SNAP Participation Moderates the Association Between Household Food Insecurity and A1c Among Cambodian Americans With Depression
Abstract Objectives We tested whether participation in the Supplemental Nutrition Assistance Program (SNAP) moderated the relation between household food security status and HbA1c, the gold standard measure of glycemic control, among Cambodian Americans with depression enrolled in a diabetes prevention trial. Methods Participants had elevated risk factors for type 2 diabetes and elevated depressive symptoms; recruits were excluded for extant diabetes. Community health workers assessed household food security status and SNAP participation via in-person interview. HbA1c levels from venous blood samples were ascertained using direct enzymatic assay. Results Among respondents (n = 189), 19% were food insecure, 41% received SNAP benefits, and mean HbA1c = 5.5%. There was a significant interaction between SNAP and food insecurity. HbA1c was highest among participants without SNAP who were food insecure. Simple effects analysis revealed a significant difference within the no SNAP group [Mean (SD) HbA1c: Secure = 5.38 (0.38), Insecure = 5.78 (0.36)] and no difference within the SNAP group [Secure = 5.61(0.44), Insecure = 5.61(0.55)]. Differences remained significant after controlling for demographic, socioeconomic, and clinical indicators. Conclusions SNAP may protect against the deleterious association between household food insecurity and elevated HbA1c. Funding Sources R01-DK103663 to Dr. Julie Wagner.
