Abstract PO1-10-03: Prevalence of and Factors Associated with Food Insecurity and Other Adverse Social Determinants of Health Among Breast Oncology Patients

Abstract Background: Social determinants of health (SDOH), the non-medical factors that influence health status, have a profound impact on breast cancer (BC) outcomes and contribute to survival disparities. Food insecurity (FI), defined as a lack of consistent access to adequate food resources, is a modifiable SDOH associated with treatment disruptions, medication nonadherence, and decreased quality of life. To identify at-risk patients and inform future interventions, we implemented SDOH screening of patients seen in breast oncology clinic at our urban academic medical center. Methods: Screening was conducted through an 8-item questionnaire on the electronic patient portal. The questions covered FI, housing and transportation challenges, and emergency department (ED) visits. We conducted a retrospective analysis of SDOH data collected among patients scheduled for a breast oncology appointment between 11/1/22 and 5/25/23. Any level of food hardship or concern constituted a positive FI screen. Descriptive statistics were used to determine the prevalence of FI and other SDOH, to assess differences in FI rates by age, race/ethnicity, and clinical stage, and to compare characteristics of food-insecure vs food-secure patients. We also conducted a multivariable logistic regression analysis to estimate the odds ratio (OR) and 95% confidence interval (CI) associated with sociodemographic/clinical factors and FI. Results: A total of 2,585 patients were seen in our breast oncology practice, of which 1,189 (46.0%) were screened for SDOH, including 41.2% non-Hispanic White (NHW), 9.6% non-Hispanic Black (NHB) and 21.0% Hispanic patients. Among patients who responded to each SDOH question, 15.5% (146/940) reported some level of FI; 8.7% (84/962) were unable to pay their rent or mortgage on time; for 5.8% (57/989), lack of transportation interfered with their treatment. The FI rate differed significantly by race and ethnicity: 4.5% of NHW, 15.2% of NHB, and 41.8% of Hispanic patients reported FI (p 0.001). In multivariable analysis, NHB and Hispanic patients also had significantly higher odds of FI compared to NHW patients (OR=3.68, 95% CI=1.7-7.7, p 0.001 for NHB and OR=15.0, 95% CI=8.8-27.1, p 0.001 for Hispanic patients). Patients with metastatic disease had higher rates of FI compared to other breast oncology patients (23.6% vs 14.8%, p=0.048), and a metastatic BC diagnosis was associated with over twice the odds of FI (OR=2.18, 95% CI=1.1-4.2, p=0.02). Among food-insecure patients, 41.1% were unable to pay their rent or mortgage on time and 22.6% reported transportation difficulties interfering with treatment (vs 2.6% and 2.4%, respectively, for food-secure patients (p 0.001)). Compared to food-secure patients, those who were food-insecure had significantly higher rates of self-reported ED visits in the past 12 months: 18.8% vs. 33.6% reported at least 1 ED visit, respectively, and 5.2% vs. 16.4% reported multiple ED visits, respectively (p 0.001). Conclusions: In this analysis of SDOH data among patients seen in breast oncology clinic, FI was the most common social health risk reported, with nearly a quarter of patients with metastatic BC reporting FI. Racial/ethnic minorities were also at considerably higher risk for FI. ED utilization was significantly higher among food-insecure patients. Targeted interventions to reduce FI in at-risk populations are warranted to improve clinical and healthcare utilization outcomes.
