It is unknown if participation in the Supplemental Nutrition Assistance Program (SNAP) influences the magnitude of improvement in dietary intake in response to dietary interventions. Adults with low socioeconomic status (SES) tend to have lower overall dietary quality as compared to those with higher SES. However, low SES adults are more likely to receive benefits from SNAP, which gives nutrition assistance to millions of eligible Americans. The objective of this investigation is to examine differences in dietary intake between 1) SNAP participants, 2) those eligible for SNAP but not receiving (nonparticipants), and 3) those ineligible for SNAP, in response to an intervention targeting a reduction in sugar-sweetened beverage (SSB) consumption. Adult participants (n=146) from Southwest Virginia were enrolled in a 6-month, community-based trial, SIPsmartER. Participants provided SNAP enrollment status and 3 24-hour dietary recalls at baseline and 6-months. Dietary variables (SSB, macronutrients, etc.) and dietary quality data (Healthy Eating Index [HEI-2010]) were derived from nutritional analysis software (NDS-R 2011). Statistical analyses included descriptives and repeated-measures ANOVA. Although SNAP participation and eligibility status did not impact the overall effectiveness of this dietary intervention, the within group data suggests that those eligible for SNAP but not participating (n=30) may be at a disadvantage to improving their dietary intake as compared to those at a similar household income who receive SNAP benefits (n=56) or ineligible individuals at a higher income level (n=60). Future research is needed to explore if participant's ability to maintain long-term adherence to the dietary changes differs between groups.
