Abstract 1016: Food insecurity among patients with cancer in the US

Abstract Introduction: Food insecurity (FI) is common among cancer patients and can lead to decreased treatment adherence, worse quality of life, and increased recurrence and mortality. Although some studies suggest that patients with cancer are particularly susceptible to FI, these studies have been limited by their small sample size, narrow sampling of cancer types and stages, and limited geographic scope. To address this gap, this study leverages data from a supportive care organization to characterize FI prevalence and associated risk factors in a nationwide sample of patients with diverse types of cancer. Methods: This cross-sectional study included adults with cancer undergoing treatment referred to Family Reach, a national organization that provides financial support to cancer patients and their families, from 2020-2023. The primary outcome was FI, defined as a self-reported concern that the family would run out of food before getting enough money to buy more. Estimates of FI were provided for the cohort stratified by cancer type; multivariable logistic regression was used to evaluate the association of cancer type (primary independent variable) with FI, adjusted for oncologic and demographic covariates. Results: Of 6,615 patients with cancer, 62.9% reported FI. Across cancer types, FI prevalence ranged from 56% (brain) to 68% (gynecologic). FI did not vary significantly by cancer type on multivariable logistic regression adjusted for oncologic, geographic, and demographic factors (Table 1). A variety of demographic factors were associated with FI (Table 1). Table 1.

FI was common across all types of cancer and was associated primarily with demographic characteristics. These FI prevalence and risk factor data can be used by researchers, clinicians, and community-based organizations to understand and address FI among patients with cancer.
