The Effect of Chronic Illness on Participation in the Supplemental Nutrition Assistance and Medicaid Programs
研究发现，身体差、有多种慢性病的成年人更可能同时参加SNAP和Medicaid，但单独参加SNAP的可能性更低；Medicaid扩张和协调政策有望增加SNAP中慢性病患者的人数。
We examine enrollment in the U.S. Medicaid and Supplemental Nutrition Assistance Programs (SNAP) and find that while SNAP‐eligible adults in poor physical health and with multiple chronic conditions are more likely to jointly enroll in SNAP and Medicaid, they are less likely to enroll in SNAP alone. We also find that the conditional probability of SNAP enrollment given Medicaid participation is higher for individuals with multiple chronic conditions. As a result, the expansion of Medicaid and state policies that promote enrollment coordination between SNAP and Medicaid are expected to increase the number of individuals in SNAP with chronic medical conditions.
