Abstract
Purpose: The United States is typically viewed as a wealthy country, yet not all households have access to enough food for an active, healthy life. The purpose of this study was to validate a two-item written food security screen that health providers may use to identify food insecurity in their patient populations. Methods: Data were obtained from 150 parents or guardians who brought a child to a dental appointment at The Center for Pediatric Dentistry, University of Washington, Seattle, Wash., USA. The sensitivity and specificity of two written questions were determined by comparing with the United States Department of Agriculture Six-item Short Form of the Food Security Survey Module. Results: The sample consisted of 141 surveys after those with critical questions left blank were removed. The prevalence of food insecurity was found to be 31 percent at the Center for Pediatric Dentistry. The six-item screen identified 44 foodinsecure families with an affirmative response to two or more questions. Compared with the six-item screen, the two-item screen was found to have 95.4 percent sensitivity and 83.5 percent specificity.Conclusions: The two-item food security screen was found to be sensitive and reasonably specific, providing a quick and accurate method to identify food-insecure families.
