. Logistic and multinomial logit models adjusted for socio-demographic characteristics were estimated.

USA

A nationally representative, balanced panel of 1574 college students in the USA in 1999–2003 with follow-up through 2015–2017 from the Panel Study of Income Dynamics.

In 1999–2003, 14·5 % of college students were food-insecure and were more likely to be older, non-White and first-generation students. In adjusted models, food insecurity was associated with lower odds of college graduation (OR 0·57, 95 % CI: 0·37, 0·88, P = 0·01) and lower likelihood of obtaining a bachelor’s degree (relative risk ratio (RRR) 0·57 95 % CI: 0·35, 0·92, P = 0·02) or graduate/professional degree (RRR 0·39, 95 % CI: 0·17, 0·86, P = 0·022). These associations were more pronounced among first-generation students. And 47·2 % of first-generation students who experienced food insecurity graduated from college; food-insecure first-generation students were less likely to graduate compared to first-generation students who were food-secure (47·2 % v. 59·3 %, P = 0·020) and non-first-generation students who were food-insecure (47·2 % v. 65·2 %, P = 0·037).

Food insecurity during college is a barrier to graduation and higher-degree attainment, particularly for first-generation students. Existing policies and programmes that help mitigate food insecurity should be expanded and more accessible to the college student population.
