The food environment and hypertension: A cross-sectional analysis in Black breast cancer survivors in Maryland.

OBJECTIVES

The Food Environment Index (FEI) has shown varying positive impacts on health outcomes related to diabetes, obesity, and hypertension. However, a relationship between FEI and hypertension among breast cancer (BC) survivors, particularly Black women survivors, remains underexplored. Black women who are BC survivors have a high prevalence of hypertension and increased risk of mortality compared to White women with BC. Our analysis aims to fill this gap by assessing the FEI's association with hypertension in this population.

DESIGN

Utilizing social media recruitment strategies and BC survivor networks, 100 Black female BC survivors completed an online survey, that included sociodemographic and clinical characteristics as well as lifestyle factors. The 2023 FEI County Health Rankings was used to assess the food environment and the index ranges from 0 (worst) to 10 (best). Adjusted prevalence odds ratios (PORs) and 95 % confidence intervals (CI) were calculated for the associations between FEI, sociodemographic and clinical factors, and hypertension status.

RESULTS

Among the 94 study participants with data on hypertension status, 54.3 % reported a diagnosis of hypertension. Residing in counties with a below-median FEI (<8.8 v. above median: ≥8.8) was significantly associated with hypertension (POR = 4.10, 95 % CI: 1.19-14.13). Age at survey (≥50 years compared to <50 years: POR= 0.29, 95 % CI: 0.10-0.87) and household income ($75,000-$99,999 compared to > $99,999/year: POR = 12.02, 95 % CI: 2.08-69.43) were also significantly associated with hypertension.

CONCLUSION

Our study highlights the potential impact of the food environment on hypertension among Black BC survivors living in Maryland. Our findings call attention to the need for targeted interventions to improve food accessibility and quality in underserved communities, especially for special populations such as cancer survivors.
