Background

Adults with glomerular disease have poor HRQL. However, the effect of race/ethnicity and SES on HRQL in this population remains largely unknown.

Methods

CureGN is a 70-center cohort study of patients with MCD, FSGS, MN, or IgAN/IgAV. We compared adult patient characteristics (demographics, disease duration/severity, medications, SES) across racial/ethnic groups. Multivariable logistic and linear regression models, created using best subsets and backwards selection, were used to examine associations between race/ethnicity and HRQL, as measured by missed school due to kidney disease and baseline PROMIS questionnaire items.

Results

Among 854 White, 220 Black, and 120 Hispanic adults, Blacks were most likely to have FSGS and had the highest urine protein, lowest serum albumin, and most severe edema. Hispanics were most likely to have IgAN/IgAV and had the lowest eGFR. Compared to Whites, Blacks or Hispanics were less likely to have completed college (48, 27, and 29%, p<0.001) or to have private insurance (76, 65, and 50%, p<0.001), and were more likely to be on medical/disability leave or unemployed (11, 23, and 24%, p<0.001). No racial/ethnic differences in missed work/school were observed. Blacks (but not Hispanics) had significantly worse global physical health, global mental health, and fatigue (table). However, after adjusting for SES and other factors, these differences in HRQL largely disappeared.

Conclusion

Among CureGN participants, Black or Hispanic (vs. White) participants were less likely to have completed college, to have private insurance, or to be employed. However, minority race/ethnicity was not independently associated with HRQL as measured in this study.
