Background:Childhood cancer survivors experience reduced physiologic reserve, or frailty, earlier and more frequently than peers. In other populations, frailty is impacted by one's neighborhood. This study's purpose was to evaluate associations between neighborhood characteristics and frailty in childhood cancer survivors.Methods:Participants in the St. Jude Lifetime Cohort Study with geocoded residential addresses were analyzed. Pre-frailty/Frailty was defined as having 1–2/≥3 of sarcopenia, muscle weakness, poor endurance, slow walking speed, and exhaustion from direct assessments. Neighborhood characteristics [e.g., access to exercise opportunities and healthy food, neighborhood socioeconomic status (nSES), and rurality/urbanicity] were determined using publicly available geospatial data. Nested multivariable logistic regression models identified associations between neighborhood characteristics and pre-frailty/frailty, adjusting for chronic health conditions, individual health behaviors and socio-demographics, and high-risk cancer treatment exposures.Results:For our cohort (N = 3,806, 46.79% female, 81.40% white, mean age 33.63±9.91 years), compared with non-frail survivors (n = 2,573; 67.6%), pre-frail (n = 900; 23.6%) and frail survivors (n = 333; 8.7%) were more likely to live in neighborhoods with decreased exercise opportunities (frail OR: 1.62, 1.26–2.09), reduced healthy food access (pre-frail OR: 1.28, 1.08–1.51; frail OR: 1.36, 1.06–1.75), and lower nSES (pre-frail OR: 1.31, 1.12–1.52; frail OR: 1.64, 1.30–2.07). Participants had 8% increased odds (95% confidence interval, 2%–14%) of being pre-frail/frail if they lived in “resource poor” neighborhoods as opposed to “resource rich” neighborhoods after adjusting for other pre-frailty/frailty risk factors.Conclusions:The neighborhood a childhood cancer survivor resides in as an adult is associated with pre-frailty/frailty.Impact:This study provides valuable information for creating interventions using neighborhood-level factors to mitigate frailty and improve health outcomes in survivors. |
