Introduction. The Supplemental Nutrition Assistance Program – Education (SNAP-Ed) is the largest federal program designed to promote healthy eating among low-income Americans. In California, the SNAP-Ed goals include improving dietary quality, increasing fruit and vegetable consumption and reducing added sugar intake. This study examines trends in nutritional quality and consumption of targeted foods among SNAP-eligible subgroups in California. Methods. Representative cross-sectional samples of low-income Californians (mother/child pairs) were collected by telephone survey between 2014 and 2017. The Automated Self-administered 24 hour Recall (ASA24) captured dietary behaviors. Race/ethnicity, highest level of education, and age were also recorded. Three dietary outcome variables were derived from the ASA24 data: (1) cups of fruits and vegetables; (2) cups of sugar-sweetened beverages (SSBs); and (3) HEI-2015 scores. Generalized estimating equations, accounting for correlation within pairs, were used to model differences among yearly samples. Results. A total of 21,032 surveys were collected during the study period. No overall improvements in dietary quality, FV or SSB consumption were observed for the entire sample, however some subgroups did show improvements. Significant increases in HEI and fruit and vegetable intake, and reductions in SSB intake were observed among some population subgroups, while other groups did not see change. Discussion. The results suggest that improvements in diet and nutrition may be occurring over time in some low-income California populations, but not in others. This may have important programmatic implications in terms of efforts to effectively deliver SNAP-Ed to all segments of California’s diverse population.
