Association of food insecurity with overall and disease-specific mortality among cancer survivors in the US

To investigate the association of food insecurity with overall and disease-specific mortality among US cancer survivors. Data from the National Health and Nutrition Examination Survey (NHANES 1999–2018) were used to examine the impact of food insecurity on mortality risks among cancer survivors in the US.
