Abstract

The objective of this paper was to determine whether there were any race differences in mobility limitation among PCa survivors, and understand the impact of socioeconomic status (SES) on this relationship. Data consisted of 661 PCa survivors (296 Black and 365 White) from the Diagnosis and Decisions in Prostate Cancer Treatment Outcomes (DAD) Study. Mobility limitation was defined as PCa survivors who reported difficulty walking a quarter mile or up 1 flight of stairs. Race was based on the PCa survivors self-identification of either White or Black. SES consisted of education level (i.e., less than high school, high school/GED, some college/associate, bachelors, masters/PhD) and annual household income (i.e., less than $50,000; $50,000–$100,000; greater than $100,000). Adjusting for age, marital status, health insurance, Gleason Score, treatment received, and time to treatment, Black PCa survivors had a higher prevalence of mobility limitation (PR = 1.58, 95% CI: 1.17–2.15) relative to White PCa survivors. When adding education and income to the adjusted model, Black PCa survivors had a similar prevalence of mobility limitation (PR = 1.12, 95% CI: 0.80–1.56) as White PCa survivors. The unequal distribution of SES resources between Black and White PCa survivors accounted for the observed race differences in mobility limitation. This work emphasizes the importance of SES in understanding race differences in mobility among PCa survivors.
