RESUMO
BACKGROUND: Food insecurity, lack of access to sufficient food for an active, healthy life, is a persistent problem in the United States. Recently, nutrition security has emerged as a new concept. However, limited research exists examining how nutrition security relates to the established concept of food security. OBJECTIVES: This study assessed a recent metric of nutrition security and explored how well it describes the underlying construct among a sample of Supplemental Nutrition Assistance Program (SNAP) participants. We examined the correlation between food and nutrition security and demographic predictors of joint food and nutrition security status. METHODS: We conducted a national, web-based survey (Qualtrics; 30 September-19 October, 2022) in English and Spanish of adults aged ≥18 y (n = 1454) who reported receiving SNAP benefits in the past 12 mo. We measured food security using the US Department of Agriculture 6-item Food Security Survey and assessed nutrition security using the Gretchen Swanson Center for Nutrition Household Nutrition Security measure. We used multinominal logistic regression to examine demographic predictors of food and nutrition security. RESULTS: The majority (80.4%) of SNAP participants experienced food insecurity, and 59.1% reported experiencing nutrition insecurity. Food and nutrition security were moderately correlated (0.41); 55.6% of SNAP participants were both food and nutrition insecure, 3.5% were food secure but nutrition insecure, 24.8% were food insecure but nutrition secure, and 16.1% were both food and nutrition secure. Of SNAP participants, 24.8% reported experiencing food insecurity but not nutrition insecurity. Hispanic ethnicity and Southern residence were associated with joint food and nutrition insecurity. CONCLUSIONS: These findings raise questions about how nutrition security is conceptualized and measured and its added value beyond existing food security measurement scales. Further research is needed to understand differences in food and nutrition security experiences and risk factors and determine a validated definition and measure of nutrition security for future policy solutions.
