Introduction. Effective communication approaches are necessary to reach food-security program participants. Accessing food-security programs has been especially challenging during the COVID-19 pandemic. Social media can play an important role in reducing some communication barriers. We examined interest in receiving nutrition information via social media among adults participating in food-security programs in Washington, DC. Methods. We developed and administered a 22-item survey to adults participating in food-security programs (N=375). Participants were recruited at Martha's Table, in Washington, DC, from January through March 2020. We performed bivariate analyses and multinomial logistic regressions to examine predictors of interest in receiving nutrition information via social media. Results. Sixty-nine percent of participants reported using social media, and 49% expressed interest in receiving nutrition information via social media. Higher levels of self-efficacy and belief in the value of digital technology were associated with greater likelihood of interest in receiving nutrition information via social media (χ26= 139.0; Nagelkerke R2= 0.35; P<.001). We found no differences by sex or digital technology access in interest in receiving nutrition information via social media. Conclusion. Social media is a widely used and a feasible method to reach food-security program participants. Understanding program participants" interest in receiving health information via social media may help food-security programs plan effective communication strategies to improve food security, especially when in-person participation is limited, such as during the COVID-19 pandemic.
