a dissertation Brady et al. (2023) Designed to measure this relationship in the United States. They use 1997-2019 Panel Study of Income Dynamics (PSID) data combined with cross-country equivalent documents. Data were validated using information from the National Death Index. The authors adjusted for self-reported health status, demographic data, comorbidities, and various other factors. They found:
Current poverty was associated with a 1.42 (95% CI, 1.26-1.60) higher risk of mortality. Cumulative poverty—being consistently poor versus never being poor over the past 10 years—was associated with a 1.71 (95% CI, 1.45-2.02) higher risk of mortality.
This is a significantly higher risk factor for mortality compared with many common comorbidities.
