The Potential Impact of Food Insecurity in an Urban Trauma Population

Food insecurity (FI) has been defined as a lack of consistent access to enough food for a healthy active lifestyle. As of 12.7% of the United States are suffering from FI, which has been correlated with increased hospital costs and poorer health outcomes. Currently, limited data exists examining the relationship between trauma populations and FI despite both having similar root causes. We sought to determine this and validate a screening tool for FI in this population.

A cross-sectional survey study of trauma patients was conducted at a level 1 trauma center in Atlanta, Georgia. Survey questions included the first two items of the Core Food Security Module. Zip codes were used to determine FI, defined by the USDA Food Access Research and compared to individual participant survey responses. Binary classification test metrics were calculated to validate the two items as a screening tool in this population.

The cohort included 136 patients, of which the majority were black (60.3%) and male (60.3%). Thirty-one respondents affirmed food security (22.8%) despite over half (51.5%) living in a food insecure community. The sensitivity and specificity for this screening to predict FI were 25 and 80%, respectively.

Although the specificity is high, this screening tool has a low sensitivity, accuracy, NPV, and PPV to determine food insecurity in this population. Community-level statistics suggests that food insecurity is a significant public problem amongst trauma patients. Prevention efforts should, therefore, aim to address both issues simultaneously.
