Depression is common among individuals with CKD and associated with adverse outcomes. In the US population, prevalence is lower in older persons and varies with race/ethnicity. We studied factors associated with depression in a diverse non-dialysis CKD cohort, which could help to identify high-risk patients and disparities.


We identified adults with eGFR <60 for ≥90 days who received care through a safety-net health system from 2006-16. Depression was determined from ICD codes prior to or within 2 weeks of cohort entry. Comorbidities were identified using a similar method. We categorized CKD into stages 3A, 3B, 4, and 5. Race/ethnicity was recorded in 5 mutually-exclusive categories. We used multivariate logistic regression to analyze associations with demographics, comorbidities, and CKD stage, and calculated predicted probabilities and 95% CIs.


We included 13678 CKD patients of whom 39.4% were Hispanic, 40.9% black, 11.5% white, 5.9% Asian/Pacific Islander, and 2.2% other/unknown race. Depression prevalence was 11.6% overall, and 23.9% among whites, 11.1% among blacks, 9.8% among Hispanics, and 5.3% among Asians/PIs. Interactions between age and race/ethnicity, and between age and number of comorbidities were observed.


Depression prevalence varied with race/ethnicity, age, and comorbidities. Depression decreased markedly with age in blacks and whites, but not Hispanics. The association of comorbidities with depression decreased with age.
