Food insecurity, psychosocial health and academic performance among college and university students in Georgia, USA

Abstract

AbstractObjectiveTo examine whether psychosocial health mediates the association between food insecurity and grade point average (GPA) among college and university students.DesignData for the present study are from a longitudinal cohort study. Structural equation modelling (SEM) was used to test the proposed mediation hypothesis. Food insecurity was measured using the US Department of Agriculture’s Six-Item Short Form. Psychosocial health was operationalized as a latent factor with three indicators: depression, anxiety and hope. Validated scales were used to measure each indicator. GPA was self-reported.SettingSeven colleges and universities in Georgia, USA.ParticipantsStudents aged 18–25 years were recruited via email and surveyed every four months over a two-year period (analytic n 2377).ResultsApproximately 29 % of students were food insecure. In the final SEM, food insecurity was associated (standardized β, se) with poorer psychosocial health (0·22, 0·03, P<0·0001) and poorer psychosocial health was associated with a lower GPA (−0·21, 0·03, P<0·0001). The indirect effect of food security status on GPA, as mediated by psychosocial health, was significant (−0·05, 0·01, P<0·0001) and accounted for 73 % of the total effect. After accounting for psychosocial health, the direct effect of food security status on GPA was not significant (−0·02, 0·02, P=0·43).ConclusionsPsychosocial health may be an important mechanism through which food insecurity affects academic performance among college and university students. Multicomponent interventions that address immediate food security needs as well as co-occurring mental health and academic concerns are needed to ensure student success.
