• Background Little is known regarding chronic kidney disease (CKD) in Hispanics. We compared baseline characteristics of Hispanic participants in the Chronic Renal Insufficiency Cohort (CRIC) and Hispanic-CRIC (H-CRIC) Studies with non-Hispanic CRIC participants. Study Design Cross-sectional analysis. Setting & Participants Participants were aged 21-74 years with CKD using age-based estimated glomerular filtration rate (eGFR) at enrollment into the CRIC/H-CRIC Studies. H-CRIC included Hispanics recruited at the University of Illinois in 2005-2008, whereas CRIC included Hispanics and non-Hispanics recruited at 7 clinical centers in 2003-2007. Factor Race/ethnicity. Outcomes Blood pressure, angiotensin-converting enzyme (ACE)-inhibitor/angiotensin receptor blocker (ARB) use, and CKD-associated complications. Measurements Demographic characteristics, laboratory data, blood pressure, and medications were assessed using standard techniques and protocols. Results Of H-CRIC/CRIC participants, 497 were Hispanic, 1,650 were non-Hispanic black, and 1,638 were non-Hispanic white. Low income and educational attainment were nearly twice as prevalent in Hispanics compared with non-Hispanics ( P < 0.01). Hispanics had self-reported diabetes (67%) more frequently than non-Hispanic blacks (51%) and whites (40%; P < 0.01). Blood pressure >130/80 mm Hg was more common in Hispanics (62%) than blacks (57%) and whites (35%; P < 0.05), and abnormalities in hematologic, metabolic, and bone metabolism parameters were more prevalent in Hispanics ( P < 0.05), even after stratifying by entry eGFR. Hispanics had the lowest use of ACE inhibitors/ARBs among the high-risk subgroups, including participants with diabetes, proteinuria, and blood pressure >130/80 mm Hg. Mean eGFR was lower in Hispanics (39.6 mL/min/1.73 m2 ) than in blacks (43.7 mL/min/1.73 m2 ) and whites (46.2 mL/min/1.73 m2 ), whereas median proteinuria was higher in Hispanics (protein excretion, 0.72 g/d) than in blacks (0.24 g/d) and whites (0.12 g/d; P < 0.01). Limitations Generalizability; observed associations limited by residual bias and confounding. Conclusions Hispanics with CKD in the CRIC/H-CRIC Studies are disproportionately burdened with lower socioeconomic status, more frequent diabetes mellitus, less ACE-inhibitor/ARB use, worse blood pressure control, and more severe CKD and associated complications than their non-Hispanic counterparts.
