Racial Differences in Quality of Life Following Prostate Cancer Diagnosis

Abstract

To evaluate the effects of race on QOL while adjusting for subjective stress and religiosity among African American and white prostate cancer patients. Although racial differences in quality of life (QOL) have been examined between African American and white prostate cancer patients, it is not known whether differences exist while adjusting for psychological and cultural factors. We predicted that African American men would report poorer emotional and physical functioning after adjusting for these factors and that greater subjective stress and lower levels of religiosity would be associated with poorer well-being. We conducted an observational study of QOL among 194 African American and white men who were recruited from February 2003 through March 2008. Race had a significant effect on emotional functioning after adjusting for perceptions of stress and religiosity. Compared with white men, African American men (P = .03) reported significantly greater emotional well-being. Greater subjective stress was associated significantly with poorer emotional functioning (P = .0001) and physical well-being (P = .0001). There were no racial differences in physical functioning (P = .76). The results of this study highlight the importance of developing a better understanding of the context within which racial differences in QOL occur and translating this information into support programs for prostate cancer survivors.
