Background

Race/ethnicity, disease severity/duration, and lower SES have been associated with poorer HRQL in children with glomerular disease; however, the relative importance of these factors has not adequately been explored.

Methods

CureGN is a 70-center cohort study of patients with MCD, FSGS, MN, or IgAN/IgAV. We compared pediatric patient characteristics (demographics, disease duration/severity, medications, SES) at enrolment 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 days due to kidney disease and baseline PROMIS questionnaire items.

Results

Among 515 White, 146 Black and 74 Hispanic children, Blacks were most likely to have FSGS/MCD and had the lowest eGFR, highest urine protein, lowest serum albumin, and most severe edema. Compared to Whites, Blacks or Hispanics were less likely to have private insurance (59, 35, and 32%, p<0.001), and their parents/guardians were less likely to have completed college (18, 7, and 10% of mothers, and 30, 12, and 12% of fathers, p<0.001). Racial/ethnic differences in HRQL were small (below the Minimally Important Difference of 3) and generally not statistically significant (table). No differences in missed school days due to kidney disease were observed.

Conclusion

Among pediatric CureGN patients, SES varied by minority status such that Black or Hispanic (vs. White) children were less likely to have private insurance and their parents received less formal education. After adjusting for SES and other factors, minority status was not associated with HRQL as measured within this study.
