Background: Food deserts (FD), low-income areas with low-access to healthful foods, are associated with higher burden of CV risk factors. We sought to determine if living in a FD is associated with worse clinical outcomes in heart failure (HF) patients.
Methods: HF patients (N=227, mean age 57 ± 12 yrs, black race= 42%, male= 63%) were prospectively enrolled from 2007 to 2010. FD status was assessed using the FD Research Atlas. Kaplan Meier analysis and Cox proportional hazards regression were used to determine the association of FD with the composite primary endpoint (PE) of death and hospitalization at 1 year.
Results: Patients who lived in a FD (N=36) were younger (P=0.045), more likely to be Black (P<0.001), and more likely to have a high school education or less (P=0.008). During a median follow-up of 421 (IQR 145, 1018) days, the PE occurred in 176 (77.5%) subjects. The risk of the PE differed by race and FD status (Figure 1, P=0.09 for interaction). After adjustment for age, gender, and education, Whites who lived in a FD (HR=2.3, 95% CI 0.9-5.5; P=0.06) had a higher risk for the PE compared to Whites who did not live in a FD (reference). Blacks had a higher risk for the PE regardless of whether they lived in a FD (HR=1.7, 95% CI 0.9-3.1; P=0.09) or not (HR= 1.8, 95% CI 1.2-2.8; P=0.009).
Conclusions: Blacks had the highest risk of the PE regardless of FD status, while Whites who lived in a FD had a higher risk than Whites who did not live in a FD.
