Abstract

Food insecurity is a major public health concern among university students. This cross-sectional study examined factors associated with food insecurity during and after the COVID-19 pandemic among 1864 students (mean age: 20.6 ± 2.9 years) from selected public universities in Northwest Mexico. Data were collected in two cross-sectional survey waves: during the COVID-19 pandemic (n = 1188) and after the pandemic (n = 676). Data were collected through online surveys during the pandemic and face-to-face interviews in the post-pandemic period. Food insecurity was assessed using the Food Insecurity Experience Scale (FIES). Multiple linear regression models were used to identify factors associated with food insecurity and to examine its association with body mass index, perceived stress, sleep quality, and academic performance. Overall, 62.2% of students experienced food insecurity. Food insecurity was higher among students surveyed after the COVID-19 pandemic than among those surveyed during the pandemic (73.7% vs. 55.7%, p < 0.001). During the pandemic, higher food insecurity scores were associated with older age, female sex, indigenous self-identification, living alone, academic discipline, study hours, educational financing, and poorer nutritional behaviors. In the post-pandemic period, indigenous self-identification, living arrangements, academic discipline, and poor nutritional behaviors remained associated with food insecurity. In both periods, food insecurity was associated with higher perceived stress, poorer sleep quality, and lower academic performance (p < 0.05). These findings suggest that food insecurity remains a major concern among university students and indicate the importance of developing culturally appropriate strategies to support vulnerable student populations.
