DOWNLOAD EBOOKSNAP provides food-purchasing assistance for low-income Americans to alleviate hunger and improve nutrition. However, little is known about how SNAP benefits affect the household's food purchasing practices (FPP), diet quality, and food insecurity especially among low-income older adults whose SNAP participation has been typically lower than younger age groups. The goal of this study is to better understand the changes in FPP, diet quality, and food insecurity with the receipt of SNAP benefits among SNAP-eligible non-participating older adults in Georgia. A longitudinal mixed-methods approach was employed based on a natural experiment following a sample of low-income older Georgians (n=10) as they navigated the SNAP application process. An established SNAP application assistance model was utilized to help the study participants. The impact of SNAP benefit receipt was assessed using in-person interviews, interviewer-administered surveys, grocery receipt collection, and grocery shopping trip observations at three time points: 1) before SNAP benefit receipt, 2) one month after SNAP benefit receipt, and 3) three months after SNAP benefit receipt. Both qualitative and quantitative exploratory data analyses were conducted. At baseline, SNAP-eligible participants reported higher financial constraints, poorer food insecurity, but comparable diet quality in comparison to the general older adult population. The impact of SNAP participation was evident in increasing shifts in household expenditure patterns for food purchased for consumption and improved food security at midpoint. There were notable changes in six FPP constructs and related distinct practices following SNAP benefit receipt such as changes in the types of food purchased and the strategies employed in their purchase. Overall diet quality was not significantly improved after three months of SNAP benefit receipt, but there were significant increases in the intake quality of select nutrients of concern including saturated fat and sodium. The findings of this study provide a more in-depth conceptual understanding of the underlying mechanism of how SNAP benefits affect food and nutrition-related decision-making processes and behavior changes. These findings also support the feasibility of key strategies used in targeting and recruiting low-income older adults for SNAP research and the value of SNAP application assistance in evaluating the impact of SNAP participation.
