Scope and social determinants of food insecurity among adults with atherosclerotic cardiovascular disease in the United States

BACKGROUND: Atherosclerotic cardiovascular disease (ASCVD) results in high out-of-pocket healthcare expenditures predis-posing to food insecurity. However, the burden and determinants of food insecurity in this population are unknown. METHODS AND RESULTS: Using 2013 to 2018 National Health Interview Survey data, we evaluated the prevalence and so-ciodemographic determinants of food insecurity among adults with ASCVD in the United States. ASCVD was defined as self-reported diagnosis of coronary heart disease or stroke. Food security was measured using the 10-item US Adult Food Security Survey Module. Of the 190 113 study participants aged 18 years or older, 18 442 (adjusted prevalence 8.2%) had ASCVD, representing ≈20 million US adults annually. Among adults with ASCVD, 2968 or 14.6% (weighted ≈2.9 million US adults annually) reported food insecurity compared with 9.1% among those without ASCVD (P<0.001). Individuals with ASCVD who were younger (odds ratio [OR], 4.0 [95% CI, 2.8–5.8]), women (OR, 1.2 [1.0–1.3]), non-Hispanic Black (OR, 2.3 [1.9–2.8]), or Hispanic (OR, 1.6 [1.2–2.0]), had private (OR, 1.8 [1.4–2.3]) or no insurance (OR, 2.3 [1.7–3.1]), were divorced/widowed/sepa-rated (OR, 1.2 [1.0–1.4]), and had low family income (OR, 4.7 [4.0–5.6]) were more likely to be food insecure. Among those with ASCVD and 6 of these high-risk characteristics, 53.7% reported food insecurity and they had 36-times (OR, 36.2 [22.6–57.9]) higher odds of being food insecure compared with those with ≤1 high-risk characteristic. CONCLUSION: About 1 in 7 US adults with ASCVD experience food insecurity, with more than 1 in 2 adults reporting food insecurity among the most vulnerable sociodemographic subgroups. There is an urgent need to address the barriers related to food security in this population.
