1610 Background: Health care utilization and survival are correlated with social determinants of health (SDoH). Minimal data exists on the impact of SDoH within AYA Oncology. Methods: TriNetX, a de-identified healthcare research database retrospectively examined presence of SDoH billing codes among AYA cancer patients at various time points. Three cohorts were evaluated: ages 39. Cox proportional hazards regression was used to assess predictors of SDoH burden and survival in AYAs. Results: Baseline demographics were similar across cohorts. AYAs had higher baseline SDoH (25811, 5.2%) compared to 39 (58237, 1.8%). After diagnosis, AYAs had greater incidence of SDoH burden at 1y (OR 1.86 vs 39), 3y (OR 1.79 vs 39), and 5y (OR 1.8 vs 39). AYAs with any SDoH had higher occurrences of ED (OR 2.51) and ICU visits (OR 1.94). Within AYAs, baseline SDoH code was most prevalent in 30-39 age group, males, Hawaiian/Pacific Islanders, and lung cancers. The most common SDoH code in AYAs at diagnosis was homelessness at 57.8%. In a multivariate analysis examining incidence of SDoH in AYAs, positive associations were age 30-39; 1.95 (1.61-2.37), males; 1.49 (1.36-1.63), American Indian/Alaska Native; 4.44 (3.12-6.31), and presence of SDoH at diagnosis; 83.0 (71.6-96.3). Mortality in AYAs was associated with age 30-39; 1.81 (1.72-1.91), males; 1.58 (1.54-1.63), unknown race; 1.53 (1.48-1.58), and CNS tumors; 1.15 (1.06-1.25). Conclusions: AYAs with cancer have a high prevalence of SDoH burden at diagnosis and acquired. Within AYAs, age 30-39, males, and minority populations were most likely to acquire a SDoH code and have worse survival. The strongest association with both incidence of SDoH burden and mortality was a SDoH code at diagnosis. Table: see text
