ObjectivesFood insecurity is adversely associated with physical and mental health and wellbeing in children. The mechanism that underlies this association is assumed to be dietary intake; however, evidence linking food insecurity to child dietary intake has been mixed. This study examined the relationship between self-reported food insecurity and dietary intake among low-income 7–12 year old children. MethodsCross-sectional data were used from TX Sprouts, a school-based cooking, gardening, and nutrition intervention in 16 central Texas schools. A sample of 680 children completed two 24-hour dietary recalls (24hDR) and a questionnaire that included an adapted version of the 5-item Child Food Security Assessment (CFSA). Four ordinal groups, High Food Security (HFS), Marginal Food Security (MFS), Low Food Security (LFS), and Very Low Food Security (VLFS), were generated based on summed scores from the CFSA. The Health Eating Index-2015 and dietary components (total energy, macronutrients, and servings of fruits, vegetables, whole grains, and sugar-sweetened beverages (SSBs)) were derived from 24hDR. Multivariate linear regression models were used to examine the associations between food security and dietary outcomes. A priori covariates included sex, age, ethnicity, and daily energy. ResultsChildren in the study were 45% male, 54% Hispanic, and had an average age of 9.3 years. Main effects of food security were significant for added sugar (P < 0.03) and SSBs (P < 0.04). Compared to children with HFS (referent), those who were LFS and VLFS consumed more added sugar (33.2 g vs. 39.9 g and 40.6 g, P < 0.03 and P < 0.003; respectively). Compared to the HFS referent group, those who were MFS and VLFS had higher mean intakes of SSBs (0.6 vs. 0.8 and 0.9 servings, P < 0.03 and P < 0.01; respectively). There were no significant associations between food security and other dietary outcomes. ConclusionsSelf-reported food insecurity among children (7–12 years of age) was associated with higher added sugar and SSB intake. Future research should assess if the positive association between food insecurity and added sugar and SSB intake contributes to adverse health outcomes.
