Abstract
OBJECTIVES: We examined whether Supplemental Nutrition Assistance Program (SNAP) participation changes associations between food insecurity, dietary quality, and weight among US adults. METHODS: We analyzed adult dietary intake data (n = 8333) from the 2003 to 2010 National Health and Nutrition Examination Survey. Bivariate and multivariable methods assessed associations of SNAP participation and 4 levels of food security with diet and weight. Measures of dietary quality were the Healthy Eating Index 2010, total caloric intake, empty calories, and solid fat; weight measures were body mass index (BMI), overweight, and obesity. RESULTS: SNAP participants with marginal food security had lower BMI (1.83 kg/m2; P < .01) and lower probability of obesity (9 percentage points; P < .05). SNAP participants with marginal (3.46 points; P < .01), low (1.98 points; P < .05), and very low (3.84 points; P < .01) food security had better diets, as illustrated by the Healthy Eating Index. Associations between SNAP participation and improved diet and weight were stronger among Whites than Blacks and Hispanics. CONCLUSIONS: Our research highlights the role of SNAP in helping individuals who are at risk for food insecurity to obtain a healthier diet and better weight status.
