Social determinants and health-related quality of life in a sample of diverse, low socioeconomic status cancer patients.

Abstract

In the United States, medically underserved populations, such as ethnoracially underrepresented groups, the limited English proficient (LEP), and the unemployed, may be vulnerable to poor functioning in cancer survivorship. The present study examined whether race/ethnicity, LEP status, and unemployment status were associated with poor health-related quality of life (HRQL) in four domains (physical, social, emotional, and functional well-being (FWB)) in a diverse, low socioeconomic status (SES) sample of cancer patients. The sample included 1592 ethnoracially diverse, low SES, primarily foreign-born adult oncology patients participating in an enhanced patient navigation program in 11 New York City hospital-based cancer clinics. This secondary cross-sectional analysis of program intake data examined bivariate associations between sociodemographic and clinical factors and poor HRQL (Functional Assessment of Cancer Therapy-General scores ≤70). Factors found to be related to poor HRQL (at p<0.05) were entered into logistic regressions with overall HRQL and the four HRQL subscales as outcomes. The Benjamini-Hochberg Procedure controlled for potentially inflated type-I error rate due to multiple comparisons. All three predictor variables (race/ethnicity, LEP status, and unemployment status) were significantly associated with increased odds of reporting poor FWB. Specifically, non-Hispanic White and Hispanic cancer patients had 2.7 and 1.5 times the odds of reporting poor FWB than non-Hispanic Black patients. The unemployed had 1.4 times the odds of reporting poor FWB than their employed or retired counterparts. Limited EP patients had 1.4 times the odds of reporting poor FWB than EP participants. Non-Hispanic Black patients evidenced significantly lower odds of reporting poor HRQL across all subscale domains compared with other ethnoracial groups. LEP and unemployed individuals were more likely to report poor FWB, which may indicate that the most marginalized cancer patients face significant barriers to adequate functioning. Interventions that promote functional abilities (i.e., activities of daily living, self-care, and work retention) and policies and programs that reduce systemic inequality and address social determinants of health may aid in improving HRQL for these underserved groups in survivorship. Non-Hispanic Black cancer patients were less likely than other groups to report poor physical, social, emotional, and FWB. Identifying protective factors in this group may aid in efforts to improve HRQL for all patients.
