The impact of the Supplemental Nutrition Assistance Program on the cardiovascular health of low-income adults
This project investigates how participation in the Supplemental Nutrition Assistance Program (SNAP), and related state-level policies, influence cardiovascular health among low-income adults in the United States. Although SNAP has been linked to improved food security and reduced healthcare spending, its impact on cardiovascular outcomes remains unclear. Using nationally representative survey data linked with Medicare and Medicaid claims, Dr. Khatana’s research will assess whether SNAP participation improves medication adherence, reduces psychosocial stress, and lowers healthcare utilization among individuals with cardiovascular disease. Additional analyses will examine how variation in state SNAP policies and benefit amounts affect rates of acute cardiovascular events. This work will inform policy decisions on the broader health impacts of food assistance programs.
Association of Health Insurance with Access to Cardiovascular Care
Dr. Khatana’s research explores how health insurance coverage impacts cardiovascular care and outcomes among low-income and racially minoritized populations. Building on prior work showing that Medicaid expansion was associated with reduced cardiovascular mortality, his current research investigates whether insurance expansion improves access to inpatient and outpatient cardiovascular care and reduces racial disparities in access. The study uses large administrative claims data and qualitative interviews with low-income patients recently hospitalized for cardiovascular events to understand the role of insurance in shaping post-discharge experiences and outcomes. This work supports Dr. Khatana’s broader goal of advancing health policy research that improves cardiovascular outcomes in underserved populations.
